Updated September 2026: Yes, one Google Ads account can advertise more than one website. The important policy rule is that ads inside the same ad group must use the same display-URL domain. If you advertise Site A and Site B, separate those domains into different ad groups or campaigns.
For unrelated businesses, separate Google Ads accounts under a Manager Account are usually cleaner for billing, access, reporting and account-level risk management.
The Core Google Ads Domain Rule
Google requires the landing-page domain and display URL to be consistent, and Google’s ad-group guidance states that ads and keyword URLs in one ad group should use the same domain—including paused ads.
That means this is valid:
- Campaign A / Ad Group A → example-a.com
- Campaign B / Ad Group B → example-b.com
But mixing example-a.com and example-b.com inside one ad group is not the structure I would use.
Can Multiple Domains Be in the Same Google Ads Account?
Yes. The account itself can contain campaigns and ad groups that lead to different websites, as long as the individual ads, destinations and account behavior comply with Google Ads policies.
When One Account Can Make Sense
- The websites belong to the same legal business.
- Billing is shared.
- The same internal team manages all properties.
- Reporting can be separated cleanly by campaign.
- Conversion tracking is configured correctly for each domain.
When I Prefer Separate Google Ads Accounts
I generally prefer separate accounts when the websites represent genuinely different businesses, clients or billing entities.
- Separate billing: cleaner invoicing and payment ownership.
- Separate access: each business gets the right users without exposing unrelated campaigns.
- Cleaner reporting: conversions, budgets and goals do not get mixed.
- Different business identities: verification and policy context stay easier to understand.
- Operational risk isolation: account-level enforcement can interrupt all campaigns in one account, so unrelated businesses are usually safer operationally when separated.
Use a Google Ads Manager Account for Multiple Businesses
If you are an agency or manage several separate businesses, a Google Ads Manager Account (formerly MCC) is the normal structure. Each client/business can have its own Google Ads account while you manage them centrally.
This does not mean you should create replacement accounts to get around a suspension. Google’s Circumventing Systems policy prohibits multiple-account abuse used to bypass enforcement.
Conversion Tracking Across Multiple Websites
Plan measurement before you combine domains in one Ads account. Each site may have different conversion actions, values and customer journeys.
- Name conversions clearly by website/business.
- Use the correct Google tag/GTM setup on each domain.
- Separate lead and sale goals.
- Do not accidentally make a low-value conversion from Site A the bidding goal for Site B.
- Use cross-domain measurement only when the customer genuinely moves between domains as part of one journey.
Final URL and Redirects
Your ad’s final URL should lead to the intended destination and use the same domain users expect from the displayed URL. Avoid cross-domain redirects that make the ad appear to send users to one business while actually landing them on another.
Example Structures
One company, two related websites
A company owns a main corporate site and a separate ecommerce site. One Ads account can be workable if campaigns, conversion actions and domains are separated clearly.
Agency managing five clients
Use five client Ads accounts under a Manager Account rather than putting five unrelated client websites into one Ads account.
One advertiser suspended, then creates a new account
Do not use another account to bypass the suspension. Fix the underlying policy problem and use Google’s appeal/review process.
2026 Checklist
- One domain per ad group.
- Keep different sites in separate campaigns/ad groups.
- Use separate accounts for unrelated businesses when practical.
- Use a Manager Account for agency/client management.
- Keep conversion goals and billing clear.
- Do not use cross-domain redirects deceptively.
- Never create extra accounts to bypass policy enforcement.

Final Takeaway
Multiple websites in one Google Ads account are allowed when structured correctly. The practical question is not “Can Google do it?” but “Does combining these websites make billing, measurement, access and policy management clearer or messier?” For unrelated businesses, separate accounts under a Manager Account are usually the cleaner choice.
