What Is a Facebook Ads Agency Account

An agency account is an advertising structure that allows marketing agencies to manage campaigns for multiple clients.

It is usually created using Meta Business Manager.

Main features include:

  • managing multiple advertising accounts;
  • accessing client campaigns;
  • controlling pixels and audiences;
  • monitoring advertising budgets.

This system makes advertising management more efficient and secure.

Advantages of an Agency Account

Using an agency Business Manager provides several important advantages.

  • centralized advertising management;
  • access to multiple ad accounts;
  • role-based permissions for team members;
  • better protection of client data.

Agencies can also manage campaigns for multiple brands simultaneously.

Step 1: Create a Business Manager

The first step is to create a Meta Business Manager account.

To do this:

  1. go to business.facebook.com;
  2. click “Create Account”;
  3. enter your company name;
  4. provide a business email address.

After this process your Business Manager will be created.

Step 2: Add an Advertising Account

Once Business Manager is created, you need to add an advertising account.

There are three ways to do this:

  • create a new advertising account;
  • add an existing advertising account;
  • request access to a client's advertising account.

Agencies most commonly use the third option.

Step 3: Connect Client Accounts

To manage advertising for a client, you need access to their advertising account.

To request access:

  1. open Business Settings;
  2. select the Ad Accounts section;
  3. click “Request Access”;
  4. enter the client’s advertising account ID.

Once approved, you will be able to manage their campaigns.

Step 4: Assign Team Roles

An agency account allows you to assign different roles to team members.

Main roles include:

  • Admin — full access;
  • Advertiser — campaign management;
  • Analyst — access to analytics.

This helps maintain proper control of your team.

Step 5: Connect Facebook Pixel

The Facebook Pixel allows you to track user activity on websites.

It helps you:

  • measure conversions;
  • build retargeting audiences;
  • optimize advertising campaigns.

To install a Pixel:

  1. open Events Manager;
  2. create a new Pixel;
  3. install the code on your website.

Step 6: Create Advertising Audiences

Facebook Ads allows advertisers to create several types of audiences.

  • Custom Audience;
  • Lookalike Audience;
  • Saved Audience.

These audiences help target the right customers.

Step 7: Launch an Advertising Campaign

Once the advertising structure is ready, you can launch campaigns.

The main steps include:

  1. choose a campaign objective;
  2. define the target audience;
  3. set the advertising budget;
  4. upload ad creatives.

The campaign will then go through Meta’s ad review process.

How Agencies Scale Advertising Campaigns

Marketing agencies use several strategies to scale advertising campaigns.

  • testing different creatives;
  • using Lookalike audiences;
  • increasing advertising budgets;
  • retargeting website visitors.

These strategies help improve results and increase sales for clients.

Common Mistakes When Setting Up Agency Accounts
