Can't post images here, it's saying "Please, do not use live links to external resources."

My website indexing is very strange.

Will 1 weak link in the website influence the whole site like this? I tried manually indexing, and it seemed to work at first but as you can see in the screenshots (I will send if needed), it reverted back and again I get indexing issues.

What might be the problem? I am willing to pay nicely to whoever can make the site properly index again...

Has anyone tried SEO services from Fiverr? Are they any good?
