So your e-commerce store is running, you're making some sales, but every time you try to push the ad spend up, your profitability tanks. Your return on ad spend (ROAS) gets worse, your cost per acquisition (CPA) skyrockets, and you're left wondering if scaling is just a myth for everyone but the big players. The truth is, it's not the algorithm holding you back. It's your strategy. Most founders blame their ads when the real problems are much deeper: a weak offer, fuzzy maths, and a leaky sales funnel. Forget looking for a magic bullet campaign setting. Let's fix the engine of your business so you can actually afford to scale, profitably.
Is your product the problem?
Before you spend another pound on ads, you need to have a brutally honest look at what you're selling. I see so many founders fall in love with their product, but they haven't stopped to ask if anyone else cares. The number one reason paid ad campaigns fail is a disconnect between the product and a real, urgent customer need. You're not just selling a product; you're selling a solution to a problem, a transformation, or the fulfillment of a desire.
Forget the vague demographic profiles like "women aged 25-40 who like fashion." That describes millions of people and helps you target precisely no one. You need to get obsessed with your customer's inner world. What is their specific, nagging pain point? Your Ideal Customer Profile (ICP) isn't a demographic; it's a problem state.
For example, if you sell sustainable clothing, your customer's problem isn't a lack of t-shirts. Their problem is the guilt they feel when looking at a wardrobe full of fast fashion. It's the desire to express their ethical values through what they wear. Your ads and your product descriptions need to speak to that feeling, not just the fabric composition. When you get this right, your conversion rates start to climb because your message finally resonates. You stop selling clothes and start selling a guilt-free conscience and a stylish identity.
Think about how you can package your products to solve a bigger problem. Don't just sell one dog collar. Sell a "New Puppy Starter Kit" with a collar, lead, bowl, and training treats. Don't just sell individual skincare items. Create a "30-Day Clear Skin Challenge" bundle. This approach turns a simple transaction into a solution-focused purchase, which immediately increases your average order value and makes your ad spend more efficient. I've seen this work for subscription boxes too. I remember working with a client selling dog treats for a subscription box, who was struggling with a high customer acquisition cost. We reframed the offer from "buy dog treats" to "give your dog a monthly surprise they'll love." It's a subtle shift, but it's everything.
Do you actually know your numbers?
The next question that separates struggling stores from scalable ones is this: "How high a Cost Per Acquisition (CPA) can I afford to acquire a great customer?" Most founders are obsessed with getting the lowest CPA possible, but that's the wrong goal. The real goal is to know how much you can profitably spend, which allows you to bid more aggressively and win the best customers from your competitors. The answer lies in your Customer Lifetime Value (LTV).
Calculating your LTV is not as complex as it sounds. You just need three numbers:
-> Average Revenue Per Account (ARPA): How much a customer spends on average, per month. If you're not a subscription, you can calculate this by taking your total revenue over a period (say, 12 months) and dividing it by the number of unique customers in that period, then dividing by 12.
-> Gross Margin %: Your profit margin after accounting for the cost of goods sold. If you sell a t-shirt for £30 and it costs you £10 to produce, your gross margin is 66.7%.
-> Monthly Churn Rate: The percentage of customers who don't make a repeat purchase each month.
Here's the simple maths:
LTV = (ARPA * Gross Margin %) / Monthly Churn Rate
Let's run an example for a hypothetical coffee subscription box:
-> ARPA = £25/month
-> Gross Margin = 70% (0.70)
-> Monthly Churn Rate = 10% (0.10)
LTV = (£25 * 0.70) / 0.10
LTV = £17.50 / 0.10 = £175
This means, on average, each customer you acquire is worth £175 in gross margin to your business over their lifetime. Now you have your North Star. A healthy LTV to Customer Acquisition Cost (CAC) ratio is 3:1. This means you can afford to spend up to £58 (£175 / 3) to acquire a single customer and still run a very profitable business.
Suddenly, that £40 CPA from Facebook ads doesn't look so scary, does it? It looks like a bargain. This single calculation frees you from the tyranny of cheap clicks and allows you to make strategic decisions. It helps you understand why sometimes high ad costs are not the real enemy; a low LTV is. Once you know you can afford to pay £58 for a customer, you can outbid competitors who are still trying to get customers for a fiver. This is how you scale.
Are your ads speaking to anyone?
