pulsoraSite audit and Core Web Vitals
A weekly crawl of your site with a 0–100 health score and a fix for every issue, plus real-user Core Web Vitals from the Chrome UX Report.
The Audit view of the SEO tab crawls your site once a week, checks every page it finds and gives you a health score from 0 to 100. Below it, Core Web Vitals show how fast your pages are for real Chrome users.
How the crawl works
- Where it starts: your homepage, the URLs in your sitemap (from
robots.txt, or/sitemap.xml), and your 200 most visited paths in Pulsora from the last 30 days. Pageview data finds pages a sitemap misses. - What it follows: links on the same host, with or without
www. Images, PDFs, scripts and other files are skipped. - robots.txt: the crawler obeys the rules for
PulsoraBot, or for*when there is noPulsoraBotgroup. - Identity: it sends the user agent
Mozilla/5.0 (compatible; PulsoraBot/1.0; +https://pulsora.co/docs/seo/site-audit). - Load on your server: at most 4 requests at a time, each with a 10-second timeout. Redirects are recorded, not followed blindly.
- Pages per crawl: 100 on Starter and during the trial, 500 on Growth, and 2,000 on Business and higher plans.
Every site is audited once a week at its own hour, and new sites within an hour of being added. Owners and admins can Re-run audit once an hour.
To block the crawler, add this to robots.txt:
User-agent: PulsoraBot

Health score
Each crawled page is worth 5 points. Every error takes away 5 and every warning 1; notices take away nothing. The score is the share of points left, from 0 to 100. The trend shows your last 8 audits.
Core Web Vitals
Pulsora reads the Chrome UX Report, Google's public data from real Chrome users, once a week:
- For the whole site, on mobile and desktop, with up to 25 weeks of history.
- For your 10 most visited pages of the last 28 days.
| Metric | Good | Needs work | Poor |
|---|---|---|---|
| Largest Contentful Paint (LCP) | up to 2.5 s | up to 4 s | over 4 s |
| Interaction to Next Paint (INP) | up to 200 ms | up to 500 ms | over 500 ms |
| Cumulative Layout Shift (CLS) | up to 0.1 | up to 0.25 | over 0.25 |
Values are the 75th percentile over 28 days. Sites and pages with too few Chrome visitors have no data in the report, and Pulsora says so instead of guessing.
