I use both Overture and Google.
My experience is that Overture is much better
than Google Adwords.
I mean track the Overture clicks.
These people click on average 5 - 7 pages and convert
to buyers at 5%.
In contrast my CTR in Google is 1% and my convert to sales
is about 0.3% or LESS! Plus the google visitors
click less than three pages before they leave.
The main problem Overture has is expensive keywords.
All high traffic keywords are over a dollar
and most are in the $2-5 range, too rich for
Another problem is that they take 4-EVER to approve words,
and I have to re-submit the same word to them.
If you don't ride them like a horse, they never
get around to approving your keyword!
You get they worst excuses for why they do not admit a keyword, like "word not relevant." And the page 100%
about that WORD!
Google is pretty much on the ball.
