If a bounty is added to a question, it is added to the featured/bounties tab. I was a bit curious whether having the question prominently displayed influences how high the question will appear in Google searches (and in other search engines).
Since this adds a link to the question to a new page (which is probably high ranked), my guess would be that there might be at least minor effect.
Question. Is it possible to find out in some way whether a bounty actually influences ranking of the post in search engines?
Motivation for asking about this. People use bounties for various purposes. Probably the most typical uses are to attract attention to a question which hasn't received satisfactory answer or to reward a nice answer. Some people use bounties as a way to attract more attention to what they consider the best content of the site (be it good questions or good answers) - this happens probably more often on big sites where interesting stuff might get easily drowned by a lot of basic question which are posted on the site every day. I suppose that it might be useful for user offering bounties to know whether they also have this positive side effect (especially when using bounties to promote good content).
