Sitebulb — what a crawler receives from sitebulb.com

Website measurement, not a product review. This page records what machine clients received from sitebulb.com. It does not evaluate Sitebulb software, features, pricing or support.

AI visibility 83/100, measured 2026-10-18 17:04 UTC from outside its network, as each named AI and search crawler and as a browser. 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, and one that cannot read it never quotes it.

91

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.

79

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.

77

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

3 findings on this site. Every one is named below; the top one is shown in full, free. What we saw, why each matters, how to fix it and the bytes behind it are what a licence buys — or we implement the whole list for you.

3 Note

1No llms.txtNot present: /llms.txt answered HTTP 404.NoteContent

What we saw

Not present: /llms.txt answered HTTP 404. /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.

Content: words, markup or images on a page — no deploy

Fix it with a coding agent

Paste into Claude Code, Cursor or Codex, opened on the code that serves this site.

You are working in the codebase (or server/CDN configuration) that serves sitebulb.com. A crawler audit found the problem below. Fix it at the source, keep the change as small as possible, and do not change anything a visitor sees unless the fix requires it.

Finding: No llms.txt (NO_LLMS_TXT, note severity)
Page: https://sitebulb.com/llms.txt
What was measured: Not present: /llms.txt answered HTTP 404.
Why it matters: Not a defect. llms.txt is an emerging convention for telling AI systems what a site is and which pages matter.

Full report (markdown): https://crawlcheck.io/r/qqb82vez66.md

When you are done:
1. Tell me which files or settings you changed and why.
2. If the fix is a server, CDN or cache setting you cannot change from the code, say exactly where it is set.
3. After deploying, re-scan at https://crawlcheck.io/?url=sitebulb.com . The fix counts when NO_LLMS_TXT is gone from the new report.

The chain a crawler follows

The chain breaks at llms.txt. Everything after that point is only reachable by a crawler guessing the conventional path.

✓robots.txtEvery crawler reads this first
✓sitemapNamed in robots.txt and resolves
✗llms.txtPoints onward, links stay on this host
✗entity graphParses as JSON and points home

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 96,793 decompressed bytes the homepage delivers, 8% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.

  • Readable text 8% · 7,725 B
  • Markup & attributes 73.4% · 71,026 B
  • Structured data (JSON-LD) 0.7% · 696 B
  • Inline CSS 5.7% · 5,514 B
  • Inline JavaScript 5.1% · 4,907 B
  • Inline SVG 7.2% · 6,925 B

The individual blocks that weigh the most, so the fix is a search rather than a hunt:

  • Inline CSS · 2,920 B (3%) — unnamedopens .webinar-banner { --green: #13ce66; --blue: #1fb6ff; text-align: cente
  • Inline CSS · 2,355 B (2.4%) — embedded web fontsopens @font-face { font-family: filson-soft; src: url('/fonts/subsets/filson