If your offer is solid and you know your numbers, the next failure point is almost always the ad creative. Most e-commerce ads are a boring catalogue of features. "100% Organic Cotton." "Handmade in the UK." "Fast Shipping." Nobody cares. People buy on emotion and justify with logic later. Your ad's only job is to create an emotional spark.
To do this, you need to stop talking about yourself and start talking about them. Two frameworks I use constantly with my clients are Problem-Agitate-Solve (PAS) and Before-After-Bridge (BAB).
Problem-Agitate-Solve (PAS):
This is for products that solve a clear pain point. You state the problem, poke the bruise to make it feel more urgent, and then present your product as the perfect solution.
Let's take a bespoke jewelry brand. Instead of "Shop our new collection," try this:
-> Problem: Tired of wearing the same generic jewelry as everyone else?
-> Agitate: You want your style to feel unique and personal, but high-street accessories all look the same, leaving you feeling uninspired.
-> Solve: Our handcrafted pieces are made in limited runs, so you can express your individual style with jewelry that's as unique as you are.
This approach is powerful because it starts with the customer's frustration, not your product. It makes them feel understood. When you do this correctly, you will get people to your site, but if they still don't buy, it could be a sign that you need to work on your post-click experience. In fact, one of the most common issues I see is brands having a high click-through rate but no sales, which points directly to a disconnect between the ad's promise and the landing page's reality.
Before-After-Bridge (BAB):
This is great for aspirational products that promise a transformation.
Let's use a fitness eBook as an example:
-> Before: You feel sluggish, unmotivated, and uncomfortable in your own clothes.
-> After: Imagine waking up with energy, feeling confident and strong, and loving the way you look.
-> Bridge: Our 12-week fitness plan is the step-by-step bridge to get you there.
Notice how the product is the "bridge." It's the vehicle for their transformation. This is far more compelling than listing the number of pages or recipes in the book. It sells the destination, not the plane ticket. I remember using this exact framework for a client's fitness eBook launch, and it worked wonders.
And for god's sake, stop using overly polished, stock-style photos. People are tired of perfect. They crave authenticity. User-generated content (UGC) – real customers using and loving your product – is gold. It acts as social proof and looks native in their social media feeds, making it far more trustworthy and effective than a glossy studio shot.
Why are people leaving your store with full baskets?
So your ads are working. You've got a great offer, your messaging is on point, and people are clicking. They're even adding items to their cart. But then... nothing. The sales don't come through. This is probably the most frustrating stage for any e-commerce founder, and it's where you need to become a detective and analyse your funnel.
Where are people dropping off? Your website analytics hold all the clues.
-> High Traffic, Low 'Add to Carts': If people land on your product page but don't add anything to their basket, the problem is likely on that page. Is your pricing clear? Are the product photos high-quality and showing the product from multiple angles (ideally on a person or in context)? Are your product descriptions compelling, reiterating the benefits you promised in the ad? Is there a clear, unmissable 'Add to Cart' button? Often, the reason for this drop-off is that the ad promises one thing and the page delivers another. The scent is lost, and the customer gets confused and leaves.
-> High 'Add to Carts', Low 'Initiate Checkouts': This is a classic. People love your product enough to add it to their basket, but something stops them from taking the next step. The culprit is almost always a surprise cost, and 99% of the time, that's shipping. Be upfront about your shipping costs. A high, unexpected shipping fee at checkout is the number one cause of cart abandonment. Another reason could be a forced account creation. Let people check out as a guest. Removing that friction is huge.
-> High 'Initiate Checkouts', Low 'Purchases': They've started the checkout process but bailed at the last second. This is a five-alarm fire. Your checkout process is likely too long or confusing. How many fields are you asking them to fill out? Can it be simplified? Do you have trust signals on the page? These include security badges (Visa, Mastercard, Shopify Secure), customer reviews or testimonials, and clear return policies. At this final stage, the customer is looking for any reason not to go through with it. Don't give them one. This exact scenario, with lots of cart additions but few final sales, is something we troubleshoot all the time.
For some e-commerce niches, where purchases are more considered, this problem is even more pronounced. I've seen clients with high add-to-carts but low conversion rates, and the fix often involves adding more trust signals, clearer sizing guides, and better retargeting ads to bring those hesitant buyers back.
How to structure your campaigns for growth, not just clicks
Okay, let's get into the nitty-gritty of your ad accounts. If you want to scale, you can't just throw a bunch of audiences into one campaign and hope for the best. You need a structure that mirrors your customer's journey. I split this into three stages: Top of Funnel (ToFu), Middle of Funnel (MoFu), and Bottom of Funnel (BoFu).
