Google may not be showing you an accurate count of your indexed pages in the Google Search Console Index Status report.
This morning, Google’s Gary Illyes confirmed that the Google Search Console’s Index Status report is broken for the time being.
Some are noticing that the report, which shows webmasters how many pages Google has indexed of the site, has not grown in number, as they would expect. Some compared the index status report flat growth to that of the Sitemap report index count. And when the numbers don’t align and shift together, it may be a sign that one of the reports is wrong.
It turns out that the index status report is the one that is off and broken.
There is no estimated time for this report to be fixed, so for now, rely on your Sitemap index report in the Google Search Console.
