Ora's cached score

Not scored by Ora. GET ora.ai/api/score/nielsen.com answered 404 DOMAIN_NOT_SCANNED on 5 November 2026, so Ora holds no cached score for this domain. This site asked for a cached score only and never requested a scan. A scan by the site's owner would add one.

Linking and the companion file

The home page of nielsen.com does not link the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. No llms-full.txt was found at the same root.

How it compares

At 42 KB the file is larger than 90 percent of the 2,529 plain-text llms.txt files in this edition, and its 178 links put it ahead of 89 percent of them on link count. The home page declares no generator. Size bucket: 10 to 50 KB. Tranco rank 2,230. Category: Top 10,000, no category.
