Yahoo president Sue Decker has defended the company's strategy for internet marketing which will see it form an agreement on search engine marketing with Google.

Writing on the company's blog, she refutes allegations that the deal will see the end of Yahoo's sponsored search business as well as the more serious claims of price fixing - which have come from as conscientious and competition-encouraging company as Microsoft.

Dealing with the first point, Ms Decker says that there will merely be a "backfill" of Google adverts where Yahoo is "not delivering enough value".

"If Google can deliver that value where we currently don't, then everyone wins - including the advertiser and the consumer."

On the more serious note of price fixing, she points out that it is advertisers who set prices through bidding in auctions and the agreement will see a "new opportunity to bid for placement".

"They will bid for what they think this opportunity is worth at prices that produce positive ROI."

This means it will be good news for everyone - consumers, advertisers, orphans, world peace and of course Yahoo and Google.

But is Yahoo being truthful in what it is saying, or will the critics continue to scrutinise the deal?
