Click-by-click steps for adding a GA4 app, including developer mode or the newer Plugins menu for apps added by URL, plus a boxed section on Google's own server for whoever implements it.
15 prompts, labelled by trust.
Shop prompts on purchases and revenue, lead-gen prompts on form submissions and lead share, each marked SAFE, VERIFY or WON'T WORK WITHOUT JOINED DATA and written to name your app.
A 10-minute trust test.
Five questions you ask ChatGPT and check in GA4, from totals to a calculation, scored so you know whether to trust its GA4 answers, double-check them or fix the setup first.
ChatGPT's own blind spots.
Memory that carries old figures into new answers, a quiet switch to another model at thinking limits and long tool responses that can be cut short, alongside GA4's thresholding, sampling and "(other)" row.

An AI skill for Claude, ChatGPT, Gemini or Copilot

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 in the chat they already use.
Lead-gen businesses that collect enquiries through forms, calls or bookings, run ads, and want ChatGPT to tell them which channels actually bring the leads.
Agencies and freelancers who run GA4 and ads for clients and want quick answers in ChatGPT 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, and ChatGPT's menus have moved twice in a year, so a label may have changed by the time you read it. Apps added by URL need developer mode, which OpenAI doesn't list for Free accounts, or the newer Plugins menu if your account shows it. The trust test checks that ChatGPT reads GA4 correctly. Whether GA4 caught every order or lead takes a comparison with your store's real orders, or the leads you actually received.
