The Biggest Retargeting Mistake (And Why Your Remarketing Isn’t Converting)

Remarketing campaigns almost always win on ROAS.

That is not a guess. When you advertise to people who already visited your site, you are talking to a warm audience. They know your brand. They were interested enough to click once already.

So the return looks great, and everyone gets excited.

But there is one massive mistake I see agencies and business owners make with retargeting. It quietly costs clients thousands of Rands a month.

And it is the kind of mistake that hides, because the ROAS still looks okay on the surface.

Here is what is going on, why it hides, and what to fix before you waste another cent.

What is retargeting (and why does it usually have the best ROAS)?

Retargeting means showing ads to people who already visited your website but did not buy.

A small piece of code, a pixel, drops a cookie on their browser when they land on your site. Later, while they scroll Instagram or read the news, your ad finds them again.

Here is why it even exists. Only about 2% of people buy on their first visit to an online store, according to CRO firm Invesp. The other 98% leave. Retargeting is how you try to win some of them back.

You will also hear the word remarketing. Same idea. Retargeting means paid ads chasing past visitors. Remarketing usually means email or SMS doing the same job. Do not stress about which word is which.

Why does it print such good numbers? Because warm beats cold. Every time.

A stranger seeing your brand for the first time needs convincing. A past visitor already crossed that line. Retargeted visitors convert up to 150% better than cold ones. That is not an opinion. DemandSage tracked it in 2025.

So far so good. This is exactly why retargeting deserves a spot in your budget. The problem is what most people are retargeting people back to.

The biggest retargeting mistake: chasing people back to a broken page

Here is the mistake. You retarget visitors straight back to the same page that already failed to sell them, and you change nothing about that page.

Think about what you are actually doing.

Someone landed on your product page. They looked. They did not buy. Something put them off.

Now you pay money to drag them back to that identical page. The same weak offer. The same confusing layout. The same missing reviews. The same slow load.

Why would the outcome be different the second time?

This is the part people miss. Retargeting does not fix a conversion problem. It amplifies whatever you already have.

If your page converts cold traffic at 1%, retargeting just buys you more expensive 1%. You are pouring fuel into an engine with a hole in it.

I say this all the time. Do not scale a leaky funnel. Retargeting a broken store is the purest form of that mistake, because you are literally paying twice to send the same person to the same dead end.

And it gets worse. Most stores leak badly. The Baymard Institute, which has studied this for over a decade, puts the average online shopping cart abandonment rate at around 70%, averaged across dozens of studies. So seven in ten people who add to cart still walk away. Retargeting them back to the same broken checkout just reminds them why they left.

Why did they leave the first time?

Before you spend a cent retargeting, answer one question. Why did they not buy?

Because the answer to that is the thing you need to fix. Not the ad. The reason.

Across 500+ SA stores, it is almost always one of these five.

The offer was weak. The deal did not feel worth it. No bonus, no guarantee, no reason to act now. Just "buy my product" at full price. We dig into this in understanding offers.

There was no trust. No reviews, no clear returns policy, no proper About page, no payment logos. A first-time SA shopper will not hand over their card to a site that feels sketchy.

The page was slow or confusing. It loaded like a dial-up modem, or the buyer could not figure out the next step. Confused people do not buy. They leave.

The checkout was a mission. Forced account creation, surprise delivery costs at the last step, too many form fields. Every extra click bleeds buyers.

The price felt wrong for the value shown. Not too high in Rands, just too high for how little value the page communicated. That is a value problem, not a price problem.

Notice none of those get fixed by a retargeting ad. They get fixed on the page.

That is the whole point of the original lesson. Retargeting visitors without fixing this first is the mistake. "This" is the reason they bounced.

Retargeting a broken funnel vs a fixed one

Same traffic, same ad budget. The only difference is whether you fixed the page first. Look at what that does.

What happens	Retargeting a broken funnel	Retargeting a fixed funnel
The page they land on	Same one that failed first time	Stronger offer, proof, faster checkout
Conversion rate	Stuck at ~1%	Lifted to 2.5%+
What your ad spend buys	More expensive 1%	More of a rate that actually sells
Cost per sale	High and climbing	Lower, because more clicks convert
How the ad feels to the buyer	"Why is this following me?"	"Oh good, the thing I wanted"
Result	Burns budget, looks "okay"	Compounds your best traffic

The fixed funnel wins on every single row. And you did not touch the ad budget. You fixed the page the ad points at.

