The powerful Row Evolution feature shows you the current & past metric data for any row in any report. You can view how metrics for visits that use firefox or visits that came from Google or almost anything else change over time. Additionally, you can compare these trends with the trends behind other rows to gain even more insights (e.g. comparing the use of two different keywords over time).
This feature can be used to:
- See how keyword use changes over time, either due to changes in SEO or lack of searches (by viewing the evolution of visits from a specific keyword).
- See if more and more people are visiting your website on a mobile device (by viewing the evolution of visits of a row in the Mobile vs. Desktop report).
- See if your copy is losing its effectiveness over time (by viewing the evolution of revenue for a page).
- See if your visitors visit some pages more on certain months (by viewing the row evolution of a page while viewing metrics for a month).
Row evolution can show you trends within reports not just with regard to a couple metrics, and is thus unique within all of Piwik. Only through this feature can you see how visits to specific pages change over time or how visits with a specific browser change over time.
You can use row evolution to gain a nuanced understanding of how your web traffic changes and will change, and with the combination of another powerful feature, Annotations, you can record these insights for later recollection.
