Anyone experiencing a Decline in sale for April?

Decline In Sales

[IntrigueLearning]

I am just wondering if the decline in sales is just related to our products as a whole or if there has been a general decline in sales for all PPC campaigns. We have experienced a drop in sales of 40% in the past couple of months and I was just wondering if others have experienced a dramatic decline for their search engine campaigns aswell.

We are seeing Impressions, CTR and conversion all falling out of bed for April and continuing in May. These are are well established campaigns and no amount of the usual tweaks is havng any effect.

I cannot help suspect that the glut of Adsense chasing spam sites are heavily diluting both Google and Overture result.
