Evaluate tracking gaps, tag health, consent, and QA. Quantify reporting loss, prioritize fixes, and keep every conversion trustworthy, week after week.
Use this sample to understand typical ranges and how gaps affect the score.
| Scenario | Sessions | Platform conv. | Analytics conv. | Consent % | Events OK / Total | Audit Score | Primary note |
|---|---|---|---|---|---|---|---|
| Healthy baseline | 80,000 | 1,600 | 1,520 | 92 | 10 / 10 | 90 | Small gap; strong consent and QA. |
| Consent drag | 55,000 | 980 | 780 | 68 | 8 / 9 | 62 | Low consent coverage increases missing events. |
| Broken tagging | 42,000 | 720 | 510 | 80 | 6 / 8 | 48 | Event firing issues and large reporting gap. |
This calculator converts your audit inputs into normalized subscores (0–1), then computes a weighted reliability score (0–100).
A conservative technical risk factor blends observed gap, consent shortfall, adblock estimate, tag health, latency, and deduplication.
These formulas are heuristic audit signals, designed to prioritize fixes. Always validate with diagnostics, server logs, and controlled test conversions.
Teams typically treat 85–100 as reliable instrumentation, 70–84 as usable but risky, 55–69 as unstable, and below 55 as high risk for optimization decisions. In a 30–60 day window, a 10% tracking gap can shift budget allocation by several percentage points when bids and targets are automated. For ecommerce, many audits target less than 5% gap, 95% event coverage, and 90% QA pass rate; those thresholds keep ROAS, CAC, and LTV models aligned across tools. during scaling and quarterly reporting.
The calculator measures the absolute gap and the gap rate between platform-reported conversions and analytics conversions. A 900 vs 810 example produces a 90 conversion gap and a 10% gap rate. The model down-weights reliability when the gap exceeds 25%, because discrepancy at that level usually indicates missing events, dedupe failures, or consent loss.
Event coverage uses validated firing events divided by configured key events. If 7 of 8 events fire correctly, coverage is 87.5%. Tag health adds operational context: “Good” assumes clean releases and low error rates, “Warning” signals drift, and “Broken” suggests missing containers, duplicate tags, or blocked scripts.
Consent coverage affects how much data analytics can collect. The scoring normalizes coverage from 50% (minimum viable) to 100% (ideal). For instance, 85% consent coverage yields a high consent subscore, while 68% materially increases modeled under-reporting and should prompt consent UX testing and regional configuration review.
High p95 latency can push events outside attribution windows or cause drops in real-time validation. The latency subscore treats 500 ms as strong and 2000 ms as weak. Adblock estimate provides an upper-bound headwind; enabling enhanced matching and server-side tracking adds small score bonuses because they improve match rates and reduce client loss.
QA pass rate is the share of tested conversions that fire correctly and match expected identifiers. Testing 40 samples with 34 passes yields 85%. Combine weekly QA, UTM discipline checks, and deduplication verification to stabilize reporting. Export CSV for audits, and use the PDF report as evidence in change management and vendor reviews.
The score is most sensitive to conversion gap rate, event coverage, consent coverage, and QA pass rate. Tag health, latency, UTMs, and deduplication refine the diagnosis and prioritize fixes.
Use the same conversion definition and date range in both systems. Platform conversions can be from ads or CRM imports; analytics conversions should match the on-site event or goal that represents the same outcome.
Consent helps, but gaps can persist from blockers, misfiring tags, cross-domain breaks, attribution settings, or deduplication errors. Reconcile IDs, timestamps, and event payloads across tools to isolate the cause.
Aim for at least 30–50 end-to-end test conversions per month across key funnels. Include different devices, browsers, and regions. Increase samples after releases, consent changes, or when gaps widen.
Server-side tracking reduces client-side loss from blockers and improves reliability under slow networks. It can also simplify deduplication when event IDs are consistent. The calculator awards a modest bonus, not a guarantee.
Yes. Replace AOV with average lead value and margin with expected contribution. Keep the conversion definition consistent, validate form submission and CRM handoff events, and treat cross-domain and consent checks as equally important.
If your score is below 70, prioritize fixing firing and consent first. Then improve deduplication, UTMs, and latency.
