Facebook advertising has become costlier but the social networking site has cut down on the number of advertisements, media reports said.
"The average price per ad was 123 % costlier in the second quarter of 2014 compared to last year," Dave Wehner, Facebook CFO, said in the latest earnings call.
Facebook also displayed 25 % lesser ads but revenues from advertising still increased by 67 %.
"The price of ads correlates to the value that they create. We continue to focus on making those ad units better and better, more relevant and targeted for the people
who use Facebook, as well as for marketers," Wehner added.
A design change in April this year left lesser space for advertisement on a page.
The company said "people will see fewer ads on Facebook so some advertisers may see increased prices at auction".
