# How to read your Pulse scan report

> The Pulse report grades four pillars (uptime, performance, security, SEO), each with drill-downs. Grades are A–F using the same weights as the paid product.

## Quick answer

 Four pillar scores (uptime, performance, security, SEO) → weighted overall grade A–F. Click any pillar to see the exact checks that passed/failed.

## What each pillar covers

- Uptime : HTTP 2xx, response time, SSL validity

- Performance : TTFB, HTML size, compression, HTTP/2+

- Security : HSTS, CSP, X-Frame-Options, secure cookies, TLS version

- SEO : title, meta description, canonical, robots, structured data, hreflang

## Where to find it in Lemwatch

 **/pulse/<scan-id>** — shareable public URL for every scan.

## How to act on findings

- Fix any red (F) items first — they usually take minutes.

- Amber (C/D) items are best-practice gaps.

- Green (A/B) items are healthy — no action needed.

- To re-scan after a fix, run Pulse again — new scan, new ID.

## FAQ

### Why is my grade different from PageSpeed?

 Different methodology. Pulse is a fast lab check, not a Chrome-UX rollup.

### Are Pulse scores comparable to the paid product?

 Yes — same scoring weights, single-region only.
