If you want to select specific websites to show your ads, you can create an allowlist. If you want to ensure your ads don't appear on specific sites, you can create a blocklist.

A blocklist allows you to exclude specific websites where you don't want your ads to appear.
​
When you add websites to a blocklist, your ads will not be shown on those sites.

An allowlist allows you to select the specific websites where you want your ads to appear.

When you use an allowlist, your ads will only be shown on the websites included in the list. All other websites will automatically be excluded.

1. Go to your 'Tools' section and click the '+ Create New' button in the top right corner.

2. Select list type - block list or allow list.

3. Name your list.

4. Enter domains separated by a comma-, space, or line. Enter only the hostnames, for example, match2one.com. Do not use: 'http://', 'https://', nor 'www' before the domain name.

1. In the Campaign Setup, go to the 'Budget & Targeting' step and scroll down to the 'Advanced Targeting Settings'. Click on this option, and locate the 'Domains' setting.

2. By default we'll be targeting domains automatically, however, if you want to exclude (blocklist) or include (allowlist) specific domains, select 'Blocklist' or 'Allowlist' accordingly.

3. Under the selected option, you'll see a drop-down list with lists of domains already created in your account. You can also create a new list by clicking the '+ New Domain List' button. In the drop-down, select all lists you want to add to your campaign - they will appear below the drop-down menu and will be included in your campaign.
