What is remarketing?

Remarketing (often called retargeting) shows ads to people who already interacted with your brand—site visit, app, video, customer list—to bring them back to convert. On Google and Meta, remarketing audiences and dynamic ads recall products or pages viewed. Effectiveness comes from audience warmth, not cold volume.

In one sentence

Remarketing re-engages people who already know you to finish the conversion.

Key points

  • Targets past visitors or customers, not cold strangers.
  • Frequency and time windows prevent ad fatigue.
  • Messages should match stage (cart, pricing, content).
  • Consent and clean lists are non-negotiable.

What does remarketing mean?

Google often says remarketing; Meta says retargeting—same idea: re-engage a warm audience. Pixel lists, Google Ads tags, and Customer Match power campaigns.

Dynamic remarketing shows viewed products; classic remarketing pushes one message (demo, promo, proof).

Without exclusions (recent buyers, employees) and frequency caps, campaigns annoy and waste spend.

How do you set up remarketing?

  1. 01

    Tags and consent

    Pixel / Ads tag + compliant consent mode.

  2. 02

    Segment audiences

    Cart, pricing, blog, customers 180 days—distinct messages.

  3. 03

    Cap frequency

    Caps + 7/14/30-day windows by cycle length.

  4. 04

    Measure incrementality

    Compare remarketing CPA vs prospecting; exclude converters.

A concrete example

A Quebec City design shop sees 70% cart abandonment. A 14-day Meta “finish your order” campaign with local delivery proof recovers 12% of abandoners at higher ROAS than prospecting.

Why it matters for Quebec SMEs

You already pay to bring traffic. Remarketing recovers some of those visitors before they buy from a competitor—especially on B2B cycles or local carts.
