Unwanted calls are the calls you receive from Google users to inquire about the products or services that may differ from what you offer.
When you're running call-only ads or call assets, Google shows your ad against a specific set of keywords that you provide when setting up your campaign. People can click your ads or assets, and initiate a phone call to your business. However, you may receive unwanted calls if your ad appears in search results for keywords that aren’t related to your business. Learn more about where your ads can appear
Reasons for unwanted calls
If you're receiving unwanted calls after adding your phone number to a Google Ads campaign, it might be because your call-only ad or call asset is showing as a search result for a general keyword, and the lead was not sufficiently qualified.
Example
A home security provider bidding on the keyword “security” may receive unwanted calls from ad searches such as “social security”. Similarly, a home insurance provider who targets the keyword “insurance” may receive unwanted calls from users looking for car insurance.
Actions to avoid unwanted calls
You can improve your keyword list by adding terms and phrases that suit the specific needs of your business. Revising your keyword list will help you better control when your ad is shown in search results. Try removing general keywords that may cause your ads to appear in unrelated searches.
