Nomic AI — what a crawler receives from nomic.ai
Website measurement, not a product review. This page records what machine clients received from nomic.ai. It does not evaluate Nomic AI software, features, pricing or support.
Answer engines can reach and read this site. It needs more it can quote.
AI visibility 87/100, measured 2026-10-04 07:19 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?
The facts an assistant is asked for are declared and consistent.
The stage to fix first is read, because the three run in order.
What to fix
4 findings on this site, 3 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
15 named User-agent groups (20 agents) do not repeat 10 of the Disallow rules the `*` group carries. A crawler obeys only its own most-specific group and ignores `*` entirely, so those rules do not apply to any of the named agents (some declare their own, different rules). Worst group: `ahrefsbot, semrushbot, mj12bot, dotbot, blexbot, rogerbot` bypasses /api/, /_next/, /private/, /admin/, /assets/, /roadmap/, /internal/, /book-a-demo/thank-you, /thank-you, /gpt4all. This includes a SEARCH crawler (googlebot) — the bypassed paths are being crawled and can enter the index. /robots.txt
Why it matters
A crawler reads only the User-agent group that matches it best and ignores every other group, including `*`. Naming an agent and giving it only `Allow: /` therefore deletes all of your `*` Disallow rules for that agent. The file still parses and the agent still reaches your homepage, so this is invisible on inspection — but the paths you meant to keep out of search are open, and search engines will crawl and may index them.
How to fix it
Every User-agent group that names a crawler must repeat the Disallow rules you want applied. A named group with no rules means 'allow everything' for that crawler.
Setting: a setting on the server, CDN, DNS or a plugin — no code and no writing
On Next.js (detected)
- App Router: add app/robots.ts that returns a MetadataRoute.Robots object (rules per userAgent, sitemap URL). Pages Router or static export: put robots.txt in public/.
- Ship one of the two, not both: the route handler and a public/robots.txt collide.

We implement the list on your site and re-measure, with a sealed before and after. One site, $749 once.
Get this fixed — $749The main product
We fix the 4 findings on nomic.ai. $749, once.
3 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 233,277 decompressed bytes the homepage delivers, 3.5% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 3.5% · 8,163 B
- Markup & attributes 39.9% · 93,078 B
- Structured data (JSON-LD) 2.1% · 4,928 B
- Inline JavaScript 44.9% · 104,664 B
- Inline SVG 9.3% · 21,641 B
- HTML comments 0.3% · 803 B
The individual blocks that weigh the most, so the fix is a search rather than a hunt:

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.
