If your web page is blocked with a robots. txt file, its URL can still appear in search results, but the search result will not have a description. Image files, video files, PDFs, and other non-HTML files will be excluded.

In this blocked robots.txt case URL can still appear in search engine results, but the search result will not have a description. Image files, video files, PDFs, and other non-HTML files will be excluded. If you see this search result for your page and want to fix it, remove the robots.

'Indexed, though blocked by robots. txt' indicates that Google has found your page, but has also found an instruction to ignore it in your robots file
