Refresh a Div that has a Google ad inside it

The new Google DFP 'tags' allow specifically 'ad refreshing for AJAX'

refresh

pubService.refresh(slots) Refreshes the specified array of slots on the page with new ads.

Parameters:

array slots - Optional array of slots to refresh. If not supplied, all ad slots are refreshed. Example:

var slot1 = googletag.defineUnit("/1234567/leaderboard", [728, 90], "div-1").addService(googletag.pubads());

var slot2 = googletag.defineUnit("/1234567/skyscraper", [160, 600], "div-2").addService(googletag.pubads());

// The call to refresh fetches a new ad for each slot

googletag.pubads().refresh([slot1, slot2]); http://support.google.com/dfp_sb/bin/answer.py?hl=en&answer=2372721&expand=pubservice_details#refresh

I know I'm a year and a half late to the party, but... It's possible that the problem with the ads is that they are using document.write (Ad servers are notorious for this, but I don't know if AdSense uses it or not.)

If that's the case, I have a library that can help: writeCapture.js. Example:

$('#ads').writeCapture().html('<script src="whatever-your-adsense-code-is"> </script>');

That's using jQuery, but there is also a standalone version.

As for whether it's a TOS violation... Gmail changes ads dynamically, so it can't be that bad. As long as the content is changing too, I would think it was OK.

As both of the other answers state, refreshing your AdSense advertisements automatically isn't allowed. I understand that you only intend to refresh the ad in response to user action, but it still isn't allowed, even though it should be!

Remember, the reason why you want to update the advertisements is so that you can show new ones. Displaying an advertisement is called an "impression." When you use code to refresh the ads, you are automatically generating ad impressions.

AdSense Program Policies state (emphasis mine):

Invalid Clicks and Impressions

Clicks on Google ads must result from genuine user interest. Any method that artificially generates clicks or impressions on your Google ads is strictly prohibited. These prohibited methods include but are not limited to repeated manual clicks or impressions, using robots, automated click and impression generating tools, third-party services that generate clicks or impressions such as paid-to-click, paid-to-surf, autosurf, and click-exchange programs, or any deceptive software.

Refreshing your advertisements is a violation of the letter of the rule against generating impressions. With that said, I think any reasonable person would agree that refreshing advertisements in an AJAX app in response to user behavior (e.g. in response to a click) isn't a violation of the spirit of the rule.

For example, imagine rewriting your entire app to stop using AJAX. That's clearly a worse experience for your users (it's slower, the page flashes on every click, the page can't dynamically update in the background), but, by a technicality, it's not a violation of the AdSense Program Policies.

Clearly Google meant to prohibit automatically replacing the advertisements every five seconds (creating a "slideshow" of advertisements). Google also meant to prohibit making your site look more attractive to advertisers by appearing to have more visits than you actually have. I'm sure they didn't intend to prevent you from designing a high-performance AJAX website... but unfortunately sometimes rules have unintended consequences.

Of course, as you originally pointed out, you CAN still refresh your advertisements if you embed them in an iframe and modify its location. (Here's how to use iframes in an AJAX application to refresh AdSense.)

You rejected iframes in your initial question, perhaps because you knew that using iframes would violate Google's policies... but if you insist on breaking the rules, you might as well break them all the way! ;-)

Ultimately, I think you'll find that generating impressions this way isn't worth the risk: you'll "refresh" the ads only to find that Google is just showing you the exact same ads as before.
