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.
AI assistants like ChatGPT can read your site, but find little to quote about your product.
AI visibility 82/100, measured 2026-10-30 02:33 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?
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, the lowest of the three.
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.

What we saw
http://fiddler.ai/ takes 2 redirects to reach the page: 301 permanent (http→https) → 301 permanent (apex→www) → https://www.fiddler.ai/ (200). Point the first redirect straight at the final address.
Why it matters
Reaching the homepage takes more than one redirect, for example http to https and then the domain to www. Each hop is another request and round trip before a crawler or visitor gets the page, temporary hops (302, 307) tell search engines to keep the old address, and Google stops following after ten.
How to fix it
Send every old address straight to the final one in a single permanent (301 or 308) redirect: in the host, CDN or plugin rules, redirect http://domain and http://www straight to the final https address instead of chaining scheme, host and path fixes.
Setting: a setting on the server, CDN, DNS or a plugin — no code and no writing
Fix it with a coding agent

You are working in the codebase (or server/CDN configuration) that serves fiddler.ai. 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: The homepage is reached through a chain of redirects (REDIRECT_CHAIN, note severity) Page: https://fiddler.ai/ What was measured: http://fiddler.ai/ takes 2 redirects to reach the page: 301 permanent (http→https) → 301 permanent (apex→www) → https://www.fiddler.ai/ (200). Point the first redirect straight at the final address. Why it matters: Reaching the homepage takes more than one redirect, for example http to https and then the domain to www. Each hop is another request and round trip before a crawler or visitor gets the page, temporary hops (302, 307) tell search engines to keep the old address, and Google stops following after ten. How to fix it: Send every old address straight to the final one in a single permanent (301 or 308) redirect: in the host, CDN or plugin rules, redirect http://domain and http://www straight to the final https address instead of chaining scheme, host and path fixes. Detected platform: Webflow. Make the change where this platform controls it. Rule and examples: https://crawlcheck.io/rules/REDIRECT_CHAIN Full report (markdown): https://crawlcheck.io/r/kdj2lbim4f.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=fiddler.ai . The fix counts when REDIRECT_CHAIN is gone from the new report.

What we saw, why it matters, how to fix it, and the evidence bytes for every finding — on this report and every re-scan. From $29 a month.
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 3 findings on fiddler.ai. $100, once.
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 166,038 decompressed bytes the homepage delivers, 6.2% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 6.2% · 10,300 B
- Markup & attributes 56.5% · 93,802 B
- Structured data (JSON-LD) 2.5% · 4,156 B
- Inline CSS 2.6% · 4,385 B
- Inline JavaScript 14.2% · 23,609 B
- Inline SVG 17.6% · 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:
