Conversion Rate Optimization (CRO) Glossary Terms/
Session recording is a user experience monitoring technique that captures a user’s entire interaction within a single session on your website or app. It includes mouse movements, scrolling behavior, clicks, and form inputs (excluding sensitive data).
How session recording in CRO works:
These recordings allow you to watch real users as if you’re looking over their shoulders.
You can observe exactly how users move their mouse, what areas they hover over, and how far they scroll down a page. This helps identify where attention drops off or what’s catching interest.
All user clicks are recorded, including normal interactions and repeated, rapid clicks—commonly referred to as rage clicks, which indicate frustration.
You can see which pages the user visits, how long they stay on each one, and in what order. This helps in analyzing whether your intended journey matches actual user paths.
You can track whether a user interacted with a form, where they paused, and whether they completed it. Sensitive data is usually masked automatically to maintain compliance.
Session recordings help you find things that analytics alone cannot show— like non-clickable buttons that users keep clicking or confusing layout choices that result in navigation loops.
By watching where users hesitate or abandon key flows (e.g., checkout or signup), you can make informed UX adjustments to reduce friction and increase conversions.
After making changes to a layout or flow, you can monitor how users respond without needing to run long A/B tests initially.
The recording tool captures front-end activity (mouse, scroll, taps) by injecting lightweight JavaScript into your site’s code. This script listens for user interactions.
Depending on the tool, data is sent in real time or in scheduled batches to the provider’s server. Most providers offer dashboards where you can filter and play back sessions.
The data collected isn’t a literal screen recording. It’s a recreation using DOM snapshots, event triggers, and state changes that emulate the user’s behavior visually.
Session recordings are designed with privacy in mind. They typically:
You can configure masking rules for fields like email, phone number, or user ID.
They use session recordings to watch how real users interact with layouts, features, and flows. This helps spot confusion points, dead clicks, and areas where users hesitate or get lost. It’s like a usability test, but with live data from actual users.
Conversion rate optimization (CRO) teams watch sessions to understand why users drop off or abandon forms. It helps test funnel performance, check if CTAs are seen and clicked, and tweak landing pages for better engagement and conversions.
Session recordings are useful for debugging frontend issues. Developers can replay bugs reported by users to see exactly what went wrong— no need to rely on vague descriptions or screenshots. QA teams also use it to test how new features behave in real usage.
When users face issues, support teams can review session recordings to understand what happened— whether it's a login problem, a failed payment, or something else. It helps resolve tickets faster and more accurately without going back and forth.
They use session recordings to validate feature adoption and understand user journeys. It helps answer questions like:
The main difference between session recording and session replay is terminology. Both refer to capturing and replaying user interactions on a website, but "session recording" emphasizes data capture, while "session replay" focuses on playback.
Functionally, they are the same in most analytics tools.
The main difference between session recording and heatmaps is that session recording captures full user sessions as video replays, while heatmaps visualize user behavior through aggregated click, scroll, or movement data.
Session recordings offer detailed interaction insights; heatmaps reveal general engagement patterns across a page.
What it is: A visual summary showing where users click, move, or scroll most—aggregated across many users.
Here’s a comparison table:
So, which one should you use?
Here are some session recording tools commonly used for Conversion Rate Optimization (CRO) audit services:
Lucky Orange provides session recording and replay tools that capture user interactions in real-time. It features visitor profiles, dynamic heatmaps, and form analytics to help identify drop-off points in user journeys, enhancing conversion strategies.
FullStory records all user sessions and links them to support tickets, allowing for quick identification of issues. It indexes recordings by user data and frustration signals, helping teams spot problem areas efficiently.
Crazy Egg offers session recordings that track user activity, including mouse movements and clicks. It provides insights into user behavior and helps optimize web pages based on engagement metrics, despite a less intuitive interface.
Mouseflow captures 100% of user sessions by default, providing insights into user behavior through session replays and heatmaps. It allows for detailed analysis of user interactions, helping identify friction points in the user journey.
Smartlook offers session recording on both web and mobile platforms, with features like heatmaps and event tracking. It helps teams understand user engagement and optimize conversion funnels effectively.
Microsoft Clarity is a free tool that captures user interactions and provides heatmaps and session recordings. It helps users understand behavior patterns and improve website usability without complex setups.
LogRocket records user sessions across web and mobile apps, providing insights into user behavior and technical issues. It features AI-driven error detection and integrates with support tools for efficient troubleshooting.
VWO combines session recordings with A/B testing and heatmaps, allowing businesses to analyze user behavior and optimize conversion funnels. It offers a user-friendly interface for easy navigation and insights.
Step 1: Filter sessions
Narrow down by device type, country, entry URL, exit URL, or conversion funnel.
Step 2: Prioritize high-value sessions
Look at sessions with form abandonments, rage clicks, or sudden exits.
Step 3: Tag insights
Use tags or notes to highlight design issues, user confusion, or bugs for your team.
Step 4: Take action
Document patterns. Share insights. Make design changes based on real behavior, not assumptions.
While powerful, session recordings are not perfect. Common limitations include:
Session recording helps in CRO by revealing how users interact with a page, uncovering drop-off points, confusion, and navigation issues that hinder conversion. This allows teams to refine user journeys based on real behavior.
Session recordings capture clicks, scrolls, mouse movements, form interactions, and page navigation, offering a complete playback of the user experience.
Session recording shows how users behave; A/B testing measures how they respond to different versions. Both inform optimization but serve different roles—recordings diagnose issues, testing validates solutions.
Most modern session recording tools run asynchronously and have minimal impact on performance, but excessive use or unoptimized scripts can affect load times.
Session recording can be GDPR-compliant when sensitive data is masked, users are informed, and consent is collected. Choose tools with built-in privacy features.
