Google Analytics 4 for Beginners: What to Track on Your Business Website

Set GA4 event data retention to 14 months on day one (the only other option is 2 months), mark your enquiry actions as key events, then watch five things: users, traffic sources, top pages, conversion rate and devices.

Google Analytics 4 is installed on your website. Now what? Most business owners either ignore it completely or get overwhelmed by data that doesn’t matter. Here’s what to actually pay attention to.

What should I set up in GA4 first?

Two settings. First, under Admin, Data Settings, Data Retention, change event data retention from 2 months to 14 months. It does not change your standard reports, but explorations and funnel reports can only look back as far as this setting allows. Second, mark the actions that matter to your business, such as form submissions and phone clicks, as key events.

What is a key event in GA4?

Key events are GA4’s name for actions that matter to the success of your business, such as an enquiry or a purchase. Any event you collect can be marked as one. The word “conversion” is now kept for actions used to measure and optimise ad campaigns.

The Metrics That Matter

Users and Sessions

How many people visit your site and how often. Look at the trend over time rather than absolute numbers. Consistent growth means your marketing is working.

Traffic Sources

Where your visitors come from: organic search (Google), direct (typed your URL), social media, referral (links from other sites), or paid advertising. This tells you which channels are driving results.

Top Pages

Which pages get the most visits. If your pricing page is your most viewed page, people are interested in buying. If your homepage has the highest bounce rate, something isn’t working.

Conversion Rate

The percentage of visitors who take your desired action, filling in a contact form, making a purchase, calling you. This is the single most important metric for measuring your website’s effectiveness.

Device Breakdown

What percentage of your traffic is mobile vs desktop. If 70% of your visitors are on mobile but your conversion rate is 3x higher on desktop, your mobile experience needs work.

Setting Up Conversions

GA4 calls these “key events.” You need to define what counts as a conversion for your business:

  • Contact form submission
  • Phone number click
  • Email link click
  • Purchase completion
  • Download of a resource

Without conversion tracking, you’re measuring traffic but not results.

How Often to Check

Weekly glance at traffic trends and conversions. Monthly deep dive into sources, top pages, and device performance. Quarterly strategy review to adjust based on what’s working.

We set up GA4 with proper conversion tracking on every site we build. It’s included in every package.

Frequently asked questions

How long does GA4 keep my data?

14 months at most on a standard property, and only if you choose it; the other option is 2 months. Age, gender and interest data is always kept for 2 months. The setting only affects explorations and funnel reports, not standard aggregated reports.

Are key events the same as conversions in GA4?

No, not quite. Key events are actions that matter to your business, such as a form submission. Conversions now refer to actions used to measure and optimise ad campaigns.

Can any event be a key event?

Yes. Any event you collect can be marked as a key event, so create or identify an event that records the action, such as a contact form submission or phone click, then mark it.

Do I need to check GA4 every day?

No. A weekly glance at traffic and key events, a monthly look at sources, top pages and devices, and a quarterly strategy review are enough for most business websites.

Is GA4 set up on sites Hire The Creatives builds?

Yes. GA4 with key events for your enquiry actions is included in every package, from £495 for a 1 to 5 page site.
