Welcome to the Q&A Forum

Our team is stumped and we are hoping some of you might have some insight! We are seeing a drop in Europe organic revenue and we can't seem to figure out what the core cause of the problem is. What's interesting, the high intent traffic is increasing across the business, as is organic-attributed revenue.  And in Europe specifically, other channels appear to be doing just fine.  This seems to be a Europe high-intent SEO problem. What we have established: Revenue was at a peak in Q4 2017 and Q1 2018 Revenue dips in mid-late Q2 2018 and again in Q4 2018 where it has stayed low since Organic traffic has gone up, conversion rate has gone down, purchases have gone down Paid search traffic has gone up, conversion rate has gone down slightly, submissions have gone up Currency changes are minimal We cannot find any site load issues    What we know happened during this time frame (January 2018 onward): Updates to the website (homepage layout, some text changes) end of April 2018 GDPR end of May 2018 Google Analytics stops being able to track Firefox Europe is a key market for us and we cant figure out what might be causing this to happen - again, only in Europe - beyond GDPR and the changes we've made on our site is there anything else major that we're missing that could be causing this? Or does anyone have any insights as to where we should look? Thank you in advance!
