How AI Search Is Recommending Registered Agent Services: Monthly Trends

Executive Summary

Northwest Registered Agent remains the category's coverage leader in September 2026, holding valid recommendation coverage of 59.9% and a 9.1-point gap over ZenBusiness at 50.8%. This is a slightly narrower lead than in August 2026, when Northwest Registered Agent's 61.4% coverage put it 9.1 points ahead of ZenBusiness at 52.3%. The benchmark shows Northwest Registered Agent's position as stable despite a second straight month of modest decline, keeping it clearly ahead of the field.

The category's most consequential movement is visible across the baseline-to-current series. Since July 2026, seven of the ten tracked brands registered significant declines: LegalZoom is down 14.7 points from 57.0% to 42.3%, InCorp is down 9.5 points from 16.1% to 6.6%, Harbor Compliance is down 8.5 points from 22.2% to 13.7%, Rocket Lawyer is down 7.8 points from 16.1% to 8.3%, Bizee (Incfile) is down 7.4 points from 49.3% to 41.9%, ZenBusiness is down 6.4 points from 57.2% to 50.8%, and Registered Agents Inc is down 1.9 points from 2.3% to 0.4%. No significant risers emerged over the same window.

This month itself was comparatively quiet. No brand moved beyond normal month-to-month variation between August and September 2026, making September a consolidation month after the sharper contractions concentrated in August. The absence of significant single-month movement means the category's current shape is the product of accumulated declines across the summer rather than a fresh shock in September.

Each monthly run begins with 800 prompt-surface observations (456 unique questions in July 2026, 519 in August 2026, and 519 in September 2026) across the benchmark's defined AI/search surface universe. Of those, 800 mentioned a tracked brand or competitor in all three months; 757 were relevant and 43 were irrelevant in July 2026, 764 were relevant and 36 were irrelevant in August 2026, and 767 were relevant and 33 were irrelevant in September 2026. The public metrics use the 442 qualified observations in July 2026, 474 in August 2026, and 504 in September 2026 that survive both qualification stages.

Key Findings

Benchmark Context

The report separates the raw collection universe from the qualified analysis set. Brand-level recommendation percentages are calculated within the qualified benchmark set.

The qualified set grew steadily across the series, from 442 observations in July 2026 to 474 in August 2026 and 504 in September 2026. That expansion matters for interpreting the declines below: most brands lost coverage share even as the qualified denominator grew.

Benchmark-Level Metrics

The composition shift visible in August continued into September. Recommendation-shaped answer share fell to 29.4% in September 2026 from 38.0% in July 2026, and the valid recommendation shortlist share dropped to 60.3% from 67.4%. More qualified observations are yielding proportionally fewer recommendation-shaped answers, a compositional shift that coincides with the broad coverage declines documented across the category below.

AI Recommendation Trend

The category leader held position while the middle tier compressed through accumulated decline

Northwest Registered Agent retained the top position in September 2026 with 59.9% valid recommendation coverage, down 4.6 points from 64.5% in July 2026, a shift within its stable range. The competitive story is the compression behind it. In July 2026, ZenBusiness and LegalZoom were nearly tied for second at 57.2% and 57.0%, with Bizee (Incfile) at 49.3%. By September 2026, the second tier had narrowed into a cluster of ZenBusiness at 50.8%, Bizee (Incfile) at 41.9%, and LegalZoom at 42.3%, with LegalZoom and Bizee (Incfile) now effectively tied for third.

The September-to-September comparison table above masks an important distinction: LegalZoom's largest single-month decline happened in August 2026 (down 12.5 points), while its September movement was a smaller 2.2-point decline. The same pattern holds for InCorp (down 7.5 points in August, 2.0 points in September), Harbor Compliance (down 6.4 in August, 2.1 in September), and Rocket Lawyer (down 7.0 in August, 0.8 in September). The category's contraction was front-loaded into August, with September serving as a quieter continuation.

What Changed This Month

Northwest Registered Agent

Northwest Registered Agent's coverage eased 1.5 points from 61.4% in August 2026 to 59.9% in September 2026, and 4.6 points from 64.5% in July 2026. This movement stayed within its stable range. The brand remains the category leader with a 9.1-point gap over ZenBusiness.

