Fiddler AI — what a crawler receives from fiddler.ai
Website measurement, not a product review. This page records what machine clients received from fiddler.ai. It does not evaluate Fiddler AI software, features, pricing or support.
Answer engines can reach and read this site. It needs more it can quote.
AI visibility 80/100, measured 2026-10-06 18:19 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; 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.
Fix one thing: what it changes
| Fix | Clears | Score | Letter | Also needs |
|---|---|---|---|---|
| the homepage's code weight | 3 rows | 80 → 82 | B → B | — |
| llms.txt | 2 rows | 80 → 81 | B → B | — |
| XML sitemap | 1 row | 80 → 80 | B → B | — |
| entitymap.json | 1 row | 80 → 80 | B → B | — |
| the machine-file chain | 1 row | 80 → 80 | B → B | — |
Each line is the grade formula rerun with that one fix in place; computed, not measured. The rescan after the fix is the measurement.
llms.txt reader check
Nobody publishes whether anything reads llms.txt. One line settles it for this site: paste it into the file, and every fetch of that link is counted here - who, and whether Cloudflare verified them.

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.
Headroom +20 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.

Start watching fiddler.aiThe 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 163,397 decompressed bytes the homepage delivers, 6.3% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 6.3% · 10,296 B
- Markup & attributes 57.2% · 93,382 B
- Structured data (JSON-LD) 2.5% · 4,156 B
- Inline CSS 2.7% · 4,385 B
- Inline JavaScript 13.1% · 21,392 B
- Inline SVG 17.9% · 29,220 B
- HTML comments 0.3% · 566 B
The individual blocks that weigh the most, so the fix is a search rather than a hunt:

Dispute or re-scan
If a reading here is wrong, it is our instrument that is wrong, and we want to know. Tell us what is wrong and the site is re-measured; the result is published as measured. Nothing about a listing, a payment or a request changes a number.
