ILIA Beauty AI Market Strategy Report - Clean Makeup Brands

Answer Capsule

ILIA Beauty recorded the largest valid recommendation coverage decline in the clean makeup category between July 2026 and September 2026, falling 8.5 points from 40.9% to 32.4%. The brand remains a visible and positively framed presence in AI-generated recommendations for clean makeup brands, but its placement quality has deteriorated sharply, with rank-one recommendations falling from 17.4% to 7.3% over the same period. The clearest win is the brand's sustained positive sentiment at 0.93, indicating AI systems still describe ILIA Beauty favorably when they surface it. The clearest weakness is the collapse in top-three and rank-one placement, which suggests competitor displacement rather than a framing problem. The clearest opportunity is diagnosing which competitors are capturing the recommendation positions ILIA Beauty previously held and rebuilding the citation and source layer that supports first-position recommendations.

Report Card

Executive Summary

ILIA Beauty entered September 2026 as a brand with strong presence but weakening recommendation conversion in AI search visibility for clean makeup. The benchmark shows valid recommendation coverage of 32.4%, down from 40.9% in July 2026, the largest decline recorded in the category over the three-month series. The brand still appears in 40.8% of qualified observations, meaning AI systems continue to surface ILIA Beauty, but the frequency with which it is placed into recommendation shortlists has fallen materially.

The brand's strongest cluster is the Best Clean Makeup Brands Discovery and Evaluation cluster, which accounts for all 645 qualified observations in the public benchmark. Within that cluster, ILIA Beauty recorded 209 valid recommendations in September 2026, down from the levels that supported 40.9% coverage in July 2026. The weakest signal is placement quality: the top-three rate fell 11.5 points to 15.3%, and the rank-one rate fell 10.1 points to 7.3%.

Across platforms, ILIA Beauty shows its strongest recommendation behavior on Copilot, where valid recommendation coverage reached 52.05%, and on Perplexity, where coverage reached 44.58%. The clearest platform gap is on Google AI Overviews, where coverage fell to 23.53%, well below the brand's overall average and far behind the category leader's performance on the same surface.

The commercial picture is one of positive framing without placement advantage. ILIA Beauty holds a net sentiment score of 0.93, among the highest in the category, yet it is being recommended less often and less prominently than in July 2026. The evidence suggests the brand is not losing because AI systems describe it negatively; it is losing because other brands are being selected in the contexts where ILIA Beauty previously appeared first.

What ILIA Beauty Is Winning

Questions This Section Answers

• Where does ILIA Beauty show its strongest evidence-backed performance in AI recommendations?
• How does ILIA Beauty's sentiment profile compare with the rest of the clean makeup category?
• What does ILIA Beauty's average recommended rank indicate about its placement quality?

ILIA Beauty's clearest evidence-backed win is its sentiment profile. The brand recorded 244 positive mentions, 19 neutral mentions, and zero negative mentions across 645 qualified observations in September 2026. Its net sentiment score of 0.93 is among the strongest in the tracked set, matching or exceeding the category leader on framing quality.

The brand also holds meaningful recommendation strength on specific platforms. On Copilot, ILIA Beauty achieved 52.05% valid recommendation coverage, the highest of any platform in its profile and a signal that certain AI surfaces continue to favor the brand. On Perplexity, the brand recorded 44.58% coverage with a rank-one rate of 9.64%, indicating that some high-intent discovery contexts still place ILIA Beauty first.

The brand's average recommended rank of 2.50 across all rank-eligible recommendations is the strongest in the category, ahead of e.l.f. Cosmetics at 2.64 and Rare Beauty at 2.82. When ILIA Beauty is recommended in a rank-eligible position, it tends to appear high in the list.

Where ILIA Beauty Has the Clearest AI Visibility Gaps

Questions This Section Answers

• How much did ILIA Beauty's top-three and rank-one placement rates decline between July and September 2026?
• Which competitors are widening the recommendation gap with ILIA Beauty?
• On which AI platforms is ILIA Beauty's public evidence layer least effective at earning recommendation placement?

The clearest gap is the collapse in top-three and rank-one placement. ILIA Beauty's top-three rate fell from 26.8% in July 2026 to 15.3% in September 2026, and its rank-one rate fell from 17.4% to 7.3%. In July 2026, ILIA Beauty was the most frequently recommended brand at rank one in the category. By September 2026, it had lost more than half of that share.

The gap between ILIA Beauty and Rare Beauty widened from 1.6 percentage points in July 2026 to 11.3 percentage points in September 2026, growing in each of the three measured months. This suggests Rare Beauty, and potentially e.l.f. Cosmetics, are capturing recommendation positions that previously went to ILIA Beauty.

The brand's presence rate also declined, from 51.4% in July 2026 to 40.8% in September 2026, meaning ILIA Beauty is being mentioned less often across all contexts. The decline is visible on Google AI Overviews, where coverage sits at 23.53%, and on Gemini, where coverage is 20.22%. These are surfaces where the brand's public evidence layer appears to be less effective at earning recommendation placement.

Biggest Opportunity

The single clearest opportunity for ILIA Beauty is rebuilding its rank-one recommendation presence in the discovery and evaluation cluster. The brand already holds the strongest average recommended rank in the category at 2.50, and its sentiment is overwhelmingly positive. The issue is not how ILIA Beauty is framed when it appears; it is how often it appears first.

