Clickstreams or clickpaths represent the sequences of actions performed (clicks, etc.) and webpages visited by a website user.
By default, Piwik reports are in real time (learn more in the user documentation) when you are viewing reports for “today” or any date range that includes today. Piwik will look at all your logs for today in the database and process the reports every time that you request them.
By default, reports for today are processed every 10 seconds. The Piwik Super User can change this value in the “General Settings” admin panel. For high traffic websites, we recommend processing the reports once every hour (3600 seconds), which is a “near real time” approach.
Please read the Setup auto archiving page for more information.
Piwik also provides a real time view of your visits on your site… right now! You can see all new page views, actions and new visits coming to your site, refreshing automatically. This feature is enabled by the Live! plugin which is enabled by default in the Piwik dashboard (check out the demo).
I have custom needs for a new Piwik functionality, such as a new custom plugin or a new report. Who can build for me a quality solution to solve my requirements?
If you have custom needs and requirements, for example if you need a new functionality in Piwik, or a new report in your analytics dashboard, or even a new custom plugin, you can get in touch with the leading Piwik experts by filling in our form: http://piwik.org/development/
After you send in the form below we will check the requirements and will get back to you as soon as possible with a proposal and estimate.
We have created many quality solutions for Piwik clients over the years and we look forward to helping you.
The number of unduplicated visitors coming to your website. Every user is only counted once, even if he visits the website multiple times a day.
Unique visitors are determined using first party cookies stored in your visitor browser. When a same person visits your website on two different devices (for example their laptop and on their mobile phone) then Piwik will detect two unique visitors.
If the visitor’s browser does not accept the Piwik cookie (if they have disabled, blocked or deleted cookies), a simple rule of thumb is used to try to match the visitor to a previous visitor with the same features (IP, resolution, browser, plugins, OS, etc).
Note that by default, unique visitors are available for days, weeks and months periods, but unique visits are not processed for the “year” period for performance reasons. Learn how to enable unique visitors for all date ranges.
See also our glossary of analytics terms.
If a visitor comes to your website for the first time, or if he visits a page (or downloads a file) more than 30 minutes after his last page view, this will be recorded as a new visit. A Unique Visitor can make multiple Visits per day.
In the first visit, the visitor is a New Visitor. From the second visit (the same day or later), a Unique Visitor is a Returning Visitor.
You can change the 30 minutes value (session timeout) by overriding
[Tracker] visit_standard_length = 1800
in your config/config.ini.php file.
See also our glossary of analytics terms.
Entry page is the first page of a visit.
For each Entry Page URL, Piwik reports the number of Entrances (Visits that started on this page), Bounces (Visits that started on this page but left the website straight away) and Bounce rate.
See also our glossary of analytics terms.
The Exit Page is the last page accessed during a visit.
Piwik reports the top Exit Pages URLs, the number of Exits, Unique Pageviews and Exit Rate. Exit rate (sometimes called “Page Exit Ratio”) is the number of Exits from a page divided by total number of Page views of that page.
See also our glossary of analytics terms.
Super Users are the only users that can perform all administrative tasks such as adding new websites to monitor, adding users, changing user permissions, activating and deactivating plugins and even installing new plugins from the Marketplace.
By default in Piwik there is one super user which was created during the installation process. As of Piwik 2.1, you may give Super User permission to other users.
The Super User has superpower!
You can create users and assign them the ‘admin’ permission on a given set of websites. Users with the ‘admin’ permission can edit the website settings (Name, URLs, Timezone, etc.). They can also grant other users the ‘view’ or ‘admin’ permission on the website(s) the user has ‘admin’ permission.
Users with ‘admin’ permission cannot add other websites and users, and they cannot manage plugins.
The Super User can create users and assign them the ‘view’ permission on a given set of websites. Users with the ‘view’ permission can view all reports in Piwik for the website(s) the user is set to ‘view’. The user cannot add other users, websites, and they cannot manage plugins.
token_auth acts as your password and is used to authenticate in API requests. You can find the
token_auth by logging in Piwik, then click on your username in the top menu, then click the link “API” in the left menu.
token_auth is secret and should be handled very carefully: do not share it with anyone. Each Piwik user has a different
When a user changes its password, the
token_auth will be regenerated automatically.
