The Office of Fair Trading is investigating Overture and Espotting, after Espotting followed Overture's lead in a move to raise their minimum bid from 5p to 10p.
An initial complaint regarding Overture's price increase was dismissed by the OFT. However fresh complaints by the search engine marketing sector have caught the OFT's attention.
Overture and Espotting deny collusion, claiming PPC remains the cheapest type of targeted marketing.
The increase comes as no surprise to search engine marketing experts, who are long used to bidding up to £14 for highly competitive terms.
