Google said this “affected many properties” and thus, you should probably double-check your coverage reports for the sites you manage over the next few days.

Why we care. If you provide reports to clients or stakeholders on the index versus not indexed pages on a site, then you will want to make sure to annotate your reports for clients. Hopefully, this does not add to any stress you already have with your SEO job.
