Make Lemonade Proprietary Framework
Signal Noir™ AI Authority Framework
for Luxury Travel Brands
What is Signal Noir™
The AI Authority Framework
Built for Luxury Travel.
Signal Noir™ is a proprietary AI authority framework developed by Make Lemonade. It tests how real luxury traveller personas, configured around your brand, your guest types and your competitor set, search for and choose between brands across AI platforms. The output is a precise, repeatable picture of where a brand is being recommended, where it is being overlooked, and exactly why.
Most hotel marketing measurement focuses on what happens at the bottom of the funnel: clicks, conversions, bookings. Signal Noir™ measures what happens before that, at the moments where a guest, a travel journalist, or an AI system like ChatGPT or Perplexity first forms an opinion about a brand.
Traditional models measure hotel performance at the point of conversion. Signal Noir™ measures performance at the point where travel decisions are shaped.
The Key Insight
AI authority is not evenly distributed across the funnel.
Most luxury brands are over-invested in the stage where it matters least.
AI systems like ChatGPT, Perplexity and Google AI Overview now cap hotel recommendations at a handful of results. The luxury travel brands appearing in those results are not always the best known, they are the ones that built the right authority signals at the right stages. Signal Noir™ shows where those signals are missing for your brand.
How Signal Noir™ Works
Structured Testing. Configured Around Your Brand.
Signal Noir™ does not rely on assumptions or generic benchmarks. It runs structured tests using luxury traveller personas and query sets built specifically around each client, the guest types that matter to that brand, the queries those guests actually ask AI systems, and the competitors that brand is measured against.
The persona mix, query categories, AI platforms and testing frequency are all agreed as part of the brief. The result is AI authority data that is directly relevant to your brand, not a generic industry benchmark that tells you nothing about your specific situation.
01
Which publications AI is citing per query category
A clear map of which titles are driving AI recommendations for your specific guest types and query categories, so PR investment can be directed at the publications that actually move the needle, not just the ones with the highest prestige.
02
Whether your citation rate has moved
A precise, comparable metric showing whether your brand’s appearance in AI responses has increased, decreased or held steady, and which specific queries, platforms or persona types are driving that change.
03
Which content formats drove changes
Signal Noir™ identifies whether shifts in AI citation share were driven by editorial coverage, owned content updates, structured data changes or competitor activity, so the cause is always understood, not just the outcome.
04
How your position compares to your competitor set
Every report benchmarks your brand against the specific competitors you define, whether that is other luxury hotel groups, airline travel content, or lifestyle publications in your space, so you know whether gains are absolute or relative.
The Decision Influence Model
How Luxury Hotel Brands
Build AI Authority.
The personas Signal Noir™ tests cover all four stages of the guest decision journey. AI authority is built upstream and converted downstream. Most brands only measure the downstream.
01
Authority Origination
Inspiration
Editorial coverage in high-authority travel and luxury publications that shape how a brand is first encountered. The stage where AI citation signals are created.
What personas reveal hereEarly-stage personas search broadly, “best luxury safari lodges” or “most exclusive island resorts.” Being cited in these responses sets the foundation for everything downstream.
02
Citation & Corroboration
Discovery
How a hotel brand surfaces when a guest searches via Google, ChatGPT, Perplexity or travel advisor recommendations. The stage generative engine optimisation (GEO) most directly affects.
What personas reveal hereDiscovery personas compare, “which is better, Aman or Rosewood?” or “top luxury hotels for honeymoon in Maldives.” The query mix is configured to match your actual competitive landscape.
03
Interpretation & Clarity
Consideration
The moment a potential guest evaluates. Structured content, a clear brand narrative and consistent owned media determine whether a luxury brand advances or is discarded here.
What personas reveal hereConsideration personas ask specific questions about a brand, food, service, facilities, suitability. Accuracy and consistency of owned content is critical at this stage.
04
Conversion Capture
Decision
The booking, the enquiry, the direct contact. Most luxury hotel brands invest heavily here. Signal Noir™ reveals how much of this outcome was determined two or three stages earlier.
What personas reveal hereDecision personas are ready to act. Brands that were visible in stages 1–3 win here, without paid media, and without competing on OTAs.
The AI Brand Authority Matrix
Where Does Your Hotel Brand
Sit in AI Search Right Now?
Most luxury travel brands assume strong PR means strong AI authority. The Signal Noir™ matrix, built from structured persona testing, shows whether that assumption holds, and where the gaps are costing bookings.
Top Left
Early Authority, Lost Value
Strong PR coverage and media presence, but poor owned content structure means AI systems reference the brand without prioritising it in recommendations. Strong editorial authority, weak AI authority signals. Persona testing reveals this gap immediately.
Top Right, Target Position ★
Dominant Influence
Strong authority across all four stages. Consistently cited in luxury travel editorial. Frequently recommended by ChatGPT, Perplexity and Google AI Overview across multiple persona types and query categories. These brands are recommended before the guest reaches a booking site.
Bottom Left
Invisible
Weak across all stages. Minimal editorial presence in AI-cited publications. Poor generative engine optimisation signals. Not appearing across the persona and query mix tested, and not in Google either.
