Roll-Up Reporting and Custom Reports

Hi,
I am looking to compare the performance of three sites, all use the same Matomo tracking / events and custom dimensions.

Can this somehow be achieved via roll-up reporting and custom reports?

Optimal solution would be also to export the data automatically or access them somehow via a reporting tool.

Any suggestions appreciated.

Hi there,

If all the sites are using the same tracking code, they will all track into the same idsite in your Matomo. Are you sure the idsite in the tracking code is the same for each website?

Thanks,

Same as “same tracking framework and same site structur”.
But each site has it’s own ID and own TagManager.

And it is planned to have roll-up reporting and custom reports.

Each site will in this case track to their own idsite. To track the same custom dimensions across all sites they will need to be the same custom dimension id.
