Retargeting ads are how you get a second shot at the people who visited your site, didn't call, and clicked away — which is nearly everyone. On a typical local service site, well over 90% of first-time visitors leave without doing anything. Retargeting quietly follows them around the web with a reminder to come back. Used right, it's some of the cheapest lead recovery you can buy.
How it actually works
A small piece of code (a pixel or tag) sits on your site. When someone visits, it drops an anonymous marker in their browser. Later, when that same person is scrolling Facebook, reading the news, or watching YouTube, your ad shows up. They didn't give you their email or phone — the ad system just recognizes the marker and serves your ad to them.
You're not paying to reach cold strangers. You're paying to reach people who already looked at your business. That's why the numbers usually work: warm traffic converts at a much higher rate than cold.
Where your ads can show
Two main systems, and most local businesses use one or both:
- Google Display / YouTube: banner and video ads across millions of sites and apps, plus YouTube.
- Facebook and Instagram: ads in the feed and stories of people who visited your site.
For a local plumber or detailer, both are fine. Start with whichever platform you already understand.
When retargeting is worth it — and when it isn't
Retargeting needs traffic to work. If your site gets 30 visitors a month, the audience is too small to bother; you'll spend more time setting it up than you'll earn back. As a rough floor, you want a few hundred monthly visitors before it earns its keep.
It shines for services with a longer decision — a roof replacement, a kitchen remodel, cosmetic dentistry, a $2,000 detailing membership. People shop around and think it over for days. A well-timed reminder brings them back. For a true emergency (burst pipe at midnight), retargeting matters less — they call the first result and it's over.
Don't be creepy
The fastest way to waste retargeting is to hammer the same person with the same ad 40 times. It annoys people and it makes you look desperate. Two protections:
- Frequency cap: limit how many times a day one person sees your ad — three or four is plenty.
- Membership duration: stop showing ads to someone 30 to 60 days after they visited. If they haven't come back by then, they're gone; keep spending elsewhere.
Give them a reason, not just a reminder
A retargeting ad that just says your name is weak. Give the returning visitor something new: a limited offer ("$50 off if you book this week"), a review that answers a common doubt, or a plain nudge ("Still need that AC looked at? We have slots Thursday"). They already know who you are — the job now is to remove whatever made them hesitate the first time.
Watch out for tracking rules
Between iPhone privacy settings and cookie limits, retargeting audiences are smaller and less precise than they were a few years ago. It still works, but the pool is narrower — another reason it pays off best when your site already gets steady traffic. Set your frequency caps, give people a real reason to return, and treat retargeting as the closer that finishes what your search ads started, not a standalone strategy.
