The selection page now carries both dates. ''alexa.com'' redirects to the unrelated Amazon Alexa voice assistant.)) Its ranking service and its category service died together.
  
   * **Why it still matters**: it appears in 12 of the 330 corpus papers that categorise websites, under eight different spellings, and papers published as late as 2024 still use it because their data collection predates the shutdown. If you are reading such a paper, the labels are from a dead service with a documented 0.53% coverage rate.   * **Why it still matters**: it appears in 12 of the 330 corpus papers that categorise websites, under eight different spellings, and papers published as late as 2024 still use it because their data collection predates the shutdown.

   * **The TLD.** Precise where it exists and absent where it matters — a ccTLD is strong evidence, but generic TLDs carry no country at all, and that is most of the head of any list.   * **The TLD.** Precise where it exists and absent where it matters — a ccTLD is strong evidence, but generic TLDs carry no country at all, and that is most of the head of any list.
-  * **CrUX country lists, via Tranco.** Tranco's list-generation API takes ''filterCRUX'', ''filterCRUXType'' (''global'' / ''country'' / ''region'' / ''subregion''), ''filterCRUXValue'' (e.g. a list of country codes) and ''filterCRUXMonth'', so you can generate a country-restricted list reproducibly, with a permalink, from a free account.((https://tranco-list.eu/api_documentation — fetched 2026-08-07.

This is the cleanest free source and it is under-used. **But it ranks by page loads from Chrome users in a country, which is popularity, not audience** — and the overlap is severe: the union of five country top-10k lists (China, Germany, Italy, Korea, Turkey) is only 18,718 domains rather than 50,000, with 4,017 domains common to all five, and a preliminary labelling built from these lists is incompatible with the site's own TLD in at least 25% of cases for every label {[bozzolan2026_llmweb]}.+  * **CrUX country lists, via Tranco.** Tranco's list-generation API takes ''filterCRUX'', ''filterCRUXType'' (''global'' / ''country'' / ''region'' / ''subregion''), ''filterCRUXValue'' (e.g. a list of country codes) and ''filterCRUXMonth'', so you can generate a country-restricted list reproducibly, with a permalink, from a free account.((https://tranco-list.eu/api_documentation — fetched 2026-08-07.

   * **Site language.** A good proxy, and cheap, but it splits badly on English, Spanish, Arabic and Portuguese, which is a large share of the web.   * **Site language.** A good proxy, and cheap, but it splits badly on English, Spanish, Arabic and Portuguese, which is a large share of the web.
