Your meta ads look great, so why is your growth flat?
The hidden new vs. returning ratio problem killing your results
Hi there,
It’s easy to feel like your Meta ads are performing just fine… until you dig a little deeper.
On-platform, the numbers look great. But once you cross-check with tools like Triple Whale, Polar, or even a simple new vs. returning customer breakdown in Shopify, the truth hits:
You’re spending a lot… but growing very little.
More often than not, that’s because most of that ad spend is going toward existing customers. Not net-new ones.
And while there’s nothing wrong with squeezing a few extra purchases from loyal fans, if your goal is incremental growth, your budget should be working harder to bring in new people.
So in a world where we’re told to “trust the algorithm,” how do you actually get Meta to find fresh faces, without micromanaging every detail?
Here are four common pitfalls I see, and how to fix them:
1. Static overload
Static ads are easy to produce, but they tend to resonate most with people who already know your brand. That means Meta often serves them to existing customers.
Tip: Compare your static vs video creatives. How does each perform for new vs. returning customers?
While it varies by brand, video tends to push Meta to explore new audiences and creative angles. If your goal is new acquisition, prioritise video.
2. Endless optimisations on the same ad
It’s tempting to make 50 tiny tweaks to your best ad, but eventually, Meta narrows in and serves it to the exact same audience over and over.
Tip: Think bigger. Try new offers, bold hooks, and different sub-audiences. Stop tweaking and start disrupting what Meta thinks it knows about your “best” customers.
3. Weak or outdated exclusions
Exclusion lists are often a one-and-done setup. But if you’re only using one source—or relying on stale lists that aren’t automatically updated—you’ll miss a lot of existing customers who should be filtered out.
Tip: Layer multiple exclusion sources (such as pixel data and email lists) and ensure they update automatically.
This is especially important for high-frequency purchase products, where Meta is extra tempted to go for the easy win.
4. Conversion window isn’t helping
Meta’s default windows (especially view-through) can skew results in favour of easier, already-engaged users.
Tip: Test click-only conversion windows. This forces Meta to optimise for more intentional buyers. Expect a short-term dip, but in the long run, it often leads to stronger acquisition performance.
What causes ad fatigue?
It’s easy to assume the problem is just not having enough creatives. But the bigger issue is often that the creatives you do have are too similar week after week.
Remember, on Meta, your creative is your targeting. If you keep optimising around the same look, feel, or message, you’ll end up hitting the same pockets of the same audience over and over.
Here are a few other common culprits:
Targeting a smaller niche or country for an extended period of time
Overreliance on static ads, which often skew to a bottom-of-funnel audience
Running the same offer for too long
Spending too little time or energy brainstorming genuinely new ideas
Lacking internal resources to produce creative at scale
How to solve creative fatigue
Step one is diagnosing the cause. If the issue is a limited market size, no amount of new creatives will fix it. That’s a bigger strategic question: do you expand into new geographies or explore new customer segments?
For most brands, though, it is a creative problem. Here’s how I approach it:
1. Test the impact of fatigue
Temporarily reduce the budget on the campaigns you suspect are fatigued and measure the incremental impact.
You’ll lose some conversions, but if the cost per extra conversion shoots far above your CAC, that’s a clear sign fatigue is the culprit.
2. Have the hard conversations internally
Pausing or rotating creatives can cause short-term dips.
Make sure the team is aligned that you’re optimising for long-term profitability, not just hitting a growth target this week.
3. Rebuild your creative backlog
Don’t just recycle what’s worked before. Experiment with new formats (video, carousel, UGC, story-first), new angles, and a wider range of hooks.
4. Bring in fresh eyes
Whether it’s a freelancer, another team member, or even your customers, fresh perspectives can spark ideas your core team might never consider.
Creative fatigue isn’t solved by cranking out more of the same.
It’s solved by rethinking how you approach creative in the first place
Recommendation
In every edition of Growth Waves, I also share a related resource to check out related to the week's topic.
If your Meta Ads performance suddenly dipped, you’re not alone.
What we haven’t talked about yet is that Meta just rolled out one of its biggest algorithm updates ever — Andromeda.
DTC Daily sifted through hundreds of posts and distilled what the top experts are actually saying into one clear, practical playbook that explains:
Why old “winning ads” die faster than ever
How Meta reads your creative for signals
The 4-Source System to generate infinite new ad ideas
I recommend subscribing to DTC Daily, too: they share 3 bite-sized, curated strategies in each issue that you can implement today.
The first step? Check your new vs. returning ratio. A bit of overlap is normal (and often helpful), but if you're seeing a majority of your spend go to repeat customers, it’s time to recalibrate.
Get Meta working as hard as you do.
Till next week,
