Aoife White, Google Blocks Smaller Ad Rivals, Competitor Says in EU Antitrust Complaint, Bloomberg, Feb. 22, 2011:
1PlusV sent a complaint to the European Commission today claiming Google refused to allow so-called vertical search sites to use its advertising service, the French web publisher said.
Google also appears to give preferential treatment to its Google Books pages in searches and includes some websites in its search results without their consent, 1PlusV said in a statement. …
By showing Google Books pages in its search results, the company may be violating the search engine’s own anti-spam rules, 1PlusV said.
I have not seen the complaint itself. I am curious about the connection between Google Books results and Google’s anti-spam rules.
