The moment it breaks down: an analyst is presenting traffic numbers from a non-GA tool to a client who also has GA running, and the session counts, referral sources, and conversion figures don't match — sometimes by 20–40%. Nobody can explain which number is right, and the meeting derails into a conversation about data credibility instead of decisions.

This gap persists because the analytics vendors have no incentive to surface discrepancies with GA. Their business model depends on you trusting their numbers, not GA's. Building cross-tool reconciliation inside their product would be an admission that their data model differs — which it does, fundamentally, because session definitions, attribution windows, and bot filtering rules differ across every major tool. The vendors won't fix this. GA won't either, because they're the reference standard and have nothing to gain.

What users actually complain about: 'clients usually use this and Google Analytics and the two don't match up.' That's not a configuration problem. Session definitions differ, referral data drops in non-GA tools ('missing Google referral data, which is where the large majority of our search traffic comes from'), and there's no shared schema to compare against. Analysts currently reconcile this manually in spreadsheets, line by line, metric by metric — if they do it at all.

This is a business because the reconciliation need recurs every reporting cycle — weekly, monthly, quarterly — for every client running dual-tool setups. Agencies with 10 clients run this exercise 10 times per month. Without automation, a senior analyst spends 2–4 hours per client per month on something that produces no insight, only credibility maintenance. The cost is real and it compounds.

What to build

Build a reporting layer that pulls session, referral, and conversion data from GA and one or more secondary analytics tools via their respective APIs, maps them to a normalized schema, and produces a side-by-side discrepancy report that flags where definitions diverge and explains the likely cause of each gap — exportable to PDF or CSV for client delivery.

Where to start

Start with Adobe Analytics plus GA reconciliation specifically, because Adobe shops are the most likely to run both tools simultaneously with enterprise budgets and the highest tolerance for paying for reporting infrastructure.

The hard part

The hardest part is building a schema-normalization layer that is accurate enough that clients trust it — if your reconciliation report itself contains errors, you've made the credibility problem worse, not better, and you lose the customer immediately.

How it makes money

Per-client-account monthly fee charged to the agency, starting around $49–99 per connected client property pair, with volume discounts above 10 accounts.
