4.5 (90.91%) 11 votes

Conversion Rate Optimization (CRO) is a full-time job. However, with the right CRO Tools, any marketer can fix a leaky conversion funnel. You don’t need to be a plumber to use a spanner, and you don’t need to be an expert to use these CRO tools.

Together, we have over 60 years of website optimisation experience. This means we have clocked-up hundreds of hours working with the right tools (and the wrong ones!) This list will give you the benefit of our experience, helping you to get your funnel water-tight!

best cro tools

As we already offer a guide to best A/B testing tools for 2021, this list only includes a few of them. Most of these CRO tools are free, but any prices are given in terms of $/month (based on annual prices when they are available). All our reviews are based on personal experience or customer feedback. 

So, you think you might have a leaky funnel? The first step is to see where the leak is. These CRO tools gather performance data in the form of visual displays or reports. Unlike platforms such as Google Analytics, they tend to focus on user behaviour.

1. Mixpanel 

Cost/month – $0 for 1000 visitors  $174 for 5000 visitors  $304 for 10,000 visitors  $524 for 20,000 visitors  Contact for 20,000+

Analyze user behaviour across your sites and apps. Then send messages and run experiments from what you learned–all in Mixpanel

Mixpanel tracks your users and visualises their data for you. These visual displays are available in “Out of the Box reports”. The user interface is quick and intuitive, the platform handles large amounts of data without crashing, and the customer support is highly rated. However, interventions in the form of triggered messages are best served with an alternative tool.

2. Amplitude 

Cost/month – $0 for 10 million events  $995 for 100 million events Contact for 100 million+ events

See how Amplitude helps you understand your users, rapidly release better product experiences, and grow your business.

Amplitude has been designed primarily for SAAS companies. It tracks a range of events beyond the normal clicks and impressions, telling you when a customer has watched a video or performed a search. If you need to answer complicated questions such as “which of my product’s features do customer use most regularly?” this tool is ideal. However, paid monthly plans are very expensive.

3. Woopra

Cost/Month – $0 for 500,000 actions  $999 for 5,000,000 actions  Contact for 5,000,000+ actions

No hours sank into aggregating and cleaning data. No complex SQL queries required. Just the answers teams need to make smarter decisions, fast.

Woopra provides a similar solution to that of Mixpanel, tracking user behaviour and helping you to answer questions about how people use your site. It allows you to focus on any individual user, and to observe behaviour in real time.

4. Heap Analytics 

Cost/month – $0 for 5000 sessions  $499 for 20,000 sessions  Contact for 20,000+

Heap automatically captures every web, mobile, and cloud interaction: clicks, submits, transactions, emails, and more. Retroactively analyze your data without writing code.

Heap has a unique proposition for an analytics platform; it doesn’t just capture data, it records EVERY action performed by your users. The interface is simple, the system can be up-and-running in minutes, and the visualisation of your data is powerful. However, managing multiple sites with the same account has caused problems for some users.  

Heap cro tools

 

You have a good idea of where your funnel is leaking – the next step is to try your speed. Turn the tap on and watch the water run – any blockages will be obvious. To get a sense of which parts of your site might be slowing the whole thing down, check the speed on your home page, each category, and a standard product page. 

5. Google PageSpeed Insights 

Cost/month – $0

Get your PageSpeed score and use PageSpeed suggestions to make your web site faster through our online tool.

A simple, fast and effective page-speed analyser, with no strings attached. This is the ultimate pick-up-and-use CRO tool. It’s simple, versatile, and free, but even the biggest web developers use it.

8. Dareboost 

Cost/month – $22 for 1 page  $57 for 5 pages  $356 for 15 pages

Without any installation, we continuously analyze your web pages to detect quality and loading time issues. You can see the evolution of your pages’ major performance indicators on your dashboard at any time.

A front-end performance-monitoring tool. Without any installation, it reports on Search Engine performance, tracks user insights and measures loading speeds.

