Built for the audit → fix → re-audit loop
Most SEO checkers stop at the diagnosis. You get a score, a red list, and the job of working out what to actually change. This one is built to close the loop: every failing check carries the specific fix, and those fixes are assembled into prompts you can hand straight to an AI coding assistant.
Issues are separated by where the fix lives. Pre-production items are changes in your application code — meta tags, headings, content, structured data. Post-production items live in hosting, CDN or deploy config — HTTPS, compression, caching, security headers, TTFB. Mixing those two into one list is why SEO reports so often go unactioned; separating them means each prompt goes to whoever can actually apply it.
Fix, reload, re-audit. The score is the feedback signal, and the ranking tells you which fix buys the most improvement for the least work.
The six perspectives and their weights
- Meta Tags (20%) — title and description length, canonical and whether it self-references, URL quality, noindex, viewport, lang, charset, favicon, hreflang, structured data.
- Content Quality (20%) — a single H1, heading nesting, word count, image alt coverage, width/height for layout stability, lazy loading, modern image formats, internal and outbound links, broken links, text-to-HTML ratio.
- Technical / Delivery (20%) — HTTPS, status and redirect chain, compression, Cache-Control, CDN fingerprint, TTFB, HTML weight, robots.txt, XML sitemap, HSTS and security headers.
- Rendering & Indexability (20%) — how much content exists before JavaScript runs, whether robots.txt blocks crawling, noscript fallback, and edge cache delivery.
- Keywords & Readability (10%) — Flesch reading ease, generic anchor text, and the keywords and phrases the page actually emphasises.
- Social Sharing (10%) — og:title, og:description, og:image and twitter:card, with a preview of the share card.
Honest limits
- The page is fetched without executing JavaScript — the crawler's view. That is the point, not a shortcut: it is exactly why a client-rendered page scores low here.
- Core Web Vitals (LCP, INP, CLS) and paint timings need a real browser, so they are not scored rather than estimated. Use Lighthouse or PageSpeed Insights alongside this.
- Rendering detection is probabilistic and labelled with its confidence. Uncached SSG is genuinely indistinguishable from fast SSR from the outside.
- On-page factors only. Backlinks, domain authority and rankings are off-page and nothing on this page claims to measure them.
