I have already been writing several times about Bing and Yahoo gaining extra shares of the of searches in the US and this month they are again on the move while Google goes down a bit!

Bing (Microsoft sites) is now up at 11,8% and Yahoo! sites gained 0,8% to now 17,7% making the combined “MicroHoo” closer to the 30% – at 29,5%!
And Google lost a bit for the second month in a row -  now down 0,7% to a still massive 64,4% – but is still makes it more and more important to remember both Bing and Yahoo! in the Search Marketing activities!
