Facebook’s Ad Exchange was only launched in September, after a beta test, but since that time it may be doing better than Google’s (News - Alert) ad exchange, according to a news report.

Carolyn Everson, Facebook’s vice president of global marketing solutions, was a source for the ranking, The Business Insider said.

The ad exchange is a bidding platform for advertisers, according to The Business Insider. It lets marketers use consumer data “to reach an audience on Facebook (News - Alert),” explained Facebook in a recent statement.

One source also said Facebook Exchange "quadrupled" the available market for advertisers who wanted to place ads in real time bids. Or, perhaps it relates to “the availability of total impressions” or the “supply of available ad inventory,” The Business Insider reported.

Facebook has said it is creating “a new $2 billion ad marketplace,” according to The Business Insider.

In other recent news, Nomura Equity Research predicts that Facebook Ad Exchange will add $450 million to advertising revenue for Facebook in the 2013 fiscal year, according to Value Walk. That equals a 9-percent increase.

The research firm says Facebook Exchange also provides higher advertising return on investment and click-through rates.

In other company news, Facebook employees were recently allowed to sell their stock, when a ban was lifted on insider sales, according to TechZone360. It relates to 234 million shares.

In August, a ban covering 271 million shares expired on sales by early investors and some directors, TechZone 360 added.

The sales come after Facebook’s problem-plagued initial public offering in May. The stock has been a disappointment to some investors.

Also, on Nov. 14, 777 million shares and stock options could be sold. On Dec. 14, 156 million shares held by early investors and some others could be sold. Then on May 18, 2013 some 47 million shares held by Mail.ru Group and DST Global, who were early investors, could be sold as well.
