Create your GA4 property, install the tag, configure conversions, and build your first custom report in under 30 minutes.
Step 1: Create Your GA4 Property
Go to analytics.google.com and click “Admin” in the bottom-left. Under the Property column, click “Create Property.” Name it after your business, select your time zone and currency, then choose your industry category and business size. GA4 will create a data stream for you — select “Web” and enter your website URL.
Step 2: Install the Tracking Tag
You have two options: install the gtag.js snippet directly in your site’s <head>, or use Google Tag Manager (recommended). With GTM, create a new tag using the “Google Analytics: GA4 Configuration” template, paste your Measurement ID (starts with G-), and set it to fire on all pages. GTM gives you more flexibility to add custom events later without touching your site’s code.
Step 3: Configure Events and Conversions
GA4 automatically tracks page views, scrolls, outbound clicks, site search, and file downloads. For business-critical actions (form submissions, phone calls, purchases), you’ll need to set up custom events. In GTM, create a trigger for each action and a corresponding GA4 Event tag. Then in GA4, go to Admin > Events and mark your key events as conversions.
Step 4: Build Custom Reports
GA4’s Explore section lets you build custom reports that answer specific business questions. Start with a Free Form exploration: add dimensions (traffic source, landing page, device) and metrics (sessions, conversions, revenue) to build the exact report you need. Save explorations you use frequently — they’re much more flexible than the standard reports.
Step 5: Link Google Ads and Search Console
In GA4 Admin, link your Google Ads account under Product Links. This imports cost data and lets you see GA4 audiences in your ad campaigns. Similarly, link Google Search Console to see which search queries drive traffic to your site. These integrations give you a complete picture of how users find and interact with your business.
Common GA4 Setup Mistakes
The biggest mistake is not verifying your tracking is working. Use GA4’s Realtime report and the Tag Assistant Chrome extension to confirm tags fire correctly. Other common issues: forgetting to filter out internal traffic, not setting up cross-domain tracking if you have multiple domains, and relying on default channel groupings that misattribute traffic. Test everything before you start making decisions based on the data.
