What it is
Microsoft Clarity records how visitors use your site: session replays, click and scroll heatmaps, and automatic flags for rage clicks, dead clicks and excessive scrolling.
It is free, with no session limits, which is remarkable given that Hotjar charges meaningfully for the same capability with caps attached.
Analytics tells you that a page converts at two per cent. Clarity shows you the eleven people who scrolled past your form without noticing it.
What it does
Session recordings play back real visits, including mouse movement, clicks, scrolling and form interaction. Watching ten of these teaches you more about a page than any report.
Heatmaps show where people click and how far they scroll, which reliably reveals that your key content sits below where most people stop.
Automatic insights flag rage clicks, where somebody clicks repeatedly in frustration, and dead clicks on things that are not links. Both point straight at broken expectations.
Filters let you watch only sessions that converted, or only those from a particular campaign, which turns a pile of recordings into an investigation.

| PLAN | WHAT YOU GET | WORTH IT FOR |

| Free | Everything, with unlimited sessions. | Every site. |
| No paid tier | There is no upsell. | Genuinely free. |
| Setup cost | A script on the site. | Ten minutes. |
| Privacy configuration | Field masking and a policy note. | Do this properly. |
Free with no limits and no paid tier. Configure field masking so you are not recording anybody's personal data.
Install it, mask sensitive form fields, then watch ten recordings of people who reached your contact page and did not submit. That exercise has changed more pages for me than any audit.

My verdict
Clarity is the most underused free tool I know of. Session recordings and heatmaps with no limits, at no cost, and most businesses have never installed it.
The reason it matters is that conversion problems are almost never what you assume. I have watched people miss a form because it sat below a large image, click repeatedly on a heading that looked like a button, and abandon a checkout at a field asking for information they did not have.
Install it this week, mask your form fields, and watch ten sessions. It takes twenty minutes and it will change something.
