Google Analytics 4 vs Microsoft Clarity (2026): Which Wins?

Both tools are free. Both belong on your website. But if you can only invest time in learning one, Google Analytics 4 wins — it tells you what's happening across your entire business, not just on a single page. That said, if you're losing customers somewhere in your checkout flow and can't figure out why, Clarity will show you exactly where they're giving up.

Our Pick: Google Analytics 4
Why: It connects traffic sources, conversion data, and revenue into a single picture that actually helps you make decisions.
Choose Microsoft Clarity if: You already have analytics in place and need to see how people are behaving on your pages, not just how many showed up.

Quick Comparison

Where Google Analytics 4 Wins

Traffic attribution you can act on. GA4 tells you which channels — paid search, organic, email, social — are driving not just visits but conversions. That distinction matters when you're deciding where to spend your next £500 in advertising. Clarity tracks what happens on the page; GA4 tells you how the person got there and whether they ever came back.

Conversion tracking with real business depth. You can set up goal funnels, track ecommerce transactions, and measure micro-conversions like form starts and video plays — all without paying. For a small retail or services business, this separates guessing from knowing. Once configured correctly, the conversion reports alone justify the setup time.

AI-driven anomaly detection that surfaces things you'd miss. GA4 flags unusual spikes or drops in traffic before you'd normally notice them. If a key landing page suddenly falls off a cliff on a Tuesday afternoon, you want to know that day — not when your sales pipeline dries up three weeks later. No competing free tool does this as reliably.

Where Microsoft Clarity Wins

Session recordings that are genuinely useful. Clarity records real user sessions and lets you filter them by device, location, or behaviour — including users who rage-clicked or got stuck. Watching five minutes of recordings on your checkout page will teach you more about your customers' frustrations than a month of reading bounce rate data.

Heatmaps and scroll maps with zero configuration required. Clarity starts building click maps and scroll depth data the moment you install the tracking snippet. There's no goal-setting, no event configuration, no tagging taxonomy to argue about. You add the code and it works. For time-poor business owners, that matters.

It integrates with GA4 rather than competing with it. Clarity has a native Google Analytics integration that links session recordings directly to your GA4 data. When you see a high-exit page in GA4, you can jump straight into Clarity recordings of those exact sessions. That's clever, and it's why both tools belong on every serious website simultaneously.

Pricing: What You Actually Pay

Both tools are free, and neither has a paid tier in the conventional sense. There's no premium upgrade where Clarity unlocks heatmaps — you get everything from day one. GA4 sits alongside Google Analytics 360, which is an enterprise product aimed at large organisations with budgets to match, but that's irrelevant here.

At £0/month, Google Analytics 4 is the stronger standalone investment of your time, simply because it covers more ground. At £0/month, Clarity is the smarter complement — you're not paying to fill a gap that GA4 leaves, you're adding a dimension it doesn't have. Running both together costs nothing except the hour it takes to connect them.

Who Should Choose Google Analytics 4

• If you run any kind of paid advertising and need to track which campaigns are actually converting, GA4 is non-negotiable.
• If you're a content-driven business measuring which articles bring in leads, the traffic source reports will become your most-checked dashboard.
• If you sell online and want to see your full revenue funnel — sessions, product views, add-to-carts, purchases — in one place, GA4 handles this better than anything else at this price.
• If you want to understand trends over time, compare month-on-month performance, and spot seasonal patterns in your audience, Clarity simply doesn't offer this.
• If your business is growing and you anticipate needing deeper data integrations down the line, GA4's connections to the broader Google ecosystem give you room to scale.

Who Should Choose Microsoft Clarity

• If you've rebuilt your homepage three times and still aren't sure why people aren't clicking the main call-to-action, Clarity's heatmaps will answer that within a week.
• If you're running an e-commerce store and your cart abandonment rate is higher than it should be, session recordings will show you the exact friction point.
• If you've already got GA4 running and want to add a behavioural layer without paying for a tool like Hotjar, Clarity is the obvious move.
• If your website is new and you want to understand how real visitors interact with your layout before you invest in redesign work, start here.
• If your team is more comfortable with visual data than spreadsheets, the scroll maps and click overlays communicate clearly without requiring any analytics knowledge.

The Final Word

Google Analytics 4 is the foundation. If you own a website and you're not using it, you're flying blind. Microsoft Clarity is the layer on top that shows you why your numbers look the way they do. Used together — and they work better together — they give a small business owner a picture of their website that most companies were paying serious money for five years ago. If you're only going to learn one right now, start with GA4. If you already have it running, install Clarity this afternoon. The question was never really either/or.
