A few days (or months) back, buying links was all search engine optimization was about. However, now Google has added a new dimension to search engine optimization by claiming to take care of all sites that are involved in buying and selling links aimed at boosting pagerank and positions in organics. In fact, there is a form available at Google using which sites involved in selling / buying links can be reported. It seems Google has already done something to sites that are openly in involved in text link brokerage. Many of these sites are appearing deep inside the pages even for their business names. Even directories seem to have taken the punch. Whether this is really intentional or a form of Google dance-nobody knows for sure.
