Maybe not the proper folder for this question, but if not I`m sure one of the mods will do the necessary for me. This is a question about using a bookmarking image, which mostly point to social networking sites. Does it help with Google and other search engines in any way? Does it encourage more traffic/loyalty/repeat visitors by having one of these on your site or blog do you think? Here`s what it says on this `add button` site. Also,do you have to register your site or blog at each individual social network site?
