Conversion rate optimisation tools for ecommerce split into two jobs: understanding why visitors don't buy (heatmaps, session recordings, surveys) and testing changes to fix it (A/B and multivariate testing). Most stores should start with the first before spending on the second, since watching real sessions usually surfaces obvious friction points for free.
A/B testing tools need enough traffic and conversions to reach statistical significance in a reasonable time — running a split test on a page with fifty visitors a day will take months to tell you anything reliable, so check your traffic against a tool's own sample-size guidance before buying one.
How we judged them
What matters when you're small.
Traffic required for valid test results
Confirm roughly how many weekly conversions your test pages get and check that against the tool's guidance for reaching statistical significance in a sensible timeframe.
Ecommerce platform integration
Look for a tool with a tested integration for your platform — Shopify, in particular, has specific apps and setups that avoid slowing down checkout pages.
Qualitative and quantitative in one place
Session recordings and heatmaps explain the 'why' behind a testing tool's 'what'. Some platforms bundle both; others need to be paired with a separate tool.
Site speed impact
Testing scripts can slow down page load, which itself hurts conversion. Check independent reviews of a tool's performance impact, not just its feature list.
The picks
What each one is actually good at.
Hotjar
Free limited plan, paid from about $32 a monthBest for: Understanding drop-off through heatmaps and recordings
The easiest way to start watching real customer sessions on product and checkout pages, with a genuinely useful free tier for small stores. Its A/B testing features are basic compared with a dedicated testing tool.
Microsoft Clarity
FreeBest for: Stores wanting session recordings and heatmaps at no cost
Fully free with no visitor caps, making it the obvious starting point for a small store with no CRO budget. Fewer advanced filtering and segmentation options than Hotjar's paid tiers.
VWO
From about $217 a monthBest for: Mid-size stores running structured A/B and multivariate tests
A mature testing platform with good statistical reporting and ecommerce-specific goal tracking. Priced for stores with enough traffic to run tests regularly, not occasional one-off experiments.
Convert
From about $99 a monthBest for: Privacy-conscious testing without slowing page load much
Known for a lighter script and stronger privacy compliance than some competitors, appealing to stores selling into markets with strict data rules. The visual editor is less polished than VWO's.
Lucky Orange
From about $18 a monthBest for: Small stores wanting recordings, heatmaps and simple A/B tests in one tool
A genuinely useful all-in-one for a small store's first CRO tool, bundling the basics at a low price. Testing features are simpler than a dedicated platform and better suited to easy layout changes than complex experiments.
Google Optimize alternative — Shopify's built-in A/B testing apps
Varies by app, typically from about $29 a monthBest for: Shopify stores wanting a native, low-setup testing option
Native Shopify apps avoid extra script conflicts and are quicker to set up than a general-purpose platform, but feature depth and statistical rigor vary a lot between apps — check reviews before committing.
Skip
What we'd leave alone.
- A/B testing platforms if your store gets under a few hundred conversions a month on the page you want to test — you won't reach significance in a useful timeframe.
- Any tool that requires a big implementation project before you've done basic session-recording research — cheap qualitative insight usually surfaces fixes faster than a full testing programme.
- CRO tools with heavy scripts on your checkout page without checking their measured speed impact first — a slower checkout can cost more in lost sales than the tool gains you.
Questions
Common questions.
Should a small store start with heatmaps or A/B testing?
Start with heatmaps and session recordings. They're cheaper or free, need no minimum traffic, and usually reveal obvious friction — like a confusing shipping cost display — that you can just fix without needing to run a formal test.
How much traffic do I need for A/B testing to work?
As a rough guide, you generally want at least a few hundred conversions per variation over the test period to reach reliable statistical significance. Check the specific tool's sample size calculator against your actual numbers before starting a test.
Will a CRO tool slow down my site?
Any tracking or testing script adds some load time, and heavier tools can measurably slow a page. Check independent speed benchmarks and test the impact on your own site rather than assuming it's negligible.
Is Microsoft Clarity really free with no catch?
Yes — it has no visitor limits or paid tiers gating core heatmap and recording features. Microsoft doesn't run ads against the data; it's offered as part of their broader advertising and analytics ecosystem.
