Welcome to the Q&A Forum

Hi, I'm building the extension for Chrome, which should show me the status of the indexability of the page I'm on. So, I need to know all the methods to check if the page has the potential to be crawled and indexed by a Search Engines. I've come up with a few methods: Check the URL in robots.txt file (if it's not disallowed) Check page metas (if there are not noindex meta) Check if page is the same for unregistered users (for those pages only available for registered users of the site) Are there any more methods to check if a particular page is indexable (or not closed for indexation) by Search Engines? Thanks in advance!
