AdWords used to be my best traffic. but now?

i used to make my best conversions and dollars on Google. But now they suck

[EvilDan]

I have just over 40 different traffic sources for my websites

Google AdWords used to be number 1 for traffic quality based on ROI

But in the last few months that figure has dropped AdWords to about 23 on my list of traffic sources

No matter what I do I just cant seem to get them back to their old glory

Has anyone else seen this, and does anyone please have any ideas as to why?

I read another article here about Google changing the Broad match affected other users ROI (see [webmasterworld.com...]

Help anyone?

Hi Dan - How does Google rank among your 40 in terms of volume of traffic - then & now?

And what about conversion rates? Have they changed much over time, or is it just that CPC has increased?
