Retargeting almost always reports excellent numbers. It is also the channel most likely to be taking credit for work it did not do, because by definition it advertises to people who already know you and were already likely to come back.
Why the reported figures flatter it
Consider a homeowner who visits your site on Tuesday, thinks it over, sees a retargeting advertisement on Thursday, and rings you on Friday.
Most reporting hands that booking to the retargeting campaign, because it was the last advertisement touched. But the honest question is whether they would have rung anyway. Some proportion of them would; they had already found you, already read your page, and already formed an intention.
So a retargeting campaign can show a superb return while adding very little, and it will do that most convincingly when your other marketing is working well, because a healthy site sends it a steady supply of people who were already going to convert.
The measurement that actually answers it
The question is not how many conversions retargeting was credited with. It is how many more you got than you would have without it, the incremental ones.
The way to find out is to withhold it from some people. Hold back a share of the audience, show them nothing, and compare their conversion rate against the group who saw the ads. The difference is what retargeting actually contributed. Some platforms offer this as a built-in test; otherwise it can be approximated by excluding a slice of the audience.
The other honest method is cruder and works for any contractor: turn it off for a month and watch total bookings, not campaign-reported ones. If nothing moves, you have learned something worth more than the campaign cost.
What this means for a small budget
None of this makes retargeting worthless. It makes it a supporting channel that should be funded after the ones that create demand rather than before.
Search advertising and local search bring people who did not previously know you exist. Retargeting can only speak to people who already arrived. If the site receives few visitors, retargeting has almost nobody to work with and its impressive percentages describe a handful of people.
Fund the channels that fill the top of the funnel first, then add retargeting to recover the ones who slipped away.
Where it genuinely adds something
- Long deliberation. Replacements and large projects, where weeks pass and competitors are being compared. Here a reminder plausibly changes an outcome.
- Quote follow-up. Somebody who received an estimate and has not decided is a small, high-value audience where presence matters.
- Seasonal re-entry. Reaching spring’s researchers when autumn arrives, which is a genuinely new prompt rather than a repeated one.
What it adds least to is work decided in an hour, where the decision was made long before your second impression.
Do not let it cannibalise your own reporting
A practical consequence worth watching: if retargeting is credited generously, it will look like your best-performing campaign, and budget will migrate towards it. That moves money from the channels bringing new people to the channel that talks to people the others already brought.
Left unchecked, the account slowly optimises itself into a smaller and smaller circle.
Frequently asked questions
Why does retargeting always look so profitable?
Because it advertises to people who already know you and were already likely to return. Last-click reporting hands it conversions that would often have happened regardless.
How do I tell whether retargeting is actually working?
Withhold it from part of the audience and compare, or switch it off for a month and watch total bookings rather than campaign-reported ones.
Should retargeting come before or after search advertising?
After. Search brings people who did not know you existed; retargeting can only speak to people who already visited. Fund the source before the follow-up.
Where does retargeting add the most?
Long-deliberation work, outstanding quotes, and seasonal re-entry. It adds least on emergency jobs, which are decided before a second impression ever lands.
Where to start
Look at what share of your reported conversions your retargeting campaign is claiming. If it is a large share on a small audience, that is a sign of over-crediting rather than performance, and a month with it switched off will tell you which.