This structure should be built out in separate, long-running campaigns for each stage. This lets you control your budget allocation and give the ad platforms clear signals about what you want to achieve.
Top of Funnel (ToFu) - Prospecting:
This is about finding new people who have never heard of you. Your goal here is cold acquisition. The audiences you'll test here are:
-> Detailed Targeting: Interests, behaviours, and demographics. This is your starting point. Get really specific. If you sell high-end gym apparel, don't just target "Fitness." Target followers of specific athletes, readers of niche fitness magazines, or customers of complementary (but not competing) brands. People often make the mistake of going too broad, which is a common reason why their interest targeting hurts sales rather than helping.
-> Lookalike Audiences: Once you have data, this is your most powerful tool. Create lookalikes based on your best customers, not just all your website visitors. Start with a lookalike of your 'Purchasers' list. Then work your way up the funnel: 'Add to Cart', 'Initiate Checkout', etc. A 1% lookalike of your top 10% of customers by LTV is often a goldmine.
-> Broad Targeting: This means targeting just by age, gender, and location, with no interest or lookalike layers. This can work incredibly well once your Meta Pixel has thousands of conversion events. You're trusting the algorithm to find your customers for you, but you need to give it enough data to learn first.
Middle of Funnel (MoFu) - Nurturing:
These people have shown some interest but aren't ready to buy yet. Your job is to stay top of mind and build trust. Here, you'll retarget:
-> All website visitors in the last 30-90 days (excluding purchasers).
-> People who have engaged with your Facebook or Instagram page.
-> People who have watched a certain percentage (e.g., 50%) of your video ads.
Your ad creative here should be different. Show them testimonials, user-generated content, or highlight a different benefit of your product. Don't just show them the same ad they saw the first time.
Bottom of Funnel (BoFu) - Closing:
This is your lowest-hanging fruit. These people are on the verge of buying. Your only goal is to get them over the line. Here, you'll retarget:
-> 'Add to Cart' in the last 7-14 days (excluding purchasers).
-> 'Initiate Checkout' in the last 3-7 days (excluding purchasers).
Your ads here can be more direct. Remind them what they left behind. Offer a small discount or free shipping to seal the deal. Use Dynamic Product Ads (DPAs) to show them the exact products they viewed or added to their cart. This is your highest ROAS campaign, so make sure it's always running.
Having a clear structure like this is non-negotiable for scaling. I've worked with brands that were a mess of overlapping campaigns and ad sets. By implementing a simple ToFu/MoFu/BoFu system, we were able to bring clarity and profitability back. It's a fundamental step for any e-commerce niche.
Which ad platform should you use?
Don't be a magpie, chasing every shiny new platform. For 95% of e-commerce businesses, your focus should be on mastering two platforms: Meta (Facebook & Instagram) and Google.
Meta (Facebook & Instagram): The Demand Generation Engine
This is where you go to create demand for your product. People are not on Instagram to shop; they're there to be entertained and discover new things. Your job is to interrupt their scroll with something so compelling they can't help but click. It's the king for visual products, lifestyle brands, and anything that benefits from impulse buys.
A huge mistake I see is founders running 'Brand Awareness' or 'Reach' campaigns. You are literally paying Facebook to find the people least likely to ever buy from you, because their attention is cheap. Don't do it. Always, always, always optimise for conversions (Purchases). You're telling the algorithm "Go find me people who look like my existing customers and are likely to buy something." Awareness is a byproduct of sales, not the other way around.
Google Ads: The Demand Capture Engine
This is where you go when people are already looking for what you sell. The intent is sky-high. If someone types "buy vegan leather work bag" into Google, you want your ad to be the first thing they see.
For e-commerce, your two main campaign types will be:
-> Search Ads: Target high-intent keywords that include words like 'buy', 'shop', 'sale', 'for sale', or your specific product names and brand name.
-> Performance Max (PMax): This is Google's all-in-one campaign type that runs across YouTube, Display, Search, Discover, Gmail, and Maps. You feed it your product feed, creative assets (images, videos, copy), and audience signals (like your customer lists), and it does the rest. It can be incredibly powerful but also a bit of a black box. For new stores, it's often best to start with Standard Shopping before moving to PMax. Getting the bidding strategy right on a new campaign is crucial to avoid burning cash.
