Google Analytics 4 gives you numbers, but rarely the reason behind them. To understand why a page underperforms, you need to see what visitors actually do: where they click, where they stop reading, and when they get frustrated. We compared four website tracking tools we use ourselves or install for our B2B clients: PostHog, Klickbee Tracking, Matomo and Microsoft Clarity. For each one: what it does, what it costs, what it means for privacy compliance, and who it is for.
Disclosure: Klickbee Tracking is the tool we built. To stay objective, we scored it with the same grid as the other three, and it does not come first: PostHog remains the most complete platform. Klickbee Tracking is, however, our pick for a B2B or e-commerce site that runs ads and wants replays, heatmaps and server-side conversions without a cookie banner for audience measurement.
We looked at each tool through the questions a B2B marketing leader asks, not a developer:
Klickbee Tracking screenshots come from our own account on klickbee.com. Matomo, Clarity and PostHog screenshots come from their public demos and official websites. Prices are those listed on each vendor's website in October 2026.
The criteria that matter for a B2B site, tool by tool, with our score out of 5:
PostHog is a suite for product teams: event analytics, session replays, feature flags, A/B tests, surveys and a data warehouse. Its code is public and it offers EU hosting.
Free up to 1 million analytics events per month and 5,000 web session recordings per month. Beyond that, usage-based pricing that drops with volume.
SaaS companies with a product team and developers. On a B2B marketing site, its depth quickly turns into complexity: you have to define your events, and privacy configuration (cookies, consent) is on you.
Klickbee Tracking puts into one script what usually takes three tools: audience measurement, behavior analytics and sending conversions to ad platforms. Klickbee sets no cookies and does no fingerprinting, so audience measurement runs without waiting for consent; only your ad pixels wait for the visitor's opt-in.
The AI summary above comes from a real session on our site: the tool spotted two dead clicks on a form, inferred the visitor's intent ("requesting a free audit") and scored the friction at 72 out of 100. That is exactly the kind of problem a GA4 report never shows.
B2B and e-commerce sites running ads that want to know why their pages convert, without stacking GA4, Hotjar, a tag manager and a cookie banner. We cover every feature in our complete Klickbee Tracking guide.
A newer tool: fewer integrations than PostHog and no self-hosting. A/B tests need one line of code on your site.
Matomo is the go-to tool for replacing Google Analytics while owning your data. It looks and works like classic web analytics: visits, sources, pages, goals, e-commerce. It can be configured to run without cookies, which in some jurisdictions lets you measure audience without consent.
Organizations moving off GA4 that want familiar reports and full data ownership, especially in the public sector and healthcare. Self-hosting needs a server and some maintenance, and the interface is dense for a small marketing team.
Clarity is free with no traffic limit. It offers heatmaps, replays and frustration metrics (rage clicks, dead clicks, excessive scrolling), plus an AI assistant that summarizes sessions.
Free.
A quick first diagnosis on a site that has never been analyzed. For European traffic: Clarity sets cookies, and since October 31, 2025 Microsoft requires a valid consent signal for visitors from the European Economic Area, the UK and Switzerland. Without it, Clarity stops collecting data for those visitors, so your heatmaps only cover part of your traffic. Data is hosted by Microsoft in the United States.
The most common mistake we see with clients: stacking GA4, Clarity, a tag manager and three ad pixels with no defined goals. The result is a cookie banner refused by one visitor in four, conversions that never reach Google Ads, and nobody watching the replays. One well-configured tool with five clear goals beats four tools wired together badly.
It depends on what you need. Matomo is the closest to GA4 in terms of reports. Klickbee Tracking goes further on behavior (replays, heatmaps, frustration) and ad conversions, without cookies. PostHog is better suited to analyzing a SaaS product.
Yes. Klickbee Tracking sets no cookies for audience measurement, and Matomo can be configured without cookies. Ad pixels (Google Ads, Meta, LinkedIn) do set cookies and still need consent, whatever analytics tool you use.
Clarity sets cookies and transfers data to Microsoft. Since October 31, 2025 it must receive a consent signal for European visitors, otherwise it does not collect their data. It can be used lawfully with a properly configured consent banner.
PostHog if you analyze a product (app, SaaS) with a technical team. Matomo if you want classic web reports close to Google Analytics and control over hosting.
Not for Klickbee Tracking, Matomo Cloud or Clarity: one script in your site's head, or a WordPress plugin. PostHog and self-hosted Matomo need more technical setup.
