Yahoo! intends to make use of Google’s search technology to include ads alongside search results, after picking the search words out itself. The purpose is “to increase its ad performance for less popular, long-tail searches” according to Adweek.

The report predicted that if Yahoo! uses Google digital resources and prices of less common “tail” searches, it will “increase search costs along the board,” AdWeek reported.

According to the report, Yahoo!’s keyword ad prices may go up by about 22 percent, if the company decides to capitalise on profits from the keywords it shares with Google.

Ad buyers may be worried because Google may become a search ad monopoly of sorts if Yahoo! decides to give its search business to Google.
