Retargeting Ads for Small Businesses: A Plain-English Guide

A homeowner in Mahogany looks at your basement development page on Tuesday night. They like the photos. Then the kids need a bath, the tab gets closed, and by Thursday they're looking at a competitor who happened to show up in their Instagram feed.

Retargeting (Google calls it remarketing) fixes that. It shows ads specifically to people who already visited your site, watched your video or interacted with your business. For small businesses with long decision cycles, it's often the highest-return ad spend in the whole account, because the audience already knows who you are.

How retargeting ads work

When someone visits your website, a small piece of tracking code (the Meta pixel, the Google tag) records the visit. That visitor gets added to an audience list. You then run ads aimed only at that list, on Facebook and Instagram, on Google's Display Network and YouTube, or in Google Search results when those visitors search again.

You can get specific. For example:

• Everyone who visited in the last 30 days
• People who viewed your "kitchen renovation" page but not your "thank you" page
• People who started a quote form and didn't finish
• People who watched at least half of your project video on Facebook or Instagram
• Past customers (uploaded as a customer list, with the right consent)

Do small businesses have enough traffic for retargeting?

This used to be a real barrier. Google required larger audience lists before it would show ads to them. In 2025, Google lowered the minimum audience size to 100 active users in the last 30 days across Search, Display and YouTube, which makes retargeting realistic for many more local businesses. Meta's custom audiences also need at least around 100 people before ads will reliably deliver.

If your site gets a few hundred visitors a month, you can run retargeting. Very small lists mean small spend, which is fine: retargeting is usually a modest slice of the budget.

Retargeting on Google vs. Facebook

For most Calgary service businesses, Facebook and Instagram retargeting is the easiest place to start. If you're already running Google Search ads, adding your website visitors as an audience on those campaigns (so you can bid a bit higher for returning visitors) is a quick next step.

Prospecting ads introduce you. Retargeting ads remind people why they liked you in the first place.

A simple retargeting setup, step by step

1. Install tracking properly. Add the Meta pixel and the Google tag to every page, and set up conversion events for calls, form fills and bookings. Server-side options like Meta's Conversions API help where browsers block tracking.
2. Update your privacy policy. Say that you use cookies and pixels for advertising and how people can opt out. Canadian privacy law expects transparency about this, and both Google and Meta require it in their policies.
3. Build three audiences. All visitors (last 30 days), high-intent visitors (pricing, quote or contact pages), and converters (to exclude, so you're not advertising to people who already booked).
4. Make retargeting-specific ads. Don't reuse your cold ads. Show reviews, finished projects, a guarantee or a time-sensitive reason to book.
5. Cap the frequency. Seeing your ad a dozen times a day feels creepy, not convincing. Keep frequency reasonable and refresh creative every few weeks.
6. Set a modest budget. For a small local business, retargeting is often 10% to 20% of total ad spend, sometimes as little as $5 to $15 a day. It scales with your traffic.
7. Measure booked jobs, not just clicks. Retargeting often helps conversions happen through other channels (people see the ad, then search your name). Watch your overall leads, not just the retargeting campaign's own numbers.

What retargeting ads should say

These people already know your name. Your job now is to remove the reason they didn't call:

• "Can I trust them?" Show Google reviews, before-and-after photos, years in business and licences.
• "Is it too expensive?" Share price ranges, financing if you offer it, or a free estimate.
• "Can it wait?" Give a real reason to act now: limited spring spots, seasonal pricing, or the risk of waiting (for example, hail damage getting worse over winter).
• "How does it work?" A short video walking through your process removes a lot of uncertainty.

Common retargeting mistakes

• Not excluding customers. Advertising "book your free estimate" to someone who booked yesterday wastes money and looks careless.
• Running too long. A 180-day window makes sense for a renovation, not for a drain cleaning. Match the window to how long people take to decide.
• Sending them back to the same page. If the page didn't convert the first time, send them to a stronger landing page with reviews and a clear offer.
• Targeting sensitive topics. Google's and Meta's policies restrict personalized ads based on sensitive information like health conditions. Keep audiences based on services, not personal circumstances.

Is retargeting worth it?

For businesses where customers compare and decide over days or weeks (renovations, landscaping, roofing, cleaning contracts, auto repair), retargeting is usually worth testing. For pure emergency services, where people call the first business they find, it matters less. Either way, it only works once your tracking is solid; if you can't see which ads lead to calls, start with call tracking.

Frequently asked questions

What is the difference between retargeting and remarketing?

They mean essentially the same thing: showing ads to people who already visited your website or interacted with your business. Google uses the word remarketing; most other platforms say retargeting.

How much traffic do I need for retargeting ads?

Google now requires a minimum of 100 active users in the last 30 days for an audience, and Meta needs roughly 100 people in a custom audience. A site with a few hundred visitors a month can usually run retargeting.

How much should a small business spend on retargeting?

Typically around 10% to 20% of total ad spend, often $5 to $15 a day for a small local business. The right budget depends on how much traffic your site gets.

Do I need to update my privacy policy for retargeting?

Yes. Explain that you use cookies and pixels for advertising and how people can opt out. Canadian privacy law expects transparency, and Google and Meta require it.
