A 10-minute trust test.
Five questions you ask Claude and check in GA4, from totals to a calculation, with a score that says whether to trust it day to day, double-check it or hold off.
Where the setup breaks.
Withheld rows, the "(other)" row, sampling, data that keeps changing for 24 to 48 hours and attribution that won't match your ad platforms, plus the limits every do-it-yourself setup shares.

Who it's for, and who it's not for

A small business owner at a kitchen table types a question about their website traffic into an AI chat on a laptop.

Who it's for

Online shop owners on Shopify, WooCommerce, Magento, PrestaShop, OpenCart or Shopware who run Google or Meta ads and want faster answers from GA4 that they can check.
Lead-gen businesses that collect enquiries through forms, calls or bookings, run ads, and want to know which channels actually bring the leads.
Agencies and freelancers who run GA4 and ads for clients and want quick answers from Claude that they can check against GA4 themselves.

Who it's not for

Analysts who already pipe GA4 into BigQuery and query it with their own tools. You'll know most of what's in here.
Anyone without at least Viewer access to the GA4 property, since the setup and the trust test both read from it.

Honest note

The guide can't see your setup. The trust test checks that Claude reads GA4 correctly. GA4 itself can still miss a share of your orders or leads with no warning, through consent choices, ad blockers or a tag that stopped firing. Only a comparison with your store's real orders, or the leads you actually received, shows that. Setup times are our estimates, and Google's own server is a job for a developer.
