Hello Matomo friends,
We have a long-time self-hosted Matomo instance behind a firewall to track our WordPress intranets. Our search engine is behind the firewall as well. We’ve noticed a steep decline in page hits since upgrading to Matomo on PHP7 (now on 3.11.0) from Piwik on PHP5 earlier this year.
Current experiments are showing that when an uninoculated user clicks on a search result, there is no page hit logged for the landing page in controlled tests. We are using a common footer across our WordPress sites that includes the tracking code, and we can see page hits on direct entry to WordPress URLs when we test in uninoculated browsers. However, if the click is referred from the search engine, we see no page hit even when we test well outside the 30 minute referrer window.
How do we troubleshoot this problem?
