Search console showing pages indexed but not in experience or enhanced?

Hello, when I observe Google Search Console (GSC), I notice that Google has approximately 1,300 pages indexed, which seems accurate. However, when I check for HTTPS, Core Web Vitals, and Breadcrumbs, the numbers are about half of that. Despite manually examining a page and seeing that it is indexed, with HTTPS, and with Breadcrumbs, could this discrepancy be due to a sampling issue?

It’s highly likely that the discrepancy you’re seeing is due to a sampling issue. Google Search Console doesn’t analyze all of your website’s pages at once; it takes a sample. This means that even if you’ve manually verified a page has HTTPS, Core Web Vitals, and Breadcrumbs, it may not have been included in the sample Google used for its reports. This is a normal part of how Google Search Console operates, and it’s not something to be concerned about.
