// TOOL 03 — ON-PAGE FORENSICS: ONLINE
Website Health Scan
Paste a URL. In seconds you get a prioritized list of exactly what's holding the page back in search — the deindexing traps, the missing tags, the thin content — each with a plain explanation and the fix. The same triage we run before every engagement.
What the scan grades
- C-01
Indexability traps
The highest-severity checks: noindex meta tags, X-Robots-Tag headers, and robots.txt blocks that quietly remove a page from search entirely. One leftover line can deindex a whole section.
- C-02
Core on-page tags
Title tag and meta description presence and length, exactly-one H1, heading structure, canonical, and language declaration — the fundamentals search engines read first.
- C-03
Mobile, images & social
Viewport meta for mobile-first indexing, image alt-text coverage, and Open Graph tags that control how your links look when shared.
- C-04
Content & structured data
Visible content depth, HTML page weight, and JSON-LD validity — flagging thin pages and broken schema that forfeit rich results.

What does the Website Health Scan check?
It fetches the page's raw HTML and its robots.txt, then grades the on-page fundamentals that actually move rankings: title tag presence and length, meta description, H1 and heading structure, indexability (noindex meta, X-Robots-Tag header, robots.txt blocks), canonical tag, mobile viewport, image alt coverage, Open Graph tags, structured data validity, content depth, and HTML page weight. Each finding comes with a plain-English explanation and a fix.
Is this the same as Lighthouse or PageSpeed?
No. PageSpeed and Lighthouse focus on performance metrics (Core Web Vitals). This scan focuses on the SEO and crawlability issues that keep a page from ranking or being cited at all — the things that don't show up in a speed score but quietly cost you traffic. They're complementary.
Why does indexability matter so much?
A page with a stray noindex tag or a robots.txt block is invisible to search no matter how good the content is. These are among the most common and most damaging issues we find — a single line left over from a staging site can deindex an entire section. The scan flags them first.
Does a perfect score mean I'll rank #1?
No. This scan covers the technical and on-page foundation — necessary, not sufficient. Ranking also depends on content quality, authority, backlinks, and competition. A clean scan means nothing is actively holding the page back, so the harder work of authority and relevance can pay off.