Piwik lets you measure several websites within one Piwik server. Each website added into Piwik has its very own
ID Site (or
Website ID). To find out the
idSite value for a given website, go to Piwik, then click on “Administration” link in the top menu and go to the
Websites page. In this page you will find the list of all websites. The website ID is on the left of this table listing all websites (below the website name).
You can track as many websites as you like that are hosted on the same server as Piwik, or hosted on several external servers. Only the server that hosts Piwik needs to run PHP and MySQL.
- You have a website built in Java hosted on server1
- You have a website built in Python hosted on server2
- You can install Piwik on server3, and track visits from the two other websites
Note about https: Piwik automatically detect if the page being tracked is https (SSL) and would include the piwik.js in secure mode from your Piwik server.
Every night, if you setup auto-archiving, Piwik will run through the logs and compile all your reports for each day, week, month and year. How long the process will take depends on your traffic, number of visits and pages, on the number of websites you have setup in Piwik… and of course on your server performance.
For example, using version 1.3 on a single core duo2 server with 3GB of ram, Piwik archiving process takes about 2 hours for 400,000 pages per day (and more than 6,000 websites). We are constantly improving Piwik performance: making Piwik faster is a top priority. Stay tuned… or come and help us if you know how to design software to make it faster.
Also, if you have a medium or high traffic website, we would be interested to hear your experience with Piwik archiving. How long does archiving take for your traffic, how many visitors/pages, how many websites, what type of server; Please post your numbers in the High traffic Piwik servers forum post, and let us know by email.
For practical information about managing Piwik for high traffic websites, see this FAQ: Piwik web analytics for high traffic websites check list.
Why are there sometimes 0 visits, but some conversions recorded, for example for a Keyword, a Website or a Custom Variable?
Imagine the following use case:
1) User comes to your website via the campaign “Emailing November”, via a click on a link in an email tagged with Piwik (or Google Analytics) campaign parameters
2) He browses around and exits after 3 pages
3) He comes back the next day (on 2011-01-01), via a direct entry, and buys a product on your site (which you track as a Goal Conversion)
In this case, if you select the date 2011-01-01 in Piwik, it will show that the Campaign “Emailing November” did not have any visit on this day (because the user entered the website directly), but the conversion is attributed to the Last known referrer that the visitor used (which is stored in the first party cookie). On 2010-12-31, there will be one visit from the campaign “Emailing November” but no conversion on this day.
Piwik attributes conversions to the last seen referrer by default. How do I credit conversions to the first referrer instead?
When visitors convert a Goal, Piwik tries to attribute the conversion to the referrer that brought the visit to the site. Piwik will credit this Goal conversion to the last non empty referrer used by the visitor (ie. the last time the visitor came to the website with a referrer that was not a direct entry). In some cases several referrers can lead a same visitor to your website (eg. Search engines, Newsletter link). Piwik attribution model lets you choose whether to credit the conversion to the first referrer used or the last referrer used.
To add a new search engine in your Piwik server, you can use the ReferrerManager plugin which lets you manage Search Engines and Social networks.
The lists of Search engines and Social networks detected by Piwik are maintained in our searchengine-and-social-list project on github.
Since Piwik 2.16.0 definitions are automatically updated in Piwik installations using a scheduled task. This guarantees your Piwik uses the latest definitions.
You can read more about how to add/edit a search engine or social network definition in the README file of the repository.
(Piwik uses an icon for each search engine and social network, placed in the directory plugins/Referrers/images/)
Piwik provides two reports for your page views: Page Titles and Page URLs. A page title is the content of the HTML <title> tag. If your pages do not define this <title> Piwik will instead report “page title not defined” for the visits on those pages.
Piwik provides two reports for your page views: Page Titles and Page URLs. In some rare cases, a visitor’s browser will not let the Piwik Tag request the current URL (generally for privacy reasons). If Piwik could not request the page URL from the browser, Piwik will instead report “page url not defined” for the visits on those pages.
