Retargeting: bringing back people who left without enquiring
Most people leave a site without sending a request. That is normal: they are comparing, thinking, or got distracted. Retargeting is a way to come back to those who already showed interest, and it is usually the cheapest advertising you have.
This is advertising to people who already visited your site, and it is usually the cheapest of all: conversion in these audiences is several times higher. A typical return is 10–20% of all requests on 5–10% of the budget. The essentials are capping frequency and audience lifetime, or the advertising turns into stalking and works against you.

Why it is cheaper than ordinary advertising
You pay to reach people who have already been on your site. They know who you are, and some of them are still choosing. Conversion in these audiences is usually several times higher, which means the cost per request is noticeably lower.
The audience is capped by the size of your traffic, though — retargeting does not replace acquisition, it sits on top of it.
Retargeting is worth launching once enough people visit the site: with ten visitors a day there is nobody to build an audience from.
Which audiences to build
| Audience | What to show | Priority |
|---|---|---|
| Visited a service page | That service, with price and benefit | High |
| Started the form but did not send it | A reminder and help | Highest |
| Added an item to the cart | The item and delivery terms | Highest |
| Spent over a minute on the site | A general offer | Medium |
| Already bought | Related services | Medium |
| Arrived and left immediately | Usually exclude | Low |
Splitting by audience matters more than it seems. Showing the same message to someone who abandoned a cart and to someone who wandered onto the homepage wastes budget and irritates people.
What to show
- Remove the objection. The person left because they had doubts. Show a guarantee, a review, an answer to a common question.
- A specific reminder. The same service or the same product, not an abstract company banner.
- An extra argument. Instalments, a free visit, a no-obligation consultation.
- A time limit — if it is real. A perpetual «offer ends this week» erodes trust.
How not to become intrusive
Retargeting turns into stalking easily: someone views one product and sees it everywhere for a month. That is irritating and works against the brand.
- Cap the frequency — a few times a day is more than enough.
- Cap the audience lifetime: 7–30 days depending on how long the decision takes.
- Exclude people who already sent a request or bought.
- Rotate creatives: the same image for a month straight wears people out.
- Do not chase people who spent five seconds on the site.
The retargeting window should match the real decision cycle. For food delivery that is days, for choosing a dental clinic it is weeks, for buying equipment it is months.
What needs to be set up technically
- The ad platform's tag or pixel on every page of the site.
- Separate events for the actions that matter: viewing a service, starting the form, sending a request.
- Audiences built on those events, not just on «all visitors».
- Exclusion audiences — the people you should not show to.
- Cookie consent, where your country's law requires it.
What to expect from the numbers
Retargeting usually brings fewer requests in absolute terms but at a noticeably lower cost. A typical picture: 10–20% of all requests on 5–10% of the budget. The exact figures depend on traffic volume and the length of the decision cycle.
The scenarios that work best
- Abandoned cart or formThe most productive scenario: the person was one step from acting. Remind them within the first day.
- Viewed a service but did not enquireShow the same service with an extra argument: guarantee, instalments, a free consultation.
- Visited long ago and never returnedRemind them a month or two later with a new offer, not the same one.
- Already a clientRelated services and repeat purchases — usually the most profitable audience of all.
Limitations worth knowing
- Some users block tracking — the audience will be smaller than your visitor count.
- Cookie consent is required where the law demands it.
- Audiences have a minimum size: with low traffic the ads will not run.
- Lists go stale: someone added six months ago is no longer in the same context.
Frequent questions
How many visitors do we need to run retargeting?
Ad platforms usually require a minimum audience size, on the order of a hundred people. In practice it makes sense once at least a few hundred people visit the site each month.
Does retargeting annoy people?
With sensible frequency and duration caps, no — it reads as a reminder. What annoys people is uncontrolled exposure for months.
Can we chase people who called but did not buy?
Yes, if you have their contacts and consent to process their data. Uploading your own database into an ad platform is a workable and usually very effective scenario.
Does retargeting work in search?
Yes, there are formats that raise bids for people who have already visited when they search again. It is one of the most effective settings in paid search.
Will it look pushy?
With frequency and duration capped, no — it reads as a reminder. It becomes pushy when the same ad runs for months with no limits.
Does retargeting work with low traffic?
Poorly: ad platforms require a minimum audience size. With a few dozen visitors a day there is simply nobody to build one from.
