The best CRO Tools to Increase Your Conversions

The online business space is super competitive. It is so competitive that simply getting noticed can feel like an accomplishment. With millions of websites and businesses vying for attention, securing any visibility feels like a win.

Honestly—maybe it is, but visibility is just the first step.

But here’s the bubble buster: visibility alone won’t get you to your goals.

Imagine you’ve driven traffic to your site—great. But what happens next? Do visitors engage, sign up, or make a purchase? If they don’t, all that traffic is just a missed opportunity.

While traffic brings you visibility, conversion is the key that unlocks your business success—whether that’s making sales, gathering leads, or getting users to take specific actions.

But conversion isn’t something you can fix with a few vague tips or tweaks. You’ll find endless advice out there, from redesigning your CTA buttons to optimizing landing pages, but the reality is that without the right tools, you’re flying blind.

You need data to show you what’s happening, and you need tools to help you fix it. Conversion Rate Optimization (CRO) tools can provide both the data and direction you need to make those fixes.

In simple terms, CRO tools provide real-time insights, diagnostics, and actionable strategies to turn traffic into conversions.

This blog is here to help you navigate the crowded CRO landscape and identify the best tools that will give your business the conversion lift it needs.

Let’s dive.

1. Seline

Seline is a powerful, privacy-conscious web analytics tool that gives you the data you need to make decisions that boost your conversion rates. It is a stand out solution for those who need detailed insights into how their online business website is doing without the headache of overly technical platforms. Unlike more complex tools such as Google Analytics, Seline is designed to provide actionable data in a user-friendly package.

To give you a better visualization of Seline—think of most of the things you can do with Google Analytics, but then think of being able to do it 10x faster and 10x easier. Despite offering detailed information on your website's performance, for Seline, simplicity and ease of use is a big theme. Whether you're just starting out or need to streamline your CRO process, Seline is built to help you optimize conversions with ease.

Key Features:

• User Behavior Analysis: Seline lets you track crucial user actions like where visitors are clicking, how long they’re spending on your webpages, and the paths they take through your site. This information is invaluable for understanding customer journeys and pinpointing where potential conversions are being lost.
• Funnel Analysis: One of Seline’s CRO features you'll love is its minimalist funnel analysis tool. If you've had to deal with unwieldy, complex funnel analysis tools, Seline is a breath of ease. Seline offers a straightforward solution that shows you exactly where users are dropping off in your sales funnel, which in turn gives you immediate clues on how you can make precise adjustments to capture those missed conversions.
• Free-to-Use Option: Best of all, Seline is free to use until you’re ready to pay, making it an excellent entry point for small to medium businesses.

Where other tools might require a steep learning curve or complex integrations, Seline keeps things simple without sacrificing depth. While big names in web analytics like Google Analytics might overwhelm you with too much data, Seline gives you exactly what you need to make informed CRO decisions.

2. Google Analytics

Irrespective of how complex it can get at times, no discussion about conversion rate optimization tools would be complete without mentioning Google Analytics. It’s one of the most popular and widely used analytics tools in the world. When you think about Google analytics, you can visualize it as a tool that gives you access to a massive amount of data that helps your businesses make informed CRO decisions. While it's often criticized for its complexity, confusing layout and steep learning curve, when you overcome these limitations, Google Analytics can be a very powerful, even indispensable CRO tool.

Key Features:

• Massive Analytical Data: Google Analytics offers an exhaustive amount of data on virtually every aspect of your website’s performance. From user demographics to real-time traffic, it tracks and reports everything you could possibly want to know about how people are interacting with your site.
• Conversion Tracking: The platform provides robust tools for tracking specific conversion goals, such as sign-ups, downloads, or purchases. This helps you see which pages and paths are leading to conversions—and which ones aren’t.
• Integrations with Other Tools: Google Analytics integrates seamlessly with many other platforms. It plays nice with Google's massive ecosystem of web related tools, so that's one of the perks you get for using Google analytics.

Should you use Google Analytics? It's a really good CRO tool, but the devil is in the detail. You really need to know what you're doing to make the best use of the tool and knowing what you're doing takes a bit of time. That's why it might be a good idea to pair tools like Google with easier-to-use options like Seline. With that, you can get the best of both worlds: the sheer data power of Google with the streamlined, actionable insights of Seline.

