Common failures

Installing the tool before deciding the questions. This is the original sin: the setup starts with "let's add GA4" instead of "what decisions do we need to make". It happens because installing a tool feels like progress, while writing a measurement plan feels like delay. Avoid it by writing the plan first, on paper, and only then choosing tools to serve it. The plan is the work; the tool is the easy part.

Inconsistent event and parameter naming. "signup", "Sign Up" and "user_registered" all describing the same action, captured over months by different people in the moment. It happens because nobody agreed a convention up front, so every event is named to taste. The result is funnel reports that quietly lie. Avoid it by locking one naming convention into the measurement plan and auditing against it before anything ships.

Browser-only conversion tracking. Relying on a client-side pixel for your most important event, the purchase or activation, so ad blockers, privacy settings and dropped sessions silently eat a chunk of your conversions. It happens because browser tracking is the default and the easiest to set up. The fix is to fire revenue events server-side from your backend when the money actually moves, and treat that as the canonical number.

Running redundant tools that disagree. Two web analytics tools, two attribution sources, and a weekly argument about which figure is real. It happens because each tool was added by a different person to solve a different problem, and none was retired. Avoid it by naming one canonical tool per question and making everything else feed or defer to it, never compete with it.

Bolting consent on at the end. The tracking is built to fire on page load, then a consent banner is added two days before launch and either breaks everything or is quietly ignored. It happens because consent is treated as legal paperwork rather than part of the architecture. Avoid it by wiring consent and Consent Mode in from the first tag, so the whole setup assumes consent as a gate from day one.

Set-and-forget. Tracking goes live, the project is marked done, and nobody owns it. A redesign breaks a tag, a campaign adds untracked links, and the data rots while everyone keeps trusting it. It happens because analytics is treated as a one-off install instead of a living system. Avoid it by assigning an owner and running a standing monthly check that the key events still fire with the right values.
