A WebmasterWorld thread reports that eBay is back at it again, bidding on every possible search term under the sky or rather under the Internet. This is upsetting to many advertisers, who can feel a big hurt from eBay taking up an additional spot in the ad space available on the search results.
Let me take you back a bit in history. Back in June 2007, Google and eBay got in a bit of a fight. eBay pulled their ads from Google, it estimated to hurt Google at about $26 million in ad revenue, per month. eBay then decided to resume the ads but not at the level they once had it at.
Now, over a year later, there are reports that eBay has stepped up their campaign with Google search ads. Advertisers at WebmasterWorld are complaining big time, calling eBay's tactics simply unprofessional. They are reportedly running up bid prices without improving any relevancy.
Welcome back eBay - I don't think searchers or advertisers are that happy to see you, at least not from the early discussion.
