How to connect Google Ads to an existing workspace

1. In the sidebar, under Setup, click Ad accounts. With several protected entities, pick the entity in the switcher under the workspace name first.
2. Click Add ad account, or Connect Google Ads if the page has no account yet. Both open Add an account.
3. On the Google Ads row, click Continue with Google and sign in.
4. Tick the Google Ads account or accounts to protect and click Finish.
5. The Google Ads page of Setup > Ad accounts lists your account, and its Campaigns tab shows each campaign's Protection switch. Tapper starts detecting and filtering invalid traffic.

Check the tracking template

Tapper sets its tracking template at account level. A campaign, ad group or ad with its own template can hide its clicks from Tapper. See Fix campaigns, ad groups or ads that override Tapper's tracking.

The full steps are in Connect Google Ads and Add another ad account to an entity.
