5 Free Website Conversion Rate Checkers You Should Try

Your website has traffic. You can see the numbers in your analytics dashboard. But you cannot see, from the outside, why so many of those visitors leave without converting. You know the conversion rate is lower than it should be. What you do not know is what is causing it.

That is where a free website conversion rate checker comes in. These tools analyze your website and tell you, with varying degrees of specificity, what is working for conversions and what is not. Some measure the conversion rate itself. Some identify the factors that influence it. The best ones do both and give you a prioritized list of fixes.

But here is the issue: most people searching for a free website conversion rate checker end up using tools that measure traffic or speed, not conversion performance. Google Analytics tells you what your conversion rate is, but not why it is that number. Speed tools tell you how fast your page loads, but not whether it persuades anyone to take action. You need tools that go deeper.

This guide covers five free tools that actually help you understand and improve your conversion rate. Each one approaches the problem differently. Used together, they give you a complete picture of your conversion performance without spending a dollar.

What a Free Website Conversion Rate Checker Should Actually Tell You

Before we get into the tools, let us define what you should expect from a conversion rate checker. There are two types of data that matter.

The first is quantitative data: your actual conversion rate, expressed as a percentage. This is the number of conversions divided by the number of visitors, multiplied by 100. If you need a refresher on the math, we have a full guide on how to calculate conversion rate.

The second is diagnostic data: the specific factors on your page that are helping or hurting that number. This includes things like your headline clarity, CTA visibility, trust signal presence, form friction, mobile usability, and page load speed.

Most tools give you one or the other. Very few give you both. The ideal free website conversion rate checker tells you what your conversion rate is, why it is that number, and what to change to improve it. That is the standard we are evaluating against.

The 5 Best Free Website Conversion Rate Checkers

1. CROgrader — Best for Diagnosing Why Your Conversion Rate Is Low

Website: crograder.com

If you want to understand why visitors are not converting, CROgrader is the most useful free tool available. It is an AI-powered conversion rate checker that analyzes your page against 50+ conversion factors and returns a detailed conversion score with prioritized recommendations.

Unlike analytics tools that show you numbers, CROgrader shows you causes. It evaluates your headline and value proposition, CTA design and placement, trust signals, form length, visual hierarchy, mobile readiness, objection handling, and page copy persuasiveness. Each factor is scored and prioritized by likely impact on your conversion rate.

What it checks:

• Headline clarity and value proposition strength
• CTA placement, contrast, copy, and urgency
• Trust signals including testimonials, logos, badges, and guarantees
• Form field count and friction level
• Visual hierarchy and information architecture
• Mobile conversion readiness
• Objection handling and risk reversal elements
• Content structure and readability

How to use it:

Paste your URL into CROgrader and wait roughly sixty seconds. You get a conversion score plus a detailed breakdown of every factor the tool analyzed, sorted by priority. Start with the items flagged as high impact. Those are the changes most likely to move your conversion rate.

What makes it different:

CROgrader is the only free website conversion rate checker that focuses exclusively on conversion optimization. It does not check your page speed or SEO. It checks whether your page is built to convert visitors into customers. That is a critical distinction, because you can have a fast, well-optimized page that still converts poorly if the messaging, trust signals, and CTA strategy are wrong.

No signup required. No email gate. You get results immediately.

If you are new to conversion optimization, pair CROgrader with our beginner's guide to CRO to understand the context behind each recommendation.

2. Google Analytics (GA4) — Best for Measuring Your Actual Conversion Rate

Website: analytics.google.com

Google Analytics 4 is the standard tool for tracking your actual conversion rate. It does not check why your conversion rate is a certain number, but it tells you what that number is across every page, traffic source, device, and audience segment.

If CROgrader tells you what to fix, Google Analytics tells you whether the fix worked. The two are complementary. You need GA4 installed and properly configured to measure the impact of any conversion optimization work you do.

What it checks:

• Page-level conversion rates (when events and conversions are configured)
• Traffic source performance (organic, paid, social, direct, referral)
• Device and browser breakdowns
• User flow and drop-off points in multi-step funnels
• Audience segment comparison
• Landing page performance metrics
• Session engagement metrics (engagement rate, time on page, bounce rate)

How to use it:

The first step is making sure you have conversion events set up correctly. In GA4, you define key events (formerly called conversions) — form submissions, purchases, signups, downloads, or whatever your conversion action is. Then navigate to the Reports section, drill into Landing Pages, and sort by conversion rate.

