Every check is one tile.

Paste a URL, read the table, fix what’s first. The same tile tells you what a check is before you run it and what it found after.

Sample reading, not a real site: tile 5, HSTS, came back Warn.
  1. Number and group

    Its place on the chart, read left to right. The tint, the bar pattern and the group shape all say Security here, so colour is never the only clue.

  2. Symbol

    The two-letter code. The same symbol marks this check in the report and in the check reference.

  3. Name

    The check in full. Hover or focus a tile for its card: what it reads, why it matters and how to fix it.

  4. Result

    After a check the tile reads pass, warn, fail or info with the value found. Warnings and failures go to the fix-first list, each with the one change that clears it.

Seven graded groups. Thirty‑six checks.

Grouped the way a crawler meets a page: the response, the head, the structure, the headers, the domain. Technology fingerprints are reported alongside and never graded.

  1. Essential meta

    Title, meta description, viewport, charset and language: the basics every search snippet is built from.

  2. Crawlability

    Whether robots.txt and an XML sitemap are where crawlers look for them.

  3. Performance

    The response itself: HTTP status, page weight, redirect hops and content type.

  4. Technical SEO

    Canonical, robots meta, H1, structured data, internal and external links, word count.

  5. Security

    HSTS, CSP, framing and sniffing protection, referrer policy and cookie flags.

  6. Social sharing

    Open Graph and Twitter Card tags that decide how a shared link looks.

  7. DNS & email

    A, AAAA, NS and MX records, plus SPF and DMARC for the domain’s email.

  8. Technology

    Fingerprints of the platforms, frameworks and hosts a page runs on. Reported, never graded.

Read your site like the chart.

It takes a few seconds and needs no account. The report comes back as this same table, graded.
