The best conversion rate optimization tools of 2026

For many sites the first conversion that matters is an email address, and Convertful's strength is targeting those sign-up forms by what your email platform already knows. It reads tags, lists and custom fields from ActiveCampaign, HubSpot, Klaviyo, Mailchimp, Kit, AWeber, Drip, GetResponse and others. People already on your list stop seeing your newsletter pop-up, and someone tagged as a buyer of one product sees the offer for the next.

You get pop-ups, scroll boxes, floating bars, fullscreen welcome mats, inline forms and floating buttons, plus on-site surveys and simple quizzes. Triggers include exit intent, scroll, time on page, clicks and inactivity, and you can A/B split test widgets from Starter up. More than 100 templates give you a starting point.

Starter costs $17 a month billed yearly, or $29 monthly, for 3 sites and 25,000 pageviews, with two-way CRM sync, A/B testing, AI features and no Convertful branding. Solo ($84 a year, or $9 monthly) covers one site with branding. Every plan has a 14-day trial and a 14-day money-back guarantee.

Choose it if you segment your email list with tags and want the forms on your site to use that data.

Skip it if you want a free plan or the biggest template library. Our pop-up builder guide compares those options.

Clarity is where most sites should start, because it costs nothing and Microsoft sets no traffic limit. Once its tracking code is on your site, it records visitor sessions and builds heatmaps that show where people click, how far they scroll and where they leave. Ten recordings of shoppers giving up on your checkout page can point to the fix faster than a month of traffic reports.

The AI features help on busier sites. Clarity writes summaries of behavior trends across a page, and its Copilot chat answers questions about your data, so you can find a pattern without watching hundreds of sessions yourself.

Clarity shows you the problem but has no way to test a fix. For that you need one of the testing tools below, or a page builder like Unbounce.

Choose it if you have never watched how visitors use your site, or you want recordings on a high-traffic site without paying per session.

Skip it if you want surveys and analytics in the same account. Contentsquare and Crazy Egg combine both.

Hotjar is now part of Contentsquare. You can no longer open a new Hotjar account, and hotjar.com sends you to Contentsquare, which has folded Hotjar's heatmaps, recordings and surveys into its own plans.

The free plan is generous on capture and tight on replays. It records up to 200,000 sessions a month with heatmaps, attention maps, funnels and error monitoring, but keeps session replays for only 5% of sessions (10,000 at most) and holds your data for one month. It also includes 100 survey responses a month, which is how you learn why people leave, alongside where. Slack, Jira and Unbounce are among its 10+ integrations, and it can connect to an AI assistant through MCP.

Growth costs $39 a month billed yearly, or $49 month to month, at the entry session level, rising with traffic. It keeps 13 months of data and covers 3 projects. Pro and Enterprise are custom quotes. New accounts start with a 15-day Growth trial with no card and drop to the free plan afterward unless you choose to pay.

Choose it if you want behavior data and visitor feedback in one place, or you used Hotjar and want its successor.

Skip it if recordings are all you need. Clarity records them free with no traffic limit.

Crazy Egg puts behavior analysis and testing in one place. Every plan includes heatmaps, session recordings and unlimited surveys, and from Plus up you also get unlimited A/B tests, so you can spot a problem on a heatmap and test the fix without adding a second tool. It also covers error tracking, web analytics and pop-up calls to action.

Prices are per month, billed yearly. Starter costs $29 a month for 5,000 pageviews, 50 recordings and 5 heatmap reports, enough to study a few important pages, though it has no A/B testing. Plus, at $99 a month, is the plan most sites will want: 150,000 pageviews, 1,000 recordings, 75 heatmap reports and unlimited tests. Pro ($249) raises that to 500,000 pageviews and 5,000 recordings, and Enterprise ($599) to 1,000,000 pageviews. Every plan starts with a 30-day trial. Crazy Egg says more than 449,000 websites use it.

Choose it if you want one dashboard that shows what visitors do and whether your change helped, at a lower price than a dedicated testing platform.

Skip it if you need recordings of most sessions on a busy site. Plus caps you at 1,000 recordings a month, while Clarity sets no limit.

