A pagination loop is when a web page returns the same results for different URL parameters. This can happen if a site’s pagination is not configured properly, or if there are multiple pages with identical content.
Pagination loops can be bad for SEO because they can cause search engines to index duplicate content, which can hurt a site’s ranking. Also, if a pagination loop is not fixed, it can keep visitors from being able to navigate through a site properly.
If you think your site might have a pagination loop, you can check the HTML source code of your pages to see if the same content is being loaded on different URLs.
