Same-host rule: counting only what the host being read serves
The same-host rule counts a language alternate only when it is served from the host being read. Alternates pointing at subdomains, national domains or separate brands are recorded and not counted, for every vendor alike. As of 2026-09-22.
| Rule | What it measures | Where it breaks |
|---|---|---|
| Same host only | How much of its own site a vendor translated | Understates companies organised by subdomain |
| Any host in the cluster | How many properties a company runs | Rewards owning domains over translating pages |
| Whatever seems fair per vendor | Nothing comparable | Cannot be reproduced by a reader |
Inclusion rule. The counting rules available for this column. The first is applied here to every vendor without exception. Order. The rule in use first.
1The narrow rule is chosen for reproducibility
Both of the first two rules are defensible. Counting other hosts is arguably fairer to a company with regional offices; counting only one host is arguably fairer to a company that translated its own pages.
What is not defensible is the third option. A rule chosen per vendor produces a column nobody can re-derive, and the choices would land on whichever reading flattered the vendor being written about that day.
2It costs two vendors here almost everything
Two vendors declare twelve and sixteen alternates and serve nearly all of them from language subdomains. Both are counted at one. Those subdomains are real pages and real work.
So the raw declaration is printed on both of their pages beside the counted figure. A reader who prefers the broader rule has the numbers to apply it and can disagree with the step rather than with the table.
3It also hides one market twice
Two further vendors declare a Chinese alternate that resolves to a separate domain, and the rule discards both. Companies selling into mainland China commonly run a separate domain for it.
That is a real limitation, recorded on both vendor pages. A rule visible only where it helps somebody would not be a rule, and a rule with no stated cost would not be honest.
A definition, not a measurement: no vendor figure appears here that is not also in the register. The rule and its two discards are set out in full on the how counted page.