Fix this before you spend another Rand on retargeting

Here is the checklist we run before we are happy to scale retargeting for any store.

1. Sharpen the offer. Give people a real reason to buy now. A bonus, a bundle, a guarantee, free delivery over a certain spend. Make the deal feel fat. A strong offer beats a clever ad every time.

2. Stack the proof. Reviews on the product page. Real photos. A clear returns policy. Payment and security logos. Answer the quiet question "can I trust these people with my card?" before they ask it.

3. Speed up the page. A slow store kills sales faster than load-shedding kills a braai. Compress images, cut the junk apps, test it on a normal phone on mobile data, not your office wifi.

4. Clean up the checkout. Allow guest checkout. Show delivery costs early. Cut the form fields to the bare minimum. Every step you remove is money saved. We cover this in detail in the biggest eCommerce conversion rate mistake.

5. Match the page to the promise. If the ad sold a 20% off winter sale, the page must scream 20% off winter sale. Mismatched ad and page is a silent killer. More on this in why your online store conversion rate is dropping.

Do those five and your conversion rate climbs. And here is the magic. Every visitor now converts better, cold and warm. Your retargeting suddenly works harder on the same spend, because it is pointing at a page that actually sells.

Fix the engine first. Then add fuel. There is a full playbook for this in how to optimise your online store for profit.

Now retarget the smart way

Once the page converts, retargeting becomes a money printer instead of a money pit. But there are still ways to mess it up. Avoid these.

Do not show everyone the same ad. Someone who bounced off your homepage in eight seconds is not the same as someone who spent four minutes on a product page. Split your audiences by how warm they are, and speak to each one differently.

Stop retargeting people who already bought. Showing a "buy now" ad for the exact thing someone purchased last week is wasted money and it annoys them. Exclude recent buyers from your sales ads. Use a separate campaign to upsell them instead.

Cap your frequency. Hammering people with the same ad over and over actually hurts how they see your brand. There is a line between a helpful reminder and "why is this stalking me?". Do not cross it.

Give them a fresh angle. Do not just repeat the first ad. Show a review, answer an objection, add a small incentive, show the product in use. Give a new reason, not the same nag.

Use dynamic product ads. Show people the exact item they looked at or left in their cart, not a generic brand banner. This is where the best ecommerce retargeting numbers come from.

This is the part most agencies jump straight to, while skipping the page fix entirely. Smart targeting on a broken funnel is still a broken funnel. Get the order right or none of it works.

A worked example in Rands

Here is what this looks like in Rands.

Say your store gets 10,000 visitors a month. It converts at 1%. Your average order is R750.

That is 100 orders. R75,000 in revenue.

Now you decide to retarget the 9,900 who did not buy. You spend R20,000 on ads to bring them back. But the page is unchanged, so they convert at the same 1%. You claw back a handful of sales at a brutal cost per sale, and the ROAS quietly drags your account down.

Now run the other play. Before spending a cent on retargeting, you fix the offer, the proof, the speed, and the checkout. Conversion climbs to 2.5%.

Those same 10,000 visitors now do 250 orders. R187,500. From the exact same traffic, before you have retargeted anyone.

Then you switch retargeting on. It now runs against a 2.5% page instead of a 1% page. Same R20,000 spend, but every Rand works more than twice as hard.

Same store. Same month. Same ad budget. The only change was the order you did things in. Fix first, retarget second.

That gap, R75,000 versus R187,500 plus a far healthier retargeting return, is the money this mistake quietly costs. Month after month.

How V8 Media fixes this for SA stores

We are a performance agency. If the campaign does not grow the business, we have a problem. So we never just switch on retargeting and hope.

First we look at the funnel. Where are people leaking? Is it the offer, the trust, the speed, or the checkout? We are an ecommerce growth agency, so this is the first thing we audit on every store.

We fix the page so it actually converts. Then we build the retargeting properly.

A sharp retargeting ad on Meta catches your warm audience while they scroll. The same audience on Google Ads catches them the moment they search again. Both pointing at a page that sells, not one that leaks.

That is the whole difference. Most brands bolt retargeting onto a broken store and wonder why the magic numbers never show up. We fix the store first, so the magic numbers are real.

Five hundred businesses. R2 billion in sales tracked. The pattern never changes. The winners fix the funnel, then scale the warm traffic. The stuck ones keep paying to send people back to the same dead end.
