Blog · Advertising & Retargeting
The ads that bring back people who already visited you, what 2025 changed, and how to launch without overspending.
Someone visits your site on a Tuesday night. They read your services page, hesitate, close the tab to go make dinner. They will probably never come back on their own. It's not that they hated you: life just interrupted them. Retargeting is the art of politely reminding them you exist two days later, while they scroll their feed. And unlike what most people believe, it's one of the rare paid tactics that plays in favour of small budgets, not against them. Let's see why, at what threshold it becomes useful, and how to launch it cleanly.
Retargeting (also called remarketing) means showing an ad to people who already had some contact with you: visited your site, watched a video, opened your profile, clicked a post. They are recognized through a small piece of code on your site (the pixel or tag), or through a list you provide, and ads are reserved for them alone.
The nuance is the whole interesting part. Classic advertising, called prospecting, speaks to strangers: it's expensive because you have to convince cold. Retargeting speaks to people who are already warm, who know you a little. You don't start from zero, you pick up a conversation already begun. That is where the return on spend really diverges, and it's also what makes retargeting affordable for a small business: your retargeting audience is small, so covering all of it costs little.
Why bother? Because the first visit rarely converts. On online stores, the Baymard Institute, which pools around fifty studies, measures an average cart abandonment rate of 70.19 percent (Baymard Institute, updated September 2025). Seven filled carts in ten leave without a purchase. On the services side, nobody fills a cart, but the reflex is the same: people look, compare, put it off. Retargeting exists to recover a share of that "later."
We heard a lot that retargeting was doomed, killed by the "end of cookies" and the privacy wave. The reality of 2025 runs the other way, and two concrete decisions made it more accessible to small businesses, not less.
First, third-party cookies are staying. After years of contradictory announcements, Google confirmed in April 2025 that it would not remove third-party cookies from Chrome, and would not even add a dedicated choice prompt (Google Ads, frequently asked questions). Classic cookie-based retargeting, the kind most tools still use, therefore keeps working in the most widely used browser.
Second, the entry threshold dropped. In 2025, Google lowered the minimum size of a retargeting audience to 100 active people over 30 days, across all its networks (Display, Search, YouTube), whereas Search previously required 1,000 (Search Engine Land). In practice, a business that gets around a hundred qualified visitors a month can now retarget, which was out of reach last year.
Should we declare victory? No, and here's the honest caveat. Third-party cookies are losing effectiveness because more people block them, and above all because Apple has about three in four iPhone users decline tracking. Your visitor audiences shrink accordingly. The right answer is not to give up, but to lean on your own data: engagement audiences built inside the apps (people who watched your video or visited your Facebook and Instagram page) and your customer lists escape those blocks. They become the solid base of retargeting that holds.
That's the real question to ask before spending a dollar. Retargeting doesn't invent an audience: it recycles the one you already have. If there's almost no one to recycle, there's nothing to do. Here are the starting thresholds of the two big platforms.
| Platform | Minimum audience to serve | Key point |
|---|---|---|
| Google Ads (Display, Search, YouTube) | 100 active people over 30 days | Threshold lowered in 2025 (was 1,000 in Search) |
| Meta (Facebook and Instagram), site audience | Around 100 people | Delivery starts near 100 matched people |
| Engagement audiences (video, page, profile) | Varies, often reached faster | Do not depend on third-party cookies, more stable |
The reading is simple. If you need 100 visitors over 30 days to start, your site has to welcome at least a hundred qualified people a month. Below that, retargeting spins empty: the audience never reaches serving size. The right move then is not to force it, but to go get traffic first: local search, your business listing, or a first prospecting campaign. I explain how to kick off that part in my guide to getting started with Google Ads as a Metro Vancouver small business. Retargeting comes after, when there are people to bring back.
Once the traffic is there, the setup comes down to five moves. None needs a big budget, only discipline.
Nothing beats numbers to clear up the "it's expensive" myth. Take a physiotherapy clinic around Metro Vancouver. Its site gets about 900 visitors a month. Of those, roughly 220 view the services page or the contact page: those are the high-intent people, the ones worth bringing back. The table below shows why covering them costs so little.
| Targeted segment | Size (window) | Cap | Impressions / month | Estimated cost (CPM 10 to 14 $) |
|---|---|---|---|---|
| Visitors of services and contact pages | 220 (30 days) | 3 / week | About 2,600 | 30 to 40 $ |
| All recent visitors | 700 (60 days) | 2 / week | About 5,600 | 60 to 80 $ |
| Total to cover both groups | 90 to 120 $ / month | |||
The figures are orders of magnitude, to confirm for your market and your creative (CPMs vary), but the logic holds every time. Because the audience is small and already warm, covering all of it costs tens of dollars, not hundreds. A budget of 150 to 250 dollars a month is more than enough: the surplus goes to widening the window to 90 days or testing a second ad. In other words, the limiting factor is not your wallet, it's your traffic. That's the exact opposite of cold prospecting, where budget decides everything. If you're still choosing between building this presence on Google or on Meta, my comparison of Google Ads versus Meta Ads for a small business helps you decide based on your customers.
Most failed retargeting fails for the same reasons. They're easy to avoid once named.
No, and 2025 confirmed it. In April 2025, Google announced it would not remove third-party cookies from Chrome. Classic cookie-based retargeting still works. It does lose reach, because more people block cookies and, above all, because Apple has about three in four iPhone users decline tracking. The fix is simple: base your retargeting on your own data (in-app engagement audiences, customer lists), which do not depend on third-party cookies.
Less than people think, because the audience you retarget is small and already warm. For a Metro Vancouver small business that gets a few hundred visitors a month, a budget of 150 to 250 dollars a month is often enough to stay in front of every recent visitor, with a frequency cap. The real limit is almost never the budget: it's traffic volume. Below roughly a hundred qualified visitors a month, invest first in attracting people.
Enough to be remembered, not so much that you annoy. A common consumer benchmark sits around three to five impressions per week, set with a frequency cap in the platform. For someone who just abandoned a quote request or a cart, you can raise the pace for two or three days, then stop. Without a cap, the same ad loops, burns budget and feels like it's following people everywhere.
