Issues with Post Indexing After Switching from Yoast to Rank Math

Hello,

We apologize for the issues you are facing with post indexing after switching from Yoast to Rank Math. Thank you for providing detailed information about the steps you’ve already taken; it helps us understand your situation better.

Since you’ve ensured that the "noindex" tag is not set on your posts and that your sitemap is submitted correctly, let’s go through a few additional checks:

1. Check Rank Math’s Titles & Meta Settings: Ensure that the default settings in Rank Math are not set to "noindex" for your posts. You can do this by navigating to WordPress Dashboard → Rank Math SEO → Titles & Meta and checking each tab to confirm the settings are as per your preference. If any posts need to be indexed, make sure to select the respective "Index" Robots Meta tag.
   

2. Verify Global Settings: Double-check your global settings at WordPress Dashboard → Rank Math SEO → Titles & Meta → Posts/Pages/Products/CPTs to ensure they are configured correctly.

3. Instant Indexing Module: Since you have activated the Instant Indexing module, make sure you are using it correctly. After publishing a post, hover over the post on the Posts page and select the Instant Indexing: Submit Page option to notify search engines immediately.
   

4. Check Robots.txt File: You mentioned that your robots.txt file doesn’t block Googlebot, but it’s worth double-checking that there are no disallow rules preventing indexing. You can edit your robots.txt file in Rank Math at WordPress Dashboard → Rank Math SEO → General Settings → Edit Robots.txt.
   

5. Google Search Console: After making these adjustments, monitor your Google Search Console for any updates or errors related to indexing.

If you continue to experience issues after these checks, please reply to this ticket with any specific error messages you see in Google Search Console or any other relevant details, and a human agent from our support team will assist you further.

We hope this helps you resolve the indexing issue soon!
