# Rudra Website Analyzer

> Rudra Website Analyzer is a website audit tool. It crawls a website and audits each page for technical SEO, performance, accessibility, security, content and functional issues, then produces a website audit report with scores, issues ranked by severity and a suggested fix for each.

Key facts:

- Audits cover: technical SEO (titles, meta descriptions, headings, canonicals, robots directives, sitemaps, hreflang, structured data, Open Graph), performance (server response time, page weight, request count, render-blocking resources, compression, images without dimensions), accessibility (static WCAG checks, plus axe-core in full scans), security (HTTPS, TLS certificate and version, mixed content, security headers), content, functional errors (broken links, JavaScript errors) and infrastructure (compression, TLS, SPF/DMARC).
- A separate responsive layout audit renders pages on up to eight device profiles and flags overflowing or overlapping content.
- The site crawl flags common causes of poor Core Web Vitals; it does not measure field Core Web Vitals.
- Reports can be downloaded as PDF and CSV, and a crawl can be compared with an earlier crawl of the same site.
- Free single-page tools (website audit, SEO, speed, mobile, broken links, accessibility, security) run without an account, rate-limited per network. The API tester needs a free account.
- Single-page checks: the overall score is the average of the categories that produced a result; a category whose engine is unavailable is left out, not scored as zero. Speed is a single Lighthouse lab run (it can't measure INP); accessibility uses axe-core's automated rules, which find only part of the problems; the security check reads HTTPS, certificate and headers and is not a penetration test.
- Analyses (scans, crawls, layout tests, screenshots) are deleted automatically 24 hours after their last activity.
- The free plan requires sign-up and covers up to 2 websites with up to 10 pages per scan. Rescanning a website already on an account does not use a new website slot.
- The interface is available in 7 languages: en, fr, pt-BR, de, ar, ja, zh. Blog articles are in English.
