GA4 Features That Give Businesses Actionable Insights

Google Analytics 4 has moved a long way from the tool most site owners grudgingly migrated to when Universal Analytics shut down on 1 July 2024. The property you log into in 2026 has a Gemini-backed assistant, automated anomaly summaries on the home page, a dedicated channel for traffic from ChatGPT and Claude, and a budgeting workspace that did not exist two years ago. The catch is that almost none of it is useful until the property is configured properly, and most WordPress sites we audit are still running the default setup from the day the tag was pasted in.

This guide walks through the GA4 features that actually change decisions for a business, in the order we would switch them on, with the menu paths and settings you need. The original version of this post covered Google’s mid-2024 announcement (AI insights, cross-channel tracking, budgeting tools and Privacy Sandbox support). Most of those have since shipped, so we have rewritten it around what is live today.

Start with key events, not reports

Everything interesting in GA4 (predictive audiences, the Advisor, attribution reports, budget projections) is built on top of key events. If you have not defined any, the AI features have nothing to reason about. Google renamed “conversions” to “key events” in March 2024 so that the word “conversion” could be reserved for Google Ads, which is why the two numbers never matched before.

For a typical WordPress business site we mark three to five events as key events, no more:

• generate_lead for a contact or quote form submission.
• purchase for WooCommerce or Easy Digital Downloads orders.
• sign_up for a membership or community registration (BuddyPress, BuddyNext, LearnDash).
• file_download or click on a specific outbound link where that is the real goal.

To mark one, go to Admin → Data display → Events, find the event and toggle Mark as key event. If the event does not exist yet, create it at Admin → Data display → Events → Create event using a condition such as page_location contains /thank-you/. That is the lowest-effort way to capture form submissions on WordPress without touching theme code. If you use WPForms, Gravity Forms or Fluent Forms, each has a native GA4 event option that is cleaner than the thank-you page trick.

Leave the counting method on “once per event” for purchases and “once per session” for leads. Double-counted leads are the most common reason a client tells us “GA4 says we get 40 enquiries a month and we get 12.”

Generated insights and the Analytics Advisor

This is the headline change since 2024. The Analytics Advisor, a conversational assistant running on Gemini, reached general availability for English-language Standard and 360 properties in December 2025. In February 2026 Google added generated insights to the Home page: a short, plain-language summary of the three biggest changes since you last logged in, including anomalies, configuration changes and new traffic sources.

In practice the Advisor is good at three things and mediocre at a fourth:

1. Explaining spikes and drops. Ask “why did sessions from organic search fall last week?” and it breaks the change down by landing page, country and device. This used to take ten minutes of Explorations work.
2. Building a report you would otherwise have to construct. “Show me purchase revenue by first user source for the last 90 days” returns a table and a link to the saved exploration.
3. Flagging configuration mistakes. Since April 2026 the related Task Assistant lists tailored recommendations (unlinked Search Console, missing key events, duplicate page_view events) under categories. Work through it once; it catches things audits miss.
4. Strategy. It will happily tell you to “invest more in paid social” based on six conversions. Treat those suggestions as prompts to check, not conclusions.

You open the Advisor from the sparkle icon at the top right of any report. It needs the property to have at least a few weeks of data and at least one key event before its answers stop being generic.

Predictive metrics

The older AI features still matter. Once a property records roughly 1,000 purchasers and 1,000 non-purchasers in a 28-day window, GA4 switches on purchase probability, churn probability and predicted revenue. You use them at Admin → Audiences → New audience → Predictive, where Google suggests audiences such as “likely 7-day purchasers”. Most small WooCommerce stores never reach the threshold. Larger stores and membership sites with frequent logins do, and remarketing to “likely to churn” members is one of the few GA4 features that pays for itself in a month.

Tracking the channels that did not exist in 2024

AI assistant traffic

From 13 May 2026, GA4 classifies visits referred by ChatGPT, Gemini, Claude, Perplexity and similar tools into a dedicated AI Assistant default channel, with the medium set to ai-assistant. Before that date those visits were scattered across Referral and Direct, which is why so many sites believed AI sent them nothing.

To see it, open Reports → Acquisition → Traffic acquisition and change the primary dimension to Session default channel group. For content sites we look after, AI Assistant is typically 1 to 4 percent of sessions in mid-2026 but converts at two to three times the rate of organic search, because the visitor arrives with a specific question already answered. If you publish an llms.txt file or structured FAQ content, this is the report that tells you whether it is working.

Source groups and non-Google campaign data

The 2024 announcement promised better cross-channel visibility. Two pieces of that shipped in 2026. The Source Group dimension (June 2026) rolls up variants such as facebook, m.facebook.com and instagram into a single value so paid social reporting stops fragmenting. And campaign data import lets you upload cost, clicks and impressions from Meta, Pinterest, Reddit or LinkedIn so the Advertising workspace can compute cost per key event across every channel, not only Google Ads. Since 28 July 2026 the upload requires a currency field, and a validation report (August 2026) shows you which rows were rejected and why.

