Quick Answer

Conversion rate optimization pros rely on a toolkit, not a single tool. This list covers 32 tools grouped by the job they do: web analytics, benchmarking and dashboards (such as Google Analytics 4, Matomo and Similarweb); voice of customer and user testing (SurveyMonkey, UserTesting, Lyssna); experimentation and QA (Omniconvert Explore, Unbounce, BrowserStack, Sauce Labs); communication and organization (Slack, Asana, Trello); and design (Photoshop, Snappa, ColorZilla). Analytics shows where visitors drop off, feedback explains why, and an experimentation platform proves which fix works. Omniconvert Explore combines A/B testing, on-site surveys and personalization in one platform.

Key Takeaways

A CRO toolkit covers five jobs: measuring behavior, hearing the customer, testing changes, coordinating the team and producing the creative for tests.
Analytics and dashboards show where visitors drop off, while surveys and user testing explain why they leave; you need both to write a strong test hypothesis.
An experimentation platform is the only tool that proves a change caused a result; Omniconvert Explore adds on-site surveys and personalization to A/B testing.
Several tools from earlier versions of this list have closed or changed: Skype, Pocket, Beeketing and CrossBrowserTesting are gone, and Formisimo and UsabilityHub were renamed Zuko and Lyssna.
Good CRO depends on process and collaboration as much as software: clear goals, data-driven decisions and continuous testing across marketing, design and IT.

Conversion rate optimization pros do not rely on one tool. They use a toolkit of 32 tools that cover five jobs: web analytics and dashboards to measure behavior, voice of customer and user testing tools to hear the customer, experimentation tools to test changes, communication and organization tools to coordinate the team, and design tools to build the variations. This guide lists each tool by the job it does and what it is best for.

Conversion rate optimization is a process that helps you grow your business. The focus is the one thing that makes the difference between success and failure in CRO: you either put all of your attention on this process, or you hunt for fast winning tactics. The first choice always wins.

Why do CRO pros need a toolkit?

CRO needs three resources: people who understand a bit of human psychology, are creative and know web analytics; budget; and good tools. No single tool covers the whole process. Analytics shows where visitors drop off, feedback tools explain why, experimentation tools prove which fix works, and project tools keep the team moving.

Besides these three resources, the entire team, business unit or company should focus on improving the CRO process. A CRO culture and clear procedures give growth a boost. Six principles keep the toolkit useful:

Integrate the tools. Web analytics, heatmaps, user feedback and A/B testing each give a partial view. Together they produce actionable insight about user behavior and site performance.
Decide with data. Base decisions on analytics and test results, not on assumptions or generic best practices.
Test continuously. Ongoing experimentation finds what converts visitors into customers and adapts as results change.
Put the user first. Improve the experience based on direct feedback and observed behavior.
Align with goals. Clear objectives keep every optimization activity tied to the business's overall goals.
Collaborate across teams. Marketing, design and IT must work together to optimize the user journey.

This article is the broad toolkit. For a deeper comparison of the core platforms, see our guides to the best CRO tools, CRO audit tools, CRO analytics tools and free CRO tools.

What changed since the first version: Skype (retired by Microsoft in May 2025), Pocket (shut down by Mozilla in July 2025), Beeketing (closed; its domain now redirects to ShopBase) and SmartMail (now an email marketing agency, not a tool) were removed. CrossBrowserTesting was discontinued by SmartBear in 2023, so this list shows BrowserStack Live, which the original entry already linked to. Formisimo is now Zuko, and UsabilityHub is now Lyssna.

Web analytics, benchmarking and dashboard tools

Web analytics is the backbone of CRO: it shows how users behave and where the marketing chain breaks. Benchmarking tools set realistic objectives against competitors, dashboards keep key metrics visible, and form analytics shows exactly where users abandon a form. Google Analytics 4 is the common starting point; Matomo is the open-source alternative.

Benchmarking is crucial for setting realistic objectives. Use benchmarks wisely: comparing your metrics with competitors gives insight, but copying them without adapting to your own customers can erode trust. Effective use of quantitative data means you can "zoom in" for detail and "zoom out" for the broader picture, to find where the biggest opportunities are.

