GA4 attribution for B2B websites: what to track before scaling ads

1. Track qualified lead signals, not just form submits

A submitted form is not always a qualified lead. Track fields like budget range, timeline and service intent as event parameters.

This gives context for channel quality and helps prioritize real opportunities.

• Event: `contact_form_intent_submit` with qualification parameters.
• Capture UTM, gclid, fbclid and landing page source.
• Store language and service type to compare markets.

2. Build a decision dashboard around funnel stages

Split reporting into visits, qualified submissions and closed deals. This prevents over-optimizing for cheap low-intent traffic.

Use one view per market and one combined view for management decisions.

3. Validate attribution monthly

Review top channels, branded vs non-branded queries and assisted conversions. Tune campaigns and landing pages accordingly.
