An SEO professional was concerned about technical improvements they were making with their blog, along with some of its structured data.
Since the end of October, the number of pages indexed by Google has dropped dramatically – approximately 25 percent – by about 500,000 pages.
For the pages that they have submitted, the submitted ones have dropped by 50 percent to over 50 percent.
They have done all the research they can imagine that would be relevant.
The one thing that they found is that if there is a review on a product page, or if there are no reviews on the product page, the Schema validator is unhappy because there was no review mentioned, but they are doing something wrong there.
That is the only large change they can think of that has happened that could cause the site to go from a slow but steady growth all year to a dramatic drop in the past two months.
Is there something they are missing that they should look at next?
John answered that just because structured data is not entirely valid on a page, this would not mean that Google would drop it from indexing. He believes this seems unrelated.
He continued: he is imagining that perhaps the SEO professional is looking at the report in Search Console, which shows all of these errors.
They are looking at them, and they say – “Well, I don’t really care about the markup there.”
John says that that is fine. It’s not a sign that Google thinks their site is bad, because the structured data isn’t valid.
Google just wants SEO professionals to know that, in case they want to use the structured data, that it isn’t working.
This would still not interfere with crawling or indexing or anything like that.
