In February Google updated its algorithm yet again. Now the reason for this is up for speculation but Google has said its to make a better user experience. In Google’s eye, they would like every search to serve up exactly what the searcher is looking for. It’s earlier updates have always favored high quality content that creates a great user experience. I don’t think anyone would argue with that. I surely won’t or don’t. But this update also penalized many sites just because they or the company that they hired used certain blog networks to help get their sites higher up in the search engines. In fact, several networks have been de-indexed.
