Hi there,
Thanks for getting in touch. I had a look at your question about your Facebook Ads campaign and I'm happy to give you some of my initial thoughts and a bit of guidance based on my experience. It’s a really common situation to be in, so don't worry, you're not alone in facing this puzzle.
You've hit on something that trips up a lot of advertisers, both new and experienced. You get a campaign that's absolutely flying, like your Black Friday one, and the logical next step seems to be to just add your new promotion into that same successful ad set. But as you've found out, it rarely works out that way. It's frustrating, I know. Let's break down why this happens and what you should be doing instead to keep the momentum going.
We'll need to look at why new ads in old ad sets often fail...
Alright, so the first thing to get your head around is how the Facebook (or Meta, whatever we're calling it this week) algorythm works. When you have an ad set that's been running for a bit and has found its groove, the algorithm has gone through its 'learning phase'. It's figured out exactly who in your target audience is most likely to click, convert, or do whatever your objective is. It's optimised itself around that specific winning ad.
Think of it like this: the algorithm has a certain amount of budget to spend and its one and only job is to get you the best possible results for that money. It's identified your original Black Friday ad as the 'champion'. So, when you drop a new ad into the mix, the algorythm looks at it and says, "Well, I could show this new, unproven ad... or I could keep showing this other one that I know works really well and gets results." Naturally, it sticks with the safe bet. It'll continue to pump almost all the budget and impressions into the original ad because, from its perspective, that's the most efficient way to spend your money. The new ad barely gets a look-in and is essentially starved of the data and impressions it needs to even get started. It's not a fair fight from the get-go.
We see this constantly when we take on new clients and audit their accounts. They'll have ad sets with one ad getting 99% of the spend and four others just sitting there with a handful of impressions, and they can't figure out why those 'new ads aren't working'. It’s not that the ads are necessarilly bad; they just never got a proper chance to perform. This is a fundamental part of the platform that you have to work with, not against.
I'd say you should duplicate your ad set...
So, what's the solution? It's actually quite simple, but very effective. You need to duplicate the entire ad set that was working so well for you.
By duplicating the ad set, you're basically creating a clone. It copies all the successful settings you had: the targeting, the placements, the budget, the bidding strategy – all the stuff that made the Black Friday campaign a success. But crucially, it creates a fresh, new ad set that the algorithm treats as a seperate entity. It has no performance history.
Inside this new, duplicated ad set, you'll want to pause or delete the old Black Friday ad and then add your new promotional ad. Now, your new ad is the only one in the ad set. It will get 100% of the budget and the algorithm is forced to enter a new learning phase based entirely on this new creative. It has to go out and find the right people for this specific ad, giving it a fair shot at success. It's the cleanest way to test a new creative with a proven audience, and it's the standard practice we use for all our clients, from small eCommerce stores to large B2B software companies.
I remember one campaign where we worked with a women's apparel brand. Their summer collection ad was performing well. As the autumn collection was approaching, instead of adding the new ads to the summer ad set, we duplicated it, swapped the creative, and launched. The new campaign saw a 691% return because we kept the winning audience but gave the new creative its own space to work. It seems like a small admin step, but it makes all the difference to your results.
You probably should think about your campaign structure...
Taking a step back, this whole situation also highlights why having a solid campaign structure is so important for long-term success. Rather than just having one-off campaigns for things like Black Friday, it's often better to have an 'always-on' structure based on your marketing funnel. We usually break this down into three stages: Top of Funnel (ToFu), Middle of Funnel (MoFu), and Bottom of Funnel (BoFu).
-> Top of Funnel (ToFu): This is your prospecting campaign. The goal here is to reach new people who have never heard of you before. You'd use broad targeting, detailed interest targeting (e.g., targeting people who like competitor brands or related hobbies), or lookalike audiences based on your best customers. The ads here are about introducing your brand and grabbing attention.
-> Middle of Funnel (MoFu): This is for people who have shown some interest but aren't ready to buy yet. You'd retarget people who have visited your website, watched a certain percentage of your videos, or engaged with your Facebook or Instagram page. The ads here are about building trust and showing them more of what you offer.
