Every event, verified against reality
Purchases, signups, and key events checked for existence, single firing, and correct values, compared against the numbers in your store or CRM rather than taken on faith.
GA4 audit
GA4 audit: do your numbers add up?
Scan your site free and see whether Google Analytics is telling the truth: events missing or firing twice, conversions dropped by consent settings, and attribution quietly going to the wrong channel.
A GA4 audit that ends in working analytics: Mimetic finds the broken events and ships the corrected setup as a change you review.

After we fixed their checkout and cleaned up conversion tracking that was overcounting 10x, monthly purchases rose 48%.
EXAMPLE FINDING
High impact
Purchases fire twice, so every number downstream is wrong
The purchase event fires from both the theme and a tracking app, so GA4 reports nearly double the real order count. Revenue per channel, ROAS, and every experiment result inherit the error.

Your analytics is only useful if it is telling the truth.
The most common GA4 problem is not a missing report, it is silent disagreement: Shopify Admin says sales are up while GA4 shows a completely different story, and nobody knows which number to trust. The causes are mechanical and findable: events installed twice, conversions dropping before they ever hit the tag, consent settings silently discarding sessions, and redirects stripping the attribution off every campaign click. A GA4 audit checks each of them against reality, then fixes what it finds.
The silent losses, found
Consent mode misconfiguration, ad blockers, cross-domain breaks, and redirect chains that strip campaign parameters, the leaks that make real conversions vanish or arrive labeled as direct traffic.
Fixed, not just flagged
The audit output is not a findings PDF. Mimetic repairs the tagging and configuration and ships the change for your review, so the next week of data is data you can use.
Frequently asked questions
What does a GA4 audit check?
Property and data-stream configuration, tag installation on every important page, event integrity (each key event exists, fires exactly once, and carries correct values), conversion definitions, consent mode behavior, cross-domain tracking, channel attribution, and whether GA4 totals reconcile with your store or CRM. That reconciliation is the single most revealing check.
Why does GA4 not match my Shopify numbers?
Some gap is structural: GA4 loses ad-blocked and consent-declined sessions, and the two systems attribute and timestamp orders differently, so 5 to 15 percent is normal. Gaps beyond that usually mean duplicate purchase events, a checkout tracking gap, or consent mode discarding conversions. An audit tells you which, and how much of your gap is fixable.
Is there a GA4 audit checklist?
Yes, and the categories are consistent: installation coverage, event and conversion integrity, deduplication, consent behavior, cross-domain setup, attribution, and reconciliation against source-of-truth revenue. The scan runs that checklist against your live site automatically, which is faster and less error-prone than clicking through it by hand.
How much does a Google Analytics audit cost?
Analytics agencies typically charge $1,000 to $5,000 for an audit document. Mimetic runs the audit free, and if your GA4 is broken or missing it can repair or set up the property and tagging as changes you review. Continuous monitoring is $199/mo per site.
