This could have come from a number of sources, but the most likely candidates are: - the June Core Update to Google's algorithm - the switch to Mobile First Indexing - missing meta-descriptions - other changes to your site. I did a partial crawl of your site (my crawling tool is limited to 500 objects), and I found a number of missing meta-descriptions. In the first attached CSV file, you will see that the meta-description of a number of pages is only a period. A couple other pages have an English meta-description. If we look at some key pages, like the top landing page for the "pneumonie" query, we see that its meta-description is a ".", and that it's and tag does not use the word "pneumonie". The SEO for this key page could certainly be strengthened. The top landing page for "alzhemier" also does not have a real meta-description. The same is true of another page that you lost a lot of traffic from. For all three of these pages, the volume of traffic generated in the past four months compared to the period before fell by about 75%. Did these have meta-descriptions before and they were accidentally removed? If not, then the changes to Google's algorithms are probably hitting you harder for the lack of meta-descriptions than it was before. As you can see in the screenshot below, your traffic from your top 10 search queries has dropped dramatically (This is for the French version of the site). The number of impressions has dropped on these terms often by more than an order of magnitude. [image: image.png] You can see in the metrics below that your click-through rate has actually improved. The problem is that your average position has fallen dramatically, and with it, your total impressions is a fraction of what it used to be. [image: image.png] The box above is for all traffic. In the box below, you can see that for "alzheimer", you dropped from 7th place to 46th place. That's a move from the first page to the 5th page. [image: image.png] In terms of how to fix this, aside from the meta-description issue previously flagged, generally I would generally advise to improve mobile experience and page speed, but you are doing decently on both fronts. Google has detected no mobile errors, and functionally your site loads quickly, even though Google has flagged a number of issues (see my previous email). The only other error Google has flagged is that your logo is missing from the structured data of some pages. Fleshing out the structured data on a page is one way to improve ranking.
