15 Best Conversion Rate Optimization Tools to Get The Most Out of Your Website

Ever felt like your conversion rates are playing hard to get? The issue might be hiding in plain sight. It might be because your “Sign up” or “Buy now” buttons aren’t catching users’ eye. Or maybe your website is a bit hard to navigate – users can’t figure out where to go next. And those forms you want people to fill out? If they’re too long or confusing, users might say, “Nah, too much work” and leave. 

And don’t get me started with those SaaS landing pages where  figuring out what the software is all about feels like solving a puzzle.

Or maybe, it’s more subtle things, like smaller fonts or somewhat unclear copy. There are many things you need to keep an eye on to achieve high conversion rates, right? That’s what conversion rate optimization (CRO) is for. 

In this post, I wanted to talk about  e 15 conversion rate optimization tools (+ their features, pros, and cons) that will help you tackle pretty much every aspect of the CRO process.

What are the Different Types of CRO Tools?

CRO tools come in various types. It could be behavior analytics tools, A/B testing tools, email marketing tools, and others. These tools contribute to different aspects of CRO by giving insights into user behavior, optimizing web page variations, and enhancing email campaigns.

Below, I’m getting into the nitty-gritty of the 15 best CRO tools that we at Mouseflow have tried, breaking down what they do and how to use them to achieve higher conversion rates.

Behavior Analytics Tools

Behavior analytics tools are almost the most important ones for building a successful CRO program. They provide you with information about what your users do on your website, how they do, and give an idea about why they behave that way.

Check out our Executive Guide to Behavior Analytics if you’re new to behavior analytics.

1. Mouseflow

Mouseflow conversion funnel example

Mouseflow (yes, that’s us, and we use our own tool for CRO on a daily basis!) is a user experience optimization and web behavior analytics tool that provides website owners with insights into user behavior on their websites. Mouseflow allows users to record and analyze visitor sessions, track clicks, mouse movements, scrolls, and form interactions.

Mouseflow is particularly useful for eCommerce businesses. Online retailers use Mouseflow to analyze how users navigate through their website, where they drop off in the sales funnel, and what elements may contribute to higher conversion rates. Similarly, CRO specialists use Mouseflow to monitor their most important pages, forms, funnels, surveys, traffic sources, and more from personalized dashboards.

Key features

  • Session replays: Mouseflow’s session recording feature provides a treasure trove of insights into the intricacies of user behavior on your website. By capturing the actual screens users view and recording their entire sessions, Mouseflow offers you a detailed play-by-play of how visitors navigate your site. Using session recordings, CRO specialists can see firsthand how visitors move from one page to another, and where they might encounter friction in the user journey.
  • Heatmaps : Mouseflow has 6 types of heatmaps, which offer a graphical representation of users’ activity on the page: where they click, how they scroll, etc. 

    Let me give you an example of how heatmaps can help with CRO. While exploring a small online store some time ago, I ran into a problem trying to find a specific type of backpack. I clicked on “Outdoor Gear,” thinking it’d lead me to backpacks, but I ended up in a section with camping equipment instead. The issue was that the backpacks were tucked away under a more general category. The problem was that what I wanted was there, but the way the website organized things made it tricky to locate. Mouseflow’s heatmaps could have helped by showing exactly where users like me were getting stuck.

  • Conversion funnels : Mouseflow’s conversion funnels feature allows tracking website  conversion rates at each step and comparing user journeys. For CRO specialists, they offer not only the quantitative data and a good visual asset to show to stakeholders, but also the option to check out recordings of users who completed or abandoned the journey. The real benefit of that feature is that you can see what pages contribute most to your conversions if your blog posts or help articles are converting visitors, and the exact moments where many users drop off.
  • Form analytics : I bet you’ve asked yourself, “What’s wrong with my checkout page? Why don’t people finish filling out my forms? Solving that issue can be a real head-scratcher. Mouseflow automatically identifies your forms and starts tracking. It tags user session recordings with form interactions, and understanding the nuances of user engagement becomes much easier. So, now you can figure out what keeps your visitors engaged and make your forms super user-friendly.

Cons

  • Feature complexity: Mouseflow has many practical features, but it might take a bit to get the hang of them all.
  • Restricted dashboard customization: The dashboards offer limited customization, especially concerning specific landing pages or sources. So, more flexibility in customizing reports would improve the user experience.

Pricing

As mentioned, there’s a free plan with 500 recordings a month. When it comes to paid plans, Mouseflow pricing starts from $39/month, giving you up to 5,000 recordings each month. Plus, you get 3 months of data storage with that plan. Check out Mouseflow’s pricing page. for all the nitty-gritty details.

Quantitative Website Analytics Tools

Quantitative analytics tools are more familiar to the general public. For CRO, they are often the starting point for hypothesis development. With a quantitative analytics tool, you can see that some metric dipped somewhere, and then, using behavior analytics, you can get deeper insights into why that happened.

1. Google Analytics 4

  • Behavior flow analysis: See how users move through your site and where they drop off in the conversion process. Behavior flow reports show the paths users take, allowing you to identify potential bottlenecks and areas for improvement.

Pros

  • Comprehensive data collection: Google Analytics provides a wide range of data on user behavior, traffic sources, conversions, and more.
  • Real-time reporting: Google Analytics provides real-time reporting, allowing users to monitor website activity as it happens.

  • Lack of context: Google Analytics provides data, but it doesn’t provide the context needed to understand why certain patterns are occurring. So, users might need additional context to make informed decisions.