If all your pages report “Page url not defined” then there is a data tracking problem. Here are common reasons for this issue:
- 2) check that there is no automatic HTTP redirection on the piwik.js and piwik.php requests (for example via an .htaccess). 301 Redirection from
- 3) if you manually track file downloads using
_paq.push(['trackLink', 'https://mydomain.com/download.pdf', 'download'])for example, note that you must use a full valid URL.
- 4) If your pages are correctly tracked but you still don’t see any URL being tracked, please investigate/debug the issue with Firebug or ask in the forums posting your site URL so we can help you.
Piwik uses a special php function (gethostbyaddr) to request the hostname associated to a given IP. For example, the function would return “br76.comcast.net” and Piwik would categorize the visitor as using the provider “Comcast”. Sometimes however, for specific IPs or when the function times out, Piwik doesn’t know which provider the visitor is using and will simply report “Unknown”.
Some search engines (Google for all logged in users, DuckDuckGo, Firefox latest version now also removes keywords, etc.) may not specify the keyword used to reach your website. Piwik will report the keyword as “Keyword not defined”. It means that Piwik has detected that the visitor came from a search engine, but the keyword was not provided in the Referrer URL.
There is no way to access the keyword in this case, and no other web analytics tool can get this information either.
Of course you can! We love having people help us make sure Piwik is available to as many people as possible in a language they understand. Please see Piwik Translations for more information.
Yes, Piwik works well with any IPv6 addresses. Here is further information:
Tracking API will track users with an IPv6 address.
Visitor Log and other detailed user reports will display IPv6 addresses.
IP Anonymisation privacy feature will anonymise IPv6 addresses.
Geolocating IPv6 does not work very well: most IPv6 will not be accurately geo located. A few Ipv6 addresses may be geo-located when using the PHP or Apache geo location driver. IPv6 geo location does not work with the Maxmind PECL driver (issue). Geo locating Ipv6 addresses may improve in the future as Maxmind (our Geo database provider) improves the accuracy of their IPv6 databases.
Logs containing IPv6 addresses can be imported in Piwik without any issue and they will be correctly parsed, anonymised (when applicable), stored and processed.
Here is an example of an Ipv6 address:
To track your https pages correctly, your server hosting Piwik should work when called from https. You will need to buy a SSL certificate for your Piwik server.
Many Piwik users successfully use Piwik to report analytics of Ecommerce and SSL secure shops.
The Piwik tag detects the protocol of the page being tracked, and then automatically calls the normal http or secure https Piwik server.
To check whether your Piwik server works over HTTPS, go to:
https://url/to/piwik/piwik.php?rec=1&idsite=1 – if it returns a blank page it is working. If
https://url/to/piwik/piwik.php?rec=1&idsite=1 returns an error, please contact your sysadmin to ask her to enable SSL on the Piwik server.
On a related note, you can also force the Piwik login form to use secure SSL connections.
To ensure that your visitors and all their actions on SSL HTTPS pages will be correctly tracked in your Piwik, you need to check that your SSL Piwik Server is correctly configured.
Does Piwik support Google Analytics campaign parameters (utm_campaign, utm_medium, utm_source, utm_term)?
Piwik detects URLs tagged with Google Analytics campaign parameters. By default, Piwik offers two dimensions for Campaign tracking: name, and keyword. The parameters
utm_source are used as the Campaign name. The parameter
utm_term is used as the Campaign keyword. You can learn more about Tracking Campaigns in Piwik or head over to the URL Builder.
If you need to track more than two campaign dimensions in Piwik, for example if you want to enjoy the same campaign reporting as in Google Analytics, you can install the AdvancedCampaignReporting plugin available here on the Marketplace. AdvancedCampaignReporting plugin lets you track up to five Campaigns parameters (name, source, medium, keyword, content).
* you may choose to customise campaign parameters detected by Piwik.
* you can use campaign parameters in the query string
landing?utm_campaign=PaidSearch, and Piwik also detects campaign and keyword in the hash tag string
SKU stands for Stock-keeping unit. A Product SKU is a string representing the Product unique identifier in your Ecommerce shop: for example SKU for books might be the IBAN identifier for this book such as
8120725247. A given Product might change its name overtime, but the product’s SKU should always be the same. With Ecommerce Analytics, you can track Product SKUs, Product Names and Product categories and get interesting reports about their performance in our online shop.
