Sitebulb — what a crawler receives from sitebulb.com
Answer engines can reach and read this site. It needs more it can quote.
AI visibility 84/100, measured 2026-09-03 05:17 UTC from outside its network, as fifteen named crawler identities and one unnamed client. An engine can reach and read this site. What is left is giving it something specific to say.

The three stages, in the order an engine hits a site
Each stage gates the next. An engine that cannot reach a page never reads it; one that cannot read it never quotes it. That is why reach is a ceiling and not just a weight.
Stage 1 · 40% of the score
Reach
Can a named answer-engine crawler get your pages at all?
Every named crawler was served the same page a browser gets.
Stage 2 · 30% of the score
Read
Once it has the bytes, can it find the words?
The content is buried in markup, or the files that guide a crawler are missing.
Stage 3 · 30% of the score
Quote
Is there a specific fact it can state and attribute?
An assistant would have to paraphrase your page instead of quoting a fact.
The stage to fix first is quote, because the three run in order.
What to fix, in order
Findings first: each one holds the grade down until it is gone. Then headroom: each one lifts the score by the points shown. Open a card for what we saw, why it matters and how to fix it.
Files, generated from this scan
Each file says at its top exactly what was changed or filled and what was left as a TODO. Publish, then re-scan: done is measured.
1No llms.txtNot present.Note
What we saw
Not present. /llms.txt
Why it matters
Not a defect. llms.txt is an emerging convention for telling AI systems what a site is and which pages matter.
How to fix it
Publish /llms.txt: a short Markdown file naming the business, what it does, and the pages worth reading, served as text/plain or text/markdown.

2HTTPS is served without a Strict-Transport-Security headerThe homepage answered over HTTPS (200) with no Strict-Transport-Security header.Note
What we saw
The homepage answered over HTTPS (200) with no Strict-Transport-Security header.
Why it matters
Strict-Transport-Security tells a browser that has visited once to use HTTPS for every later request without trying HTTP first. Without it, a typed or linked http:// address makes one plaintext request before the redirect. It does not change what crawlers receive or how the site ranks; it is a small, reversible hardening step, and it is listed at the lowest severity for that reason.
How to fix it
Send Strict-Transport-Security: max-age=15552000; includeSubDomains on HTTPS responses (Cloudflare: SSL/TLS, Edge Certificates, HSTS). Leave preload off unless you intend a change that takes months to undo.

Headroom +16 points if every row passes
Nothing here is broken. Each row is a measure that currently fails its optimal range, and what fixing it is worth to the score.

See the fix serviceThe chain a crawler follows
The chain breaks at llms.txt. Everything after that point is only reachable by a crawler guessing the conventional path.
A machine file that does not parse is worth less than one that is absent, because it looks present. Rows behind this.
Where the bytes go
Of the 94,136 decompressed bytes the homepage delivers, 8.2% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
