Retargeting: What It Is and How It Works

Retargeting is advertising that only people who already interacted with your business see: they visited your website, opened a product page, scrolled your Instagram. Most visitors do not buy the first time. Retargeting brings them back a day, a week or a month later. But there is a catch: a small business in Kyiv often has nobody to retarget. The website gets 30 visitors a week, and the remarketing audience never grows big enough. This article explains how retargeting works, where it breaks, and how to fill it with real people from your neighbourhood through a screen in a coffee shop.

What retargeting means in plain words

Your website tags each visitor with a pixel — the Meta pixel, a Google tag or another tracker. The ad platform remembers that person in a list. Later you show ads only to that list, not to everyone.

Retargeting vs remarketing — in everyday practice they are synonyms. Google calls the tool "remarketing", Meta calls it "website custom audiences". The difference is a nuance: classic remarketing more often means a repeat contact by email or messenger, retargeting means ad networks. For a small-business budget the logic is the same.

How retargeting works: 4 steps

1. Tag. Install the Meta pixel and a Google tag on your site. Without them no audience is collected.
2. Segment. Split visitors: "viewed the service page", "added to cart", "visited but did not submit a request".
3. Ad. Each segment gets its own message. People who viewed the price list get a discount. People who only opened the home page get reviews.
4. Window. Choose how many days a person stays in the audience: 7, 30 or 90. For a coffee shop or beauty salon long windows add little; for renovation or real estate it is the opposite.

Retargeting is the bottom part of the sales funnel. It does not create demand; it converts people who are already interested.

Why retargeting fails for small businesses

A typical local-business story: the owner installs a pixel, launches a campaign and a week later sees "audience too small". There are three reasons.

The second problem hurts most. A barbershop in Lukianivka does not need website visitors from Troieshchyna. It needs people who live and drink coffee within 1 km. More on that in our article on hyperlocal advertising.

An offline screen as a retargeting audience source

Here is a combination few businesses use. A screen in a coffee shop shows your video with a QR code. A guest scans the code, lands on your site — and the pixel adds them to your audience. Now this is not a random click from the internet but a person who physically sat in a venue 500 metres from your business.

How to set it up:

1. Video with a QR code. 10–15 seconds, one offer, a large QR code. How to make people scan it — see QR codes in indoor advertising.
2. A separate landing page. For example, /coffee-promo. This separates the offline audience from other traffic.
3. UTM tags. Add utm_source=hostad and the venue name. Instructions are in UTM tags in a QR code.
4. URL-based audience. In Meta and Google, create an audience "visited /coffee-promo" with a 30-day window.
5. Follow-up. Show these people ads on Instagram and Google with a concrete reason to come: a discount, an open booking slot, a new product.

Even guests who did not scan the QR code see your video every 2 minutes while they drink their coffee. When they later meet your ad in their feed, the brand is already familiar. This is the same frequency effect we described in the article on brand awareness.

What this combination costs

Retargeting itself is cheap: the audience is small, so Meta or Google spend starts at a few hundred hryvnias a month. The real question is where to get a quality audience.

On HostAd the price is visible on every screen's page before you book. For example, on the Coffee Gang screen the base rate is 50 UAH per second of airtime per month: a 10-second video costs 500 UAH a month, and the board's monthly reach is about 5,000 people. No agency markup, no quarterly contract.

Sample monthly budget for a local service business:

This is an illustration, not a promised result. The real number of scans depends on the creative and the offer.

How HostAd helps fill your retargeting audience

• Geography, not random traffic. HostAd currently has 29 screens in craft coffee shops and bars across Kyiv — in Lukianivka, Solomianka, Holosiiv and the Shevchenkivskyi district. You pick the points near your business on the map.
• QR tracking in your stats. Every scan goes through the HostAd tracking domain and is counted in your dashboard. You see how many people came to your site from each venue.
• Monthly booking. Run one month as a test, check whether the audience builds up, and only then scale.
• Self-service. Pick a screen, upload your video, pay — no calls and no commercial proposals.

Common retargeting mistakes

• One ad for everyone. A person who reached the cart and a person who only opened the home page expect different things.
• No frequency cap. 15 impressions of the same banner a day are irritating. Set a cap of 2–3 impressions a day.
• No exclusions. People who already bought must drop out of the audience.
• Online sources only. If only paid internet traffic fills the audience, you pay twice for the same person. An offline screen adds new people from the neighbourhood.

Conclusion

Retargeting is one of the cheapest ways to bring a customer back — but only if there is someone to bring back. For a local business the best audience is people nearby. A coffee-shop screen with a QR code delivers exactly them: they see your brand offline, visit your site and land in your remarketing list.

Pick screens near your business on the HostAd map and launch your first month of the "screen + retargeting" combination.
