• We already have a review feature in Matomo with the thumbs up/down next to certain features. The feedback goes to us and we always read them and try to improve things based on it and listen in general. When there was a thumbs up, in the sentence that says "thank you..." it would be good to also motivate users to leave a review on a feedback site like Capterra, TrustRadius, G2Crowd, ...
• On the help page we could add a section "Like Matomo? Please give us a review... " and link to the same sites...
• Maybe after - for example - 50 logins, we could also show a popup (or 90 days whichever happens first) asking to leave a review with choice [Remind me later, Don't remind be again] . If remind me again is selected, we would maybe remind again in 90 days? or earlier? Or maybe there are better ways without being annoying? Also instead of a popup it could be a nice looking full page and a "next/continue" button...

This should be added to the Feedback plugin.
