Duplicate ads warning from Google

[vidya]

Anyone familiar with the Google ad code? And how Google determines if an ad is a duplicate?

And how we can prevent duplicate ads from Google servers on our site?

We use 3 different size Google ads on our pages, and sometimes they'll put the same ad in the 3 different places.

Anyone know anything about how to prevent this?

They say they will turn off all Google ads on our site if we don't do something about this.

Thanks

No, there is no way to prevent duplicates. Sometimes I have gotten rid of them by removing one ad unit from the pages, which in theory increases the competition for the space. But there's no guarantees.

Who says they will turn off all Google ads on your site? Google's the one serving the ads, and the publishers have little control, so I can't see how Google would tell you that. Are you sure the warning means what you think it means?

Sigh, I'm confident you are a victim of unreliable robot. I'm sure you will receive an email from Google to ignore the warning, that is if you try to contact them.

My advice is to remove the offending page per Google's email so the robot will know you made the changes.

Check also your site design/coding if it conflicts with adsense's JavaScript especially if your site has a mobile version.

Can you please clarify? I didn't get one part.

Per example, if I have 3 slots on some webpage, I create 3 diff ad codes, one for each slot. I don't repeat the ad codes. Still I get sometimes repeated ads but, I'm using diff code on diff slots. I supposed that was the way everybody was doing things. Could they be talking about using repetitive ad code?

The same 3 ad codes or different 3 ad codes on the same page do not matter. They are fine. The OPs problem is different - his site code conflicts with adsense's code, which the robot detects as double-serving.