Look for patterns. Which pages convert best? Which traffic sources drive the highest-converting visitors? Where do users drop off? These patterns tell you where to focus your optimization efforts.

What makes it different:

GA4 is the only tool on this list that tracks real user behavior at scale over time. It shows you trends, not snapshots. The challenge is that GA4 tells you what is happening, not why. A page with a 1.2% conversion rate is underperforming, but GA4 will not tell you that it is because your CTA is invisible, your headline is vague, or your form has twelve fields. For the why, you need CROgrader or a behavioral analytics tool.

Pricing: Free.

3. Hotjar (Free Plan) — Best for Seeing How Users Behave on Your Pages

Website: hotjar.com

Hotjar gives you a window into how individual users experience your pages. The free plan includes heatmaps, session recordings, and basic feedback tools — all of which help you understand conversion behavior in ways that quantitative tools cannot.

Heatmaps show you where people click, how far they scroll, and what they spend time looking at. Session recordings let you watch actual users navigate your pages, seeing exactly where they get confused, frustrated, or distracted. This is behavioral data that reveals conversion problems you would never catch from analytics alone.

What it checks:

• Click heatmaps (where users click, tap, and interact)
• Scroll heatmaps (how far users scroll before leaving)
• Session recordings (full video replays of individual user sessions)
• Rage clicks and dead clicks (indicators of frustration)
• User feedback polls (ask visitors specific questions)
• Basic funnel visualization

How to use it:

Install the Hotjar tracking script, then start collecting data on your highest-traffic pages. Focus on your key landing pages and conversion pages first. After a few days of data collection, review the heatmaps: Are users scrolling past your CTA without seeing it? Are they clicking on elements that are not clickable? Watch five to ten session recordings and look for patterns. If three out of five users hesitate at your form, you have found a friction point.

What makes it different:

Hotjar shows you the qualitative side of conversion performance. Where GA4 tells you that 97% of visitors leave without converting, Hotjar shows you exactly what those visitors did before they left. Maybe they scrolled halfway down the page and stopped, never reaching your CTA. Maybe they clicked the pricing link and immediately bounced. These are insights you cannot get from any other type of tool.

Pricing: Free plan includes 35 daily sessions and unlimited heatmaps. Paid plans start at $32/month.

4. Microsoft Clarity — Best for Free, Unlimited Session Recordings and Heatmaps

Website: clarity.microsoft.com

Microsoft Clarity is a direct competitor to Hotjar's free tier, but with one significant advantage: there are no data caps. Where Hotjar's free plan limits you to 35 sessions per day, Clarity gives you unlimited session recordings, unlimited heatmaps, and unlimited users. For a free website conversion rate checker focused on behavioral data, the value is hard to beat.

Clarity also includes a feature called Smart Events that automatically detects certain user interactions, plus an AI-powered Copilot that summarizes session patterns and highlights anomalies.

What it checks:

• Unlimited session recordings with full playback
• Click, scroll, and area heatmaps
• Rage clicks, dead clicks, and excessive scrolling detection
• Smart Events for automatic interaction tracking
• JavaScript error detection during sessions
• Session insights and filtering by behavior type
• Google Analytics integration for connecting behavioral data to conversion metrics

How to use it:

Install the Clarity tracking code, then let it run for at least a week to collect meaningful data. Use the dashboard filters to isolate sessions where users visited your conversion pages. Sort by rage clicks or dead clicks to find frustration points. Watch recordings of users who started but did not complete your conversion action — the drop-off moment often reveals the exact problem.

The Google Analytics integration is particularly useful. You can connect Clarity to GA4 and filter session recordings by traffic source, device, or conversion event. This means you can watch recordings of only the users who came from a specific campaign and did not convert, giving you highly targeted behavioral insights.

What makes it different:

Clarity is the most generous free behavioral analytics tool available. No session limits, no feature gates, no email-gating of reports. For small and mid-size sites that need session recording data but cannot justify a paid Hotjar plan, Clarity delivers the same core functionality at zero cost. The tradeoff is that Clarity's interface is less polished than Hotjar's, and it lacks Hotjar's survey and feedback features.

Pricing: Completely free. No paid tier.

5. Lucky Orange (Free Plan) — Best for Real-Time Conversion Monitoring

Website: luckyorange.com

Lucky Orange combines several conversion checking tools into a single platform: heatmaps, session recordings, live chat, surveys, conversion funnels, and form analytics. The free plan gives you access to the core features on a limited scale.

