Is there a simple way to only show ads on a WordPress page once it becomes popular?

I am looking for a simple way to minimize ads on a website I’m developing in WordPress by only showing ads (Google Adsense, to be precise) on the site upon a large influx of traffic. A large influx as defined as, say, more than 2x the normal hourly traffic (though the exact metric used to determine popularity is not that important to me).

In other words, if ever the site sees a huge influx of traffic, I would like to begin delivering ads (to attempt to cover the incremental server costs). Otherwise, I would like to keep the site ad-free for the casual visitors.

Is there a simple way, or plug-in, to do this in WordPress?

There is one wordpress plugin called “Search ads” that lets you do this. You can show adsense ads only to search engine users, which usually click on ads. As for regular readers from sources like bookmarks and manual address typing, ads will not show. Another plugin is “ad injection”.

If you wish to do adsense tracking on any website then you have to connect google adsense with google analytics profile. You have to use the tracking code of that profile on site which has adsense enabled.
