GA4 Key Events: How to Set Them Up (and Why Conversions Changed Name)

GA4 records many events: page views, scrolls, clicks and form starts. Most are just activity. A few are the reason the website exists, such as an admission enquiry, a call button tap or a purchase. Google Analytics calls those important ones key events^[1].

Google also explains the naming. A key event measures an action that matters to your business in Analytics. A conversion now means an action you use to measure and improve ad campaigns in Google Ads. The flow is simple: event, then key event, then conversion^[2].

Checked on Google Analytics Help on 28 October 2026^[1]:

1. 1
   Open Admin

   Click the gear icon at the bottom left of GA4.

2. 2
   Go to Data display, then Events

   Open the Recent events tab, or search for the event name.

3. 3
   Click the star

   Click the star next to the event, for example form_submit. You need Editor access or above.

4. 4
   No event yet? Create one

   Click Create event, enter a name, turn on Mark as key event, choose a default value and a counting method, then click Create. This needs Marketer access or above.

5. 5
   Check it works

   Fill in your own form. Realtime shows the key event within minutes; standard reports can take up to 24 hours.

• 30 key events per standard property (50 on Analytics 360).
• No back-filling. Marking an event as key only counts from that moment; past data does not change.
• Purchase is marked by default for web and app properties.
• Turning one off does not delete what was already collected.
• Names matter. Google lists recommended event names such as generate_lead; using them keeps reports clean^[4].

Keep the list short. A coaching centre might need only three: enquiry form submitted, WhatsApp button tapped and call button tapped.

Every client asks the same question: what did my money bring in? Without key events, you can only show clicks and visits. With them, you can show enquiries by channel, by campaign and by page. That is how agencies keep clients and how in-house marketers get budgets approved.

Job posts reflect this. On 28 October 2026, Internshala listed 68 jobs asking for Google Analytics skills^[5], including fresher SEO executive and junior web analytics roles. If you run ads, tracking is the first thing to fix; see Google Ads mistakes to avoid.

Say a coaching centre in Mukherjee Nagar runs Google Ads and Instagram posts (a hypothetical example). The owner wants to know which one brings real enquiries.

1. 1
   List the actions

   Enquiry form, WhatsApp tap and call tap. Nothing else.

2. 2
   Check the events

   form_submit comes from enhanced measurement. WhatsApp and call taps are set up as events with Tag Manager.

3. 3
   Mark them as key events

   Star all three in Admin, Data display, Events.

4. 4
   Link Google Ads

   With a linked account, create Google Ads conversions from these key events so bidding learns from real enquiries.

5. 5
   Read the result monthly

   In Reports, compare key events by session source. Use Search Console for beginners for the organic side.

• Local business tracking plan: pick a real shop website, list its 3 key actions and write a one-page plan with event names.
• Before and after report: on your own blog or portfolio site, set up key events and show one month of enquiries by source.
• Ads plus Analytics case: run a small test campaign, mark the lead event as key and show cost per enquiry. Our performance marketing course guide explains this work.

Google has added AI helpers inside Analytics and Ads that suggest insights and changes. Marketers also use AI chat tools to write tracking plans and explain odd numbers. These save time, but they can only read what you track.

What the human still decides: which actions count as real business results, whether a spike is a bug or a real lead and whether a suggested change fits the budget. CABA's courses now teach AI and agentic AI workflows inside the curriculum, with a human check on every output.

GA4 menus change often and every website is set up differently. In a 1-to-1 session, a trainer looks at your own property, finds why a form is not tracking and shows the fix on your screen. Group videos cannot do that.
