Lets say I have a site and I place it on my signature. I make 100 posts and receive 100 backlinks for my site. Then I take the site out of my signature. After a while, will I lose all those 100 backlinks for my site?
Intreresting question. I'm willing to bet that caching may have something to do with the answer...but Im not certain. I hope someone can give us a reply.
you miss all the links, all 100 backlinks are gone. but it takes time to show the un-indexing of backlinks by search engines. anyways you enjoy the traffic
Any inbound links that has been removed are lost back links and will no longer count in the next back links update.
If you remove link from sigs, backlinks will also remove but after the googlebot crawl that particular thread/backlink. It may take few days to few months depending on the crawler.
