Cross websites tracking

Hello !

I am tracking several websites (with different IDs) in Piwik and would like to analyse the cross sites visits (ex: During October, how many visitors have visited both Site A and Site B). I have enabled third party cookies.

Is there an API, Widget or MySQL query which would provide me with such report ?

Many Thanks in Advance !


No possibility ?

There is no such report, but you could query the data from the database if you use third party cookies (I have not done it before but should work!)

Hi Matt,

Many thanks for your feedback, I did run some query against MySQL and got some very interesting results.

One last question, what is the difference between “idvisitor” and “config_id” ? Which one should be the mot accurate for cross site tracking ?

Thanks !