3. FullStory

FullStory is a powerful tool designed to give you a full picture of how users interact with your digital platforms. That description might sound like it's just another web analytics tool, but not really. FullStory takes a different approach to conversion rate optimization. Rather than focusing on the type of web metrics you get from tools like Google analytics and Seline, it focuses on visualizing user behavior across channels, with emphasis on visualization. It's a reliable CRO tool for businesses that want to get a visual reconstruction of user interactions on their website and identify areas for optimization.

Key Features:

• Session Recordings: FullStory allows you to record entire user sessions, providing a play-by-play of how people are navigating your website or app. This feature helps you see exactly where users may be getting confused, frustrated, or lost, making it easier to pinpoint areas that could improve conversions.
• Heatmaps: FullStory offers heatmaps to visually highlight where users click, scroll, and hover. This helps you understand which areas of your site are getting the most attention and which are being ignored.
• User-Level Analysis: Unlike some tools, FullStory focuses on indexing individual user interactions. This enables you to drill down and analyze specific user experiences to understand why certain behaviors occur.

While FullStory gives you a broad view of digital user behavior, the data can sometimes be complex and challenging to act on quickly. Compared to tools with simpler metrics, FullStory requires more time and analysis to understand. For those who want detailed interaction tracking, possess the technical skills and have enough time on their hands, FullStory is undoubtedly a great choice.

4. Hotjar

Hotjar is another CRO tool that focuses on visual insights into your web metrics. It is a go-to tool for understanding how users are interacting with your website on a more qualitative level. While a lot of web metrics style CRO tools focus on quantitative data, Hotjar excels in giving you a visual representation of user behavior. Although similar in some ways to FullStory, you'll find Hotjar a bit easier to deploy and navigate. As a result, you'll be able to easily identify what's working and what’s not when it comes to conversion rate optimization strategy.

Key Features:

• Heatmaps: Hotjar’s heatmaps show exactly where users are clicking, scrolling, or pausing on your site. This helps you visually see which elements are attracting attention and which parts are being ignored. By analyzing these areas, you can optimize your layout to improve user engagement and conversions.
• Session Recordings: Hotjar’s session recordings allow you to watch real-time user interactions as they navigate through your site. You'll find it incredibly useful for spotting potential issues or bottlenecks in your user experience.
• Feedback and Surveys: Hotjar also offers tools to gather feedback directly from users, helping you understand why certain behaviors are happening. With easy-to-deploy surveys and feedback widgets, you can collect real-time insights to improve your conversion funnel.

When compared to tools like FullStory, Hotjar seems like the better option in terms of ease of use. However, Hotjar is still a tough nut to crack when it comes to really understanding its key features and making the best of the tool. While it highly rated when it comes to providing robust and excellent visual insights, being able to unearth those excellent insights requires a steep learning curve. For users looking for simplicity and quick data-driven actions, Hotjar is probably not what you want.

5. Crazy Egg

Crazy Egg is another powerhouse you might need to add to your conversion rate optimization toolkit. It offers a suite of visual analytics tools that help you understand the “how” and the “why” behind your visitors' interaction with your website. How would we rate Crazy Egg? It's definitely a solid tool and is simpler to use if you know what you want to achieve and stick to it. But it is easy to wander off, get stuck in the complexity and lose track of your core goals. Why? Well, it does come with a lot of interesting tools and data points, some of which you might probably never use throughout the life cycle of your web business. If you’re a fan of Seline’s simplicity but want to enhance your CRO strategy with more visual insights, Crazy Egg is a great complementary tool.

Key Features:

• Heatmaps & Click Maps: Like Hotjar, Crazy Egg offers heatmaps and click maps that give you a clear picture of where users are engaging with your site. These visual tools make it easy to see what elements draw the most attention and where users are losing interest.
• Scroll Maps: With scroll maps, you can track how far down users are scrolling on your pages. This is particularly helpful for determining if important content or calls-to-action (CTAs) are being overlooked because they’re placed too low on the page.
• A/B Testing: One standout feature of Crazy Egg is its built-in A/B testing. You can experiment with different versions of a page and see which one converts better, allowing you to optimize your site based on real data. Plus, its user-friendly interface makes it accessible even if you’re not particularly tech-savvy.

While Crazy Egg offers simple and robust visual analytics, it still lacks that simplicity and streamlined experience that we've come to appreciate with new generations of web analytics tools. However, for those looking to run A/B tests with detailed visual data, Crazy Egg offers excellent value.

