Scaling your Meta Ads agency: How to scale a marketing agency sustainably
Article Content

As a Meta ads agency owner, there comes a time when you start thinking about scaling. You may want to bring on more clients, grow your existing accounts, or do both, and the excitement of what’s possible is undeniable. But before you jump in, it’s important to ask yourself: Are you truly ready for this step?

In this article, we’ll walk you through scaling on two levels: first, evaluating how you can scale your business in a sustainable way, and second, optimizing your ads to save you time on repetitive tasks while improving results. 

Both approaches are key to scaling your business because they give you the freedom to either focus on new clients or strengthen your relationships with those you already work with. 

Are you ready to scale? Key factors to consider as a Meta ads agency

Project capacity

How much work are you handling right now, and how much could you take on with your current resources? You need to know what your breakpoint is. It’s the first thing to figure out because it will help you see if you have room to bring in new clients or take on bigger projects with your existing Meta clients.

Use a time tracking tool to see how much time you and your team are spending on each client. And don’t just track the hours; add tags or notes to each record so you know whether that time is going to admin tasks, client communication, or actual work in Meta tools.

It might take a little effort upfront, but it’s worth it. You’ll get a clearer picture of your bandwidth, spot any time-sucking bottlenecks, and find ways to streamline your workflow so you can take on more client work.

Financial capacity

Do you have the budget to invest in scaling? More importantly, is your income steady, or does it fluctuate a lot?

Not every campaign will be a winner right away, so having a financial cushion is key. If a few clients left, would your agency still be in a good place? Before going all in, take a step back and optimize your finances. Look at your tools, processes, and expenses—cut anything that’s not pulling its weight. The goal is to be clear on your financial runway.

Things won’t always go as planned, and that’s okay. What matters is having a solid financial foundation so you can adjust when needed. The more prepared you are, the smoother scaling will be. 

Agency processes 

Scaling your Meta ads agency means more customers, projects, communication, and likely more team members to manage. Ask yourself: if your workload doubled overnight, would your current processes still work? Or would you have to start addressing the inefficiencies as they appear, when things get busy?

Large agencies didn't get where they are by having every SOP pat down from the beginning. They adjusted—and adapted—along the way, part by part. Optimizing your workflow might mean automating repetitive tasks or better training your team to improve efficiency. For example, if you’re spending too much time creating ad visuals or struggling to get access to client ad accounts, those are clear opportunities for improvement.

Before you scale, make sure your processes are solid. Without tested, efficient systems in place, you’ll end up managing chaos instead of growth.

Overcoming the most common blockers to scaling 

As you can see, the inability to use your resources efficiently – like staff, time, knowledge, and cash flow – can be the biggest barrier to scaling. 

Spotting and removing bottlenecks, whether from unnecessary manual work or costly tools, can free up valuable time and resources, which you could redirect to focus on scaling.

We also know from experience that a lot of agencies and freelancers have problems with getting access to clients’ ad accounts, which hinders scaling. Reasons vary from not knowing who the admin is, to technical glitches and confusion over permission levels and roles. Not to mention, clients sometimes miss your request entirely, leaving your agency hanging in limbo. This issue alone can make scaling your marketing agency nearly impossible.

You can avoid all of these scenarios with Leadsie. Our access automation tool lets you create and send a unique link to your new clients. All they have to do is log into their Meta accounts and confirm access.

Now that we’ve discussed how you can prepare your agency for growth, let’s look at a couple of practices you can use to optimize and scale your Meta ad campaigns.

Strategy #1: Set up correct ad exclusions

Using the right exclusions isn’t just about optimizing your budget, it’s also essential for campaign effectiveness. Without exclusions, your ads may keep targeting the same people, limiting your reach and wasting opportunities to attract new customers.

If you create an ad set with no exclusions or use Advantage+ without them, Meta will prioritize warm audiences, i.e., people who have already interacted with your brand. This happens because Meta is designed to get you the lowest cost per purchase or lead, and warm audiences are more likely to convert. While this can drive quick wins, it also creates a cycle where your ads are repeatedly shown to the same group instead of reaching new prospects.

One simple way to check if this is happening is by monitoring your ad frequency. If an ad set has a frequency of 2x or more, your ads aren’t being delivered to new audiences, they’re just circulating among the same people.

Important update: Starting March 31, 2025, detailed targeting exclusions will no longer be available. Meta states that advertisers who don’t use them see, on average, a 22.6% lower conversion cost. However, you can still refine your targeting using custom audience exclusions and audience controls in your Advertising settings.

Here are the exclusions you can still select from: 

Current customers 

To stop your ads from targeting existing customers, you can exclude them in two ways:

  • Email list – upload a list of your customers' emails to create a custom audience.
  • Custom audience from purchases or leads – use your pixel data to exclude people who have already made a purchase or signed up.

