Internet Explorer users are at least four times as likely to click on Web ads than Firefox users, a German advertising technology company said last week. The company, Adtech, found that during October and November, only 0.11 percent of Firefox users ever clicked on an ad, compared with around 0.5 percent of IE users. The percentage of IE users clicking on ads varied depending on which version of the browser was being used, the company said: from 0.44 percent of version 6.x users to 0.53 percent of version 5.5 users. The survey was based on 1,000 Web sites in Europe that use Adtech's ad server.<br /><br /> <i>[Ed: The interesting story here is the reasoning behind the differences.

It's a pity it doesn't clarify if they included adblocking FF users or not: With Adblock installed, I hardly ever SEE the ads, so of course don't click them. So would I have been counted, because I opened the page, or not counted, because I didn't download the ad?

I'm impressed that's even been reported as news. Aside from the ad-blocking features, most Firefox users are slightly more tech-savvy and less likely to think "Wow, a free iPod!" *clickety-click*...

Yes, but if advertsiers know that FF users won't click ads, they might stop trying to get past the popup blocker. If they think we're just as likely to click if we see the ads, then they'll try ahrder to bombard us with ads we can't block!

I'm betting Adblock is a major reason for this, particularly if the users are installing the FiltersetG lists. I know that Adblock is continually on the list of most popular FF extensions.
