What is retargeting, and should a small business use it?

Retargeting is showing adverts to people who have already come across you — visited your site, watched your video, opened your profile. It reliably outperforms advertising to strangers, for the obvious reason. It is also the technique most often recommended to businesses that cannot actually use it yet, and that is the part worth getting straight.

Why it works so much better

Advertising to strangers has to do two jobs at once: introduce you, and persuade. Retargeting only has to do the second, because the introduction already happened.

It also catches people at the point most sales are lost — the ones who were interested, got distracted, and never came back. Most people who look at a service and do not enquire have not decided against you. They got interrupted. A reminder a few days later converts a share of them, and they were the warmest people you had.

The requirement nobody mentions first

You need an audience big enough for the platform to work with. Advertising systems will not deliver to a handful of people, and they enforce a minimum — typically in the hundreds.

So the honest arithmetic for a local business: if your website gets forty visitors a month, you cannot build a site-based retargeting audience in any useful timeframe. By the time you have enough people, the earliest ones have long since decided.

This is the reason retargeting advice frequently produces nothing for small businesses. The technique is sound. The traffic is not there. Be honest about which situation you are in before setting anything up.

The version that works without much traffic

Site-based retargeting is not the only kind, and for a small local business the other kind is usually better.

Engagement audiences are built from activity on the platform itself: people who watched a meaningful share of your video, who opened your profile, who interacted with a post, who messaged you. No website traffic required, and no tracking code.

For a business posting regular video, this builds far faster than site traffic does — a single video that reaches a few thousand people produces a usable audience where a year of website visits would not. If you are going to try retargeting at all, start here.

The consent part, briefly

Tracking visitors for advertising means storing information on their device, and in the UK that generally requires their consent — a real cookie banner where they can decline as easily as accept, with tracking held back until they agree.

Two practical consequences. First, you need a working consent mechanism before you install anything, not afterwards. Second, a meaningful share of visitors will decline, so your audience builds more slowly than the raw visitor count suggests. Plan for that rather than being surprised by it.

A plain summary, not legal advice. If you are setting up tracking, check the current requirements properly.

What to actually show them

The commonest mistake is showing the same advert again. They already saw it and did not act.

Better: answer the reason they hesitated. That is nearly always one of a few things — price, trust, timing, or not understanding what happens next. So:

• Proof, if the doubt was trust. A specific review, a photograph of real work.
• The price or the range, if the doubt was cost. Being straight about it converts more than avoiding it.
• What happens step by step, if the doubt was process. Frequently the real blocker.
• A reason to act now, if the doubt was timing — a genuine one, not invented urgency.

Do not be the advert that follows people around

Retargeting has a bad reputation entirely because of businesses that overdo it, and the fix is straightforward:

• Cap the frequency. A few times a week, not a few times an hour.
• Stop after a sensible window. Someone who looked at bathroom fitting seven weeks ago has decided.
• Exclude people who already bought. Advertising a service to a customer who has just paid for it reads as incompetence.
• Keep it unremarkable. An advert that draws attention to the fact it is following you is worse than no advert.

Is it worth it for you?

Probably yes if: you already advertise and it works reasonably; you get real website traffic; you post video that reaches a few thousand people; or your customers take weeks to decide and are worth a lot when they do.

Probably not yet if: your site gets a trickle of visitors; you do not advertise at all; your service is an emergency purchase decided in ten minutes; or your destination does not convert the traffic you already have. That last one matters most — retargeting sends warm people to the same page that is already losing them. Fix that first.

If you do it, do this much and no more

1. Get consent working before installing anything.
2. Install the tracking code for the one platform you actually advertise on. One, not four.
3. Build an engagement audience too, since it costs nothing and fills faster.
4. Wait until the audience is large enough to deliver. Check rather than assume.
5. Run one campaign that answers the likeliest hesitation, capped and time-limited.
6. Judge it on cost per enquiry against your cold campaigns. If it is not meaningfully better, something is wrong with the audience or the destination.

The bottom line

Retargeting works because the introduction already happened, but it needs an audience of hundreds, which most small business websites cannot supply. Build it from platform engagement instead of site visits, get consent working first, show something that answers the hesitation rather than repeating the advert, cap the frequency, and exclude people who already bought.
