Answer Capsule

Tower 28 holds third position in clean makeup AI recommendations with 36.3% valid recommendation coverage in September 2026, down 0.8 points from July 2026. The brand is surfaced in half of all qualified observations but converts that presence into top-three placement at a rate below the category leaders. Its clearest strength is a strong presence rate of 50.4% with no negative framing across tracked platforms. Its clearest weakness is a low rank-one rate of 2.5%, indicating the brand is frequently mentioned but rarely chosen first.

Executive Summary

Tower 28 holds a stable third-place position in clean makeup AI recommendations with 36.3% valid recommendation coverage in September 2026, down 0.8 points from 37.1% in July 2026. The brand peaked at 39.2% in August 2026, meaning its September figure represents a 2.9-point pullback from the prior month. The brand remains classified as stable overall, but the monthly pattern shows an August peak followed by a September retreat.

The brand recorded 234 valid recommendations out of 645 qualified observations, with 325 total mentions. Sentiment is strongly positive at 0.8492, with 276 positive mentions, 49 neutral mentions, and zero negative mentions across the tracked set. The brand's strongest platform signal comes from Gemini, where it holds 41.6% valid recommendation coverage and a 5.6% rank-one rate, the highest rank-one rate the brand achieves on any platform.

The clearest gap is at the top of the recommendation structure. Tower 28's presence rate of 50.4% is the third-highest in the category, but its rank-one rate of 2.5% places it in the middle of the tracked set rather than near the top. The brand is being surfaced in half of all qualified observations, yet it is rarely the first recommendation AI systems offer.

The weakest platform signal is ChatGPT, where Tower 28 records zero rank-one recommendations across 80 observations despite a 60.0% presence rate. The brand appears frequently in ChatGPT answers but is never placed first, suggesting a recommendation conversion problem specific to that surface.

What Tower 28 Is Winning

Questions This Section Answers

  • What is Tower 28's clearest strength in clean makeup AI recommendations?
  • Where does Tower 28 show its strongest platform-level performance?

Tower 28's clearest win is its absence of negative framing. The brand recorded zero negative mentions across all tracked platforms in September 2026, a distinction shared with only a few competitors in the tracked set. Its net sentiment score of 0.8492 reflects consistently positive framing when the brand is mentioned.

The brand also holds a strong presence position. Its raw mention presence rate of 50.4% is the third-highest in the category, behind only Rare Beauty at 66.0% and e.l.f. Cosmetics at 61.4%. Tower 28 is being surfaced in half of all qualified AI observations, which provides a substantial base for recommendation conversion.

Gemini is a meaningful pocket of strength. Tower 28 achieves 41.6% valid recommendation coverage on Gemini, its highest coverage rate across all tracked platforms, with a 5.6% rank-one rate and a 17.98% top-three rate. The brand also holds a 56.2% positive visibility rate on that platform, its strongest positive framing anywhere in the tracked set.

Where Tower 28 Has the Clearest AI Visibility Gaps

Questions This Section Answers

  • Why is Tower 28's presence-to-rank-one conversion the weakest among the top five brands?
  • What is the clearest platform-specific weakness in Tower 28's recommendation profile?

Tower 28's central gap is the conversion of presence into top placement. The brand is mentioned in 50.4% of qualified observations but appears first in only 2.5% of them. By comparison, e.l.f. Cosmetics holds a 61.4% presence rate and converts it into a 14.3% rank-one rate, while Rare Beauty holds a 66.0% presence rate and achieves a 6.0% rank-one rate. Tower 28's presence-to-rank-one conversion is the weakest among the top five brands by coverage.

The ChatGPT gap is the clearest platform-specific weakness. Across 80 ChatGPT observations, Tower 28 is present in 60.0% of answers but records zero rank-one recommendations and only an 8.75% top-three rate. The brand is being surfaced consistently on ChatGPT but is never the first recommendation, indicating that other brands are capturing the top position in the answers where Tower 28 appears.

The brand's average recommended rank of 3.66 also signals a placement problem. When Tower 28 is recommended, it tends to appear lower in the shortlist than its coverage rate would suggest. The category leaders hold average recommended ranks near 2.6, while Tower 28 sits closer to the middle of the recommendation list.

Biggest Opportunity

Questions This Section Answers

  • What is Tower 28's biggest opportunity for improving its AI recommendation position?

Tower 28's clearest opportunity is converting its high reference rate into stronger top-three and rank-one placement on ChatGPT. The brand is present in 60.0% of ChatGPT answers but never appears first, and its top-three rate on that platform is less than half its overall average. This is the single largest gap between presence and recommendation conversion in the brand's profile.

The path forward is to identify which ChatGPT prompts surface Tower 28 as context rather than as a chosen option, then build the owned answer layer and citation architecture that positions the brand as the first recommendation in those high-intent discovery moments. The brand already holds the presence base; the missing piece is the recommendation-stage evidence that moves it from mentioned to selected.

Prompt Evidence

Questions This Section Answers

  • What do the platform-specific prompts reveal about how Tower 28 is being surfaced versus selected?

Gemini / Best Clean Makeup Brands Discovery & Evaluation Prompt: "What is the best blush on the market?" Result: Tower 28 appears in the recommendation shortlist with its strongest platform-level rank-one rate of 5.6%, indicating Gemini surfaces the brand as a viable option in product-specific discovery prompts.

ChatGPT / Best Clean Makeup Brands Discovery & Evaluation Prompt: "What is the most popular makeup brand?" Result: Tower 28 is present in 60.0% of ChatGPT answers but records zero rank-one recommendations, suggesting the brand appears as context or comparison rather than as the selected first option.

