This has always struck me as both annoying and amusing - many people believe that they can build an online reputation by randomly leaving active links in posts of blogs they visit.
It's true that incoming links to your website and blog can improve your page ranking, thus your online visibility. It's also true that leaving comments on other blogs can help to build name recognition and boost traffic for your website and blog.
Do you really think that people who have a general interest in healthy food or bridal dresses are looking for a personal injury lawyer located in Atlanta?
Gosh. Why didn't I think of that?
Relevancy people. Relevancy. The difference between an effective linking strategy and spam is relevancy.
