GA4 / GTM / Google Ads Configuration Audit

We run a US-based data analytics consultancy. One of our clients is an ecommerce group with several brands, and I need a clear, accurate picture of how analytics and ad tracking are actually configured on each one. This posting covers one brand. The work has two parts. First, document exactly what is configured today — observed facts, not assumptions. Second, tell me what you would change and why, and just as importantly, what you would leave alone and why. I am not asking you to implement anything. Scope for this engagement: GA4: property and stream configuration, data streams, enhanced measurement settings, custom events and parameters, conversion events, audiences, linked products, filters, and any data redaction or referral exclusion settings. GTM: every tag, trigger, and variable in the container, including paused and unpublished items. Note which tags are firing, on what triggers, and flag anything that appears duplicated or orphaned. Google Ads: conversion actions, their source, attribution model, counting method, and which are set as primary. You will deliver this in a template I provide. For the documentation section I want observed facts and screenshots where a setting is ambiguous. If something is unclear or you cannot access it, write "unable to verify" rather than guessing — I would much rather have an honest gap than a confident error. For the recommendations section, list what you would change, ranked by impact, with a sentence on what breaks if it stays as-is. Then list anything that looks wrong but you would leave alone, and explain why. I am specifically interested in that second list. Not every anomaly is a defect, and I want to know whether you can tell the difference. I will supply read-only access to all three platforms. Who this is for: Someone who has audited or documented someone else's analytics setup before, not just built their own. The skill I am paying for is noticing the thing that looks fine but isn't, and knowing when to leave it alone. Working arrangement: Async-first. I am in US Central time and do not expect overlapping hours. I will answer questions in writing, usually within a few hours. I expect you to ask when a spec is unclear rather than assume. Timeline: One week from access being granted.
