HeyGen — what a crawler receives from heygen.com
Website measurement, not a product review. This page records what machine clients received from heygen.com. It does not evaluate HeyGen software, features, pricing or support.
Answer engines can technically reach this site, but get little they can use.
AI visibility 74/100, measured 2026-10-10 21:17 UTC from outside its network, as each named AI and search crawler and as a browser. 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?
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?
An assistant would have to paraphrase your page instead of quoting a fact.

What to fix
5 findings on this site, 2 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
23 named User-agent groups (23 agents) do not repeat 2 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. Worst group: `yeti` bypasses /ebook/register, /app2/tr. This includes a SEARCH crawler (applebot) — 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.
In Cloudflare (this site is behind it)
- If Cloudflare's managed robots.txt is on (Security → Bots, or AI Crawl Control → robots.txt), Cloudflare adds its own lines above yours. Turn it off, or keep it knowing those lines are there.
- Robots.txt is cached at the edge: purge it (Caching → Configuration → Custom purge → the robots.txt URL) after you change it.

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 5 findings on heygen.com. $749, once.
2 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 443,803 decompressed bytes the homepage delivers, 3.1% is text a reader or a model can actually use. Most of what a crawler downloads here is not words.
- Readable text 3.1% · 13,715 B
- Markup & attributes 43.8% · 194,243 B
- Structured data (JSON-LD) 1% · 4,395 B
- Inline JavaScript 48.6% · 215,496 B
- Inline SVG 3.6% · 15,817 B
- HTML comments 0% · 137 B
