Analyze in detail each SERP
You can study in detail the results of your keywords, to display the first 100 results. This allows you to study the progress of all sites that have positioned themselves, for the period of your choice.
You can view the SERP for the period of your choice, and thus see the evolution for each URL set.
You can see all the URLs that are positioned on each type of positions (P0, PAA, video blocks ...).
In this example Marmiton.org got the zero position only once, the other days she was acquired for Cuisineaz.com
