Remarketing: When It Helps and When It Annoys
Putting an ad back in front of someone who already knows you works — until it becomes nagging. Where the line sits.
Remarketing works for a simple reason: it speaks to people who have already met you. But that same reason makes it irritating when badly set up, because it keeps pushing at people who have already decided.
Segment by behaviour, not by presence
Someone who glanced at a page for three seconds and someone who half-filled the form are not the same audience. Treating them together means saying the wrong thing to both.
- Brief visit: remind them what you do, ask for nothing.
- In-depth visit: address the most likely objection.
- Action started, not finished: remove the practical obstacle.
- Existing customer: exclude them, or talk about something else.
The time window
The longer the buying cycle, the wider the window should be. For an impulse purchase, chasing someone for sixty days is just spend: after a few days the interest is gone.
The frequency cap
Beyond a certain point the same ad stops persuading and starts irritating. It's worth setting a ceiling and rotating the creative before the annoyance sets in.
The exclusions almost nobody sets
People who already bought, already wrote, or asked not to be contacted. These exclusions save budget and, more importantly, avoid making someone who already trusted you feel hounded.
Remarketing should remind, not pursue. The line is frequency.
