I've spent some time in the review queue lately, and I've noticed that quite a few bots/spammers try and sneakily hide links in answers/questions. Presumably they do this to boost the Google score of their website.
However, assuming they succeed (i.e. the community doesn't spot their spam, and it gets to stay), do these links posted to SE actually improve their Google rating?
What if the community deletes the answer/question (say, a few hours after posting)? Does it help the spammer in any way then?
