Should I decrease my Adword budget?

Solicitating your valuable advice...

[SEOteam]

I heard from one of my webmaster friend that it is more profitable to run Ads on Overture than Adword if I am into selling some kind of products and not information...

He also told me that Google is rather an information portal, while Yahoo! is more business oriented. Commercial visitors know this, and therefore, I should decrease my Adword budget and proportionately increase budget on Overture.

I am in a fix... An advice will be great.

For myself - Yahoo just doesn't get the same conversions as adwords. But I guess the best thing for you to do is try it. What works for one - might not for another.
