Coverage dropped below 70%
As was said above by @keyplr this is all part of their big push to cleanup the ad space. It has a lot of facets (including the Chrome browser ad blocker and the Ad Experience report). It's going to be a rough ride for the next few months.
You need to look deeper for commonalities. The pages that had extreme ad failure...
are they not visited often?
Are these pages not included in your sitemap.xml file?
Are these pages not updated often?
Are the secure (HTTPS)?
Do these pages have other active links very close to the ads?
etc.
The way I'm interpreting this is that Criteo doesn't have the same issues with showing an ad on an uncrawled page that Google/Adwords does.
You're probably benefiting from sites like mine not getting coverage we normally do.@gorin_sis -that thought had crossed my mind ;)
