Also goes by Conversion measurement, Key event tracking [![Siite](/images/layout/logo.svg)Written by Siite](/about/)Updated September 8, 2026 ## Entry contents [All Terms A to Z←Browse the full dictionary](/dictionary/) Conversion tracking is the plumbing between what somebody did and where they came from. A tag fires when a form is submitted, a tracked number records a call over a set length, or your CRM reports back that a lead turned into a job. Without it, every decision about budget is made on the strength of a feeling. > **Briefly explained** > > - It connects an action to the source that produced it. > - For most local businesses, calls are the majority of conversions. > - Broken tracking does not give you no answer. It gives you a wrong one. > - It breaks silently, which is why it needs checking on a schedule. ## What needs to be measured? Everything a customer might do to reach you, not just the convenient one. - **Calls**, with a minimum duration so hang-ups do not count - **Forms**, confirmed by the page that actually loads after submission - **Chats and messages**, including the ones from your profile - **Booked jobs**, fed back from the CRM so the platform optimizes toward work rather than toward inquiries ## Why do calls matter more than forms? Because for most local businesses, the phone is where the money arrives. A site measuring only form fills is reporting on a minority of its leads, and usually the less urgent minority. The practical consequence is worse than a gap in a report. Ad platforms optimize toward what they can see. Feed them only forms, and they will quietly find you more people who fill in forms and fewer people who call. ## Where do setups quietly fail? The same handful of failures turns up again and again. - A thank-you page tag that stopped firing after a site rebuild - Calls counted at one second, so wrong numbers look like leads - Duplicate tags counting the same lead two or three times - A consent banner that blocks the tag before it loads - Browser restrictions dropping conversions that never reach the platform None of these announce themselves. The report simply gets quieter, or louder, and the budget follows it. ## What does good look like? - Calls, forms and chats all measured, with a sensible call duration - Offline outcomes sent back from the CRM, so the platform learns from booked jobs rather than raw leads - One definition of a conversion, written down, used everywhere - Server-side where the browser is unreliable - A quarterly check that every one of them still fires ## What do the terms mean? - **Conversion:** The action you decided to count. - **Key event:** What [GA4](/dictionary/google-analytics-4/) calls the same thing. - **Attribution window:** How long after a click a conversion still counts. See [attribution model](/dictionary/attribution-model/). - **Offline conversion import:** Sending CRM outcomes back to the ad platform. - **Server-side tracking:** Conversions sent from your server rather than the visitor’s browser. Owner questions ## What owners ask us about Conversion Tracking ### Why do Google Ads and my CRM disagree? +Different windows, different definitions and different visibility. Ads counts a conversion inside its attribution window. Your CRM counts a job when it closes. Pick one as the book of record. ### Do I need call tracking? +If most of your leads arrive by phone, yes. Without it, every channel that produces calls looks like it produces nothing, and the budget drifts to whatever happens to be measurable. ### What is server-side tracking? +Sending conversion data from your own server or CRM rather than from the browser. It survives the ad blockers and browser restrictions that increasingly break tag-based tracking. ### How long should a call be before it counts? +Long enough to exclude hang-ups and wrong numbers. Sixty seconds is a common starting point. Set it once, write it down, and keep it stable so the numbers stay comparable. ### How often does tracking break? +More often than anyone expects, and always silently. A site rebuild, a new form plugin or a consent banner change can stop it overnight without a single alert.Put this to work ## Guides that use this Step-by-step playbooks from the team, written for owners doing the work themselves.