- Each dimension has its own menu item under either “Visitors” or “Actions” making them first class citizen reports
- A single Custom Dimension report can be widgetized whereas it is only possible to widgetize all Custom Variables reports combined
- More metrics are available for Custom Dimensions in scope “Action” (Unique actions, Exit rate, Bounce rate, Average time on dimension, Average generation time) and the row actions Segmented Visitor Log, Overlay and Transitions can be used
- Custom Dimensions are easier to segment as the segment name will be the name of your Custom Dimension in the UI
- Custom Dimensions are more efficient as they need less storage and reports can be generated faster
- Custom Dimensions are easier to track as no scope and no name needs to be set
- Custom Dimension values in scope Action can be tracked automatically by extracting the value from the tracked URL or Page Title
- The name of a Custom Dimension can be changed at any time
- Values of Custom Dimensions are limited to 255 characters whereas Custom Variables are limited to 200
However, there is also a limitation. Unlike Custom Variables you cannot use the same slot/index for many different names or use cases. While for both Custom Variables and Custom Dimensions 5 slots in scope Action and 5 slots in scope Visit are available, you cannot use a specific slot of a Custom Dimension for something else. Once you have created a new Custom Dimension you can only deactivate it. Deleting a dimension and creating a new one is not possible. However, if you ever run out of available Custom Dimension slots you can make more available at any time. This just might take a while as it requires schema changes in the database.
In general we recommend users to use Custom Dimensions as we will deprecate Custom Variables at some point. With Piwik 3.0 Custom Dimensions will be most likely installed by default.
When I enable “Purge old logs” in the Privacy settings, how do I make sure that no historical data is lost?
If you enable ‘Purge old visitors logs‘ in the Administration > Privacy menu, Piwik will regularly delete your Visitor Logs from the Database. The Logs are used by Piwik to process Reports such as “Top Keywords”, “Top pages”, etc. If some old logs are deleted from your database, but reports have not been yet processed, the data will be lost forever.
We highly recommend that before deleting old visitor logs from your database,
1) you setup the automatic archive processing,
2) and run the
console core:archive console command until completion at least one time, making sure there are no errors during the execution.
This will ensure that all daily reports for each website have been pre-processed and the logs are no longer needed for these days.
Piwik custom variables tracking provides a powerful & easy way to track custom values and variables about your visits (for example “Username”, “Membership level”) or page views (eg. “Category:Sport”). You can track up to 5 variables for each Visit on your website. On top of these 5 custom variables for each visit you can also track up to 5 custom variables for each page view.
Learn more about Custom Variables Analytics.

To respect the privacy of your visitors, it is recommended to include the Piwik Opt-out iframe in your website. This iframe will display to your users a short text and let them opt-out in one click.
To find the code for the iframe, login Piwik, then click Administration and then click Privacy.
Here is what the opt-out iframe looks like:

To track visitors, Piwik by default uses 1st party cookies, set on the domain of your website. Cookies created by Piwik start with:
When you exclude yourself from being tracked using the cookie method, Piwik will create a cookie
piwik_ignore set on the domain of your Piwik server (which might be a third party cookie if Piwik is setup on a different URL from the website being tracked).
Piwik by default does not use third party cookies but you can enable a third party
_pk_uid cookie it if you wish.
Learn more about What data does Piwik track?.
In some countries, the law requests websites to provide a way for users to opt-out of all tracking, in particular tracking cookies.
[...] // Add this line before the trackPageView() call _paq.push(['disableCookies']); _paq.push(['trackPageView']); [...]
disableCookies(), or if you are importing server logs in Piwik which do not contain cookie information.
When cookies are disabled, some data in Piwik will be less accurate. Specifically…
- Ecommerce and Goal tracking attribution: By default, Piwik stores the website or keyword or campaign used to find the website in a cookie, so that we can credit this website when the visitor makes a conversion (Goal conversion or Ecommerce order). If the conversion happens in the same visit, Piwik will always credit the referrer (even if cookies are disabled). However imagine the following use case: the visitor uses a newsletter link tagged with a campaign, visits 5 pages on your website but does not buy. He then comes back 2 hours later directly typing your website URL (therefore a Direct Entry visit), then buys during this second visit. When cookies are enabled, Piwik credits the conversion to the initial Campaign. When cookies are disabled, the conversion is not attributed to the original newsletter link as this data is not available.