The import lives at Admin → Data collection and modification → Data import → Create data source → Cost data. Use consistent UTM parameters on the ad side (utm_source=facebook&utm_medium=paid-social&utm_campaign=...) or the join will fail silently and you will see cost without conversions.

Planning and budgeting inside GA4

Cross-channel budgeting launched in beta in February 2026 and sits under Advertising → Planning. You enter a total budget and a target (revenue or key events), and GA4 projects outcomes per channel from your historical data, then lets you drag allocations around to see the predicted effect. A companion projections report tracks pacing against the plan during the month.

Our honest read: it is useful for businesses spending more than a few thousand a month across at least three channels with imported cost data. Below that, the projections are too noisy and you are better off with a spreadsheet. It is also only as good as your key event setup, which brings us back to the first section.

The Conversion attribution analysis report (beta, January 2026) is more broadly useful. It shows assisted conversions by channel, which is the number you need when someone asks why organic content “doesn’t convert” while last-click reports hide its role in the first touch.

Privacy-first measurement that actually works

The 2024 post talked about Privacy Sandbox APIs replacing third-party cookies. Google then reversed course in 2025 and kept third-party cookies in Chrome, so that part aged badly. What did stick is the rest of the privacy stack, and it matters for any site serving EU, UK or California visitors.

Feature	What it does	Where to set it
Consent Mode v2	Sends cookieless pings when a visitor declines, so GA4 can model the missing conversions	Your consent banner plugin (Complianz, CookieYes, Real Cookie Banner) plus Admin → Data collection → Consent settings
Enhanced conversions	Hashes first-party data (email) at purchase to improve Ads attribution	Admin → Data collection → User-provided data collection
Data retention	Default is 2 months for event data; change to 14	Admin → Data collection and modification → Data retention
Hostname filter	Drops events from domains that are not yours (staging, scrapers)	Admin → Data filters (added June 2026)
Google signals	Cross-device reporting; turn off if you do not run Ads and want fewer threshold gaps	Admin → Data collection → Google signals

The data retention setting is the one everybody forgets. At the default of two months, any exploration older than that returns nothing, and you cannot recover it. Change it on day one.

For WordPress specifically, Site Kit by Google handles the tag and Consent Mode wiring with most major banner plugins. If you use a caching or optimisation plugin that delays scripts, exclude the GA4 and consent scripts from the delay or your consent state will arrive after the first page_view fires.

A worked example: a LearnDash course site

A client selling online courses with LearnDash and WooCommerce came to us with GA4 “installed” and unused. Here is what the setup looked like after half a day of work:

1. Key events: purchase (WooCommerce, via Site Kit’s ecommerce integration), sign_up (free account), and a custom course_enrolled event fired with a small snippet on the LearnDash enrolment hook.
2. Data retention to 14 months; hostname filter excluding the staging domain; Search Console linked.
3. Cost data import from Meta Ads, with UTMs standardised across every ad.
4. A predictive audience, “likely 7-day purchasers”, exported to Google Ads for remarketing once the threshold was met about six weeks later.

The first generated insight on the Home page, two weeks in, pointed out that the AI Assistant channel had a 9 percent sign-up rate against 2 percent for organic. That led to rewriting the free-lesson pages as direct answers to the questions people were asking chatbots. None of that required a report nobody would read; it required three key events and one filter.

Frequently asked questions

Is GA4 still free?

Yes. The Standard property is free. GA4 360 is the paid tier for very high event volumes and unsampled data, and it starts well into five figures a year. Almost every WordPress site belongs on Standard.

Can I still get my Universal Analytics data?

No. Access to UA properties and their data ended on 1 July 2024. If you did not export it, it is gone. The only historical comparisons now available are within GA4.

Does the Analytics Advisor send my data to Gemini for training?

Google states the Advisor works within your Analytics property and is covered by the Analytics terms, not consumer Gemini terms. Review the data processing terms under Admin → Account settings if you have regulatory obligations, and remember that GA4 must not receive personally identifiable information in any event parameter regardless.

What is the difference between GA4 and a WordPress analytics plugin?

Plugins such as MonsterInsights or ExactMetrics are front-ends for GA4 inside wp-admin; they do not collect anything themselves. Privacy-focused alternatives (Plausible, Matomo, Burst) do collect their own data and skip the consent banner in many jurisdictions, at the cost of losing the Ads integration and predictive features. We compared the options in our roundup of analytics plugins for WordPress.

Where to start

If you do nothing else this week: define your key events, set data retention to 14 months, add a hostname filter, link Search Console, and open the Task Assistant to clear its recommendations. Then check the AI Assistant channel in Traffic acquisition, because it is probably already sending you better visitors than you think.

The full change log, including the items referenced above with dates, is on Google’s What’s new in Google Analytics page, which is worth a monthly skim. If your store or community needs custom event tracking wired into WooCommerce, LearnDash or BuddyPress hooks, that is the kind of work our WordPress development team does regularly, and it rarely takes more than a day.