6. Optimizely

Optimizely is a well-known name within the CRO ecosystem, especially for businesses looking to dive deep into experimentation. It’s primarily focused on A/B testing and multivariate testing, making it a big name among marketers and developers who are serious about optimizing their websites. The emphasis here is on seriousness. Optimizely packs quite a punch, but considering the cost (over $30,000 yearly) and the technical debt required, we'll recommend only if you are running a complex online business that requires multidimensional data to crack. Sure, you can still use it for your average online business website, but is it really necessary? Probably not.

Key Features:

• A/B and Multivariate Testing: Optimizely shines in its ability to run multiple experiments at once. Whether you want to test different page designs, layouts, or CTA buttons, this tool can handle complex tests that give you detailed insights into what works best for your audience. If you’re just starting with A/B testing, though, it is not entirely the best option for beginners.
• Personalization Capabilities: One of Optimizely’s key strengths is personalization. You can customize web experiences based on user segments, such as new vs. returning visitors or users from different regions. This feature is powerful for tailoring content and improving conversions for specific audiences.
• Developer-Friendly: Optimizely caters to a more technical crowd. It requires some coding skills, especially when running advanced tests, which makes it ideal for larger teams with dedicated developers.

Though Optimizely provides in-depth testing capabilities, it comes with a higher learning curve and cost. If you have the budget, and the need, by all means, go for it—optimizely is a solid CRO tool.

7. Adobe Analytics

If you've been in the CRO and web analytics game for a while, you are probably familiar with Adobe Analytics. But if you're not, that's okay—Adobe Analytics is a powerful tool that offers robust tracking and analysis of real-time data across multiple channels. It is an excellent choice for businesses that want a comprehensive understanding of their customers’ journeys, from web to mobile to email. Adobe Analytics is feature-rich and a good option for businesses that have a considerable budget to spend on CRO and web analytics services. Pricing hovers around $2500 per month but to spike to around $100,000 annually for larger enterprises that use more tools and resources within the Adobe Analytics product suite.

Key Features:

• Multichannel Tracking: With Adobe Analytics, you can track user behavior across various sources, including your website, email marketing campaigns, and mobile apps. This multifaceted approach provides a holistic view of user interactions and helps identify conversion bottlenecks across platforms.
• Key Performance Indicators (KPIs): The platform allows you to set and measure KPIs tailored to your business goals. By monitoring these metrics, you can gauge the effectiveness of your marketing efforts and optimize accordingly.
• Visually Appealing Reports: Users often praise Adobe Analytics for its visually compelling reports that make complex data easier to understand. While the reports are sophisticated, you'll find them easy to consume and act on.
• Although Adobe Analytics offers a wide array of features and detailed insights, it comes with a steep learning curve. For those who prefer a more user-friendly option that still delivers valuable analytical insights, you'll find lots of easier alternatives elsewhere.

8. Heap Analytics

Heap Analytics is another popular tool for web analytics and conversion rate optimization. It automatically captures user interactions across your website and mobile applications. This eliminates the need for manual tracking, making it a valuable asset for businesses looking to gain insights without the technical hassle. However, it has a lot of well documented quirks. Notable among them is the fact that it doesn't really have an engagement layer. Which in simple terms means it doesn't give you the tools to act on the insights you get from the data it provides. Considering its price, this should be a no-brainer. And of course there's the all too common issue of steep learning curve and high deployment cost. Let's not even get started with the loads of data you have to keep track of because it captures stuff automatically! It's a good tool alright, just with a long list of annoying baggage.

Key Features:

• Automatic Event Tracking: One of the standout features of Heap is its ability to automatically track every user interaction—clicks, page views, form submissions, and more—without requiring additional configuration. This comprehensive data collection allows you to analyze user behavior effortlessly.
• User Journey Mapping: Heap provides advanced user journey mapping tools, helping you visualize how users navigate through your site. This functionality helps identify friction points in the conversion funnel and understand where users drop off.
• In-depth Analytics: With Heap, you can dive deep into user behavior analytics and segment your audience based on interactions. This detailed approach allows for targeted optimizations but may require more time to set up and analyze compared to

In summary, while Heap Analytics offers powerful features for automatic tracking and in-depth analysis, it comes at a cost— unnecessary complexity and sky-high prices, something that may deter some users.

Conclusion

When it comes to CRO tools, there are plenty to choose from, each with its own unique strengths.

• Google Analytics delivers detailed data points, but its complexity can be overwhelming.

• Optimizely offers powerful A/B testing features but comes with a steep learning curve and higher costs.
