I use Blind Search a lot recently. It fetches search results from three major search engines: Bing, Google and Yahoo. It shows results to you and than asks what results you like the most. I found that most often I am satisfied with Yahoo search results. For example, searching for "magento set product type programmatically" showed two first results in Yahoo where I got most answers to my questions. Bing was #2 and Google was #3.
This is not a single example. I find that Google relelvancy becomes worse and worse. It is much harder to find what you are really looking for. Blind search shows me that Yahoo is now better than Google and Bing is nearly the same as Google.
Will Google loose the battle?
