Microsoft Clarity vs GA4 vs Hotjar: when to use heatmaps, session recordings, and analytics

Short answer

GA4 tells you what happened in numbers. Microsoft Clarity and Hotjar help you see how users behaved on the page: heatmaps, scroll, clicks, and session recordings. Clarity is a good free tool for quick UX diagnostics, Hotjar has broader product and research features depending on the plan, and GA4 remains the foundation for quantitative analytics. The biggest mistake is treating recordings as statistical proof instead of qualitative evidence.

What GA4 solves

GA4 is an analytics system. It shows visits, events, conversions, sources, campaigns, landing pages, basic funnels, and trends. It is good for questions such as: how many people came from a campaign, how many completed a form, which landing page has the highest conversion rate, and how channels differ.

But GA4 usually does not show why a user hesitated at a form, exactly where they clicked on a non-clickable element, or whether the layout broke for them. For that, you need behavior analytics.

What Microsoft Clarity solves

Microsoft Clarity is behavior analytics with heatmaps and session recordings. It helps find UX problems: rage clicks, dead clicks, scroll depth, form confusion, unreadable CTAs, mobile issues, or user behavior on a specific landing page.

Clarity is strongest as a quick audit tool. On a new landing page after launching PPC campaigns, you can check whether people even see the form, whether they click elements that are not links, or whether they leave the page after a specific section.

What Hotjar solves

Hotjar also offers heatmaps and session recordings, but it is often used for broader UX research too: feedback widgets, surveys, funnels, or segmented analysis depending on plan features. For teams that want to actively collect feedback and work with research questions, Hotjar may be a better fit.

The Clarity vs Hotjar decision is not only about features, but also about budget, privacy rules, integrations, and who will use the tool. Without a process, both tools end up as nice videos that no one watches.

How to combine the tools

Start in GA4: find a landing page with high traffic and low conversion. Then watch recordings and heatmaps in Clarity or Hotjar for that specific page. Look for repeated patterns: users do not reach the form, click an image, do not understand the price, or get lost in a checkout step.

Then propose a hypothesis and change: move the form higher, simplify the CTA, add the price, shorten the text, fix the mobile layout. Finally, evaluate the change quantitatively in GA4 or advertising data. A recording is inspiration for a hypothesis, not final proof.

Privacy and consent

Heatmaps and recordings can be sensitive. Mask personal data, form fields, emails, phone numbers, and payment information. Check consent mode and legal configuration. A tool that records user behavior must be connected deliberately, not as the last script in GTM without control.

For PPC landing pages, it is practical to set session recordings only for selected pages or segments so the team does not waste time and also minimizes unnecessary data collection.

What to watch on a PPC landing page

1. Does the user see the main CTA without scrolling? 2. Do they click elements that are not clickable? 3. Do they reach the form? 4. Do they leave the page at a specific section? 5. Does the mobile layout break? 6. Is the form too long? 7. Does traffic from Google Ads behave differently than traffic from Meta Ads?

This is exactly where Clarity or Hotjar complements GA4. GA4 says "the conversion rate is 1.2%." A recording shows that people on mobile do not see the button or accidentally click an inactive card.