- Reports such as “Days since last visit”, “Visits by visit count”, “Visits to Conversion”, “Days to Conversion” will count all visits without cookie similarly to new visitors.
- User IP address (see also: IP anonymisation)
- Optional User ID
- Date and time of the request
- Title of the page being viewed (Page Title)
- URL of the page being viewed (Page URL)
- URL of the page that was viewed prior to the current page (Referrer URL)
- Screen resolution being used
- Time in local user’s timezone
- Files that were clicked and downloaded (Download)
- Links to an outside domain that were clicked (Outlink)
- Pages generation time (the time it takes for webpages to be generated by the webserver and then downloaded by the user: Page speed)
- Location of the user: country, region, city, approximate latitude and longitude (Geolocation)
- Main Language of the browser being used (
- User Agent of the browser being used (
From the User-Agent, we use our Universal Device Detection library to detect the browser, operating system, device used (desktop, tablet, mobile, tv, cars, console, etc.), brand and model.
Some information is also stored in first party cookies and then collected by Piwik:
- Random unique Visitor ID
- Time of the first visit for this user
- Time of the previous visit for this user
- Number of visits for this user
(Note: it is possible to disable tracking cookies)
You may also configure Piwik to track optional information about your users or how they are using your website and apps:
- Custom Dimensions
- Custom Variables
- Site Search
- Viewing and clicking on Contents
How does Piwik detect unique and returning visitors? (with User ID, Visitor ID from cookie and/or fingerprint)
This FAQ explains how does Piwik Tracking API detect unique visitors, and returning visitors, depending on how the Tracking API is used.
When a visitor views a page or screen, Piwik will attempt to detect whether this request belongs to an existing visit, and/or whether the visitor has visited the website before.
How does Piwik detect whether the visitor is known?
- If a User ID is set, either via
setUserIdin your favorite SDK or via
&uid=in the Tracking API, this User ID will be converted (hashed) into a Visitor ID hexadecimal string. The hashed User ID becomes the Visitor ID. We look first for visits where the
log_visit.idvisitormatches this Visitor ID (User ID). If no visit is matched, we look for visits where the
log_visit.config_idmatches the visitor fingerprint.
- When a Visitor ID was manually set in the Tracking API via
&cid=(see: Tracking API reference for
cid), we only look for visits where
trust_visitors_cookiesis set to 1 (see: FAQ about
trust_visitor_cookies), and a visitor ID is found either in first party cookie
_pk_id(see: first party tracking cookies) or in the third party cookie (see: enabling third party cookies), we only look for visits where
log_visit.idvisitormatches the visitor ID from cookie.
- Otherwise when a visitor ID is found in a first party cookie or in the third party cookie, we look first for visits where the
log_visit.idvisitormatches the visitor ID from cookie. If no visit is matched, we look for visits where the
log_visit.config_idmatches the visitor fingerprint.
- Finally, when there is no visitor ID found in first party cookie (nor in the third party cookie) and a visitor ID was not specified via
&cid=, we only look for visits where the
log_visit.config_idmatches the visitor fingerprint.
In all cases, when “looking for visits” in the past, we look back
window_look_back_for_visitor seconds. By default, Piwik will look back 30 minutes (default value for
window_look_back_for_visitor INI setting). This setting can be changed: learn more.
If a visitor is found, then Piwik will assign the current request to this existing visitor, either by updating the current visitor’s visit or by creating a new visit when appropriate (learn more about what Piwik considers a visit)
How does Piwik detect a returning visitor?
