How AI Search Is Recommending Essential Oil: Monthly Trends

Executive Summary

Plant Therapy remains the clear category leader in AI-driven essential oil recommendations, holding 80.0% valid recommendation coverage in August 2026, up 3.1 points from 76.9% in July 2026. The gap between Plant Therapy and the next closest brand, Edens Garden, stands at 19.5 points, up from 14.0 points in July, reflecting a widening distance at the top of the category.

The category's largest upward mover this month was Plant Therapy, which posted a 9.3-point gain in top-three recommendation rate (from 56.9% to 66.2%) and a 7.7-point gain in rank-one rate (from 48.2% to 55.9%). This movement shows AI systems are not just mentioning Plant Therapy more often; they are positioning it as the primary choice in a growing share of qualified answers.

The sharpest decliner was doTERRA, whose valid recommendation coverage fell a significant 6.2 points from 30.7% in July to 24.5% in August. Vitruvi also recorded a significant decline of 3.2 points, dropping from 8.5% to 5.3% coverage. These declines stand out in a month where most other brands remained stable.

The category overall recorded movement this month, driven by Plant Therapy's strengthening and doTERRA's slide. The benchmark's notable gaps analysis shows the Plant Therapy-doTERRA gap widened by 9.3 points to 55.5 points, and the Aura Cacia-doTERRA gap flipped from a 1.5-point deficit to an 8.5-point lead, reflecting repositioning across the mid-tier.

Each monthly run begins with 800 prompt-surface observations (482 unique questions in July and 505 in August) across the benchmark's defined AI/search surface universe. Of those, 798 (July) and 799 (August) mentioned a tracked brand or competitor; 760 (July) and 771 (August) were relevant and 38 (July) and 28 (August) were irrelevant. The public metrics use the 485 (July) and 506 (August) observations 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 table below moves from that qualification funnel to the headline benchmark metrics tracked across both months.

Benchmark-Level Metrics

The valid recommendation shortlist share rose 4.3 points even as the recommendation-shaped answer share fell 3.6 points, indicating that while AI systems produced slightly fewer recommendation-shaped answers overall, a higher proportion of qualified observations yielded valid brand recommendations. The August run also included 4 pricing analysis responses and 43 comparison analysis responses, up from 1 and 35 respectively in July, pointing to a shift toward more commercial response formats in the qualified set.

AI Recommendation Trend

Plant Therapy Strengthens Its Lead While the Mid-Tier Repositions

Plant Therapy's valid recommendation coverage rose 3.1 points in August, within the range of normal month-to-month variation, while its top-three and rank-one rates rose by wider margins. doTERRA and Vitruvi were the only brands whose valid recommendation coverage moved outside that normal range, both declining, and the remaining seven tracked brands held stable positions.

What Changed This Month

Plant Therapy

Plant Therapy's valid recommendation coverage rose from 76.9% in July to 80.0% in August, a 3.1-point gain. The more striking movement was in placement: the brand's top-three recommendation rate jumped 9.3 points from 56.9% to 66.2%, and its rank-one rate rose 7.7 points from 48.2% to 55.9%.

Raw presence also strengthened, with Plant Therapy mentioned in 90.3% of qualified observations in August, up from 88.2% in July. The brand was present in 457 of 506 qualified observations and received 405 valid recommendations, meaning AI systems are converting a very high share of mentions into actual recommendations.

The distinction to notice is between visibility and recommendation strength. Plant Therapy was already the most visible brand; what changed is that AI systems are now placing it first or in the top three far more consistently than before.

Highest-priority diagnostic: Which prompt types, surfaces, or evidence sources are driving the 7.7-point gain in rank-one recommendations?

doTERRA

doTERRA's valid recommendation coverage fell a significant 6.2 points from 30.7% in July to 24.5% in August, the sharpest decline in the category. The brand's valid recommendation count dropped from 149 to 124 observations out of a slightly larger qualified set.

Presence dipped modestly, with raw mention presence at 64.8% in August, down 3.0 points from 67.8% in July. Sentiment also softened, with the net sentiment score moving from 0.4 to 0.3.

The distinguishing signal is that doTERRA lost recommendation coverage faster than presence, meaning AI systems are still mentioning the brand frequently but recommending it less often within those answers.

Highest-priority diagnostic: Which competitor is capturing the recommendation when doTERRA loses it, and which prompt clusters show the sharpest drop?

Vitruvi

Vitruvi recorded a significant 3.2-point decline in valid recommendation coverage, from 8.5% in July to 5.3% in August. The brand's valid recommendation count fell from 41 to 27, a small absolute base that makes the percentage movement more pronounced.

Raw presence declined from 10.5% to 7.3% of qualified observations, and rank-one rate eased from 2.1% to 1.6%. The brand was present in 37 observations in August and received 27 valid recommendations.

With such a small count base, the significant classification reflects a real directional shift, but the commercial magnitude should be read cautiously. Vitruvi's net sentiment score held at 0.8.

Highest-priority diagnostic: Which specific prompt categories drove the loss of 14 valid recommendations, and is this a surface-specific or category-wide pattern?

Notable Gap Movement

The benchmark flagged three widening gaps this month, all centered on doTERRA. The Plant Therapy-doTERRA gap widened by 9.3 points to 55.5 points, the Rocky Mountain Oils-doTERRA gap widened by 7.4 points to 22.7 points, and Aura Cacia moved from a 1.5-point deficit behind doTERRA to an 8.5-point lead. These movements reflect doTERRA's decline rather than a single competitor surging, and they point to a broader repositioning in the mid-tier where Aura Cacia and NOW Foods are consolidating around the 33-34% coverage level.

Buyer-Intent Interpretation

In August, all 506 qualified observations fell into the Brand Recommendation cluster, consistent with July's pattern where all 485 qualified observations mapped to the same cluster. The public benchmark therefore captures which brands AI systems recommend, and with what frequency and ranking, but it cannot yet answer price, value, or head-to-head comparison questions at the cluster level. The August run did surface 4 pricing analysis and 43 comparison analysis response types within the qualified set, indicating those response formats are present, but they have not been isolated into distinct buyer-intent clusters in the public metrics.

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 movement: Vitruvi's significant decline of 3.2 points is based on a drop from 41 to 27 valid recommendations; the directional signal is meaningful but the percentage movement is amplified by the small base.
• Qualified denominator vs raw collection: All brand-level percentages are calculated within the qualified set of 485 (July) and 506 (August) observations, not the 800 source prompts collected.
• Directional analysis: Month-over-month movement identifies changes worth investigating; it does not by itself establish the cause of those changes. Both significant decliners this month, doTERRA and Vitruvi, warrant diagnostic review rather than presumptive conclusions.

Next Step

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

Beneath the aggregate percentages lie specific questions that the public benchmark surfaces but cannot answer alone. Which high-intent prompts is a brand winning or losing? When a brand loses a recommendation, which competitor takes it? What attributes do AI systems associate with each option, and which external sources are shaping those answers? These are the questions that determine whether a coverage number reflects durable authority or a fragile position.

A company-specific AI visibility audit maps those prompt, surface, competitor, ranking, sentiment, and evidence-source patterns into a prioritized visibility strategy. It turns the benchmark's directional signals into a concrete action plan tailored to a brand's specific competitive context.
