How long backlink appear on Ahrefs?

Hi

I built link in a lot of web for a long time but there are some link appear. And they appear very quickly. I check the rest, they still appear on that website but I don't see any link on ahref. What does this mean?

Check the webpages if they are still indexed in Google. De-indexing can cause the backlinks to disappear from Ahrefs.

Aherfs does not show all the links as it's a third party tool and may not have crawled that links yet. If your backlinks are not showing on this tool that doesn't mean links are not indexed or crawled by Google. Check manually, if links are showing up in Google search then there is no need to worry!