The supporting signals point in opposite directions. Raw mention presence rose to 93.1% of qualified observations in September 2026, up 4.6 points from 88.5% in July 2026. But top-three recommendation rate eased to 51.0% from 56.8% over the same window, and rank-one rate held roughly steady at 24.2% versus 23.1%. Valid recommendation counts rose from 285 in July 2026 to 302 in September 2026 even as the coverage percentage edged down, reflecting the larger qualified denominator.

The distinction to notice is between presence and conversion. Northwest Registered Agent is surfaced more often than any other brand, appearing in 93.1% of qualified observations, yet its recommendation outcome share has drifted down from the July 2026 peak.

Highest-priority diagnostic: Which answer formats or prompt families are surfacing Northwest Registered Agent without converting it into a recommendation, and is that drift concentrated on specific AI surfaces?

Bizee (Incfile)

Bizee (Incfile) posted the largest month-over-month movement in September 2026, with coverage down 4.7 points from 46.6% in August 2026 to 41.9%. That single-month shift was within its normal range, but the cumulative decline of 7.4 points from 49.3% in July 2026 qualifies as significant. Valid recommendation counts fell from 218 in July 2026 to 211 in September 2026 while the qualified denominator grew.

The erosion is concentrated in outcomes rather than visibility. Raw mention presence fell from 65.6% to 60.1% over the series, a 5.5-point decline within its normal range. Top-three recommendation rate dropped from 32.6% to 29.0%. By contrast, rank-one rate improved from 2.7% to 3.8% over the same window, and net sentiment eased from 0.8 to 0.7.

Bizee (Incfile) is winning a slightly larger share of first-place recommendations even as its overall coverage contracts, suggesting the decline is in breadth of recommendation rather than in top-of-list prominence.

Highest-priority diagnostic: Which mid-tier queries stopped including Bizee (Incfile) in recommendation shortlists, and do the queries it still wins share a common attribute profile?

LegalZoom

LegalZoom's coverage fell 2.2 points from 44.5% in August 2026 to 42.3% in September 2026, a modest continuation of its 12.5-point August decline. The cumulative movement is the category's largest: down 14.7 points from 57.0% in July 2026, with valid recommendation counts falling from 252 to 213 over the series.

LegalZoom's raw mention presence remains high at 82.7% of qualified observations in September 2026, down from 85.3% in July 2026 but still the second-highest presence in the category. The decline is concentrated in outcomes: top-three rate eased from 17.6% to 16.7%, rank-one rate from 2.7% to 2.0%, and net sentiment dropped from 0.7 to 0.5.

The distinction between presence and recommendation is most visible for LegalZoom. It appears in roughly 8 of every 10 qualified observations but is recommended in fewer than half of them, a gap that has widened across the summer.

Highest-priority diagnostic: Which high-intent prompt families shifted away from recommending LegalZoom during the July-to-September window, and which competitor now captures those recommendations?

InCorp

InCorp's coverage declined 2.0 points from 8.6% in August 2026 to 6.6% in September 2026, and 9.5 points from 16.1% in July 2026. The cumulative decline is significant, with valid recommendation counts falling from 71 in July 2026 to 41 in August 2026 and 33 in September 2026.

The supporting metrics show broad erosion. Raw mention presence fell from 26.9% to 15.7% over the series, an 11.2-point drop. Top-three recommendation rate fell from 7.9% to 3.2%, and rank-one rate from 1.8% to 0.6%. Net sentiment eased from 0.7 to 0.5.

InCorp's decline includes a genuine presence contraction, not just a recommendation outcome shift. The benchmark records the brand appearing less often overall and being recommended less frequently within the answers where it does appear.

Highest-priority diagnostic: Which queries previously surfaced InCorp and no longer do, and what evidence or source patterns changed in those answer contexts?

Harbor Compliance

Harbor Compliance declined 2.1 points from 15.8% in August 2026 to 13.7% in September 2026, and 8.5 points from 22.2% in July 2026. The cumulative decline is significant, with valid recommendation counts falling from 98 in July 2026 to 75 in August 2026 and 69 in September 2026.

Harbor Compliance's raw mention presence held relatively steady, moving from 36.4% in July 2026 to 35.1% in September 2026, a modest 1.3-point decline within its normal range. The sharper contraction came in top-three recommendation rate, which fell from 13.4% to 9.1%. Rank-one rate fell from 2.0% to 0.6%, and net sentiment dropped from 0.7 to 0.5.

Harbor Compliance remains visible in roughly a third of qualified observations but converts that presence into recommendations less often than in July 2026, with the conversion gap widening primarily in the top-three recommendation tier.

