Go to Google Ads and sign in.
Click the Tools & Settings (wrench icon) in the top menu.
Under Shared Library, select Audience Manager.
Inside Audience Manager, go to the Custom Segments tab.
Click the blue + button.
Name your audience clearly (e.g., Visual Visitor Markets).
For Display campaigns, you can define custom audiences by:
Keywords/phrases: What people are searching for (or content they’re interested in).
Example: “car dealerships,” “marketing agencies”
URLs: Websites your ideal customers might visit.
Example: competitor marketing opportunity websites, dealership industry blogs.
Apps: Apps your audience may use.
Example: Entrepreneur or finance apps.
Google will then target people likely to be interested in these, not just people who searched those exact terms.
Click Save.
Your new custom audience will now appear in Audience Manager under Custom Segments.
When creating or editing a Display campaign:
Go to the Ad group settings.
Under Audiences, click Browse → Your Custom Audiences → Custom Segments.
Select the one you just created.
