I created an Ad to run in conjunction with the launch of a new site on March 1st. It is still under review 8 days later!! There is nothing in the ad that goes against the terms and condtions. Whats the point in Adwords If you cant run an ad when you want to. Searching G there are hundreds of posts on forums and blogs with others complaining about how long it takes to get a add reviewed, some people have waited months. Apparently the ads are checked manually and there can be backlogs (maybe they shouldn't have laid of loads of staff then). You would think with all their billions and whizzkid programmers they might have automated this by now.