Pricing

A/B Testing tools

CRO’s bread and butter – CRO as a discipline would’ve been impossible without these. Modern A/B testing tools offer much more than just split testing and comparing results. When it comes to picking 3 favorite ones, we’d settle with these:

1. Convert

Convert screenshot
Convert is a comprehensive testing suite for A/B, multivariate, and split URL testing. This A/B testing tool includes a WYSIWYG (what you see is what you get) editor, making it the easiest way to set up an A/B test.

Key features

  • Audience targeting engine: Use presets designed for popular audience segments, considering factors such as location, language, device, and time of day. Plus, you can use a conditions builder with 40+ filters, letting you target audiences using JavaScript conditions, UTM parameters, experiment ID, and custom tags.
  • An extensive list of integrations: Benefit from Convert’s over 90 integrations. That way, you can gather and transmit data across almost every component of your existing setup. For instance, Convert integrates with Mouseflow.

Pros

  • Real-time reporting: Convert’s real-time reporting feature is highly effective, and it offers great interactive graphs that enable quick adjustments.
  • Smooth loading: Convert stands out as one of the fastest A/B testing tools as it offers a seamless loading process without any flickering.

Cons

  • Could seem expensive: The starting plan is $499 per month (when billed monthly), which might seem on the higher side. It’s not that other well-known tools are cheaper, it’s just that good A/B testing platforms are expensive in general.
  • Complex UI: Although the current interface is user-friendly, there’s still room for simplification to make it even more intuitive.

Pricing

Convert’s pricing is determined by the volume of traffic you generate. The basic plan, offering unlimited tests, is priced at $499/month.

2. Kameleoon

Here’re 3 of them that we either use now or our colleagues used earlier and liked. 

1. HubSpot

Landing Page Builders

While so many people pay so much attention to optimizing campaign spend, only a fraction of them look at optimizing the post-click experience. That’s effectively CRO for landing pages, and it can make a huge difference in campaign results. The things you can do with your landings depends heavily on which landing page builder platform you choose. 

We ourselves use WordPress and Hubspot for our landings, but it’s because we rely on them a lot in other parts of our tech stack such as email automation and our website. If we were to choose a standalone landing page builder, we would’ve likely chosen one of these three because of their flexibility and functionality: 

1. Unbounce

Unbounce screenshot
Unbounce is a cloud-based platform that provides tools for creating and optimizing landing pages and website pop-ups.

Key features

  • A/B testing: Optimize your campaigns by comparing different versions and see the most effective elements.
  • AI-powered landing pages: Unbounce lets you design landing pages down to the pixel combined with its AI-powered recommendations. Besides that, you can design unique landing page elements using JavaScript and CSS.

Pros

  • Lots of landing page templates: The landing page builder is really easy to use and makes it easy to build nice-looking landing pages that are mobile responsive.
  • Drag-and-drop functionality: The drag-and-drop thing makes building pages super easy, so you’ll get the hang of it real quick.

Cons

  • Hard to get responsiveness right: The platform works fine for standard mobile and desktop resolutions, but it’ll take a while if you want some elements to move when displayed in a half-size window, for example.
  • Slow performance: Sometimes it takes a little longer to perform certain functions on the platform, making it a bit frustrating to use.

Pricing

As mentioned, Unbounce’s pricing starts at $99 per month (but you can get a 20% discount if you register via G2), and with that, you get unlimited landing pages and popups.

2. Instapage

Instapage screenshot
Instapage is a platform that allows users to create landing pages. Its most common use cases include eCommerce, lead generation, and retargeting.

Key features

  • A/B testing: Make different versions of your landing pages to see what layout, text, and images connect best with different groups of users.
  • Heatmaps: Check out heatmaps to see where people are moving their mouse, clicking, and scrolling on your page. It helps you figure out what’s effective and what you should test to make your page even better.

Pros

  • Flexible and fast: Instapage offers a flexible and speedy platform for creating landing pages, allowing users to customize designs to their needs efficiently.
  • Pre-built templates: The availability of pre-built templates simplifies the page creation process, providing a starting point for users who may not have design expertise.

Cons

  • Limited dynamic content functionality: Instapage lacks advanced dynamic content features that adapt based on traffic sources or user behavior
  • Expensive: The cost of using Instapage is relatively high, which might be a drawback for budget-conscious CRO teams.

Pricing

The basic Instapage plan is priced at $299/month, but – a heads up – you won’t get heatmaps and many third-party integrations with that plan.

3. Landingi

Landingi screenshot
Landingi is a drag-and-drop platform to create and optimize landing pages for marketing campaigns.

Key features

  • Event tracker: Keep tabs on everything happening on your landing pages with Landingi’s event tracker. It automatically collects data, which you can access directly from your dashboard.
  • A/B testing: Compare different versions of your landing pages by changing just one element. This helps you gather data on which variant performs better.

Pros

  • Easy-to-use: Landingi offers an easy-to-use drag-and-drop interface that allows users without technical expertise to create landing pages.
  • Affordable: Landingi is way cheaper than Instapage and Unbounce, kicking off at just $29/month.

Cons

  • Inconsistent responsive layout: The responsive design can be cumbersome. It may occasionally demand significant adjustments when moving elements across various screen sizes.
  • Unexpected logouts: Watch out for surprise logouts and the occasional failure to save your work, as you might need to log in again and risk losing some of your work – that’s what happened to some users who left reviews on Capterra.

Pricing

Landingi costs either $29/month or $240 for the whole year if you pay upfront annually.
