根据用户代理切换Google Adsense广告（移动还是常规）

Question

I'm optimizing a site so that on a mobile browser it only shows the mobile adsense ad, and on desktop it only shows the regular one. Problem is the google code leaves a white space where these ads are on the page.

I want to know if there is an easy way to programmatically insert the ad (JS) based on the user agent.

Thanks.

It's very simple, see Masquerading Your Browser for details on how the User-Agent header works. See also the HTTP specification .

You haven't said which server side language you're using. In PHP you would look at the value of $_SERVER['HTTP_USER_AGENT'] .
