Piwik can be used to track an unlimited number of websites. Piwik can track pages on multiple domains and subdomains. Most users track from 1 to 10 websites, but some Piwik servers track more than 10,000 websites!
You must be logged in to Piwik as the super user to add a new Website. Click on Settings to access the administration area, then click on the Websites tab. This page is used to create, update and delete websites.
Click on Add a new website to create a new site in Piwik. The website form shows all the options you can specify:
These are the attributes that you can specify for each website:
You can also specify Piwik-wide values for these attributes at the bottom of the page. For example, you can set a list of IPs to exclude on all websites and URL parameters to always exclude from tracked page URLs on all websites.
To update a website, click on it, update one or several fields, and then press Save.
To delete a website, click on Delete at the right of the Websites screen. Please double check before deleting a website, since this operation cannot be reversed.
If you track several subdomains or domain names in the same Piwik installation, there are a few important JavaScript functions to use:
All Websites Dashboard is the best way to get an overview of what is happening on all your websites at once. You can check on the visits, unique visitors and page views, as well as view the sparkline showing the last few days evolution.

Each user can also choose, in the User Settings page, to load the All Websites Dashboard by default.
You can also automatically receive the All Websites Dashboard by email — daily, weekly or monthly.
In Email Reports > click on ‘Edit’ (or create a new scheduled report) > then Click on the checkbox ‘All Websites Dashboard’.
If you are building a web application, or if you use an exiting portal or dashboard, you can easily include the All Websites report via an Iframe. Click on the top menu Widgets link for more info. Click here to see the All websites dashboard Embed demo.
