I changed my web address and add to new address to My Websites list and paste new codes in my website. But about 3 days. New domain is still pending status.
Sometime they will put ur request for along period till they have enough time to check your site. if it works well for their campaign they will approve your status immediately
You may inadvertently put your infolinks in an html tag that is not for content, would not make sense, and the browser (and infolinks) would ignore it. You would only put your infolinks before the </body> tag if you wanted the infolinks on the very bottom of the page. Maybe they want it at the beginning.
They will need time to review your site cuz they need quality trusted traffic to their advertiser too
