Before paying for an AI analytics platform, check what the free tool you probably already run does. This note covers Google Analytics 4 (GA4) only, so it stays within what Google documents. For the broader topic, see AI-driven analytics for local businesses.

What GA4's built-in intelligence does

Google describes Analytics Intelligence as machine learning plus conditions you set. Automated insights detect unusual changes or emerging trends and notify you on the Insights dashboard; custom insights let you define conditions and optionally get email alerts, up to 50 per property. Insights are kept for one year and need the Editor or Administrator role to create (Analytics Intelligence).

The retention setting that quietly limits it

Standard properties can keep event data for 2 months or 14 months. The default matters because explorations and funnel reports show no data beyond the retention period, while standard aggregated reports are not affected. Age, gender and interest data is always kept for only 2 months (data retention). If you only look at yearly patterns in explorations, switch to 14 months now.

Decision guide

One location, simple site: use GA4 insights and one custom alert (for example, a drop in booking-button clicks). Add nothing else yet.
You cannot say which channel produces bookings: fix conversion tracking first, see GA4 for small business.
You have point-of-sale or booking data outside the website: the free tool will not see it; that gap is the case for a paid platform.

Worked example (assumption)

A salon sets one custom insight: alert when daily clicks on the booking button fall below a threshold. If the alert fires after a site change, the owner checks the page within a day rather than at month end. The cost is 15 minutes of setup. Compare that with a paid platform quoted at, say, $100 a month: it needs to surface decisions worth more than $1,200 a year to break even.

Frequently Asked Questions

Does GA4 replace Universal Analytics? Yes. Google states GA4 replaced Universal Analytics, whose standard properties stopped processing data on July 1, 2023 (Google).

How long does GA4 keep my data? Standard properties offer 2 or 14 months for event data used in explorations.

Do I need AI analytics software? Only if the questions you have need data GA4 cannot see, such as in-store sales.

Who can create insights? Editor or Administrator roles.