1. Similarweb

Similarweb gives insight into competitors' website traffic, so you can understand market trends and identify growth opportunities.

Best for: benchmarking your traffic sources and volume against competitors.

2. Owler

Owler, now part of Meltwater, sends competitive updates that help you track and respond to industry movements and competitor strategies.

Best for: following competitor news, funding and launches without manual research.

3. Google Analytics 4

Google Analytics gives a layered view of your website, with deep insight into audience characteristics, behavior and site performance. Google Analytics 4 replaced Universal Analytics, which stopped processing data in 2023.

Best for: the core numbers of any CRO program: traffic, funnels, conversions and revenue by channel.

4. Matomo (formerly Piwik)

Matomo is an open-source analytics platform that lets you fully customize your reports and keep control of your data, all in one place.

Best for: teams that need data ownership and privacy control.

5. Cyfe

Cyfe is an all-in-one business dashboard app that lets you monitor and visualize all your business data in one place.

Best for: small teams that want marketing, sales and web metrics on one screen.

6. Geckoboard

Geckoboard is a KPI dashboard tool that makes it simple to share key metrics across the organization, so everyone stays aligned and informed.

Best for: live dashboards on office screens and in team channels.

7. Adobe Commerce Intelligence (formerly RJMetrics)

RJMetrics became Magento Business Intelligence and is now Adobe Commerce Intelligence. It is a business intelligence tool for decision-makers in eCommerce.

Best for: Adobe Commerce stores that need revenue, cohort and customer reporting.

8. Zuko (formerly Formisimo)

Zuko is a form analytics tool that measures how users interact with online forms, field by field, so you can raise form completion rates.

Best for: checkout, sign-up and lead forms with high abandonment.

Voice of customer and user testing tools

Voice of customer tools collect direct feedback, and user testing tools show how real people use your site. Many businesses fail to hear what customers ask for, which leads to weak A/B tests and costly changes. Surveys tell you what visitors think; usability tests show where they struggle.

Listening to your customers is essential. On-site surveys capture feedback at the moment of behavior. Omniconvert Explore runs behavioral surveys triggered by what visitors do on your site or the channel they came from, next to its A/B tests and overlays (see tool 13). For broader research, use the tools below. Read more about user testing.

9. SurveyMonkey

SurveyMonkey is a versatile survey tool for researching your target market in depth and making smarter, data-driven decisions, up to enterprise level.

Best for: email and link surveys to customers and target audiences.

10. Loop11

Loop11 is a remote usability testing tool. You evaluate your site's user experience from a distance and get actionable insight without in-person studies.

Best for: task-based usability tests with measurable success rates.

11. UserTesting

UserTesting provides videos of real users interacting with your website or app, a direct window into the experience that helps you find pain points and opportunities.

Best for: hearing users think aloud as they complete key tasks.

12. Lyssna (formerly UsabilityHub)

Lyssna lets you upload designs and get feedback from testers, so you can decide which design will work best for your users.

Best for: five-second tests, first-click tests and design preference tests before you build.

Experimentation, QA and engagement tools

Experimentation turns insight into tests that measurably change site performance. A/B testing tools create and run the variations, QA tools confirm each variation works on every browser and device, and engagement tools act on visitor behavior in real time. Omniconvert Explore combines A/B testing, surveys and personalization in one platform.

Creating and running A/B tests is how you find the most effective elements of your website or app. Before a test goes live, check that every variation works across browsers and devices, or the data will be wrong.

13. Omniconvert Explore

Omniconvert Explore is an A/B testing platform with an intuitive visual (WYSIWYG) editor, so you can create and deploy tests without deep technical knowledge. It also runs behavioral on-site surveys, pop-ups and overlays, and web personalization from the same script.

Best for: teams that want testing, customer feedback and personalization in one tool. A/B testing is free for up to 50,000 tested visitors.

14. Unbounce

Unbounce specializes in landing page optimization. You create, deploy and test different landing pages quickly to see which one converts best.

Best for: paid campaign landing pages built without developers.

15. BrowserStack Live

BrowserStack Live lets you test your website on real browsers and devices, so your site and your test variations give a consistent experience to every user.

