Why Paid Ads Are the Wrong Play for a Multi-Brand Fashion Store

Last year we audited a multi-brand fashion retailer. 4 physical stores, over 50 brands on the floor, big names like Levi's, Tommy and Lacoste, plus niche French-Danish, Dutch and Italian labels nobody within 50 km has ever heard of. The eCom side was doing 200k€ a year at best, roughly 10% of in-store revenue. The owner wanted to push it to 300, ideally 500k. And his first instinct was, of course, to throw more money at ads.

I told him not to. Or at least, not the way he pictured it. Let me explain why, because it's counterintuitive and most agencies will sell you the exact opposite.

On a multi-brand store, you're fighting your own suppliers

The thing nobody tells you is that running paid on a multi-brand store is like going into battle with a knife against guys carrying bazookas.

When you sell a pair of Levi's jeans on your site, Levi's is also advertising that same pair. And Levi's has 2 to 3 times more acquisition budget than you on that exact product. So does Zalando. So do the other resellers. You're bidding on the exact same products, with the exact same listing, but with margins 2 to 3 times thinner than a brand selling direct. Because a direct brand pockets the full margin. You buy wholesale and resell. Your margin melts fast.

So the math is simple. Huge and constantly rising acquisition costs, thin margins. You can run that for six months, but in the end you're paying to exist on auctions you'll always lose to the very brands you distribute. Even the best paid agency won't change that. The problem is baked into your distribution model.

I've said it to our clients more than once, and I'll repeat it here: an eCommerce audit should always start with your P&L, not your campaigns. If you look at your real margins on a multi-brand store first, you immediately understand why blanket paid is a dead end.

Cannibalization, the problem he felt without naming it

There's a second problem, even nastier. And this one, the owner had sensed on his own without knowing what to call it.

His online customers were 90% local. People who know the store, who scout the site before heading in. Or who've already walked through the door three times that year. In short, customers who would have come anyway.

When you put an ad in front of that customer, you nudge them to buy online a piece they would have bought in-store. Except online, you eat the shipping costs and the acquisition cost. In-store, you didn't eat any of that. So you paid to sell, at a lower margin, a sale you had already won.

It's the exact same mechanism as when you pay for an ad to re-buy a customer you'd already sold to. You burn budget on a sale that would have landed without you. On a local multi-brand store, this isn't an edge case, it's the default setting.

The owner told me "I feel like my ads are stealing sales from my stores." He was right. His gut beat his old provider's dashboard.

Convert better instead of chasing more traffic

So the real question becomes: how do I convert the people who are already here better? We'll worry about traffic volume later.

His store wasn't short on traffic. These were qualified visitors, locals who know the store. The problem was the site. Mediocre product pages, a laggy checkout flow, no reassurance, no clear logic between in-store stock and online stock. People showed up, looked around, and ended up coming into the store, or worse, left for somewhere else.

In eCommerce, you don't buy a product, you buy the photo. And traffic on your site is like foot traffic in your store. If people walk in and walk out without buying, you don't fix that by sticking a bouncer at the door to let more people in. You fix it by redoing the inside of the store.

That's the whole point of not killing the energy your visitors arrive with on your site. You can have the best traffic in the world, but if the site kills the intent to buy, you've gained nothing.

So our recommendation was clear. Before talking about a single extra euro of ad spend, you build a machine that converts. You rebuild the product pages, you unify in-store and online stock, you clean up the flow, you work on conversion. And that changes everything on the cost side.

When your machine runs better, all your acquisition costs drop mechanically. A site converting at 2.5% instead of 1.2% means a cost per sale cut in half, with the exact same traffic. So if one day you genuinely want to scale with ads, you're starting from a healthy base. You spend to amplify a mechanism that works, not to paper over a leaky site.

We have a very similar comparable. A gift concept store, several retail locations, 95% of its revenue in retail, unified stock on the site, same thin margins, same local customer base. The logic is identical. You don't win by buying traffic, you win by making every visitor count.

The only paid that makes sense: local, niche drive-to-store

I don't want to make you think paid should be banned 100%. There's one case, just one, where it holds up on a multi-brand store of this type.

Local drive-to-store. Small budgets, tight geo-targeting. And above all, you don't advertise the big brands. You advertise the niche brands you're the only reseller of within a 50 km radius. The French-Danish, Dutch and Italian labels nobody else carries near you.

It works because you have no competitor on the auction. The brand itself often doesn't advertise in France, and nobody else sells them nearby. You're alone. So your acquisition cost is low and you drive people into the store for pieces they won't find anywhere else locally.

In practice, two formats:

• Meta with a dynamic catalog. You load your product feed and Meta surfaces the pieces most likely to appeal to each user on its own. Broad targeting, you let the algo work on your area.
• Google Shopping on those same niche brands, with a tight budget around 15 to 20€ a day, like the store was already doing historically.

The rest, blanket paid on the big brands, drop it. It's not profitable and it never will be on this model.

And if you want to dig into how your acquisition strategy should evolve as you grow, you'll see that paid at scale has its place at some point, just not this one. Not when your eCom is 10% of your revenue and your margins are crushed by your own distribution model.

What to remember if this is you

If you run a multi-brand store and you want to grow your eCom, don't start with ads. Start with your P&L and your site.

So: look at your margins by brand before thinking about ads. On the big ones, you're too weak to compete. And if your online customers are local, your ads are almost certainly eating into your stores. The rest of your budget goes into conversion, on product pages, the flow, unified stock. Paid, you keep for a single use, drive-to-store on your niche brands with local exclusivity.

The store I've been talking about from the start didn't raise its ad budget. It rebuilt its site. We're aiming for 350-400k by year end, and so far the curve is holding. Without touching the Meta budget.
