Eight mornings of the same Hilton search

Between 2 and 23 October 2026 we ran one hotel corporate code search eight times in a signed-in Chrome, from the same network, and recorded every domain in the top ten. This page is the raw record: the table, the two experiments, and what did not change.

4domains that were in the top ten on 2 October and were gone by 23 October
2domains that were absent on 2 October and inside the ten on 23 October
1domain that never moved from first place
7web results in the ten slots, in every one of the four word variants

How the captures were made

Every run used the same signed-in Chrome profile on the same machine, over the same residential connection, with the same query, the same interface language and the same result count. The results page was saved and parsed by a script rather than read by eye, so a domain that appears in two places or an answer block that pushes a result down is recorded as it rendered, not as it is remembered.

What this cannot tell you. Eight runs on one network is not a population sample. Personalisation, location and account history are held constant here, which makes the change over time readable but does not license a claim about what other people see. A position recorded on one date is that date’s rendering for this account, nothing more.

Line chart: position of each domain across eight dated captures of the same search, rank 1 at the top. Four lines end before the last date because those domains dropped out of the top ten.
Rank 1 at the top, 10 at the bottom. A gap means the domain was not in the top ten on that date. Domains present in fewer than six runs are drawn faint. Source: verifiedhotelcodes.com/serp-notes, CC BY 4.0.

What moved, and what did not

Changing one word: codes, code, code list, codes list

On 19 October, in one morning, the same query was run four times with only the final word changed. The head noun moved between plural and singular, and the word list was added and removed.

hoteldig.com ranks ninth and cannot be read

hoteldig.com appears in six of the eight runs, twice at seventh, and it is one of the listings behind the code tables on this site. It also cannot be read. Direct requests from our network have returned HTTP 403 on every attempt. Opening it in a signed-in browser gives the front page of a Chinese-language travel blog with no Hilton list on it.

That is worth stating plainly because it is easy to conflate two different things: a domain that appears in a ranking, and a domain that is a source. This one is reliably the former and, from where we sit, not verifiably the latter. Nothing from it enters the verified tables on this site.