Best for: manual QA of test variations before launch.

16. Sauce Labs

Sauce Labs is a cloud platform for automated testing of web and mobile applications, supporting continuous integration and delivery workflows.

Best for: development teams that automate cross-browser and mobile testing.

17. WebEngage

WebEngage is a customer engagement and retention platform. It lets you show targeted messages based on visitor behavior and preferences, for more personalized interactions.

Best for: triggered, cross-channel messages to known users.

Communication, collaboration and organization tools

CRO involves many people and many moving parts: research, hypotheses, designs, development and results. Communication tools keep the team aligned, and organization tools track tasks, deadlines and the testing roadmap. They make sure every step of the optimization process gets done.

18. Slack

Slack is a real-time messaging platform with archiving and search, which makes it easy for teams to communicate and collaborate on projects.

Best for: day-to-day team communication and test result alerts.

19. Google Sheets

Google Sheets lets teams create, share and edit spreadsheets together in real time, to track client status, deadlines and other critical data.

Best for: a simple test backlog and prioritization sheet.

20. Asana

Asana helps teams stay organized and focused on results by managing projects, tasks and communication in one platform.

Best for: structured workflows across marketing, design and development.

21. Trello

Trello gives a visual overview of your projects on boards, where tasks move between lists according to their status.

Best for: a kanban board of tests from idea to live to analyzed.

22. Basecamp

Basecamp is a project management tool that organizes work into separate projects, where teams collaborate, track progress and meet deadlines.

Best for: agencies that run CRO projects for several clients.

Best for: individual optimizers planning their week.

25. ProjectManager

ProjectManager helps you plan, schedule and collaborate on projects of any size, with support for both agile and waterfall methods.

Best for: larger programs that need Gantt charts and resource planning.

Design and other useful tools

An optimizer needs many skills, from understanding behavior and data to creating the assets for test variations. Design tools produce banners, graphics and page mockups; font and color tools keep variations on brand; and an SEO audit tool makes sure changes do not hurt search visibility.

26. Adobe Photoshop

Photoshop is the industry-standard tool for complex graphics, detailed illustrations and polished artwork for any part of your digital experiments.

Best for: designers producing high-fidelity variation assets.

27. Snappa

Snappa offers an intuitive interface, high-quality free-to-use images and easy-to-edit templates for creating banners and other graphics quickly.

Best for: marketers who need graphics without a designer.

28. Pixelied

Pixelied is a user-friendly design tool for social media posts, blog headers, email campaigns and more.

Best for: quick, template-based visuals for campaigns.

29. WhatTheFont

WhatTheFont helps you identify fonts quickly, which keeps typography consistent across your marketing.

Best for: matching fonts when you build a variation.

30. ColorZilla

ColorZilla is a browser extension for color tasks such as color picking, palette creation and color analysis.

Best for: picking exact on-brand colors from a live page.

31. SEOmator

SEOmator automates website audits and produces detailed SEO reports that help you optimize your site for better search rankings.

32. Design Wizard

Design Wizard is online graphic design software for creating professional visual content in minutes.

Best for: fast, professional-looking visuals from templates.

How the tools fit the CRO process

Each tool group supports one stage of a continuous CRO cycle. Analytics finds where users experience friction, feedback and user testing explain why, design tools build the fix, experimentation proves it, and organization tools keep the cycle running. Because markets and user preferences change, the cycle never ends.

CRO stages and the tools that support them. Source: Omniconvert
CRO stage	What it does	Tool groups
Understand user behavior	Pinpoints where users experience friction or drop off	Analytics, dashboards, form analytics
Find the reason	Reveals what confuses users and what stops them converting	Surveys, user testing
Apply psychology and design	Turns insight into variations of calls to action, colors and layouts	Design tools
Test and prove	Shows which variation works, based on real user reactions	Experimentation and QA tools
Repeat and scale	Keeps regular reviews and tests running as conditions change	Communication and organization tools

CRO tools should not work in isolation. Integrate CRO with SEO, content marketing and social media, so every part of the funnel is optimized for conversions. Content that keeps users engaged informs your content strategy, SEO brings more qualified traffic, and social media extends reach at each stage of the funnel.

