For websites that rely primarily on display advertising to generate revenue, there are a number of opportunities to squeeze a bit more juice out of existing traffic. We’ve covered a number of these topics previously, including link units, sponsored CAPTCHA, and affiliate marketing. This article explores another option that has been proven to add to the top line–but that has some potential downside risks as well.

Today, we’re talking pop-ups. If you spend any time online, odds are you come across these quite regularly. In most cases, sites use them to promote their own products. Here’s an example from FamilyCircle.com, promoting a subscription to its magazine:
Similarly, here’s a screenshot from Time Out Chicago, encouraging visitors to sign up for newsletters:
Finally, below is an example from the Chicago Tribune’s website. Notice that this ad opens in a separate window from the site, and that it contains a third party ad (in this case, a pretty spammy one):
The Tribune no doubt decides to run this type of ad because it makes quite a bit of money by doing so (without cannibalizing their more traditional on-site banner ads). For publishers willing to host this type of experience, there can be a big opportunity to generate some incremental earnings here.
When you hear “pop-up ad”, one of the first words that comes to mind is probably “annoying.” But another accurate description is “effective.” You may be annoyed to see them appear when browsing the web, but the fact is that they accomplish their goal of getting an advertiser’s message across to visitors.
Given this effectiveness, pop-ups can be a great way to make a bit of additional revenue. Engagement and click rates are generally high, which means advertisers are willing to pay a premium to appear in these positions. Generally, the effective revenue per thousand impressions for a pop-up will be 2x or more that of a standard banner ad.
However, given the “annoyance factor” that comes along with these, you’ll also need to be cautious in your implementation. Visitors who see a pop-up when they come to a site generally close it out and continue reading. But some will be scared off entirely, and navigate away from the site. The odds of this undesirable outcome go up with the frequency of the pop-ups; the more ads you show to a visitor, the more likely they are to navigate away from your site (and potentially avoid returning in the future).
There are ways to make these ads a bit less obnoxious and intrusive. Forbes presents what is essentially a pop-up ad a bit differently, on its own page and accompanied by an interesting quote:
This accomplishes the same purpose–getting the advertiser’s messaging front and center–but isn’t as annoying because there is at least some content on the page (it helps that it’s pretty compelling and interesting content, even if it is just a brief quote).
If you’re using AdSense on your site as many publishers are, it’s important to be aware of the terms and conditions around pop-up units. Specifically, you’re not allowed to place AdSense ads in any window “that is not initiated by a user’s click.” Similarly, AdSense ads can’t go in any window that doesn’t have a back button or other navigational controls. Basically, don’t serve AdSense ads in a pop-up window (you also can’t have AdSense ads anywhere on sites with more than three pop-ups).
If you think there’s an opportunity to use pop-up ads on your site, you have a couple options. If you’re dealing directly with advertisers, you can invest some development resources to enable your ad server to display these ads directly (here are a couple tutorials that may be useful).
Alternatively, you can farm out the job to a third party network / technology partner. One of the biggest in the space is Undertone Networks; they can do just about everything you need to get up and running, though they’ll take a cut of any revenue you generate.
If you do decide to try out pop-up ads, here are some suggestions:
Pop-up or “interstitial” ads represent one of many opportunities available for publishers to make a bit of extra money from their existing traffic. The challenge here is finding a balance between incremental revenue and user experience; there will inevitably be a temptation to maximize your short term earnings, but it’s important to always keep in mind the long-term detriments to doing so.
