What is behavior analytics and how is it different from web analytics?
Web analytics (like GA4) tells you what users do in aggregate — how many sessions, what conversion rate, where traffic comes from. Behaviour analytics tools (Hotjar, Microsoft Clarity, FullStory) show you how individual users interact with your website — their mouse movements, scroll depth, clicks, and navigation paths — via session recordings and heatmaps. The combination of both gives you the "what" (GA4) and the "why" (behaviour analytics) needed to diagnose and fix conversion problems.
What is the difference between Hotjar, Microsoft Clarity, and FullStory?
Microsoft Clarity is completely free with unlimited sessions, heatmaps, and session recordings — excellent for businesses wanting behaviour analytics at zero cost. Hotjar offers a freemium model with more advanced features including surveys, feedback polls, and funnel analysis tools in paid tiers. FullStory is an enterprise-grade platform with complete digital experience data, advanced search and segmentation of session recordings, and developer-focused error tracking — best for larger SaaS and ecommerce businesses. We recommend the right tool based on your budget and analytical needs.
What is a heatmap and what does it tell me?
A heatmap is an aggregated visualisation of user interactions across thousands of sessions, shown as a colour overlay on your webpage — hot colours (red, orange) indicate high interaction and cool colours (blue, green) indicate low. Click heatmaps show where users click (including clicks on non-clickable elements, which indicates confusion). Scroll heatmaps show how far down the page users scroll (showing you what percentage of visitors see each section). Move heatmaps show mouse movement patterns. Together they reveal what users pay attention to and what they ignore.
What is a session recording and how do I use it for CRO?
A session recording captures a video-like replay of an individual user's interaction with your website — showing their mouse movements, scrolls, clicks, form interactions, and navigation. For CRO, you watch recordings filtered to specific scenarios: users who abandoned your checkout, users who rage-clicked a specific button, users who visited your pricing page but did not sign up. These recordings reveal specific UX problems — confusing navigation, unclear CTAs, broken form validations, mobile layout issues — that aggregate metrics cannot detect.
What is a rage click and why should I care about it?
A rage click is when a user clicks rapidly on an element multiple times in quick succession — typically because they expect it to be clickable (a button, link, or interactive element) but it does not respond. Rage clicks indicate user frustration and are strong signals of UX problems. Microsoft Clarity, Hotjar, and FullStory all automatically detect and tag rage click sessions, making it easy to find and watch recordings where users encountered this frustration on specific pages.
What is A/B testing and how does it fit with behavior analytics?
A/B testing shows different versions of a page (or element) to randomly split audiences and measures which version produces a higher conversion rate. Behaviour analytics complements A/B testing in two ways: it helps you form better hypotheses for what to test (based on session recordings and heatmaps showing actual friction points), and it helps you understand why one variant outperforms another (comparing heatmaps and recordings for the winning and losing variants). We configure analytics tracking so A/B test variant data flows correctly into GA4 for analysis.
How do I set up targeted session recordings?
Targeted recordings filter which sessions are captured based on user behaviour — for example: users who visited the pricing page and did not convert, users who spent more than 2 minutes on the checkout page, users on mobile devices, or users who came from a specific ad campaign. This is far more efficient than recording all sessions, as it focuses your analysis time on the sessions most likely to reveal conversion problems. We configure targeted recording segments for your highest-priority conversion scenarios.
Does adding a behavior analytics tool slow down my website?
Microsoft Clarity has a very small performance impact (the script is asynchronous and hosted on Microsoft's CDN). Hotjar's impact is slightly higher and is loaded asynchronously. FullStory has the largest script weight due to its complete interaction capture. For performance-sensitive websites, we implement these tools via GTM with Consent Mode integration so they only load after user consent, and configure sampling rates to reduce the performance impact of full session recording.
What is funnel analysis in a CRO context?
Funnel analysis tracks the drop-off rate between each step of a conversion process — from landing page, to product page, to add-to-cart, to checkout initiation, to payment, to confirmation. It quantifies how many users enter each step and how many proceed to the next, showing you which step has the highest drop-off and therefore the largest revenue opportunity. Hotjar and FullStory provide built-in funnel tools; GA4's Funnel Exploration provides the same capability with more detailed segmentation and attribution context.
How do I prioritise which CRO tests to run first?
We prioritise CRO tests using an ICE score (Impact, Confidence, Ease): Impact — how much improvement in conversion rate is realistic if this element is optimised? Confidence — how strong is the evidence from session recordings, heatmaps, and analytics that this is genuinely a problem? Ease — how complex is the development work to build the variant? High-impact, high-confidence, low-effort tests go first. We produce a prioritised CRO roadmap scoring every hypothesis identified during the behaviour analytics review.
