Before tuning frequency, timing or creative, check the size of the audience you are retargeting. For a great many local contractors it is a few dozen people, and almost every retargeting problem, including the ads feeling relentless, follows from that.
Do the arithmetic on your own traffic
Suppose your site receives six hundred visitors a month. That sounds respectable for a local trade, and it is.
Now build the audience. Exclude the ones who already called or filled in a form, because retargeting people who converted wastes money and irritates customers. Exclude anyone outside your service area. Exclude the bounces who left in three seconds. Then hold it to a window of, say, a fortnight.
What remains is frequently under a hundred people. That is the audience your campaign is actually addressing.
What platforms do with an audience that small
Advertising networks impose minimum audience sizes before a list will serve, partly for delivery and partly to prevent individuals being singled out. The thresholds differ by network and by placement: display lists typically need far fewer people than search or video lists, and they are changed from time to time, so it is worth checking the current figures rather than trusting a number from an article.
The practical consequence is consistent regardless. Below the threshold, nothing delivers, and the campaign quietly spends nothing while appearing to be live. Just above it, the budget lands on a very small group of people, repeatedly.
Why this is the cause of your frequency problem
Here is the connection that usually goes unmade. Frequency is not a setting you choose in isolation; it is budget divided by audience.
Put a modest daily budget against ninety people and the platform will spend it by showing those ninety people your advertisement over and over, because there is nobody else to show it to. Capping frequency then just means the budget goes unspent.
So an audience that is too small does not merely underperform. It manufactures exactly the relentless, follows-you-everywhere experience that gives retargeting its reputation, and no amount of creative refreshing fixes it.
What to do instead of tuning the dials
- Lengthen the window before shortening it. The usual advice is to keep windows short, and that is right when volume allows. When it does not, a longer window is what makes the audience viable at all. Balance the two honestly rather than following the rule.
- Combine sources. Site visitors, video viewers, people who engaged with your page or profile, and your customer list can often be pooled into something large enough to work.
- Match the budget to the audience. A small list needs a small daily budget, or the spend concentrates. This is the single most common misconfiguration.
- Fix the traffic first. Retargeting can only reach people who already came. If the site receives few visitors, the constraint is upstream, and money spent on retargeting is money not spent on the search campaigns that would fill it.
When retargeting is worth it for a trade
It works best where deliberation is long and traffic is reasonable: replacements, roofs, full system installations, anything a household thinks about for weeks. Those visitors are worth reaching again, and there are usually enough of them.
It works poorly on emergency traffic. That visitor either called you or called somebody else within the hour, and following them for a fortnight afterwards reaches a person whose problem is already solved.
Frequently asked questions
How big does a retargeting audience need to be?
Above the platform’s stated minimum for the placement you are using, and comfortably above it if the budget is anything but small. The figures vary by network and change, so check the current ones rather than relying on a remembered number.
My retargeting campaign is not spending. Why?
Most often the audience is below the minimum to deliver. The campaign looks active and reaches nobody.
Why do my retargeting ads feel so repetitive?
Because the budget is being divided among very few people. Frequency is budget divided by audience: with a small list, high frequency is arithmetic, not a settings mistake.
Should I retarget emergency service visitors?
Rarely. That decision is made within the hour, so a fortnight of following reaches someone whose problem is long since resolved.
Where to start
Open your audience in the ads manager and read the estimated size. If it is small, stop adjusting frequency caps and creative: the dials are not the problem, and the answer is either more traffic, a wider window, or not running the campaign at all.
