What Are Domain and Page Locking?

Domain Locking and Page Locking are security features used on agency ad accounts to protect your advertising assets from misuse. These features help avoid account bans, unauthorized access, and policy violations by tightly controlling which domains and pages can be used inside a specific ad account.

1. What Is Domain Locking?

Domain Locking means your ad account is locked to the domains approved at the time of account creation.

You can run ads only for that specific website, and no other domains can be used inside the account.

Why this is done:

• Prevents advertisers from switching to risky or non-compliant domains
• Protects the ad account from sudden policy violations
• Ensures better delivery stability
• Keeps account quality high

2. What Is Page Locking?

Page Locking means your ad account is allowed to use only the pages approved at the time of account creation.

You cannot change or add new pages.

Why this is done:

• Protects the ad account from being linked to unknown or unsafe pages
• Ensures compliance with Meta’s identity & transparency policies
• Prevents unauthorized people from attaching random pages

3. Why Locking Is good?

Locking helps maintain:

• High trust score
• Lower chance of bans
• Protection from advertiser mistakes
• Protection from hacks

This is one of the reasons agency ad accounts stay more stable than normal accounts.
