Hello,
Thanks for contacting us.
To index your search results pages, please navigate to WP Dashboard > Rank Math > Titles & Meta > Misc Pages and disable the Noindex Search Results option. After that search engine crawlers will be able to index your pages.
And you can also set a title for search results in the Search Results Title section.

Hope this helps. Let us know if you need any further assistance.
Thank You, but the seo title not showing on google? How to fix it?
Hello,
Thank you for getting back to us.
The title will be displayed based on the variables you have used in the search results title section.
However, please note that your internal search results are pretty much the last pages Google would want to send its visitors to. This is the reason we have this set to noindex by default.
Website visitors want to find what they’re looking for as efficiently as possible. If a user lands on a search results page, instead of a page that’s been updated to include helpful content, they may be left with questions.
Ideally, the user would land on a page that’s relevant, helpful, and easy to navigate, rather than a page that shows a list of products.
The links on a search result page are still very valuable, you definitely want Google to follow them. So, all links should be followed, and the robots meta setting should be: <meta name=”robots” content=”noindex, follow”>
We are looking forward to helping you more.
Thank you.
