Our lab run

3.1s

a single controlled load

Real visitors experience the field number because it reflects their real devices and networks; our lab run is one controlled load. When they differ, the field number is the one search and answer engines weigh — that is the reconciliation most scanners leave dangling.

This site doesn't yet have enough real-user traffic for field data — normal for many sites, and we won't invent a trend we can't measure.

What we found

Most people abandon a page that's slow to load on their phone — a slow site quietly loses visitors before they ever see what you offer, and search and AI systems factor load speed into how they rank and represent you.

How we know: derived from our page-speed measurement run

Nothing to act on here from what we could see — keep it that way.

How we know: derived from our audit run

What this means. Load speed is a documented ranking factor and the single biggest driver of whether a visitor stays. Real-user field data is what search and answer engines actually weigh — a snapshot can't show it.

How we know: read directly from your homepage

When search and AI systems can't cleanly crawl your page, they index and represent you worse — or skip parts of you entirely.

How we know: read directly from your homepage

If your page isn't clearly structured, search and AI systems understand it less well, so you show up for fewer of the things you actually do.

It bears on how reliably search and AI systems can crawl and index your site; the full investigation reads it directly.

How we know: read directly from your homepage

What this means. This is how a search result and an AI answer engine actually see your page — the title, the summary, the structure they read before anything else. Get these wrong and they represent you for fewer of the things you actually do.

Nothing to act on here from what we could see — keep it that way.

How we know: read from your DNS, certificate and response headers

Weak email and security signals let others spoof your address and make inboxes and browsers trust you less — which can cost you delivered email and customer confidence.

How we know: read from your DNS, certificate and response headers

What this means. DNS, mail authentication, TLS and security headers decide whether inboxes and browsers trust you — a blind spot for every scanner that only reads the page, and mostly readable even when your site refuses one.

Your addresses funnel to one clean, secure home

What we found

Nothing flagged here in what we could examine — a genuinely good sign, not a gap.

What this means. If your registration lapses, your site and email go dark overnight; and how your addresses redirect decides whether search sees one clean site or several competing for the same credit.

Nothing to act on here from what we could see — keep it that way.

How we know: checked against public safety lists

What this means. A site flagged as unsafe is hidden behind a browser warning and pushed out of results — the fastest way to become invisible and lose trust at once. A clean read is a narrow, honest trust signal, not a full security audit.

What we found

Nothing flagged here in what we could examine — a genuinely good sign, not a gap.

What this means. The wider web's endorsement is one of the strongest ranking factors, and the profiles you link to are how answer engines corroborate that you are who you say you are. The full link picture is the codex's.

How we know: read from your robots.txt and how your page renders

What this means. Most sites are built for search but not for the answer engines your customers increasingly ask instead of searching. This is a qualitative read of what those engines can reach and represent — never a fabricated score.

We examined https://www.mozilla.org/ (after following your site's redirects). We examined 1 page — your homepage — and read its content. We read robots.txt (present). No readable XML sitemap was found. This scan does not execute JavaScript and does not crawl beyond the homepage; a full investigation examines every page.

The full investigation

What the full Rank Codex investigation covers

Same data. Different instrument. Provable result.

This free scan read a single page. The Rank Codex investigates your whole site — the same honesty machinery you've seen here, turned up to a complete, defensible picture. This is the film to this trailer.

Four scored pillars

Rank, Visibility, Signal and Authority — one instrument for how findable, how answer-ready, how conversion-ready and how vouched-for your whole site is. Every score can be re-derived and verified: we show our work, never a black box.

Nine rank axes + seven AI-visibility phases

Each one measured reproducibly across your whole site, not a single page — the same honest machinery you've seen here, at full depth.

The penalty lane

Eight gates and thirteen risk patterns that quietly hold a site down — checked, and explained in plain English, so nothing is silently costing you.

Off-page investigation

The toxic links worth disavowing and the real, named opportunities to reclaim — the honest picture, never a padded count of spam dressed up as assets.

Live buyer-prompt testing

What an answer engine actually says when your customer asks — measured against real prompts, not guessed.

The master action plan

Every fix ranked, each with an owner, an effort and a 90-day sequence — so you know exactly what to do first, and why.

Ascent — the verification engine

When the work is done we re-measure and prove it worked: fixed, with evidence. That is the part no one else offers.