-> Bottom of Funnel (BoFu): This is where the money is made. You're retargeting people who are very close to buying – they've added items to their cart, initiated checkout, or viewed specific products multiple times. Your Black Friday ad was likely a BoFu ad. The ads here are direct and designed to close the sale, often with an offer or a sense of urgency.
Here’s a simplified look at the kind of audiences you'd prioritise in each part of the funnel for an eCommerce business, for instance:
| Funnel Stage | Primary Audiences | Ad Objective |
|---|---|---|
| ToFu (Prospecting) | - Detailed Targeting (Interests, Behaviours) - Lookalike Audiences (of purchasers, high-value customers) |
Brand Awareness, Traffic, Lead Generation |
| MoFu (Consideration) | - All Website Visitors (last 30-90 days) - Video Viewers (50%+) - Social Media Engagers |
Traffic, Engagement, Product Views |
| BoFu (Conversion) | - Add to Cart (last 7-14 days) - Initiated Checkout (last 7-14 days) - Viewed Content/Product (last 7-14 days) |
Conversions, Catalogue Sales |
When you have a structure like this, running a new promotion becomes much easier. You can simply create new ads with your new offer and slot them into the apropriate campaigns (or duplicate the ad sets within them), rather than starting from scratch every time.
You'll need to watch out for ad fatigue...
One last but very important point. You mentioned wanting to use the same creative. While the ad creative itself was clearly a winner, you need to be careful about ad fatigue. This happens when your audience sees the exact same ad too many times and just starts ignoring it. Performance drops off a cliff, CPCs go up, and your ROAS plummets.
I remember a client, a home cleaning company, who had a fantastic ad that got them leads. After about six weeks, the cost per lead had crept up. The audience was just sick of seeing it. We created three new variations of the ad – same offer, but with different images and slightly different headlines. We duplicated the ad set, put the new ads in, and the cost per lead dropped straight back down.
Even if you're using the same core image or video, try to make small changes. Can you change the headline? Can you alter the first line of the ad copy? Can you put a different colour border on the image? These small tweaks can be enough to make the ad feel new and fresh to the viewer, resetting their attention and fighting off fatigue. Running the exact same visual for too long, even with a different offer, is a risky game. It's always better to be testing and refreshing your creative on a regular basis.
This is the main advice I have for you:
To pull all this together, here’s a clear, actionable plan I'd recomend you follow. This is the process we'd use ourselves in this situation and it balances getting quick results with setting you up for future success.
| Step | Action | Reasoning |
|---|---|---|
| 1. Duplicate | Go to your successful Black Friday campaign and duplicate the ad set. Give it a new, clear name (e.g., "[Promo Name] - [Audience] - [Date]"). | This preserves your winning audience and settings while creating a fresh environment for a new ad to be tested fairly. |
| 2. Swap Creative | In the newly created ad set, pause or delete the old Black Friday ad. Create your new ad with the new promotional copy and creative. | Ensures 100% of the budget goes to the new ad, forcing it through a proper learning phase. |
| 3. Launch & Monitor | Publish the new ad set. Be patient and let it run for at least 3-5 days to exit the learning phase before making any judgements on performance. | The algorithm needs time and data to optimise. Making changes too early can disrupt this process and lead to poor results. |
| 4. Mitigate Fatigue | Consider creating 1-2 extra variations of your new ad with slightly different headlines or images to test alongside the main one (each in their own duplicated ad set for a true test). | Proactively combats ad fatigue and helps you discover new winning creative elements for future campaigns. |
| 5. Plan Ahead | Think about building an always-on campaign structure (ToFu, MoFu, BoFu) to make managing future promotions and ongoing advertising much more efficient. | Moves you from a reactive, campaign-by-campaign approach to a strategic, funnel-based system that builds sustainable growth. |
Getting this right consistently can be tricky...
As you can see, what seems like a simple question opens up a lot of layers of strategy – from understanding the algorithm to structuring campaigns and managing creative fatigue. Getting these elements working together in harmony is what seperates campaigns that just 'do okay' from those that deliver transformative results, like the ones that generate a 1000% return on ad spend for our clients.
While you can definately implement the steps above yourself, consistently managing and optimising this process takes time, effort, and a deep well of experience.
