One SEO professional was worried about their site that has approximately 20-30,000 pages. It’s mostly a directory service, and they have unique content. They are also worried about using numbers as content.
However, they ended up adding noindex to approximately two thirds of those pages.
The reason for this decision was because they wanted to focus more on what Google looks at.
A month or so after they implemented this, less than 1 percent of these pages were indexed.
They are seeing “discovered but not indexed” errors for mostly all of their pages in Google Search Console.
This issue has their team scratching their heads.
Even after making these tweaks, they don’t appear to be wrong to them.
They believe it’s possible that they are restricting themselves a little with the canonical setting, but the settings don’t really look wrong.
Ultimately, they seem to believe it’s a site quality issue.
This happens at approximately the 22:59 mark in the video.
