Why there is /page/2/ url for my website?

Hello,

Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.

The page you are seeing is a pagination of your homepage. Please navigate to WP Dashboard > Rank Math > Titles & Meta > Misc Pages and enable the Noindex Paginated Pages:

Wait for Google to crawl your pages again and the page should be removed from the search results.

You can also request the removal of the URL here: https://search.google.com/search-console/removals

Please refer to the following guide for more details: https://developers.google.com/search/docs/advanced/crawling/remove-information

Hope this helps. Let us know if you need any further assistance.

Hello,

That option will noindex the paginated pages of your archives like post categories, blog page, etc. If you want to do that then you can enable the option.

Hope this helps. Let us know if you need any other assistance.

Thanks.