Bottom Right
Conversion-Led, Influence-Poor
Strong at the decision stage through paid media and OTA presence. Limited editorial authority. Rarely surfaced in AI-led travel discovery. Captures booking demand it did not create, and pays heavily for the privilege.

AI Authority Strength: Low → High
Luxury hotel brands don’t win at the point of booking. They win in the AI recommendations that shape it.
What a Signal Noir™ Audit Delivers
Three Things Your
Brand Can Act On Immediately.
A Signal Noir™ audit is not a report for its own sake. Every engagement ends with a clear, prioritised plan.
01
Identify exactly where AI authority is breaking down
A clear picture of where across your specific persona and query mix AI authority is being lost, whether the cause is editorial gaps, content structure issues, AI-uncrawlable media placements, or inconsistent brand data across platforms.
02
Focus PR and GEO investment where it will actually move recommendations
Rather than spreading budget across every channel, Signal Noir™ identifies the specific publications, content types and platforms where investment will have the greatest impact on AI citation share, based on how your actual guest personas search, not industry averages.
03
Prove that editorial coverage drives direct hotel bookings
By mapping AI authority across all four stages and your defined persona set, Signal Noir™ creates a traceable connection between editorial authority, generative engine optimisation and commercial conversion, the evidence most luxury hotel brands cannot currently produce.
Signal Noir™ In Practice
Which Luxury Travel Publications
Are Actually Influencing AI Recommendations?
The first major published application of Signal Noir™ is a research study scoring thirty leading luxury travel and lifestyle publications, produced in association with Spotlight Communications. It applies a defined persona and query mix to reveal which publications are building real AI citation share for luxury travel brands, and which ones look prestigious but go uncited by ChatGPT, Perplexity, Claude and Gemini.
Published June 2026
Invisible or Influential? — What the research found.

Common Questions
FAQs About AI Authority
for Luxury Travel and Hospitality.
What is AI authority for luxury hotels?
AI authority for luxury hotels refers to the strength of the signals that influence whether a hotel is cited and recommended by AI systems like ChatGPT, Perplexity or Google AI Overview. Unlike traditional SEO which focuses on Google rankings, AI authority depends on editorial citation patterns, structured content and consistent brand data across high-credibility sources. Hotels with strong AI authority are recommended before a guest ever visits a booking site.
What is generative engine optimisation (GEO) for hotels?
Generative engine optimisation (GEO) for hotels is the practice of structuring content, editorial presence and digital data so that AI systems like ChatGPT and Perplexity cite and recommend a hotel in their responses. For luxury hotels, this means building authority across high-credibility publications, structuring owned content clearly, and ensuring consistent accurate data across all platforms AI systems reference. Signal Noir™ maps current GEO performance and identifies where to focus.
How does Signal Noir™ use personas to test AI authority?
Signal Noir™ runs structured tests using luxury traveller personas and query sets configured specifically around each client’s brand, guest types and competitor set. The persona mix, query categories, AI platforms and testing frequency are all agreed as part of the brief. The output shows which publications AI is citing per query category, whether citation rates have moved, which content formats drove changes, and how the brand compares to its defined competitor set.
Why is my luxury hotel not appearing in AI recommendations?
The most common reasons a luxury hotel does not appear in AI recommendations include: editorial coverage placed in publications that AI systems do not actively cite; website content that is difficult for AI to parse; inconsistent brand data across third-party platforms; and a lack of structured content that clearly signals what the hotel is and who it is for. Signal Noir™ persona testing identifies exactly which of these gaps is causing the problem, and for which guest type.
What is the difference between AI authority and traditional hotel SEO?
Traditional hotel SEO focuses on ranking in Google search results. AI authority is about whether AI systems surface and recommend a hotel when guests research travel options conversationally. The signals that drive AI recommendations differ from traditional SEO: editorial authority, AI-crawlable content structure and citation patterns in trusted publications all play a significant role alongside standard technical SEO factors.
Which luxury travel brands does Signal Noir™ work for?
Signal Noir™ is designed for luxury hotels, resorts, destination management companies, travel agencies, airline loyalty programmes and lifestyle brands where editorial authority, AI discovery and reputation all affect commercial outcomes. It is particularly valuable for brands that invest significantly in PR but cannot trace that investment back to AI recommendations or direct bookings.
Can Signal Noir™ be used by PR agencies on behalf of clients?
Yes. Make Lemonade works directly with PR and communications agencies in two ways: white-label delivery, where we run the Signal Noir™ audit and the agency delivers the output under their brand; and referred engagements, where we work alongside the agency team. Either way, the client relationship stays with the agency. Signal Noir™ gives agencies a measurable, data-led way to demonstrate the AI authority impact of their editorial and PR work.
Can Signal Noir™ be used to audit a publication rather than a brand?
Yes. The Signal Noir™ framework was used to score 30 leading luxury travel and lifestyle publications in the
Invisible or Influential? whitepaper, produced with Spotlight Communications in June 2026. Publishers use Signal Noir™ to understand their AI citation position, benchmark against peer titles, and build the commercial case for their editorial authority in conversations with brand partners.