Advanced tools also use predictive analytics and machine learning to forecast user actions from historical data. That lets you personalize messages for different segments before problems appear.

Ultimately, CRO supports sustainable growth. When conversion efficiency improves, you can reinvest the savings into more traffic and better products, and optimization and growth feed each other. Read more about conversion rate optimization.

How to choose the right CRO tools

Choose CRO tools by starting from your goals, not from a feature list. Consider your website size, traffic volume, team skills and budget, check integrations with your existing stack, and try a free plan or trial before you commit. Most teams need one tool per job, not every tool on this list.

Define your goals
Decide what you need to improve: sales, leads, sign-ups or donations. The goal decides which tool groups matter most.
Map your gaps
List the five jobs (measure, listen, test, coordinate, create) and note which ones your current tools already cover.
Match tools to your size
Consider your traffic volume, your team's technical skills and your budget. Most vendors price by traffic or seats.
Check integrations and support
Pick tools that connect to your analytics, eCommerce platform and CRM, and that offer good customer support.
Trial before you commit
Use a free plan or trial to test the tool on your own site, then confirm current pricing on the vendor site.

To manage A/B testing, surveys and personalization in one place, use an integrated platform such as Omniconvert Explore.

Frequently Asked Questions

1Why is CRO important for my business?

CRO helps you get more value from the traffic you already have. Instead of spending more money to bring in extra visitors, you convert more of the visitors who already arrive. That makes your marketing budget work harder, raises return on investment, and turns more visitors into customers or leads.

2How do I choose the right CRO tool for my website?

Start with your goal and the question you need answered. Then consider the size of your website, your traffic volume, your team's technical skills and your budget. Choose tools that integrate with your existing stack, offer the analytics and testing features you need, and come with good support. Use a free plan or trial to test a tool before you commit.

3How does user feedback play a role in CRO?

User feedback shows what visitors like, what confuses them and what stops them from converting. Surveys, feedback forms and usability tests produce qualitative data that explains the numbers from your analytics tools. Analytics tells you where visitors drop off; feedback tells you why, which is what a good test hypothesis needs.

4How often should I run CRO tests?

CRO is an ongoing process, because there is always something to improve. How often you test depends on your traffic, since each test needs enough visitors to reach a reliable result, and on the size of the change. If your traffic supports it, keep at least one test running at all times and feed what you learn into the next test.

5Is CRO only for eCommerce sites?

No. eCommerce sites often focus heavily on CRO to lift sales, but any website with a goal can benefit. A blog can grow subscribers, a B2B site can generate more leads, and a nonprofit can collect more donations. The tools in this list work for all of them.

6Which tools from the original list no longer exist?

Several tools from earlier versions of this list have closed or changed. Skype was retired by Microsoft in May 2025 and replaced by Microsoft Teams Free. Mozilla shut down Pocket in July 2025. Beeketing no longer exists, and its domain now redirects to ShopBase. SmartBear discontinued CrossBrowserTesting in July 2023 in favor of BitBar. Formisimo is now called Zuko, UsabilityHub is now Lyssna, and Google Universal Analytics was replaced by Google Analytics 4.

7Is Google Optimize still available?

No. Google sunset Google Optimize and Optimize 360 in September 2023. Teams that used it moved to dedicated experimentation platforms such as Omniconvert Explore, which run A/B and multivariate tests and connect to Google Analytics 4 for reporting.

8Do I need all of these CRO tools?

No. Most teams need one tool per job: an analytics platform for the numbers, a feedback or user testing tool for the reasons, an experimentation platform to prove the fix, and a project tool to keep the work moving. Every extra tool adds cost, scripts and data to reconcile. An all-in-one platform that combines testing, surveys and personalization reduces the count.

Build the toolkit around the process

Tools do not make a CRO program; the process does. Pick one tool for each job, measure, listen, test, coordinate and create, and connect them so data flows from insight to experiment. Start with analytics and a feedback tool to find the problem, prove the fix with an A/B test, and keep the loop running. Successful optimization is not about attracting more traffic. It is about turning the traffic you have into meaningful outcomes.
