Looking everywhere for your ad but still can't find it? If you have a Search ad, you can look for your Search ad with the Ad Preview and Diagnosis tool. It can help you confirm that your Search ad is running without affecting your impressions (which will lower your click-through rate). You can also hover over the speech bubble in the "Status" column of the Ads tab, next to your ad to see more information about its status. If your ad isn't showing, the tool will tell you why and will offer tips to help get your ads up and running.
One primary reason you may not see your ad when searching for your campaign keywords is your budget. If your AdWords campaign has spent it's daily budget, Google will stop showing your advertisements on the web. For example, say you're searching for your ads at 5PM, but your budget was spent by 3PM. You won't see any more ads because your daily ad budget had been spent.
We don't recommend trying to find your ads. It will most likely increase your ad impressions and decrease the CTR (click-through rate), which can hurt the quality score of your Google AdWords account. It's also important to not click on your own ads as you are personally "paying per click" for the ad campaign.
