Attribution window

The clock that starts at the first click

Every ad platform and every analytics tool has to settle one question before it can report anything: how long after a click does a sale still count? The attribution window is that answer, written as a number of days.

Say a homeowner searches for gutter cleaning on a Tuesday, clicks your ad, reads two pages, and closes the tab without calling. Three weeks later a storm rolls through, she remembers the name, and picks up the phone. If the window is set to a month, that call is credited to the ad. If the window is set to a week, the same call appears in your reports as though it came out of nowhere.

Nothing about the customer changed. She was always going to call. Only the bookkeeping rule changed, and with it the story your report tells about which half of your budget is working.

Most platforms also keep a second, looser window for people who saw an ad and never clicked it. Same mechanic, weaker standard of proof, and worth knowing about before you compare one report against another.

Slow jobs and emergency jobs need different windows

The right length depends on how people actually buy from you. An emergency plumber usually gets the call within the hour, so a short window captures nearly all of it. A roofer, a remodeler, or a dock builder gets the click in March and the signed contract in June, and a short window quietly throws that job away.

That gap has a real cost. When your reports only credit the fast conversions, the campaigns aimed at bigger, slower work look like the losers, and the natural reaction is to switch them off. You end up cutting the spend that was doing the patient part of the job.

The answer is not a longer window for its own sake. It is choosing a window that matches how long your customers actually take to decide, then leaving it alone long enough that two months can be compared honestly. We are Orlando based and have worked with local service businesses nationwide since 2008, and a mismatched window is a common reason two reports about the same month disagree. Setting that up alongside the campaigns themselves is part of what our Google Ads management covers.

It moves your cost numbers, not your revenue

Widen the window and your credited conversions go up, which drags your cost per acquisition down and pushes your return on ad spend up. Your bank balance does not move an inch. That is also why changing the setting in the middle of a quarter ruins your trend lines: you are measuring two stretches of time with two different rulers.

It explains most of the mismatch between tools, too. Your ad account and your analytics account can each apply their own window to the same set of visits and land on different totals, both of them correct by their own rule. Neither one is lying to you, and there is no version of this where the two totals agree.

Pick a window, write down the date if you ever change it, and read the credited number as one view of what happened rather than the final word on it.
