These names were not in the business-or-not labeling pass dated 2026-10-07. They are shown as written, in answers where at least two named them, and have not been classified, so one may be a place, a term or a tool rather than a business. They are not counted in the table above.

Namebeam pages in Perplexity sources for this question: 0 of 69 answers (this page: 0 of 69). Namebeam pages in Google top results: 0 of 43 searches. Counted from the same fields as everything above. Zeros stay printed until they move.
This page is itself part of the test. On most days the same question is asked again, and the count above is updated from the record. Whether this page is ever cited is reported with its denominator, up or down.
Before the daily record began, a hand capture dated 2026-07-31 was logged for this question. It is kept here unchanged and is the earliest dated entry. Each block names the engine and account type used. Consumer apps and the API can answer differently.
Every answer on this page is one JSON file in the public record. The index for this page lists each row with its file name and SHA-256: namebeam.ai/data/e1/dallas-personal-injury.json. The files live in the repository namebeam-visibility-index, corpus/e1. 360 rows, 2026-08-09 to 2026-10-19.
How this was run. The prompt is the exact text above, sent unchanged once per day to each door, 2026-08-09 to 2026-10-19. Each row of the record keeps the date, the door, the run status and the answer text exactly as returned. Rows that failed are counted as failed in the table above and are not dropped. Business names are read from the answer text: bold names and names listed by the engine are collected, each must appear in the answer verbatim, and a language-model pass labels each as a business, an organization that is not a provider choice, or not a name. A name is classified only if it appears in at least two answers to this prompt, so a business named once is not in the table. Written variants of one name are merged under one label, and the data file lists every written form under each label. The label pass can miss or wrongly merge a name, so the raw files below are the record and this table is a reading of it. Counts are answers naming a business out of answers that returned text, per door and in total. The table is sorted by count, which is not a ranking of quality and not an endorsement of any business. API answers can differ from the logged-in consumer apps; the run channel is recorded on every row. Perplexity returned a median of 20 sources per answer. The question and the engines are the same every day; the engines themselves change over time. Namebeam is an educational and marketing service and does not guarantee rankings, traffic, or revenue.