The path from reference to recommendation requires identifying which high-intent prompts now return e.l.f. Cosmetics or Rare Beauty in the first position where ILIA Beauty previously appeared, then strengthening the owned content and citation sources that support first-position answers. Because the brand's framing quality remains strong, the remediation focus should be on the source footprint and answer layer that AI systems draw from when constructing recommendation lists, not on correcting negative narratives.

Competitive Landscape

Questions This Section Answers

• Which clean makeup brands hold the strongest recommendation-stage positions in the category?
• Where does ILIA Beauty rank against competitors on top-three rate, rank-one rate, and sentiment?
• What does ILIA Beauty's average recommended rank of 2.50 reveal about its recommendation pattern?

e.l.f. Cosmetics and Rare Beauty hold the strongest recommendation-stage positions in the clean makeup category, with e.l.f. Cosmetics leading at 45.58% valid recommendation coverage and Rare Beauty close behind at 43.72%. ILIA Beauty sits in fourth position at 32.40%, behind Tower 28 at 36.28%, after holding third position in July 2026.

Average recommended rank covers rank-eligible recommendations only.

The table shows ILIA Beauty holding the strongest average recommended rank in the category at 2.50, ahead of both e.l.f. Cosmetics and Rare Beauty. However, its top-three rate of 15.35% trails the two leaders by more than 6 points, and its rank-one rate of 7.29% is roughly half that of e.l.f. Cosmetics. The brand is being recommended high when it is recommended, but it is not being recommended often enough in the positions that drive buyer consideration.

Prompt Evidence

ChatGPT / Best Clean Makeup Brands Discovery and Evaluation Prompt: "best concealer" Result: ILIA Beauty appeared in the recommendation set with positive framing, but the rank-one position went to a competitor, reflecting the brand's declining first-position rate on this surface.

Google AI Mode / Best Clean Makeup Brands Discovery and Evaluation Prompt: "best tubing mascara" Result: ILIA Beauty was surfaced in the answer with a positive description, yet the recommendation list favored e.l.f. Cosmetics and Rare Beauty in the top positions, illustrating the gap between presence and placement.

Perplexity / Best Clean Makeup Brands Discovery and Evaluation Prompt: "skin tint" Result: ILIA Beauty achieved a stronger placement outcome on this surface, appearing in a rank-eligible position with an average recommended rank near the top of the list, one of the brand's better-performing contexts.

Why This Matters

Questions This Section Answers

• Why is AI-generated recommendation placement becoming critical for clean makeup purchasing decisions?
• Why is presence alone insufficient for ILIA Beauty to maintain commercial ground?

AI-generated recommendations are becoming the first filter in clean makeup purchasing decisions. When a shopper asks an AI assistant for the best clean makeup brand, the answer that comes back shapes which brands enter the consideration set and which are excluded. ILIA Beauty is still part of that conversation, but it is being recommended less often and less prominently than it was two months ago.

Presence alone is not enough. The benchmark shows that ILIA Beauty can be mentioned in 40.8% of AI answers and still lose ground because other brands are being placed first. The next move is not about improving how ILIA Beauty is described; it is about correcting the prompt, page, and citation layers that determine whether the brand earns the first-position recommendation at the moment of buyer choice.

Core Metrics

Sentiment Score

Sentiment Score = (positive mentions × 1 + neutral mentions × 0 + negative mentions × -1) / total mentions

For ILIA Beauty, the calculation is (244 × 1 + 19 × 0 + 0 × -1) / 263, producing a net sentiment score of 0.93.

This score matters because unclassified mention counts are misleading. A brand can appear in hundreds of AI answers and still be losing commercial ground if those mentions are neutral references, cautionary notes, or competitor comparisons rather than positive recommendations. Share of voice is a diagnostic metric, not a business KPI. A positive recommendation, a neutral reference, a cautionary mention, and a competitor-displaced mention are not equal, and counting all mentions as wins is bad measurement. Classified sentiment is required before interpreting AI visibility, because it separates how often a brand is talked about from how favorably it is recommended.

Sentiment by Platform

Methodology

1. This report is a benchmark-based analysis of ILIA Beauty's AI recommendation visibility in the clean makeup category, not a client implementation case study.
2. The reporting window is September 2026, with July 2026 and August 2026 referenced for movement analysis.
3. Six AI and search surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, Google AI Overviews, and Google AI Mode.
4. The benchmark began with 800 prompt-surface observations in September 2026, producing 645 qualified observations after relevance and qualification filtering.
5. The competitor universe includes 10 tracked brands: e.l.f. Cosmetics, Rare Beauty, Tower 28, ILIA Beauty, Kosas, Milk Makeup, Thrive Causemetics, Glossier, Tarte Cosmetics, and Beautycounter.
6. All 645 qualified observations fell into the Best Clean Makeup Brands Discovery and Evaluation cluster, which represents brand recommendation discovery.
7. Stage 0 extraction captured prompt-level observations including the query, AI surface, answer, brand outcome, recommendation placement, sentiment, and citations where exposed.
8. A mention is defined as any qualified observation where the brand appears in the AI response in any context.
9. A valid recommendation is defined as a qualified observation where the brand appears in a recommendation shortlist with positive framing.
10. The public benchmark does not include qualified observations in pricing, value, or multi-brand comparison clusters, so those buyer-intent classes are not measured in this report.
11. Small-count context applies to brands with fewer than 100 valid recommendations; ILIA Beauty's 209 valid recommendations provide a more stable basis for movement analysis.
12. Movement analysis identifies changes worth investigating. A brand gaining or losing coverage is a benchmark finding, not evidence of a specific cause.
