Form Submit Event Tracking -- Google Ads, GA4 & Meta

Looking for someone to audit and fix conversion tracking across three platforms for a lead gen website. The goal is one consistent, validated form submit event firing correctly across Google Ads, GA4 and Meta -- not just a GA4 setup, but clean cross-platform attribution that a paid media manager can actually rely on. Scope: - Audit current event setup across Google Ads, Google Tag Manager, GA4 and Meta - Identify what's firing, what's wrong, and what's double-counting - Implement a single validated form submit trigger via GTM as the source of truth - Import correctly into Google Ads and dedupe against Meta - Ensure GA4 key events reflect actual conversions, not form starts or page views - Validate end-to-end with a test submission This is a paid media problem, not just a tagging job. The person I'm looking for understands why consistent attribution matters across platforms and can set it up accordingly across paid platforms. Access: GTM, GA4, Google Ads and Meta Business Manager provided. For this initial job you'll work under an existing user login -- you'll need to be comfortable coordinating 2FA and working discreetly within a client environment. If the fit is right, we'll set up your own access from there. Fixed price, fast turnaround. Ongoing work available for the right person.
