The Advantages of Retargeting / Remarketing Advertising

Retargeting (also called remarketing) shows your ads to people who have already visited your website, watched your videos, or are already on your customer list. For a service business, it’s the cheapest insurance you can buy on the traffic you already worked to get. Most visitors leave without calling or filling out a form, and many of them are still deciding. Retargeting keeps your name in front of them while they make up their minds, so when they’re ready, you’re the business they remember. That’s why we think nearly every service business should run at least a basic retargeting campaign, whatever else it’s doing.

Quick Rundown:

  • Most people who visit a service business’s website don’t contact it on that first visit, and the ones still researching tend to take longer and compare more options.
  • Controlled experiments show retargeting brings back more visitors and drives more sales than you’d get without it, and the effect is strongest in the first few days after a visit.
  • You’re only paying to reach people who already showed interest, so less of your budget goes to people who will never need you.
  • You control who sees what, how often, and where: by page visited, by how recently they visited, across display, YouTube, Meta, streaming TV, and your own customer list.

What is retargeting, exactly?

Retargeting is advertising aimed only at people who have already interacted with your business, most often by visiting your website. A small piece of code on your site (like the Google tag or the Meta Pixel) adds visitors to an audience. You then show ads to that audience as they browse other websites, watch YouTube, scroll Facebook and Instagram, or watch streaming TV.

“Retargeting” and “remarketing” mean the same thing for most purposes. Google now calls these audiences “your data” segments, and Meta calls them website custom audiences. The idea is the same everywhere: instead of introducing yourself to strangers, you’re following up with people who already know who you are.

Do most website visitors really leave without contacting you?

Yes. Even pages built specifically to get leads convert only a small share of visitors, so most people who see your site leave without reaching out. Unbounce analyzed more than 41,000 landing pages and 57 million conversions for its Conversion Benchmark Report. The median conversion rate was 6.6% across all industries, 6.1% for professional services, and 6.3% for legal.

Put the other way around, on a typical lead page, more than 9 out of 10 visitors leave without converting. Those are focused landing pages, too. A regular service page or blog post usually converts a smaller share.

That doesn’t mean your site is broken. Plenty of those visitors were never going to hire you. But a real share of them are good prospects who simply weren’t ready yet. Without retargeting, you have no way to reach them again. You paid for that click or earned that visit, and then you let it walk out the door.

How long do people take to choose a service business?

It depends on what they need, but people still researching take longer and compare more businesses, and that’s exactly the group retargeting is built for. BrightLocal surveyed more than 1,200 US consumers about their most recent local business search in its 2026 Consumer Search Behavior study. Overall, 75% chose a business in under 30 minutes, and 72% looked at three or fewer businesses.

The fast decisions are usually urgent ones, like someone who needs a business right now or already has one in mind. The picture changes for people who were “researching costs or options, but not ready to contact anyone yet”:

  • 37% took longer than 30 minutes to decide, and 28% took longer than an hour.
  • 47% looked at more than three businesses.
  • Professional services and trades or home repairs were among the industries where people were least likely to decide in five minutes or less.

Two lessons come out of that. First, the shortlist is short. Being one of the three businesses someone remembers matters a lot. Second, the bigger and more considered the purchase, the longer the window you have to stay in front of them.

In our experience, a big job like a new patio, a roof, or hiring a lawyer often stretches over days or weeks. People get a quote or two, talk it over with a spouse, wait for a paycheck, or just get busy. Retargeting covers that gap.

Do people really forget businesses they looked at?

They don’t have to forget you for you to lose them. They just have to see a competitor more recently than they saw you. Picture someone checking out three landscaping companies on their lunch break. Life gets in the way, and when they come back to the project a few days later, they search again. Whoever they remember best, or whoever shows up first, gets the call.

Research backs up both halves of that. Google’s messy middle research found that people loop back and forth between exploring options and evaluating them, “as many times as they need,” before they buy. Google’s advice to brands is to make sure they’re “front of mind” while customers explore. In a large Stanford experiment on retargeting, the researchers also found that retargeting plays a defensive role: when competitors are also advertising, a consumer who leaves your site is likely to be targeted by a competitor’s ads next. Showing up again keeps you in the running, even if your ad tells them nothing new.

Does retargeting actually work, or does it just take credit for sales you’d get anyway?

It’s a fair question, and the best research says it works. Retargeting causes more people to come back and buy, not just more people to be counted. Retargeting has a reputation problem because the people who see the ads were already interested, so some of them would have come back on their own. The only honest way to measure it is with a controlled experiment, where some visitors randomly don’t see the ads.

Two well-known experiments did exactly that:

  • The “Ghost Ads” study. Researchers measured an online retailer’s display retargeting campaign against a true control group. The ads lifted website visits by 17.2% and purchases by 10.5%, beyond what would have happened without them. (Published in the Journal of Marketing Research, 2017.)

Both studies were with online retailers, not local service businesses, so don’t expect those exact numbers. But they show that the effect is real and that it’s incremental.

The research also has a caution. A study from MIT and London Business School found that ads showing the exact product someone viewed weren’t automatically better. They worked best once someone’s preferences had narrowed, and more general brand ads did better early on (Lambrecht & Tucker, Journal of Marketing Research, 2013). In other words, retargeting works, but the message has to match where the person is in their decision.

Why should every business run retargeting, at minimum?

