Why are my pages not being indexed?
How To Fix Indexing Issues
So you’ve generated pages they aren’t brining traffic. That typically happens if your pages aren’t indexed by search engines. First of all, make sure you:
Generated MPG sitemap for each project and submitted it to Google Search Console
Created links on your website pointing to the generated pages. Your pages must be linked to for search engines to understand the importance of the pages. The closer the page is to the homepage in clicks, the more important the page is.