A visitor will be marked as ‘Returning visitor’ when:
- she has visited the website at least once before this visit (this can be detected via the ‘visit count’ and ‘first visit time’ and ‘last visit time’ found in tracking cookie and sent to Tracking API as
- or she has visited the website but with tracking cookies deleted or lost, Piwik still managed to find a previous visit from this person (applicable when customising
- or she has purchased an item on the website before this visit (according to the ‘last ecommerce order date’ found in tracking cookie and sent to Tracking API as
When measuring activity with the Piwik Tracking API, the following HTTP headers may be used:
Host– the hostname of the HTTP request, the hostname of the Piwik server.
Referer– used to track Referrer information such as website, search engine, social network.
User-Agent– used to detect the information about browsers, operating system, devices by device-detector library.
Cookie– when Opted-out from tracking, or when Third party cookies are used.
Origin– used when cross-origin resource sharing is enabled.
Accept-Language– used to detect the users’ language
X-Forwarded-For– when Piwik is setup behind a proxy
DNT– used to detect whether a visitor’s device is opted-out from tracking (Piwik privacy)
Yes, Piwik 2.15.0 and newer can be used with CSP. However, you cannot use the standard tracking code generated by the Tracking Code Generator in the Piwik UI as it is not allowed to use inline scripts when having CSP enabled. CSP is a security concept to prevent cross-site scripting (XSS) attacks as well as related attacks.
Instead make sure to put the tracking code into files like this:
<script src="http://example.com/piwik/piwik.js" async defer></script>
piwik.js should be loaded from your Piwik server and
tracking.js should contain the actual tracking calls like this:
var idSite = 1; var piwikTrackingApiUrl = 'http://example.com/piwik/piwik.php'; var _paq = _paq || ; _paq.push(['setTrackerUrl', piwikTrackingApiUrl]); _paq.push(['setSiteId', idSite]); _paq.push(['trackPageView']); _paq.push(['enableLinkTracking']);
Make sure to specify the correct
idSite if needed and to replace the Piwik Tracking API URL. You can build this URL by appending
/piwik.php to your Piwik domain.
If you load
piwik.js from a different domain make sure to allow the Piwik domain like this:
An example response header looks like this:
Header set Content-Security-Policy "default-src 'self'; script-src 'self' http://example.com; style-src 'self'; frame-ancestors 'self'; frame-src 'self';"
If CSP should work in all browsers you might have to add further headers. At the time of writing this article you might as well need to set
X-WebKit-CSP for Safari and
X-Content-Security-Policy for Internet Explorer support. Read more about Content Security Policy.
When the Piwik server is unavailable (down) how does this affect my websites loading speed and tracking data collection?
It may happen that your Piwik analytics platform service is down / unavailable temporarily. Here are some important notes:
Your websites will still load correctly and should not be affected by any problem on the Piwik side. In the worst case scenario where Piwik server(s) are completely down and do not serve the
If for a few minutes or a few hours, your Piwik service is down, you may have lost data for this time period. In some cases, it is possible to replay most, or all, of the lost data. Learn more about how to replay your Piwik web server access logs and restore your tracking data that was not imported during the outage.
The phpMyVisites website, documentation, downloads will always stay live but we strongly encourage users to start using Piwik as soon as possible (check out the online demo or the list of Analytics features).
Piwik is an analytics platform that comes with a set of APIs (Tracking API and Reporting & Management API), a web application with a modern user interface, but Piwik also comes with a powerful console tool.
To use the console, connect to your server running Piwik using SSH or your server console. The tool is a script located in Piwik’s root directory and called console. You can run it with the command:
The Piwik console has many uses and new commands are regularly added to the console. By default, Piwik has commands to enable and disable plugins (
plugin:deactivate), modify the config.ini.php file pragmatically (
config:set), clear the cache (
cache:clear), run the archiver (
core:archive), delete old log data (
core:delete-logs-data), invalidate specific old reports (
core:invalidate-report-data), run the scheduled tasks (
scheduled-tasks:run), update Piwik system and database after the files were updated (
core:update), enable the development mode (
development:enable), run the system check diagnostics (
diagnostics:run), open and watch the content of the Piwik log messages (
log:watch), and many others.
List all of the commands available on your Piwik server by running:
Plugins you use from the Marketplace may also add new console commands. For example the CustomDimensions plugin will add new console commands to list information about custom dimensions (
customdimensions:info) or to let you add and remove custom dimensions (
