I've submitted links to a number of social bookmarking sites. Even though a few weeks have passed, very, very few of them show up in Yahoo's backlinks or in Google Webmasters. Any tips on how to get these links to be recognized?
Most don't show up. Doesn't mean that G is not counting them. Also - it takes a while for G to index you backlinks.
