How it works
One tag in. A ranked list of fixes out.
Cortality watches how real visitors use every part of your page, turns it into the few changes most likely to win you customers, and re-measures each one you ship.

Your Fix List in the dashboard. Findings from real client reports; the site name and dates are samples.
From install to proof
What happens, week by week.
Paste one tag
One line in your site’s head, added by you or your developer. Works with Shopify, WordPress, Webflow, single-page apps and custom builds. The setup screen confirms it’s live.
Day 0 · about 5 minutes
Real visitors, every element
Where people look, scroll, tap and stop, on every headline, image, button and form field. Measurement starts with your next visitor.
Days 1–7 · free
Your first report
Once your site has 100 visitors, you get your biggest leaks in order. Each comes with the number behind it, the reason, and the exact change to make.
About day 7
Proof it worked
Tell us when a fix ships and we compare before and after on the same instrumentation. Then the next fix comes, weekly or monthly depending on your plan.
Every week or monthWhat you get
The money math your analytics can’t see.
If a third of your visitors never see your buy button, a third of your ad spend is wasted. Page-level analytics don’t show it element by element. We measure it.
Every element, ranked
Every part of your page, ranked by the attention it really gets. Numbers, not color blobs. See it in the Page X-ray.
The Fix List
Your biggest leaks, in order. Each one comes with the measured evidence, a plain reason, and the exact fix. Click “Show on the page” to see where.
A report and a dashboard
A report you can forward to your team or developer, and a dashboard you keep: overview, page X-ray, and an anonymous session viewer on Growth and up.
The Re-Measure: proof, not opinion
Every fix you ship is measured on your next visitors, with a plain verdict:
Keep your other tools
Analytics tell you what happened. We tell you what to change.
Cortality works alongside Google Analytics and Microsoft Clarity. It answers the question they leave to you.

How visitors moved between pages: where they came in, where they went, and where they left. Sample data.
Safe for your site
Your page never depends on us.
- One async tag that loads in the background, after your page.
- Error-isolated. If anything goes wrong inside it, it shuts itself off.
- Never changes how your page looks or works.
- Recording never stops at a plan limit. Go over and every visit is still measured.
Data & privacy
Private by architecture.
- We don’t identify visitors. No names, no contact details, no cookies. Each visit gets a random ID.
- Form values are masked on the visitor’s device before anything is sent.
- No camera, no microphone, and no browser permission prompts with the standard tag.
- Your raw data is yours. No other client ever sees it, and it is never sold.
Locations stop at the city. Each visit is an anonymous ID. Sample data.
FAQ
Common questions, answered plainly.
Is this different from tools like Google Analytics or Microsoft Clarity?
Yes, and it works alongside them. Google Analytics tells you what happened. Microsoft Clarity shows you recordings. We measure attention on each part of the page, tell you what to fix, and prove the fix worked. Keep your other tools.
Is this just another website audit in a PDF?
No. Every finding must have a real measured number behind it, from your own visitors, plus a plan to prove the fix worked. You never get “we think the hero is weak.” You get “1 in 14 visitors noticed this headline,” like the example.
Will the script slow my site down or break anything?
No. It’s one small piece of code that loads in the background, and if anything goes wrong inside it, it shuts itself off. Details in the docs.
Do my visitors have to opt in? Is this privacy-safe?
Cortality sets no cookies. Form values are blanked on the visitor’s device before anything is sent. An optional random visitor ID stays off unless your site turns it on. Your privacy policy should disclose that you use Cortality, and whether you need visitor consent depends on your jurisdictions; Cortality works with consent tools. The full statement and draft policy language are in our Trust Center.
How much traffic do I need?
Your first report goes out once your site has 100 visitors. If it doesn’t reach that by day 30, the trial ends and you’re never charged. Cortality is built for sites too small to run A/B tests to significance.
