But my ads are still not displayed! What could be wrong? I have really checked everything.
Maartenk, it is next to impossible for anyone on this Forum to answer your question, because we can't see your account. So my best advice would be to contact AdWords support directly.
With that said, here are a few thoughts:
* Check your statistics for the date range of 'All Time'. Are there any impressions showing in the statistics? If so, then your ad is running. If not, then there may be an issue at work that AdWords support can assist you with.
* If there are impressions, but you are not seeing your ad, then there is good chance your daily budget is simply too low for your ad to show all the time.
* You may also want to check how your ad is targeted. Are you located in the region/state/country to which your ad is targeted? If not, then you won't see it.
The above are just a couple of common issues behind an ad not being seen, but I have no way to know if they really apply to your account. AdWords support, on the other hand, can take a look at your actual account and be very specific.
