I would absolutely definitely 100% have to agree with you on this and here is why.
1) Google allows you to choose the region your ads appear.
Overture forces every possible click on you, including those clicks that are from out of country.
2) Google lets you choose wether to be shown on affiliate/content sites.
Overture/Yahoo! forces every peice of crap click on you. ( From my analysis this system runs rampant with click fraud from out of country affiliates. )
3) Google has your ad up and running in literally minutes.
Overture requires someone to review your listing, and if it is declined gives you some rediculously vague reason why. Sometimes it takes weeks to get a certain keyword included because it takes them 2-3 days to review the listing every time you resubmit.
4) Googles customer service and responses are far faster and superior to Overture. When contacting google regarding some listings that were not appearing they got back to me within 4 hours.
When we contacted Overture we had to wait 2 days for our first response, and another 2 days for our second response. ( So much for paying $200 for preferential treatment, which is a total rip off in my opinion )
The only thing Overture has going for it is Yahoo.com. If yahoo.com was smart they would allow their advertisers to choose wether to be shown via their "Partners" websites or strictly on Yahoo.com. I think the overall quality of clicks their clients would receive would be better and in turn their bids would go up.
As you can tell I am a very dissatisfied Overture customer, unfortunately its the only way to get on yahoo.com.
Cheers and good luck.