Other Platforms (Pinterest, TikTok, etc.):
These are great for expansion once you've maxed out Meta and Google. Pinterest is fantastic for visual niches like home decor, weddings, fashion, and food. We've seen a 691% return for a women's apparel client by combining Meta with Pinterest Ads. TikTok is powerful for trend-driven products and reaching a younger audience, but the creative has to be native to the platform (i.e., not a polished ad).
What to do when you hit the scaling wall
Inevitably, you'll hit a plateau. You've optimised your funnel, your ads are running smoothly, but you just can't seem to increase your spend without your ROAS falling off a cliff. This is normal. It means you've likely saturated your core audience.
Hitting a wall doesn't mean the game is over. It means it's time to get more sophisticated. I've seen this happen with an e-commerce client who hit a plateau; sales were great but just wouldn't grow beyond a certain point. Here’s what we did, and what you should do too:
1. Go Back to Your Funnel:
-> Improve Conversion Rate (CRO): A 0.5% increase in your website's conversion rate can be the difference between a profitable and unprofitable campaign at scale. A/B test your product pages, your headlines, your call-to-action buttons. Can you improve your site speed? Every second counts.
-> Increase Lifetime Value (LTV): This is the real secret to scaling. If your customers are worth more, you can spend more to acquire them. How can you increase LTV? Introduce a subscription model. Create product bundles. Implement a post-purchase email sequence to encourage repeat buys. Add a loyalty program. This is the most powerful lever you have.
2. Go Deeper on Ads:
-> Relentless Creative Testing: You should have a system for constantly testing new ad creative. What worked 3 months ago is probably fatigued by now. Test new angles, new hooks, new formats (video, carousel, static image), and especially more user-generated content.
-> Deeper Audience Expansion: Go back to your ToFu campaign. Have you tested every possible lookalike audience? Have you explored new interest categories? Have you tried layering interests to create more niche audiences? There are always more pockets of customers to find.
3. Go Wider on Platforms & Markets:
-> Expand to a New Platform: If you've mastered Meta, it might be time to build a proper presence on Google Shopping. Or if you're in a visual niche, dedicate a real budget to Pinterest.
-> Expand Geographically: Are you only selling in the UK? Test the US, Canada, Australia, and English-speaking European countries. Run these as separate campaigns, as costs and performance will vary wildly. Start with a small test budget and see what sticks.
Scaling isn't a single action; it's a continuous process of improvement across your entire business. It's about building a robust system that can handle more volume profitably.
I know this is a lot to take in. Scaling paid advertising for e-commerce is complex, with a lot of moving parts. Getting it wrong can be incredibly expensive, not just in wasted ad spend but in months of lost growth. Getting it right, however, can transform your business.
I've detailed my main recommendations for you in the table below. This is the checklist I would run through for any e-commerce founder looking to scale.
| Area of Focus | Actionable Recommendation | Why It Matters |
|---|---|---|
| 1. Your Offer | Define your ICP by their pain point or desire, not just demographics. Package products into solution-focused bundles or kits. | A strong, relevant offer is the foundation. Without it, the best ads in the world will fail. Increases Average Order Value (AOV). |
| 2. Your Numbers | Calculate your Customer Lifetime Value (LTV) and determine your maximum allowable Customer Acquisition Cost (CAC) based on a 3:1 LTV:CAC ratio. | This frees you from chasing cheap clicks and allows you to bid competitively and strategically for high-value customers. |
| 3. Ad Creative | Use frameworks like Problem-Agitate-Solve (PAS) or Before-After-Bridge (BAB). Prioritise authentic User-Generated Content (UGC) over polished studio shots. | Creates an emotional connection that stops the scroll and drives action. Builds trust and social proof far more effectively than brand-led creative. |
| 4. Funnel Diagnostics | Analyse drop-off points: -> No Add-to-Carts? Fix product page (copy, images, price). -> No Checkouts? Fix shipping costs/surprises. -> No Purchases? Fix checkout friction/trust. |
Your website is leaking money. Plugging these holes is the cheapest and fastest way to increase your overall ROAS. |
| 5. Ad Account Structure | Implement a ToFu, MoFu, BoFu campaign structure. Separate prospecting (cold) from retargeting (warm/hot) audiences. | Provides control, clarity, and allows you to allocate budget efficiently across the entire customer journey, which is essential for scaling. |
| 6. Scaling Levers | When you hit a plateau, focus on improving LTV (subscriptions, bundles), relentless creative testing, and expanding to new platforms/markets. | Growth at scale doesn't come from doing more of the same. It comes from systematically improving your core business metrics and expanding your reach. |