For the best results, use both methods to ensure your ads focus on reaching new potential customers rather than those who have already converted.

Traffic 

You’ll also want to exclude past visitors to keep your ads focused on fresh audiences. You can set exclusions for 30, 90, or even 180 days (the maximum allowed).

A 30-day exclusion is a common choice, but some advertisers prefer a longer window. It depends on your strategy and how often you want to re-engage past visitors versus reaching entirely new prospects.

Engagement

If you want Meta to focus just on new audiences, exclude engagement. This prevents ads from showing to people who have already interacted with your brand, whether through ads or organic content.

To set this up, go to Audience Manager in Meta and create exclusions for:

  • Website traffic & purchases (via pixel data)

  • Customer lists (via uploaded email lists)

  • Engagement (separate exclusions for Facebook and Instagram)

In your ad sets, add these exclusions to keep prospecting efforts strong. Meanwhile, your bottom-of-funnel campaigns can retarget engaged users separately. With proper tracking, you’ll ensure a steady flow of new traffic, which is essential for scaling successfully.

Funnel exclusion

In your funnel, Top of Funnel (TOFU) targets new people who have never heard of your brand. Bottom of Funnel (BOFU) focuses on those who've interacted with your brand, like past visitors or purchasers.

To scale effectively, allocate around 60% of your budget to TOFU and the remaining 40% to BOFU. You can adjust this depending on your strategy (e.g., up to 80% for TOFU during peak times like Black Friday).

This budget split works best if you have the right exclusions in place to prevent Meta from showing too many ads to users already in the BOFU stage.

Custom Audience exclusions

This is a separate subset of exclusions you can set if you use Custom Audiences for your Facebook and Instagram ads. There are plenty of exclusion rules, including:

  • Visits to a specific web page – when setting up a custom website audience, you can select the option to exclude certain people. You can apply up to five exclusion rules per audience. 
  • App activity – you can choose to exclude people from your custom audience based on app events. For example, you might include users who have opened your app or reached a certain level but exclude those who’ve already made an in-app purchase.
  • People who have interacted with products in your catalog: 

These exclusion rules can be very detailed and adjusted to the different campaign strategies you’ve set for clients, like:

  • Retargeting: Exclude people who have already purchased products to focus on those still considering a purchase.
  • Prospecting (Broad audience): Exclude past purchasers to ensure ads reach new potential customers.
  • Upselling: Exclude past purchasers of the advertised product set to focus on those who showed interest but haven’t bought yet.

Strategy #2: Use automation to optimize work for Facebook and Instagram clients

Automated Ads

Automated Ads make advertising on Facebook and Instagram much easier by taking the guesswork out of the equation. Just tell the system what’s important to your business, and it will suggest personalized ads to help you hit your goals. As your ads run, the system learns what works best and will offer suggestions to improve your results.

  • Multiple ad versions – you can create up to 6 versions of your ad. Based on the info from the client’s Page, the system will recommend the best call-to-action buttons, text, and creative elements. After a while, it will automatically show the version that performs the best.

  • Personalized audience suggestions – Advantage+ audience helps you create a custom audience for your ads based on your Page details. Over time, it adjusts to ensure you're reaching the most relevant people.

  • Budget recommendations – the system will suggest a budget that’s likely to deliver the best results. If you want to set your own budget, it’ll give you an estimate of what kind of results you can expect.

  • Timely notifications – you'll get helpful updates on how your ads are performing, with tips on how to make them even better. This might include advice like refreshing your image or letting you know when your ad starts generating leads or sales.

With these automated features, you can save time and get better results from your Facebook and Instagram ads.

Setting up automation rules

Automated rules help you manage your Facebook and Instagram ads by taking action on underperforming ads, so they don’t keep eating up your budget. With automation, you can set up rules that take care of tasks you would normally do manually, making your ad management much easier.

Here’s how it works:

When you create an automated rule, you’ll decide:

  • The criteria that triggers the rule

  • What action the rule takes on the ad

  • The specific campaign, ad set, or ad the rule will apply to


Automated rules are super helpful when you're managing multiple ads at once. Think about the tasks you do frequently in Ads Manager and automate them. For example:

  • Do you pause underperforming ads when they hit a certain metric?

  • Do you increase your budget after a certain number of people click on your ad?

  • Do you adjust your bid if your daily spend is too low?

  • Do you increase your budget based on return on ad spend (ROAS)?

  • Do you turn off a specific campaign every Friday?

By setting up these automated rules, you can keep your campaigns running smoothly without needing to keep a constant eye on them!
