Optyino.ai / Wallabee
Independent contextual study: PR URL presence
Optyino.ai / Wallabee is a different large-scale study design. It separately reports answer counts and deduplicated citation URLs, so the page treats it as context rather than a pooled extension of the Netsujo study.

Limitations
- The Netsujo study is one fixed Japanese B2B procurement sample, not a market-wide share estimate.
- The Optyino.ai / Wallabee figures use different denominators for answers and deduplicated citation URLs, so they cannot be pooled with Netsujo citation counts.
- The page republishes publisher-reported facts plus bounded interpretation; it does not prove causal business impact or future citation probability.