Perplexity / Best Clean Makeup Brands Discovery & Evaluation Prompt: "best setting spray" Result: Tower 28 achieves 36.1% valid recommendation coverage on Perplexity but a 0.0% rank-one rate, indicating the brand is shortlisted regularly yet never placed at the top of the answer.

What CiteWorks Studio Would Do Next

Phase 1: AI Market Discovery Audit Map which high-intent prompts surface Tower 28 as a mention versus a recommendation, with particular focus on ChatGPT where the presence-to-rank-one gap is widest.

Phase 2: Recommendation Readiness Plan Identify the product categories and prompt types where Tower 28 is shortlisted but not selected first, then prioritize the discovery moments with the highest commercial value.

Phase 3: Owned Answer Layer Buildout Develop product-level content that gives AI systems clear, citable reasons to place Tower 28 first in response to specific clean makeup discovery prompts.

Phase 4: Citation / Authority Layer Development Strengthen the external source footprint that supports Tower 28's recommendation eligibility, focusing on the evidence layer AI systems appear to synthesize when building shortlists.

Phase 5: Monthly AI Visibility and Recommendation Tracking Track whether the presence-to-rank-one conversion gap narrows across ChatGPT and other platforms as the owned answer and citation layers mature.

Why This Matters

Questions This Section Answers

  • Why does being mentioned without being ranked first matter for Tower 28's commercial outcomes?

AI systems are surfacing Tower 28 in half of all clean makeup discovery answers, but they are rarely choosing the brand first. In buyer-choice terms, the brand is on the shortlist without winning the decision moment. That distinction matters because the first recommendation in an AI answer carries disproportionate influence over which brand a shopper explores next.

The next move is not broader visibility. Tower 28 already has that. The next move is targeted correction of the prompt, page, and citation layers that determine whether the brand is mentioned as an option or recommended as the answer.

Sentiment Score

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

For Tower 28, the calculation is (276 × 1 + 49 × 0 + 0 × -1) / 325, producing a net sentiment score of 0.8492.

This matters because unclassified mention counts are misleading. A brand can appear frequently in AI answers while being framed negatively or as a cautionary example, and raw mention volume would hide that distinction. Share of voice is a diagnostic metric, not a business KPI. A positive recommendation, neutral reference, cautionary mention, and 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 reveals whether a brand is being recommended, referenced, or warned against.

Methodology

  1. This report is a benchmark-based analysis of Tower 28's AI recommendation visibility in the clean makeup category, produced from the LLM Authority Index AI Market Discovery Index and CiteWorks Studio interpretation of that public benchmark data. It is not a client implementation case study.
  2. The reporting window is September 2026, with comparison references to July 2026 and August 2026 baseline and intermediate months.
  3. Six canonical AI and search surface families were tracked: ChatGPT, Copilot, Gemini, Perplexity, AI Overviews, and AI Mode.
  4. The benchmark began with 800 prompt-surface observations in September 2026, of which 699 were relevant to the vertical and 645 qualified for the public denominator after two qualification stages.
  5. The competitor universe includes 10 tracked brands: Beautycounter, e.l.f. Cosmetics, Glossier, ILIA Beauty, Kosas, Milk Makeup, Rare Beauty, Tarte Cosmetics, Thrive Causemetics, and Tower 28.
  6. All 645 qualified observations in September 2026 fell into the Brand Recommendation buyer-intent class. The public benchmark does not yet contain qualified observations in pricing and value or multi-brand comparison classes.
  7. Stage 0 extraction captured prompt-level observations including 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 answer in any context, whether recommended, referenced, or compared.
  9. A valid recommendation is defined as a qualified observation where the brand appears in a recommendation shortlist. Negative, neutral, cautionary, comparison-anchor, and listed-only mentions are not counted as valid recommendations.
  10. Brand-level percentages use the 645 qualified observations as the public denominator, not the raw collection of 800 prompts.
  11. The public benchmark does not measure market share, sales attribution, organic-search ranking performance, social media volume, or private channels. Source presence is evidence about the information environment, not proof of causation.
  12. Limitations: Small-count brands carry more month-to-month variance. Movement analysis identifies changes worth investigating, not evidence of specific causes. The public benchmark measures which brand gets recommended, not how AI systems frame trade-offs on price, value, or direct comparison.

Understanding AI search visibility.

AI search experiences create answers by pulling information from many places online and summarizing it into a single response.

What Is AI Citation Intelligence?
AI citation intelligence is the process of measuring where AI platforms source their information and how frequently a brand is mentioned or referenced in AI-generated responses. Because LLMs synthesize across multiple sources, the sites and brands that appear repeatedly tend to influence how a topic or company is framed. This practice focuses on identifying which sources shape AI outputs and tracking brand visibility across different AI systems.
What Is Citation Architecture?
Citation architecture describes the set of sources that consistently inform how AI systems talk about a brand, product, or topic. LLMs draw from websites, articles, forums, and public discussion, and the sources they rely on most often become the backbone of their answers. Building strong citation architecture means ensuring that accurate, credible, high authority sources are the ones most likely to shape the way AI tools summarize and recommend a brand.
What Is Generative Engine Optimization?
Generative engine optimization (GEO) is the practice of improving the chances that AI systems use and cite your brand or content when generating answers. While traditional SEO is centered on ranking pages in search results, GEO focuses on how LLMs retrieve, interpret, and combine information when responding to a question. The objective is to strengthen the content and sources AI systems rely on, so your brand is treated as a trusted reference in AI responses.
What Is AI Share of Voice?
AI share of voice tracks how often a brand appears in AI-generated answers compared with competitors in the same category. It reflects visibility across AI platforms such as ChatGPT, Gemini, Claude, and Perplexity. Monitoring AI share of voice helps organizations see whether AI systems consistently include and recommend their brand for key queries or whether competitor brands are showing up more often.