Because it protects every other dollar you spend on marketing. Your Google Ads, SEO, social posts, streaming TV, mailers, and word of mouth all do the same job: they get people to look you up. Retargeting is what follows up with the ones who looked and didn’t call yet.

Here’s why we consider it a baseline, not an extra:

  • It works on traffic you already have. You don’t need to find new people. Everyone in the audience has already shown at least some interest.
  • It scales to your size. The audience is only as big as your site traffic, so a small business has a small audience and a small bill.
  • It makes your other ads work harder. If someone clicks your search ad and leaves, retargeting gives that click a second and third chance.
  • It makes a small business look established. When a homeowner sees your name on a news site, on YouTube, and then on their TV, you start to feel like the obvious choice.
  • It’s flexible. It works for a two-truck landscaping company and a regional law firm. You just shape it differently.

Is it the right first move for every business? Not always. Retargeting needs people coming to your site in the first place. If almost nobody visits yet, it can’t do much until something else brings traffic. But once you have steady traffic, running no retargeting at all is usually leaving leads on the table.

Is retargeting cheaper than other advertising?

It’s usually more efficient, but not always cheaper per ad shown. You pay to reach a smaller, warmer group, so far less of your budget is wasted on people who will never hire you. This part gets oversold, so here’s the honest version.

  • Cost per impression can be higher. Because you’re bidding on specific people instead of anyone in an area, each impression can cost more than broad display ads. A tiny audience can also be hard to reach often enough.
  • Total spend is naturally limited. You can only show ads to as many people as visited your site. A local business with a modest amount of traffic simply can’t spend a fortune on retargeting, even if it tried.
  • Waste is lower. With broad advertising, most of the people who see your ad don’t need your service right now. With retargeting, every person has already looked at what you offer.
  • The cost per lead is what matters. Because the audience is already interested, retargeting often produces leads at a lower cost than reaching strangers. In our experience, that’s where it earns its keep. The experiments above show the lift is real, but your exact cost per lead depends on your market, your offer, and how the campaign is built.

Google itself describes this targeting as reaching people who have already interacted with your business, when they’re more likely to buy. That’s the core of the efficiency argument: same budget, aimed at warmer people.

How can a retargeting campaign be shaped?

Almost every part of it can be shaped: who’s in each audience, how long they stay there, what they see, how often, where, and who gets left out. This is where a basic campaign and a great one separate.

By what they looked at:

Someone who read your “patio installation” page needs a different ad than someone who read a blog post about lawn care. Platforms let you build audiences from rules about which pages someone visited. That way a patio visitor sees patios, and a personal injury visitor sees your injury practice, not your estate planning.

By how recently they visited:

Timing matters more than most people think. In the Stanford study, about one-third of the first week’s effect happened on the first day, and the researchers warned that if someone isn’t reached in the first week, later ads might not be effective. A common approach is to show up more in the first few days and back off over time. Platforms let you choose how long someone stays in an audience. Google allows up to 540 days, and Meta’s website audiences allow up to 180 days. For an emergency plumber, a few weeks may be plenty. For a law firm or a big remodel, a longer window makes sense.

By how often they see you:

There’s a line between staying top of mind and being annoying. Frequency caps limit how many times one person sees your ads in a day, week, or month. Google offers them for Display and Video campaigns. Getting the number right is part art, part watching the data.

By the order of the messages:

You don’t have to say the same thing every time. A sequence might start with who you are and why people trust you, move to reviews or before-and-after photos, and finish with a reason to reach out now, like a free estimate. Lambrecht and Tucker’s research above is a good reminder: match the message to where the person is in their decision.

By who’s left out:

Good retargeting is as much about who you don’t show ads to. People who already filled out a form or called should be removed or moved into a different message, so you’re not paying to chase leads you already have. Your current customers can be excluded from new-customer offers, too. Excluding people who only visited your careers page or client login is another easy win.

By channel:

Retargeting isn’t just banner ads. The same audience can be reached in several places:

  • Google Search. Your bids can change when a past visitor searches again, which is often exactly when they’re ready to call.
  • Your customer list. Google’s Customer Match and Meta’s customer list audiences let you reach past customers and leads by uploading their information securely. That’s useful for repeat services, seasonal reminders, and asking for referrals. Each platform has its own eligibility rules.

What it can look like:

Here’s an illustration, not a real client. A landscaping company runs Google Ads for “patio installation.” A homeowner clicks, looks at the patio gallery, and leaves without asking for a quote. Over the next few days, they see a photo of a finished patio on a news site and a short video on YouTube. A week later, the company’s 15-second commercial plays during a show they’re streaming. When they’re ready to move forward, they search again. The name they recognize is the one they call. The other companies they looked at that first day never came back up.

What about privacy and consent?

Retargeting is legal and widely used, but it has rules, and doing it respectfully protects your reputation as well as your compliance. People care about this. In a 2023 Pew Research Center survey, 81% of US adults said they were concerned about how companies use the data they collect about them.

A few basics:

  • Your privacy policy should disclose that you use cookies and advertising tools.
  • Some topics can’t be retargeted. Google restricts personalized ads in sensitive categories like health, relationship hardships (which includes divorce services), and negative financial status. Some law firms and medical practices have to use other approaches.
  • Never pass personal information, like an email address in a page URL, to ad platforms through tracking code. Google’s policy forbids it.
  • Don’t be creepy. Reasonable frequency, a sensible time window, and ads that are helpful rather than “we saw you looking” go a long way.
