QuillBot — what a crawler receives from quillbot.com
Website measurement, not a product review. This page records what machine clients received from quillbot.com. It does not evaluate QuillBot software, features, pricing or support.
AI assistants like ChatGPT can read your site, but find little to quote about your product.
AI visibility 76/100, measured 2026-11-01 01:49 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.
Stage 1 · 40% of the score
Reach
Can a named answer-engine crawler get your pages at all?
At least one answer engine was refused, challenged or served less than a browser.
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?
The facts an assistant is asked for are declared and consistent.
The stage to fix first is read, the lowest of the three.
What to fix
5 findings on this site, 1 of them scored serious. 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.

What we saw
1.1% of 833,326 decompressed bytes is visible text, and the largest single block is inline javascript at 355,730 bytes (a framework state payload)
Why it matters
A crawler pays for every byte it fetches and can only quote the text. Under 5% readable content means an answer engine downloads the whole page and comes away with almost nothing it can use — the difference between being quotable and being skipped. The content-ratio row above passes at 20%, so without this a page at 2% and a page at 19% were scored identically.
How to fix it
Move inline CSS and JavaScript into external files, drop unused page-builder styling, and make sure the words a visitor reads are in the HTML itself.
Developer: a template, theme or application change — a developer touches it

You are working in the codebase (or server/CDN configuration) that serves quillbot.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.

Rule and examples: https://crawlcheck.io/rules/PAGE_IS_MOSTLY_CODE Full report (markdown): https://crawlcheck.io/r/zlw8na76je.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=quillbot.com . The fix counts when PAGE_IS_MOSTLY_CODE is gone from the new report.

Unlock the findingsOr have them fixed
We implement the list on your site and re-measure, with a sealed before and after. One site, $100 once.
Get this fixed — $100The main product
We fix the 5 findings on quillbot.com. $100, once.
1 of them are scored serious. One site. You keep the grade for free — this is the part where the list stops being a list.
- Every finding implemented on the site itself: machine files, schema, NAP, the lot
- An entity map authored for your business, not a template with the name swapped
- Measured again afterwards — the before and the after, sealed, so it is evidenced rather than claimed
- Thirty days of monitoring included
- Work starts within two business days
What it covers · one payment, nothing recurring
The chain a crawler follows
The chain breaks at entity graph. 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 833,326 decompressed bytes the homepage delivers, 1.1% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 1.1% · 8,796 B
- Markup & attributes 14.7% · 122,582 B
- Structured data (JSON-LD) 0.2% · 1,461 B
- Inline CSS 19% · 158,114 B
- Inline JavaScript 48.7% · 405,431 B
- Inline SVG 16.4% · 136,942 B
The individual blocks that weigh the most, so the fix is a search rather than a hunt:
