When searching Google is it possible to check your Google Ads are showing without triggering any impressions. You can do this by adding the following to the end of the google search URL:
&adtest=on
Or by visiting the following URL to enable Google Ads test mode:
https://www.google.com/search?adtest=on
This allows you to browse without triggering impressions. Once you have completed your testing you can turn test mode off by adding the following to the end of the Google search URL.
&adtest=off
Or by visiting the following URL:
https://www.google.com/search?adtest=off
You can also use the following parameters to test ads from different geographical locations, where “gr” equals the country code and “gcs” equals the location name or postcode.
&gr=UK&gcs=London
Here are some examples of the URLs for different locations:
London, UK
https://www.google.com/search?adtest=on&gr=UK&gcs=London
Birmingham, UK
https://www.google.com/search?adtest=on&gr=UK&gcs=Birmingham
Postcode PO11AT (in Portsmouth, UK)
https://www.google.com/search?adtest=on&gr=UK&gcs=Po11at
I hope this is helpful.
