Looking at the immediate prior month, Servpro recorded the largest increase, rising 8.6 percentage points from 56.8% in September 2026 to 65.4% in October 2026, a move beyond normal monthly variation. BELFOR and ServiceMaster Restore each rose 5.5 percentage points from September 2026 to October 2026, though those moves were within normal monthly variation.

Research Scope and Qualification

Questions This Section Answers

• How many prompt-surface observations qualified for the benchmark in October 2026?
• How does the public denominator differ from the raw collection of prompts?

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

Current Brand Standings

Questions This Section Answers

• Which mold removal brands have the strongest recommendation coverage and placement in October 2026?
• How do presence, valid recommendation coverage, and rank-one rate differ across the standings?

How to Read the Standings

Presence rate measures the share of qualified observations in which a brand appears at all.

Valid recommendation coverage measures the share of qualified observations where the brand appears in a recommendation-shaped answer, regardless of position. Top-three rate measures the share where a brand appears among the top three recommendations. Rank-one rate measures the share where a brand is the first recommendation. Net sentiment scores the positive minus negative tone of a brand's mentions.

Recommendation Placement Snapshot

Questions This Section Answers

• How prominently do the leading mold removal brands appear in recommendation sets?
• Why can similar coverage rates hide different first-position outcomes?

Coverage rates show whether a brand is recommended, but not how prominently. Placement rates reveal how often a brand appears at the top of the recommendation set.

Servpro was recommended among the top three in 57.5% of qualified observations in October 2026 and was the first recommendation in 44.3% of observations. PuroClean posted a top-three rate of 23.5% but a much lower rank-one rate at 3.4%, showing that similar coverage can hide meaningfully different first-position rates. PuroClean appears regularly in recommendation sets but is rarely the first choice, while Servpro converts a much higher share of its appearances into the top slot.

Buyer-Intent Distribution

Questions This Section Answers

• What buyer-intent classes were measured in the current series?
• Which commercial questions can this benchmark not yet answer for the mold removal category?

All 294 qualified observations in July 2026 and all 327 qualified observations in October 2026 fell into the brand recommendation class.

The current public series measures brand recommendation discovery and does not yet contain qualified observations in the pricing and value or multi-brand comparison classes. This means the benchmark cannot speak to price-driven or head-to-head comparison dynamics in the mold removal category.

Historical Measurement Record

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 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 movement in any single metric does not by itself establish causality. The benchmark records change in AI discovery and recommendation patterns across the measured public surfaces. The current dataset cannot answer pricing, value, or head-to-head comparison questions because those buyer-intent classes have not yet produced qualified observations.

Top 10 Cited Domains

Questions This Section Answers

• Which domains are most cited across AI platform responses in the mold removal benchmark?
• Which tracked brand domains appear among the most-cited sources?

Across all AI platform responses in October 2026, the benchmark observed 6,405 total citations across 1,382 unique domains. The table below shows the ten most-cited domains.
