Google AI Overviews appeared on 57 of 65 searches (87.7%, CI 77.5–93.6%). The other 8 searches showed no overview. Within the 57 overviews, Laura Wasser was named in 11 (19.3%), Robert Stephan Cohen was named in 9 (15.8%), Aronson Mayefsky & Sloan was named in 7 (12.3%), Wasser Cooperman & Mandles was named in 6 (10.5%). youtube.com was the most-cited source, with 10 citations and an appearance in 9 of 57 overviews.

Citation share by source type

Share of all citations by the type of site cited. Source types were reclassified on October 29, 2026. 'Company / brand sites' now covers only the official sites of companies, brands and schools; publishers, directories, trade bodies and other sites have their own types, and sites that could not be placed are 'Other / unclassified'.

How can firms and lawyers improve their AI visibility?

These steps follow from the measured results above. They describe what the engines cited in this study and are not a guarantee of results.

How this study was measured

24 questions × 3 runs each × 4 AI engines = 288 answers + 65 Google searches · 57 AI Overviews

24 questions, each asked 3 times on each engine, measured October 28, 2026. Market: United States, English. The destination site was not mentioned to any engine. Gemini answers were produced by gemini-3.6-flash; every Gemini answer in this report used that one model. All 72 Gemini answers had search sources. Entities count as named when they appear in the answer text; products and name variants roll up to the tracked name, and people are matched with middle names or initials, nicknames, possessives and suffixes. First-name variants (for example Jeffrey for Jeff, William for Bill) are matched, but only together with the tracked last name. Law firms are also counted by their common short name (for example Weil for Weil Gotshal, Akin for Akin Gump), matched case-sensitively as a whole word; short forms that could mean a tracked lawyer or a common name are not used.

Own-domain citations count a domain plus all its subdomains, with the same rule in every table.

Definitions

• Appearance rate: answers naming the entity ÷ answers returned, with Wilson 95% intervals.
• First mention: average order in which the entity first appears (1 = first).
• Own-domain citation: grounded answers citing the entity's domains ÷ grounded answers.
• Citation share: citations to the entity's domains ÷ all citations.

Limits

• Measured on one day, October 28, 2026. Each engine answered 24 questions 3 times. Answers came from each engine's API (model IDs above); the consumer apps can answer differently.
• Only 11 tracked firms and lawyers were scored. Untracked names that appeared often were not scored, including Blank Rome LLP (55), Withers LLP (30), Fox Rothschild LLP (30), Mandelbaum Barrett PC (24), Gladstone, Weissman, Hirschberg & Schneider, P.A. (22).
• AI Overview figures are based on only 57 overviews, so estimates for individual firms and lawyers are less precise than the four-engine figures.
• 7 Google searches could not be fetched by DataForSEO after three tries. They are excluded from the AI Overview figures, so the trigger rate uses 65 searches.
• 3 Claude answers had no search sources after retries. They count for appearance but contribute no citations.
• Reports describe what the engines said, attributed to the engines. They make no judgement about the people or organizations named and are not legal or financial advice.
• Laura Wasser and her firm, Wasser Cooperman & Mandles, are tracked as separate names. Most answers that name one also name the other.
• Intervals treat each answer as independent, so they understate uncertainty for the 24 repeated questions.
