Run A/B Tests on Your Website with Inspectlet

We're excited to announce that you can now run A/B tests directly inside Inspectlet. Create experiments, modify your pages with a visual editor, and measure the impact on the metrics that matter most to your business — all without writing a single line of code.

What Is A/B Testing?

A/B testing (also known as split testing) is a controlled experiment that compares two versions of a webpage. Half of your visitors see the original version of your page (the "control"), and the other half see a modified version (the "variation"). By measuring how each group performs against your goals — like signup rate, revenue per visitor, or click-through rate — you can empirically determine which version works best and quantify exactly how much better it is.

No more guessing whether that new headline will improve conversions. No more debating button colors in meetings. A/B testing gives you data instead of opinions.

The Visual Editor

Creating an experiment in Inspectlet doesn't require any code changes to your site. Our visual editor lets you point and click to make changes directly on your live webpage:

You can modify text, swap images, change button styles, rearrange elements, hide sections, or adjust any visible aspect of your page. The visual editor generates the changes automatically — your original page stays untouched, and Inspectlet applies the modifications on the fly for visitors assigned to the variation group.

Measuring What Matters

Every experiment is tied to one or more Goals that define what success looks like. Goals can track actions like:

• Signups — did the visitor create an account?
• Purchases — did they complete a transaction?
• Revenue — how much did they spend?
• Page visits — did they reach a key page like a pricing or confirmation page?
• Custom events — any action you're already tracking with Inspectlet

Inspectlet tracks each goal across both groups and presents clear results showing the conversion rate for each version, the improvement percentage, and statistical confidence so you know when you have a winner.

How It Works

1. Create an experiment — Head to your Dashboard and click A/B Experiments
2. Set up your variation — Use the visual editor to make changes to your page
3. Define your goals — Choose which metrics you want to improve
4. Launch — Inspectlet automatically splits traffic and starts collecting data
5. Review results — Watch the data come in and see which version wins

You can run unlimited experiments simultaneously, testing different changes on different pages across your site.

A/B Testing + Session Replay: A Powerful Combination

Here's what makes A/B testing inside Inspectlet uniquely powerful: you can watch session recordings of visitors in each test group. Instead of just seeing that Version B had a 15% higher conversion rate, you can watch why. Maybe users in the control group were scrolling past your CTA without noticing it, while users in the variation group engaged with it immediately.

This combination of quantitative data (conversion metrics) and qualitative insight (session replay) gives you a much deeper understanding of what's working and what isn't.
