For those of you that regularly use Alexa or A9 as your search engine of choice, you may have noticed some changes lately. While these search engines used to base their results off of Google's, they now use results provided by Live.com.
One of the other big developments that some members of the Internet marketing community have pointed out is that the search function on Amazon.com, the owners of A9 Search, no longer shows AdWords ads in their results. Amazon was a big supplier of ads in Google's distribution network. I will try and provide more information on this as it becomes available.
