TL;DR: Retargeting shows your ads to people who have already visited your website, on Google, Facebook, Instagram, and thousands of other sites. It typically costs 30 to 50% less per click than cold advertising and converts at two to three times the rate, but only delivers results when you already have consistent website traffic to build from.

What Is Retargeting Advertising and Is It Worth It for Your Business?

Retargeting lets you show ads specifically to people who have already visited your website. It is one of the few advertising tactics that targets warm audiences rather than cold ones, which is why it tends to convert better and cost less per lead than standard prospecting campaigns.

What Retargeting Actually Means

When someone visits your website and leaves without calling or filling in a form, they do not disappear from reach. Retargeting is the mechanism for showing them your ads again after they leave, on the other websites, apps, and platforms they visit throughout their day.

The technical setup is straightforward. A small piece of code, called a pixel or tracking tag, is placed on your website. When someone visits, the pixel adds them to an audience list inside your ad platform. That platform can then show them your ads on Google's display network, Facebook, Instagram, YouTube, and millions of other websites, for days or weeks after their visit.

From the business owner's perspective, the result is that someone who looked at your scaffolding quote page on Tuesday starts seeing your ads on Instagram by Wednesday. You are not paying to reach everyone in Adelaide. You are paying to stay visible to the specific people who already showed enough interest to visit your site.

The Difference Between Retargeting and Standard Advertising

Standard digital advertising, whether Google Search or Facebook prospecting, targets cold audiences: people who have never heard of you but match a profile based on demographics, interests, search behaviour, or location.

Retargeting targets warm audiences: people who have already visited your website, watched your video, interacted with your social content, or clicked a previous ad.

The performance difference is significant. Warm audiences convert at two to three times the rate of cold audiences. Because you are bidding on a small, specific list rather than a broad audience, the cost per click is typically 30 to 50% lower. The tradeoff is volume. Your retargeting audience is always smaller than your prospecting audience because it is capped by how many people have visited your site in the past 30 to 90 days.

How Retargeting Works on Google vs Meta

Google's display network covers millions of websites, apps, YouTube, and Gmail. Once the Google tag is installed on your site, you can serve banner ads, responsive display ads, and video ads to past visitors as they browse across Google's network.

This works particularly well for longer buying cycles. If someone is researching commercial fit-out companies for a project they plan to start in three months, they will visit multiple websites over weeks before requesting quotes. Google retargeting keeps your brand visible throughout that research window rather than leaving you dependent on whether they happen to search again and find you.

The Meta pixel works the same way within the Facebook and Instagram ecosystem. Because people spend significantly more time scrolling social feeds than reading individual websites, Meta retargeting tends to generate more impressions per person over a given period.

Meta's creative formats also work well for retargeting. A video testimonial, a before-and-after project photo, or a strong offer can be shown in a format that feels native to how people already use the platform, rather than the banner ad format typical of Google Display.

Most businesses benefit from retargeting on both. The audiences overlap but are not identical. Some past visitors are more active on Instagram; others browse news sites in Google's display network. Using both increases the probability that a warm prospect sees your brand again before they make a decision.

What Retargeting Costs in Australia

There is no fixed price. You set a budget and pay for clicks or impressions as they occur.

Rough benchmarks for Australian businesses in 2026:

• Google Display retargeting: $0.30 to $1.50 per click depending on industry and audience size
• Meta retargeting: $0.50 to $2.00 per click depending on creative quality and competition
• Minimum effective budget: $300 to $500 per month per platform to generate enough frequency to have an impact

For context, if you are already spending $2,000 per month on Google Search, adding $400 in Google Display retargeting is a reasonable complement. For the budget guide on how to structure your total Google Ads spend, see What Is a Good Google Ads Budget for a Small Business in Australia?.

When Retargeting Is Worth It

Your website receives at least 300 to 500 unique visitors per month. Below this threshold, the audience pool is too small for platforms to deliver ads efficiently or with enough frequency to influence behaviour.