Convert is the testing tool to pick once A/B testing becomes a regular part of your work. It runs A/B, split URL, multivariate and multi-page funnel tests, plus multi-armed bandit tests, price tests and personalization, and it connects to more than 100 other tools. Convert says its SmartInsert script stops the flicker you sometimes see when a test swaps content after the page loads, and that comes on every plan.

Privacy is a second reason to choose it. Convert uses first-party cookies only, stores data on servers in Frankfurt, Germany, and says it doesn't need to store personal data to run tests, which helps if your legal team reviews every script on the site.

Convert also publishes its prices, which most testing platforms don't. Growth costs $299 a month billed yearly ($3,588), or $399 month to month, for 100,000 tested users a month. Pro costs $420 a month billed yearly, or $599 monthly, and adds single sign-on. Extra traffic on Growth costs $399 per 100,000 users. The 15-day trial needs no card.

Choose it if you run several tests a month and want clear pricing and EU data storage.

Skip it if your site gets a few thousand visitors a week. Tests take a long time to reach a result at that traffic, and $3,588 a year pays for a lot of Crazy Egg.

VWO and AB Tasty have combined their platforms under the Wingify name, and VWO's old pricing address now redirects to wingify.com. The merged product covers experimentation, personalization, feature management, behavior analytics (heatmaps, recordings, funnels and surveys), commerce search and recommendations, and browser push messages, with an AI layer called Wingz AI across them. Wingify says it has more than 4,000 customers.

You can start with one product and add others later. Each comes in Growth, Pro and Enterprise plans, which differ in workspaces and domains (1, 3 or 5) and in how fast support first replies (8, 6 or 4 hours). Wingify publishes no prices, and every quote is custom. The free trial lasts 30 days and needs no card.

Choose it if you're a marketing or product team that wants testing, personalization and analytics from one vendor, or you already run VWO or AB Tasty.

Skip it if you want to know the price before a sales call. Convert publishes its prices and covers most of the same test types.

Most tools on this list measure or test pages you already have. Unbounce is for building new ones: landing pages for ad campaigns and offers, drafted by its AI from a description, started from a template or built from a blank page, then edited with drag and drop. Every plan includes unlimited conversions and subdomains, and pages connect to Google Analytics, HubSpot, Mailchimp, Salesforce, Zapier and webhooks.

Testing depends on the plan. Starter ($29 a month) and Build ($99 a month) publish pages but don't A/B test them. Experiment ($112 a month billed yearly, $149 monthly) adds A/B testing for up to 30,000 visitors on 2 domains. Optimize ($187 a month billed yearly, $249 monthly) adds Smart Traffic, which uses AI to send each visitor to the page variant they're most likely to convert on, for up to 50,000 visitors on 3 domains. Agency plans start at $349 a month. The trial lasts 14 days and needs no card.

Choose it if you run paid ads and want a page for each campaign that you can test without a developer.

Skip it if you want to test changes to your existing website or store. Convert or Crazy Egg run tests on the pages you already have.

OptiMonk is the cheapest way to start testing pop-ups and offers on an online store. The free plan covers 10,000 pageviews a month on one domain with 1,000 AI credits a month, and OptiMonk says there are no feature gates between plans, so A/B testing and targeting come with it. You don't need a card to sign up.

Its AI agent does much of the work. You describe the campaign you want, and the agent designs, writes and publishes it, then runs A/B tests and offers to roll out the winner. You can also edit by hand in the visual editor or start from a library of more than 1,000 pop-ups, including exit-intent discounts, spin-to-win wheels, scratch cards and quizzes.

OptiMonk lists 62 integrations, including Shopify, WooCommerce, BigCommerce, Magento and Wix on the store side and Klaviyo, Mailchimp, HubSpot and Omnisend for email.

Paid plans buy more pageviews and domains. Essential is $19 a month billed yearly, or $29 monthly, for 20,000 pageviews on 2 domains. Growth is $69 billed yearly, or $99 monthly, for 100,000 pageviews on 4 domains.

Choose it if you run a store and want to test offers to visitors before you pay anything.

Skip it if you run a busy content site. Pricing counts every pageview, so 500,000 a month means Premium at $179 a month billed yearly.