 

This is when you begin to understand the problem. User behaviour software (such as heatmaps, scrollmaps, and session recording tools) allows you to see how visitors experience your site. These CRO Tools show you the nuts, bolts and pipes as they are working.

9. Smartlook 

Cost/month – $0 for 1,500 sessions + 1 funnel  $34 for 7500 sessions + 1 funnel  $86 for 25,000 sessions + unlimited funnels

11. FullStory 

Cost/month – $0 for 1000 sessions  $199 for 1000+ sessions

Fullstory captures more data than any other digital intelligence platform and makes it easy to solve problems, find answers, and optimize your customer’s experience.

Provides curated recordings so that you can watch back particularly revealing user sessions. One particularly useful feature is the ability to filter sessions according to different types of “friction” behaviours (“Rage Clicks”, “Thrashed Curser” or abandoned forms).

12. UserTesting

Cost/month – Contact sales

Build better experiences and make more informed decisions by putting the customer at the centre of your business.

Whilst 75% of companies believe they are “customer-centric,” only 30% of consumers agree. UserTesting aims to bridge this “empathy gap” by connecting product developers and service providers with their consumers. Pre-formatted questionnaires and video interviews provide actionable data “in less than a day.” However, with no pricing visible on the product website, you better be ready for a premium price-tag.

13. Hotjar 

Cost/month – $0 for 2000 pageviews/day  $31 for 10,000 pageviews/day  $97 for 20,000 pageviews/day  $189 for 50,000 pageviews/day

Everything your team needs to uncover insights and make the right changes.

An old favourite from the user-behaviour category. It has been built with marketers in mind, and the emphasis is on usability. In addition to the usual heatmaps, surveys and session recording, Hotjar offers instant feedback messaging and test-user recruitment.

14. CrazyEgg 

Cost/month – $24 for 30,000 pageviews/month  $49 for 75,000 pageviews/month  $99 for 150,000 pageviews/month

Over 300,000 websites use Crazy Egg to improve what’s working, fix what isn’t and test new ideas.

One of the best-known user behaviour tools available, providing all of the usual mapping and recording features. There are a number of options for visualising user behaviour, including “click percent reports” and “confetti snapshots”, but the underlying technology is the same. An old tool this may be, but a sturdy one.

15. 5-Second Test 

Cost/month – Contact sales

Five second tests are a method of user research that help you measure what information users take away and what impression they get within the first five seconds of viewing a design.

A Five-Second test is a powerful user experience experiment that tests how much of an interface a user can recall after just five-seconds looking at it. If you need to make sure you are concise and communicate your value quickly, this sort of test is perfect. This platform collects participants, primes them for the test, and then collects the data from the tests.

You might think you understand your customers, but how can you be sure? These CRO tools let you get up to your wrists in data.

Cost/month – $19 for 1000 responses  $49 for 10,000 responses  $149 for 10,000+ responses Business features

Grow your business with the continuous feedback loop.

Like Survicate, Survey Sparrow aims to provide a comprehensive feedback loop, so that you get useful responses to design changes and instant warnings when things go wrong. The developers have tried to take the platform one step further, and enable you to easily act on reports. However, other than communicating insights with your team members, the actionability is limited.

19. Survey Monkey 

Cost/month – $32 for unlimited branded surveys  $96 for unlimited non-branded surveys

We make it easier than ever to create polls and survey questionnaires for learning about anything from customer satisfaction to employee engagement. Sign up to access our library of sample survey questions and expert-certified.

The surveys can be branded with company logos, responses can be made anonymous, and reporting is automated through pre-generated graphs.

24. LeadPages

Cost/month – $25 for 1 website  $48 for 3 websites and A/B testing  $199 for 50 websites and advanced integrations

Leadpages is the most effective, affordable way for small businesses to connect with an audience, collect leads, and close sales. Easily build landing pages, pop-ups, alert bars, and beyond.