Your sales cycle is longer than a single visit. Purchases that involve comparing multiple providers, such as home renovations, professional services, commercial equipment, or B2B services, are retargeting's natural territory. The longer the decision takes, the more touchpoints matter.

Your current conversion rate from cold traffic is below 5%. If most visitors leave without contacting you, that is not unusual. The post-click gap is a real phenomenon. Retargeting is one mechanism for recovering some of those lost visitors.

Your website has very low traffic. A retargeting audience of fewer than 100 people will result in either no ad delivery or extremely high ad frequency that annoys the same small group. You need volume before retargeting has anything meaningful to work with.

You are not yet running prospecting campaigns. Retargeting amplifies existing traffic; it does not create it. If you have no consistent flow of new visitors from Google Ads, Meta Ads, SEO, or other sources, retargeting will have almost nothing to show ads to.

Your prospecting campaigns are already broken. If your Google Ads are not generating leads, the problem is usually the campaign structure, the landing page, or the offer. Retargeting those same non-converting visitors replicates the same result. Fix the foundation first, then add retargeting as a second layer.

How Much of Your Budget Should Go to Retargeting?

A common starting allocation is 15 to 25% of total digital advertising spend on retargeting.

If you are spending $2,000 per month on Google Search, allocating $300 to $500 toward Google Display retargeting is a practical starting point. As your website traffic grows, retargeting can productively absorb more budget because the audience pool is larger.

If traffic is low, concentrate budget on prospecting first. Build the audience before investing in following it.

Which Businesses Retargeting Works Best For

Retargeting is most effective for businesses where buying decisions take time and involve multiple touchpoints.

It works well for Adelaide professional services businesses (accountants, lawyers, financial advisors, consultants) because trust takes time to build and prospects compare multiple firms before engaging. It also works well for home services (builders, pool companies, renovators, landscapers), commercial suppliers, B2B businesses with long sales cycles, and any service business where the initial visit rarely results in an immediate enquiry.

It is less effective for emergency services where buyers call the first available result, impulse purchases, or very local businesses generating minimal online traffic.

FAQ

How long does retargeting follow someone after they visit my website?

You set the window, typically between 7 and 180 days. For most lead-generation businesses, 14 to 30 days is the practical range. Beyond that, the visitor has either already made a decision, lost interest, or the timing has changed significantly. Showing ads to someone who visited your site five months ago has very low conversion value and wastes budget.

Does retargeting work if I am only running Google Ads and not Meta Ads?

Yes. Google Display retargeting and Meta retargeting are independent channels. You can run retargeting on either platform regardless of where your prospecting runs. Many businesses run Google Search for cold prospecting and Meta retargeting for follow-up, or the reverse, depending on where their customers spend their time online.

Is there a minimum budget to make retargeting worthwhile?

The practical minimum is around $300 per month per platform. Below this, your ads may be approved but not delivering because the audience size or budget does not support consistent delivery. Combined with at least 300 to 500 monthly website visitors, a total retargeting budget of $600 to $1,000 per month across Google and Meta is a reasonable starting point for an Australian SME.

Will retargeting fix my Google Ads if they are not converting?

No. Retargeting is not a fix for a broken prospecting campaign. If your Google Ads are generating clicks but not leads, the issue is usually the landing page, the offer, or the campaign targeting. Retargeting those same non-converting visitors will produce the same result. Resolve the conversion problem first, then layer retargeting on top to capture the people who were close but needed another touchpoint to decide.

Does retargeting mean my ads are stalking people?

Retargeting is standard practice across the digital advertising industry and most website visitors understand how it works. The key to it feeling helpful rather than intrusive is frequency capping, which limits how many times the same person sees the same ad in a given period. A properly configured campaign will show your ad two to four times per week per person, not twenty times per day. Set frequency caps in your campaign settings from the start.
