Will a url that is missing from the sitemap.xml be indexed?

Question

Search Engine Optimization

Actually a question in subj.
There is a site. There are a lot of things loaded through $('#id').load('/smth.html');and in general it is not very clear what browsers will see there. However, this is not important, since search engines will definitely not see the “juice itself” due to the fact that links to this “juice itself” are in these loadable blocks or in general by URLs that may appear after processing POST requests. The actual solution is to generate sitemap.xml , put it on the site, register it in robots.txt : Sitemap: http://www.mysite.ru/sitemap.xmland wait for everything to be indexed (or feed sitemap.xml to search engines via API).
Since it is known exactly which URLs search engines will not be able to see, the sitemap.xml generatorwritten (will be) only for "invisible" URLs. Writing a generator in general for all URLs is lazy. But there are fears that then the pages missing in the sitemap.xml will be ignored by search engines (or indexed with a different weight). Is it known how search engines treat pages missing from sitemap.xml ? Are they indexed at all?

Answer 1

They are indexed if they have internal or external links and search engines will get to these links. Of course, they can be indexed a little slower, but once I didn’t do a sitemap at all and everything was in the index))
