vantage point
The network position a measurement is taken from. A datacenter vantage sees what a datacenter client is served, which can differ from what a residential browser or an operator's own crawler receives.
What vantage point does not show
A finding that depends on the vantage is stated with it; a second vantage, such as a browser extension, is how the dependence is measured rather than assumed.
How CrawlCheck measures vantage point
One finding code measures it. Its share of all scans is computed from the live corpus when this page is served, not typed into it.
| Finding code | Share of scans | Guide |
|---|---|---|
ORIGIN_REFUSED_SCANNER | 0.3% | dataset |
Every code, its rule and its current rate: the dataset page. Scan a site to see which apply to it.
Where vantage point comes up on this site
- Free AI visibility checkers: what the free tier actually measuresA single scan is one reading from one vantage point on one day: a deterministic block reproduces perfectly, so running it twice from the same machine is not corroboration.
- Google's goto redirect is real. The referrer still can't show it.How much of the rollout people report depends on their vantage point: Our reading (inference): the results fit a rollout gated by signals such as sign-in state and IP type.
- 33 AI visibility tools measured: a third publish llms.txt, none an entity mapA vendor whose edge challenges datacentre traffic is listed as refused CrawlCheck — not graded , with no number, because a number would be our vantage point dressed as their defect.
- Firewall or website? When an AI visibility tool grades your WAFIt was not: a deterministic block reproduces perfectly, so two identical readings from one vantage point are one reading.
- 25,983 MCP endpoints from the registry: what they answer, and the eleven whose tools talk to the modelHow this was measured, and what it does not show One vantage point, one evening.
