Benchmark Summary
Barley Snyder led the Law Firm index in August 2026 with a valid recommendation coverage of 17.2%, unchanged from 17.2% in July 2026. The gap to the next closest firm, shared by Eckert Seamans and McNees Wallace & Nurick, stood at 6.9 percentage points in August 2026, widening from 0.0 points in July 2026.
This was a quiet month for the category. No tracked firm recorded a significant rise or decline, and every movement stayed within normal month-to-month variation. No firm recorded a coverage increase this month; within that flat pattern, McNees Wallace & Nurick's valid recommendation coverage moved the most, down 6.9 points from 17.2% to 10.3%, while Obermayer and Stevens & Lee each declined 3.5 points, from 3.5% to 0.0%.
Across the full series, Barley Snyder and Eckert Seamans each held steady at 17.2% and 10.3% respectively from July 2026 to August 2026, while Saxton & Stump held at 3.5% and McCormick Law Firm remained at 0.0% in both months.
The benchmark began with 257 prompt-surface observations in July 2026 and 271 in August 2026, producing 29 qualified observations in each month after qualification.

How to Read the Standings
- Presence rate: share of qualified observations where the brand is mentioned in any form.
- Valid recommendation coverage: share of qualified observations where the brand receives a valid recommendation.
- Top-three rate: share of qualified observations where the brand appears in the first three recommendation positions.
- Rank-one rate: share of qualified observations where the brand is recommended first.
- Net sentiment: positive mentions minus negative mentions, divided by total mentions.

Recommendation Coverage Movement
Brand | Jul 2026 | Aug 2026 | Movement since baseline |
|---|---|---|---|
Barley Snyder | 17.2% | 17.2% | No change |
Eckert Seamans | 10.3% | 10.3% | No change |
McCormick Law Firm | 0.0% | 0.0% | No change |
McNees Wallace & Nurick | 17.2% | 10.3% | Down 6.9 points |
Obermayer | 3.5% | 0.0% | Down 3.5 points |
Saxton & Stump | 3.5% | 3.5% | No change |
Stevens & Lee | 3.5% | 0.0% | Down 3.5 points |
The month-over-month moves matched the baseline-to-current moves for every firm, since the series spans only two months. McNees Wallace & Nurick recorded the largest single-month drop, falling 6.9 points from July 2026 to August 2026, while Obermayer and Stevens & Lee each declined 3.5 points. No firm rose from July 2026 to August 2026.
All seven firms were classified as stable; none moved beyond normal month-to-month variation, so no significant riser or decliner subsections apply.
Category Leader: Barley Snyder
Barley Snyder led valid recommendation coverage at 17.2% in August 2026, unchanged from 17.2% in July 2026 and representing 5 valid recommendations out of 29 qualified observations in each month.

Company Focus: McCormick Law Firm
McCormick Law Firm held a 3.5% presence rate in both July 2026 and August 2026, meaning it was mentioned in roughly 1 of the 29 qualified observations each month. That presence did not translate into any valid recommendation, top-three placement, or rank-one placement in either month, and valid recommendation coverage held at 0.0% across the full two-month series. Net sentiment stood at 0.0 in both months.
Barley Snyder records 17.2% valid recommendation coverage in August 2026, while McCormick Law Firm stands at 0.0%. The more important issue is what that gap means for McCormick Law Firm's recommendation position: McCormick Law Firm's existing AI presence is not converting into a recommendation of any kind, let alone a top-three or first-choice placement, in a market where the leader is doing so more than 1 in 6 times. This is a clear gap on the metric that most directly reflects commercial outcome, and it has persisted unchanged across both measured months rather than showing early movement in either direction.
Highest-priority diagnostic: Why is McCormick Law Firm's existing AI presence failing to convert into any valid recommendation, and what would need to change in how the firm is described or cited on qualifying surfaces to close the gap to Barley Snyder's 17.2% coverage?
Recommendation Placement Snapshot
Valid recommendation coverage does not show how prominently a firm is recommended. In August 2026, Barley Snyder held the highest top-three rate at 10.3% (3 observations), and McNees Wallace & Nurick matched that top-three rate while leading the rank-one rate at 10.3% (3 observations). Eckert Seamans held a 3.5% top-three rate with no rank-one placements in August 2026, down from a 6.9% top-three rate and 3.5% rank-one rate in July 2026.

Eckert Seamans | 3.5% | 0.0% | 6.9% | 3.5% |
Similar coverage levels can still hide different first-position rates: Eckert Seamans and McNees Wallace & Nurick shared 10.3% valid recommendation coverage in August 2026, but McNees Wallace & Nurick reached the first position in 10.3% of observations while Eckert Seamans recorded no rank-one placements.

Evidence and Source Layer
This benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that a cited source caused a given recommendation.
Scope Boundaries
This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, or private/sponsored channels. A metric movement alone does not establish causality. The two-month series is too short to treat any movement as a trend.
