Geotargeting
Google AdWords geotargeting may be the reason why your ad is not currently visible on Google. Geotargeting allows you to select countries, regions, and languages for each campaign. If your location is outside the targeted area, you won’t see your ad when searching for it. However, you can view your ad regardless of your location with Ad Preview and Diagnosis -tool by specifying the location.
Daily budget has been exhausted
AdWords displays your ads as often as possible without exceeding your daily budget. Once the budget limit is reached, your ad will no longer be shown for the rest of the day. It is also possible that due to a small campaign budget, the ad is displayed only intermittently to prevent exceeding the daily budget.
Scheduled Campaign
You may not find your ad if it is scheduled to appear only at certain times of the day or on specific days of the week.
Searching for your own ad on Google
If you repeatedly search for your own ad on Google without ever clicking on it, the ad may stop appearing for you. This happens because Google’s system recognizes your computer and stops showing ads that it perceives as uninteresting to you. Remember to use Ad Preview and Diagnosis -työkalua to view your ad as it appears in Google search results. This prevents impressions from accumulating when you try to find your ad.
