I dont know how you can gauge this one as there are too many variables.
Yeah sure, probably there are less people searching cos they have less money and it can wait, there is more competition and more people are having a go them smug selves with their QVC Bissell.
But the main influence on how many hits you get is what you have actively done yourself, so someone who has gone bonkers with their web marketing would think things are booming relatively speaking.