To complement an attractive range of landing-page templates, LeadPages has developed a number of additional features. For example, the “Message-Match Ads” feature produces Facebook and Instagram ads based on the content of your landing pages. Other features, such as lead management support, drag-and-drop widgets, an image library and A/B testing facilities, make this an intriguing proposition.

25. Lander

Cost/month – $16 for 5000 visitors  $83 for 25,000 visitors

Start building landing pages in minutes with the best landing page designs!

Lander includes many of the features offered by LeadPages, but they have chosen to emphasise features like Dynamic Text Replacement and integrations with systems like Paypal. The customisation options are slightly less comprehensive, and the templates appear to be more limited, but this is still a very strong tool.

26. Landingi 

Cost/month – $29 for 5 domains, 100,000 visitors  $45 for 10 websites, 100,00 visitors  $59 20 domains 200,000 visitors

Landingi is a less expensive and simpler tool than Unbounce. It is very easy to use, even though the customisation possibilities are more limited.

 

Whether the water is running, or you can’t shift the clog, your next step is the same: testing. If you want to go beyond the guesswork, these CRO tools allow you to perform on-site experiments.

27. Glassbox (Convertize)

28. Google Optimize 360

Cost/month – Contact sales

Make a great impression on each and every visitor. Easily run tests on your website – for free – so it works better for your customers and your business.

This is the ultimate tool for web developers with the resources (time, money and expertise) to run continuous A/B tests. The price tag is only available through negotiation, so you know it will cost thousands of dollars a month. However, the integrations alone make this a no-brainer for larger enterprises.

29. Optimizely

Cost/month – Contact sales

Optimizely is the world’s leading experimentation platform, empowering marketing and product teams to test, learn and deploy winning digital experiences, every time.

This is one of the oldest and most powerful CRO tools on the market. It allows major marketing departments and software development teams to apply a “culture of optimization” to their offerings. However, this is undeniably an enterprise tool (with an enterprise price-tag). Elsewhere, we have created a list of cheaper Optimizely alternatives to choose from.

 

Giving customers a way to reach you helps you find and fix UX issues faster. Solving usability problems is far easier than hearing about them later – especially if they affect your customer reviews. 

30. Mobile Monkey

Cost/month – $0 for 1000 send credits  $21.75 for 2000 send credits  $51 for 6500 send credits

The best chatbot platform for marketing, sales, and customer support. Unified customer chat across messaging apps powered by OmniChat technology.

The all-in-one multichannel messaging platform that connects companies & customers.

Crisp is a fantastic chat tool for SMEs, with a free plan that gives you unlimited interactions. Sales teams, eCommerce stores and larger businesses may need a more flexible solution (automated chatbots and integrations with CRMs like Salesforce or Hubspot are only available with the Unlimited plan), but but Crisp is a great CRO tool for small to medium-sized business websites.

32. Live Chat

Cost/month – $16 per agent, basic chat  $33 per agent, full customisation  $50 per agent, all chat features

LiveChat is a complete customer service platform that delights your customers and fuels your sales.

Livechat is a slightly more complete customer engagement tool that gives you hundreds of integrations with each plan. Unfortunately, AI chatbots are only available with the sister product Chatbot, which costs a lot more. Even so, the number of possible integrations, and the potential for scaling with additional products, make this a good option for larger businesses.

Social Proof notifications add real-world context to your website – leveraging powerful effects such as social proof, urgency and scarcity. 

33. Nudgify

    Fomo increases trust, traffic, and sales with social proof automation.

    The principal of Social Proof and FOMO messaging is not specific to this tool, but it applies these messages through highly persuasive visual notifications.

There are some nice additional features, too, such as AI optimization and geo-location.

     

    If your funnel keeps your business going, these tools are your livelihood. That means you need to keep them in order, practice using them, and experiment whenever a new one comes along.