What sets Lucky Orange apart is its real-time focus. You can watch live visitors navigate your site as it happens, see which pages they are on, and even initiate a live chat to intervene if they appear to be struggling. The form analytics feature is particularly useful for conversion checking — it shows you exactly which form fields cause abandonment.

What it checks:

• Dynamic heatmaps (click, scroll, and mouse movement)
• Session recordings with event timeline
• Conversion funnels with step-by-step drop-off data
• Form analytics (field-level abandonment, time per field, refill rate)
• Live visitor dashboard (see who is on your site right now)
• Survey and feedback collection
• Announcements and targeted messaging

How to use it:

Set up conversion funnels for your key user journeys (homepage to product page to cart to checkout, or landing page to form submission). Lucky Orange will show you exactly where in the funnel users drop off and how significant the drop is at each step. Use the form analytics on your conversion forms to identify which fields users struggle with, skip, or abandon on.

The form analytics feature deserves special attention. If you run a lead generation site, your form is your conversion point. Lucky Orange shows you the average time spent on each field, the refill rate (how often users retype their answers), and the field where most users abandon the form. That level of specificity tells you exactly what to simplify.

What makes it different:

Lucky Orange is the only free tool on this list with built-in form analytics and conversion funnel tracking. Where Hotjar and Clarity show you general behavioral data, Lucky Orange maps that behavior specifically to your conversion steps. The form analytics alone can reveal conversion rate improvements that no other free tool would surface.

Pricing: Free plan available with limited data retention and sessions. Paid plans start at $32/month.

How to Use These Tools Together for a Complete Conversion Checkup

No single free website conversion rate checker covers everything. Here is how to combine all five for a thorough conversion checkup that costs nothing.

Step 1: Diagnose your conversion factors with CROgrader. Run your key pages through CROgrader to identify the structural and persuasion issues that are dragging your conversion rate down. This gives you a prioritized fix list.

Step 2: Quantify the problem with Google Analytics. Look at your page-level conversion rates in GA4. Identify which pages have the lowest conversion rates and which traffic sources send visitors who convert best. This tells you where the problem is worst.

Step 3: Understand user behavior with Clarity or Hotjar. Install one (or both) behavioral analytics tools. Collect heatmap and session recording data on your worst-performing pages. Watch what users actually do before they leave without converting.

Step 4: Pinpoint form friction with Lucky Orange. If your conversion action involves a form, use Lucky Orange's form analytics to identify which fields are causing abandonment.

Step 5: Fix, measure, repeat. Use CROgrader's recommendations to prioritize changes. Implement the highest-impact fixes first. Then use GA4 to measure whether the conversion rate improved.

This workflow takes about thirty minutes to set up and gives you conversion intelligence that most companies pay thousands for through consultants or enterprise tools. If you want a structured framework for this process, our guide on running a free CRO audit walks through each step in detail.

What Free Conversion Rate Checkers Cannot Do

Free tools have limits, and it is important to understand them so you do not waste time expecting something they cannot deliver.

They cannot run A/B tests. Free conversion rate checkers can identify problems and suggest fixes, but they cannot test whether a specific change actually improves your conversion rate. For that, you need an A/B testing tool like Google Optimize's successors or a dedicated platform.

They cannot attribute revenue to specific changes. You can track that your conversion rate went from 2.1% to 2.8% after making changes, but free tools generally do not connect that to revenue impact at the individual change level.

They cannot replace strategic CRO expertise. These tools identify issues. They do not tell you whether a pricing page restructure will outperform a headline change. Strategy and prioritization still require expertise — either your own or a consultant's.

They have data limitations. Free plans limit session counts, data retention, or feature access. For high-traffic sites, you will hit these limits quickly and need to upgrade or rotate tools.

That said, for most small to mid-size websites, these five free tools provide more than enough data to identify and fix the conversion issues that matter most.

Start With Your Conversion Score

If you are looking for a free website conversion rate checker and you only have time for one tool, start with CROgrader. It takes sixty seconds, requires no setup, and gives you a specific, prioritized list of what is hurting your conversion rate and what to fix first.

Then layer in GA4 for measurement, Clarity or Hotjar for behavioral insights, and Lucky Orange for form-level analysis as needed.

The difference between a 1.5% and 3% conversion rate is not traffic. It is not ad spend. It is what happens on the page after the visitor arrives. These tools help you see what is happening — and more importantly, what to change.