Highest-priority diagnostic: What changed in the recommendation logic where Harbor Compliance is mentioned but not shortlisted, and which attributes or competitor comparisons are driving the shift?

Registered Agents Inc and CT Corporation

Registered Agents Inc and CT Corporation both sit at 0.4% valid recommendation coverage in September 2026, near the category floor. Registered Agents Inc declined 1.9 points from 2.3% in July 2026, a significant move on a small base: valid recommendations fell from 10 in July 2026 to 1 in August 2026 and 2 in September 2026. CT Corporation declined from 1.4% to 0.4% over the same window, with valid recommendations falling from 6 to 5 to 2.

Registered Agents Inc's raw mention presence fell from 5.9% to 2.6%, and its top-three rate from 1.8% to 0.4%. These are small-count movements where a shift of even a few observations produces large percentage changes. CT Corporation's presence fell from 4.1% to 1.6%, even as its coverage change stayed within its stable range.

The distinction to notice is fragility: both brands now operate so close to the floor that a single observation change can move their coverage percentage materially.

Highest-priority diagnostic: For Registered Agents Inc and CT Corporation, which remaining query contexts still generate any recommendation at all, and what would need to change for AI systems to recommend them beyond occasional observations?

Notable Gap: LegalZoom and the lower tier

The benchmark tracks a widening gap between LegalZoom and the category's smallest players, driven primarily by the lower tier's decline rather than by LegalZoom's movement. The gap between LegalZoom and CSC (Corporation Service Company) narrowed from 56.8 points in July 2026 to 41.9 points in September 2026, as did the gap between LegalZoom and CT Corporation, which narrowed from 55.6 to 41.9 points. The gap between LegalZoom and Registered Agents Inc narrowed from 54.7 to 41.9 points. These gaps narrowed every month across the series.

The category's spread compressed because the middle tier moved down toward the lower tier, not because the lower tier climbed. The lower tier's erosion means the gap between LegalZoom and the smallest brands is now the tightest it has been across the measured window.

Highest-priority diagnostic: Is the narrowing spread a temporary rebalancing or a longer-running pattern in how these AI surfaces structure registered agent recommendations, particularly as the lower tier approaches the floor?

Buyer-Intent Interpretation

The qualified observations for September 2026 fell entirely into the brand recommendation cluster, which captured all 504 qualified observations across all ten tracked brands. The benchmark found no qualified observations in the pricing and value or multi-brand comparison clusters across any month in the July-through-September window.

This means the current benchmark cannot yet answer questions about how AI systems characterize relative pricing, value positioning, or head-to-head comparisons. Brands competing on price or seeking to win comparative evaluations will not see those dynamics reflected in this benchmark's public metrics, even as pricing-related answer types appear in the broader answer distribution.

Brand Opportunity Summary

The benchmark identifies where attention is warranted; a company-level analysis is needed to explain why.

Evidence Behind the Benchmark

The aggregate metrics are built from prompt-level observations (query, surface, recommendation outcome, rank, sentiment, and citations where exposed). Company-level analysis can go deeper into prompt, competitor, surface, and evidence patterns. Source presence is not automatically treated as proof of causation.

Report-Specific Interpretation Notes

• Small-count movements matter: Registered Agents Inc, CSC (Corporation Service Company), and CT Corporation all operate near the floor of the category, where a shift of even a few observations produces large percentage changes.
• The qualified denominator (504 observations in September 2026) differs from the raw collection universe (800 prompts), so brand-level recommendation percentages reflect only the qualified analysis set.
• Directional analysis identifies changes worth investigating; month-over-month movement does not by itself establish cause.
• Coverage, presence, rank, and sentiment are separate signals; a brand can be widely present but rarely recommended, as LegalZoom's September 2026 data shows.

Next Step

The Public Benchmark Shows Where a Brand Is Winning or Losing. A Company-Level Audit Shows Why.

Beneath the aggregate percentages sit questions the public benchmark cannot answer: which high-intent prompts does a brand win, which competitor takes the recommendation when a brand loses, what attributes do AI systems associate with each option, and which external sources shape those answers. For a brand like LegalZoom, which lost 14.7 points of coverage since July 2026 while maintaining 82.7% presence, the commercial question is not whether it is visible but why AI systems stopped recommending it in qualifying answers.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy.
