Following on from this post, you should have at least looked at your Google Search Console (you DID go and look, didn’t you? And if you realised you didn’t have a GSC, you got in touch with me so I could help you, right? 😉) and have an idea of which of your website pages aren’t indexed by Google.
In the example I gave you, 535 pages weren’t indexed for 7 reasons.
So let’s go through reason one:
Pages excluded by the noindex tag.
This means that either you or someone in charge of your site has specifically told Google not to index these pages.
It can, however, include pages you really do want to be indexed, so be sure to look through every so often.
1) Check through the pages listed to make sure that nothing is being restricted that shouldn’t be. If you see pages that shouldn’t be restricted, talk to your web developer or an SEO expert. Or me.
2) Make sure that pages such as /category, /tags, /author, /page1/2/3/4/etc are noindexed, as you don’t want them to appear in the search because of duplicate content issues. If you’re not sure how, send me a message and let me know what platform your site is built upon.
