Facebook Hosts 1 in 4 Display Ads -- But Is Anyone Seeing Them?

Americans on the Internet saw 1.3 trillion display ads in the third quarter alone this year, according to new data released by comScore.

That's a 22 percent increase over the same time in 2009, with Facebook leading the pack. Almost one quarter -- 23.1 percent -- of all display ads were on Facebook, adding up to 297 billion ad impressions in the third quarter alone. Those are big numbers, but what do they really mean for advertisers?

As the average American on the Internet is hit with a whopping 6,000 display ads per quarter, or 65 ads a day, are they still effective?

It's hard to say. On the one hand, display ads such as those on Facebook can be highly targeted to a specific customer base in a way that was only dreamed about previously. On the other hand, of course, you're competing for attention with so many other ads that users begin to display ad blindness. How many ads do you notice on Facebook when you're on there? How many do you click on?
