Hi @mgonera

Thanks for the report. It works in this way "by design". In Piwik, when a visitor visits a page, the page "before" this pageview is assumed to be the previous page that was "last seen" by the user. So when opening two pages in new tab, for the second loaded tab, Piwik will consider that the page "before" (the referrer page) is the first tab.

To change / fix this, we would need to change some logic deep into the tracker:

• how the referrer page is assigned. Right now it's simply done by reading log_visit row, to get the last seen idaction. We would need to change this and look which was the idaction for the given Referrer URL.
  • there would be some performance overhead as we need to select the idaction that corresponds to the referrer URL
  • tracker code: https://github.com/piwik/piwik/blob/2.13.1/core/Tracker/Visit.php#L169-178
  • note: archiver code that processes Pages following site search, is here: https://github.com/piwik/piwik/blob/2.13.1/plugins/Actions/Archiver.php#L107-118
