My current GA4 + GTM implementation is producing unreliable numbers and I need a specialist to go through the entire stack, locate the leaks, and leave me with clean, fully-verified data. Scope of work • Audit the existing GA4 and Google Tag Manager containers, then cross-check every tag, trigger and variable against the measurement plan. • Identify why I’m seeing data discrepancies, missing conversions and incorrect event firing across GA4, Google Ads and the Meta Pixel. • Fix each issue, optimise the tagging strategy and, where useful, implement server-side or CAPI improvements for Meta. • Re-confirm that Google Ads conversion actions are mapped correctly to GA4 events, with consistent attribution. • Validate everything in real time with Tag Assistant (and DebugView where helpful) so the numbers line up before you hand the project back. Acceptance is simple: events fire once and only once, totals match between platforms, and the debug tools show zero warnings. Please include a portfolio link or screenshots of similar audits you have completed—proposals without relevant examples won’t be considered.
