Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design. The funnel below shows how raw prompt-surface observations become the qualified benchmark.

Brand-level percentages use the qualified observations as the public denominator, not the raw collection. See the AI Market Discovery Methodology.

IONOS posted the largest single-month decline at 8.3 points, moving from 61.3% in August 2026 to 53.0% in September 2026, a decline classified as beyond normal variation.

Largest Decline: IONOS

The brand's presence rate also fell from 76.8% in July 2026 to 69.7% in September 2026, and its top-three rate declined from 35.4% to 23.6% over the same period. IONOS remained the category leader despite the decline.

The two-month decline of 8.6 points was classified as significant. The brand's top-three rate fell from 16.2% in July 2026 to 10.6% in September 2026 over the same period.

Significant Decliner: Bluehost

Category Leader: IONOS

IONOS remained the category leader with valid recommendation coverage of 53.0% in September 2026, down from 63.9% in July 2026. The gap to the second-place brand narrowed from 7.1 percentage points to 3.0 percentage points between July and September 2026. InMotion Hosting posted the largest coverage increase among stable brands, moving from 32.6% in July 2026 to 33.9% in September 2026. OVHcloud rose in each of the two months, moving from 7.0% in July 2026 to 7.9% in September 2026, though the move remained within normal month-to-month variation.

Recommendation Placement Snapshot

Coverage alone does not show how prominently a brand is recommended. The leading cluster by valid recommendation coverage shows different placement profiles.

While IONOS led the category in coverage, Bluehost held the higher top-three rate in September 2026 at 29.1% compared with IONOS's 23.6%. Liquid Web posted the highest rank-one rate among the leading brands at 6.9% in September 2026, despite lower overall coverage. DreamHost's top-three rate of 10.6% in September 2026 translated into a rank-one rate of just 0.2%, showing that similar coverage levels can still hide very different first-position rates.

Buyer-Intent Distribution

All 492 qualified observations in September 2026 fell into the brand recommendation class, the same as July 2026 when all 488 qualified observations fell into that class.

The current public series measures brand recommendation discovery only; pricing, value, and multi-brand comparison questions have no public signal in this data.

Historical Measurement Record

This is an evergreen benchmark URL. New measurements are added to the same report.

Evidence and Source Layer

The 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 the source caused the 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 and sponsored channels. A metric movement alone does not establish causality; the benchmark records the change and does not, by itself, explain why the change occurred.
