Sembly AI — what a crawler receives from sembly.ai
Website measurement, not a product review. This page records what machine clients received from sembly.ai. It does not evaluate Sembly AI software, features, pricing or support.
Answer engines can technically reach this site, but get little they can use.
AI visibility 72/100, measured 2026-09-18 03:13 UTC from outside its network, as twelve named crawler identities plus an unnamed client and two mobile-browser controls. An engine can technically reach this site and would struggle to get anything quotable out of it.
Held at C A medium-severity finding sets the letter.

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
3 findings on this site, 1 of them scored serious. The top one is below in full, free. Which the other 2 are, what we saw, and the bytes behind each one are what a licence buys — or we implement the whole list for you.

What we saw
www.sembly.ai answers 200 and stays there: 61,563 bytes against 61,563 on the apex. Every page exists at two addresses.
Why it matters
Both www and the bare domain answer 200 with the same pages, so every URL on this site exists at two addresses and a crawler fetches the whole site twice. A canonical tag does not prevent this: it is read after the response arrives, so the second fetch has already been spent. Nothing looks broken from a browser, which is why this survives for years. The fix is a 301 from one host to the other so there is one address per page.
How to fix it
Pick one host (apex or www) and redirect the other to it with a 301 so there is one copy of every page.
Setting: a setting on the server, CDN, DNS or a plugin — no code and no writing

Get this fixed — $749The main product
We fix the 3 findings on sembly.ai. $749, 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 llms.txt. 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 61,519 decompressed bytes the homepage delivers, 9.3% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 9.3% · 5,695 B
- Markup & attributes 59.2% · 36,436 B
- Inline CSS 2% · 1,258 B
- Inline JavaScript 9.5% · 5,848 B
- Inline SVG 19.9% · 12,230 B
- HTML comments 0.1% · 52 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.
