Check on your ad without affecting its performance
We know it's tempting, but it's best to resist the urge to search for your own ad on Google.com. Here's why:
- By performing searches that trigger your ad, you'll rack up impressions without clicks, which can lower your clickthrough rate and prevent your ad from appearing as often as it should.
- If you repeatedly look for your own ad using Google search but never click on it, you might stop seeing it entirely. That's because Google's system stops showing you ads that it thinks you aren't interested in.
Best ways to check on your ad
- Option 1: Use the Ad Preview and Diagnosis tool
See where your ad appears in search results for a particular search query. This is an easy way to check how your ad appears in context, and the tool provides the exact same results as a Google search without accumulating any impressions. Just visithttp://www.google.com/AdPreview, or click Ad Preview and Diagnosis in theTools and Analysis tab at the top of your AdWords account. After you choose the appropriate options at the top, you can see exactly which ads are being triggered by the search term you enter in any location. "
If it's a search campaign, use the Ad Preview and Diagnostics tool to see your ad. If your ad says "eligible", that means it only run on Google Search. When it says "approved" it will run on search partners as well.
You mentioned placements. That indicates you may be using a Display Network campaign. There is no good way to view your ad on the Display Network. Look on the Display tab to find out where your ads show up.
Best of Luck!
