Explain it like I'm five
A tiny helper that watches, checks and learns.
It checks
Every time someone opens a page, it checks eight search-engine basics — like a missing title or a picture without a description.
It learns
Give it two or three versions of a headline. It shows them in turn and learns which one gets more people to act.
Think of it like
A shop assistant with a clicker and a clipboard: counts who walks down each aisle, notes when someone jiggles a stuck door, checks every price tag is on, and tries two window signs to see which brings more people in. Never asks anyone's name.
How it works
Paste. Listen. Compete. Learn.

Try it · right here
Be a frustrated visitor for ten seconds.
Pulse notices when people click the same spot again and again, or click things that aren't clickable. Go on — annoy it.
Test areaListening
…or click this plain sentence. It looks like it should do something. It doesn't.
Scroll this box. Pulse records scroll depth at 25, 50, 75 and 100 percent, so you learn where readers give up.
Most people never reach the bottom of long pages. Knowing where they stop tells you where the important part should go.
Keep going…
Almost there…
You made it to 100%. Most visitors don't.

Demo only: this stays in your browser. On your site, Pulse sends events like these (never names, emails or form contents) to your portal.
Side by side
Three tools' jobs. One free line.
Speed signals, frustration clicks and an SEO check on every real page view usually mean stitching tools together. Pulse does all three, free, without a single cookie.

Where Pulse wins
Nothing else in this list checks your SEO basics on every real page view — and Pulse does it in the same free, cookieless line that measures speed and frustration clicks.
Where it doesn't
No session recordings, no heatmaps, no ad attribution. Keep Clarity or GA4 for those — Pulse sits happily next to them.

Questions, answered straight
The honest Q&A.
Is it really free?
Yes — the Pulse tier is free: speed and frustration signals, the SEO sentinel, manual headline variants and the dashboard. Automatic promotion of winning copy, SEO fix suggestions, anomaly alerts and the weekly report are on the paid Brain tier.
Does it replace Google Analytics?
Not fully. Pulse covers page experience, frustration signals, basic SEO hygiene and copy testing. It doesn't do acquisition-channel attribution, funnels, audiences, e-commerce revenue or Google Ads integration — keep GA4 for those.
Will it slow my site down?
It's under 4 KB compressed, loads deferred, does its work in idle time and uses passive listeners. The one visible effect: if you use headline variants, the text can swap shortly after the page loads.
Do I need a cookie banner for it?
Pulse sets no cookies and doesn't fingerprint. It does keep a random per-tab session ID in the browser's session storage, and some privacy rules cover any device storage — so ask your privacy adviser. Pulse respects Do-Not-Track and has a consent switch.
What counts as a "win" for headline testing?
A form submit counts fully. A click on a buy, checkout, book or sign-up button counts most of the way, and deep engagement (more clicks, deep scrolling) counts a little. It's a sensible stand-in for sales, not your actual revenue — check winners against your real numbers.
How does it decide which version to show?
It uses a multi-armed bandit. Versions that score better get shown more often, while weaker ones still get occasional tries in case they improve. You don't wait for a fixed sample before traffic shifts.
How thorough is the SEO sentinel?
Eight on-page checks on every page someone visits: title, duplicate title, meta description, canonical, a single H1, image alt text, valid structured data and a social image. It doesn't crawl your site, test links or look at backlinks — use a crawler like Ahrefs or Semrush for that.
Are these the same speed numbers Google uses?
No. They're Pulse's own measurements from your real visitors' browsers, and its interaction score is a simplified stand-in. Google's ranking data comes from the Chrome UX Report — use Pulse for fast feedback and Search Console for the official figures.
Can it break my site?
Every part of the script is wrapped so an error inside Pulse can't take your page down. It will change the text of elements you've marked for variants — that's the point.
What data does it send?
Page paths (no query strings), the referring site's name, a coarse screen-size bucket and the events above. Never names, emails or form contents.
