The useful timing question in retargeting is not what hour of the day to advertise. It is how long after somebody visited you are still worth showing to, and for a trade that answer changes completely depending on what they came for.
Recency beats scheduling
Most timing advice concerns dayparting: find the hours your audience is active and concentrate there. For a small local audience this is close to meaningless, because the audience is too small for hourly patterns to be readable, and restricting hours makes an already thin list thinner.
What genuinely changes results is recency, how many days it has been since the visit. Someone who looked at your site this morning is in a different state from someone who looked five weeks ago, and treating them identically is the actual timing mistake.
Match the window to the decision, not the calendar
- Emergency work: hours, not days. That visitor called somebody within the hour. A window measured in weeks reaches a household whose problem was solved before your second impression.
- Repairs and maintenance: several days. Long enough to cover somebody who meant to ring and got distracted, short enough not to follow a completed job.
- Replacements and large projects: weeks, legitimately. Quotes are gathered, finances arranged, partners consulted. This is the case where retargeting earns its place, and where a longer window is right rather than lazy.
Running one window across all of these: usually thirty days, because it is the default, is too long for most of your traffic and sometimes too short for the work worth the most.
Tier by recency where you have the volume
If the audience supports splitting, treat the recent and the distant differently. The first few days after a visit are when somebody is still actively deciding, and are worth a higher share of the budget. The later stretch is a lighter presence, less often, aimed at recognition rather than persuasion.
If the audience does not support splitting, do not split it. Two audiences that are each too small perform worse than one that works.
The seasonal version of the same question
Contractor demand is seasonal, which changes what recency means. Somebody who read about heating repairs in April is not a hot lead in April; they may be an excellent one in October.
That is a long-window audience with a light touch, activated when the season turns, rather than a fortnight of pursuit in spring. It is one of the few genuinely good uses of a lengthy retargeting window for a trade.
Timing around the job itself
The best-timed advertisement a contractor can run often goes to people who are already customers.
A service due a year after installation, a seasonal check before the weather turns, a filter or a drain that needs attention on a known interval: these have a right moment that you know and the platform does not. Reaching a past customer at that moment converts better than anything aimed at a stranger, and it is scheduled from your own records rather than from a targeting setting.
What not to bother with
Hour-of-day and day-of-week restrictions, for most local trades. The audience is too small to reveal a reliable pattern, and the restriction mainly reduces delivery.
The exception is a business that genuinely cannot take calls at certain times and does not want to pay for clicks then, which is a budget decision rather than a timing insight.
Frequently asked questions
What is the best time of day to run retargeting ads?
For most local contractors, no particular time. The audience is too small for hourly patterns to be meaningful, and restricting hours mainly limits delivery.
How long should someone stay in my retargeting audience?
As long as the decision takes. Hours for emergency work, days for repairs, weeks for replacements. A single thirty-day window across everything is too long for most of your traffic.
Should I split my audience by how recently they visited?
Only if it is large enough to survive being divided. Two audiences too small to deliver are worse than one that works.
What is the best-timed retargeting a contractor can do?
Reaching past customers when a service is actually due. You know that date and the platform does not, and it converts better than anything aimed at a stranger.
Where to start
Check whether every retargeting audience you run shares one window. If your emergency traffic and your replacement traffic are both sitting in a thirty-day list, separating those two is the highest-value timing change available to you.
