For saas
AtriTap generates the tracking foundation SaaS companies actually need: sign_up and start_trial events, plan dimensions, and attribution rules that feed CAC and trial-to-paid analysis. Works with any frontend and any auth provider.
Google Ads imports start_trial or sign_up as the optimisation event, depending on your funnel. Meta fires CompleteRegistration. TikTok fires CompleteRegistration.
Trial-to-Paid conversion rate for SaaS with free trials; Cost per Sign-up for PLG businesses.
If your funnel has a meaningful trial step and the conversion window is tight, start_trial is a better optimisation target. If sign-ups correlate reliably with paid conversion, sign_up is fine.
Use the user.signup_method dimension to separate them. The generated GA4 custom dimension registry handles this automatically.
Those live in your product analytics tool, not GA4. AtriTap focuses on the marketing-facing side of the funnel for now.
