GEO-paper vendor echoes — "Princeton GEO: 30–40% higher visibility" repeated by many SEO vendors all trace back to the same arXiv paper; repetition, not independent confirmation

Claim: Numerous SEO vendors repeat "Princeton GEO: 30–40% higher visibility from statistics / citations." All trace back to the same arXiv paper, so they are repetition, not independent confirmation.

Source: Cross-vendor observation, 2024–2026.

Confidence: Single-source (one primary, many echoes).

Why this matters for Candid: Editorial-discipline reminder. When the vendor chorus all sounds confident, check whether they're actually citing different studies. Here the answer is no — Aggarwal et al. is doing the work for every "GEO study shows" quote in the SEO press.
