The language of hotel visibility, in plain terms

Search, AI assistants, and the booking economics behind them have their own vocabulary. Here is what the terms mean, written for hotel marketers rather than engineers, with a clear definition you can read in one breath.

AI and answer engines

How large language models and AI assistants find, read, and recommend a hotel, and what shapes whether you show up in their answers.

GEO (Generative Engine Optimisation)

GEO is the practice of making a website easy for AI assistants like ChatGPT, Gemini, Claude, and Perplexity to find, read, and recommend. For a hotel it means clean structured data, factual answerable content, and consistent details across the web, so that when a guest asks an assistant where to stay, your property is one of the ones it names.

AEO (Answer Engine Optimisation)

AEO is the practice of writing content so an answer engine can lift a clean, self-contained answer straight from your page. It favours plain language, a direct question and answer shape, and specific facts over marketing prose. A short, factual paragraph that fully answers one question is more likely to be quoted than a long, hedged page.

Answer engine

An answer engine returns a written answer to a question rather than a list of blue links. Perplexity, Google AI Overviews, and Bing Copilot are examples. For a hotel this changes the goal: instead of ranking a page, you want to be the source an answer engine cites and the property it recommends when a guest asks for somewhere to stay.

AI crawler

An AI crawler is an automated bot that reads web pages to train or inform a large language model, for example GPTBot, ClaudeBot, and PerplexityBot. Google-Extended is the related control that decides whether Google uses your content this way. If your site blocks these or hides key facts behind scripts, an assistant has less to go on, so it may miss you or describe you wrongly.

Share of Model Voice

Share of Model Voice is how often a hotel is named by AI assistants across a set of relevant questions, measured against its competitors. It is the AI-era counterpart to share of search. A high share means assistants mention you for the prompts that matter, such as the best hotels in your area, so you are present at the moment a guest is deciding.

llms.txt

llms.txt is a proposed plain-text file at the root of a website that points AI systems to the pages most worth reading, much as robots.txt guides search crawlers. It is an emerging convention rather than an official standard, and major AI systems do not yet officially consume it, so treat it as low-cost housekeeping rather than a guaranteed visibility lever.

Search and discovery

The traditional and local search foundations that decide whether a guest finds your hotel before they ever reach a booking decision.

SEO (Search Engine Optimisation)

SEO is the practice of making a website rank well in search engines like Google for the queries that matter. For a hotel that means the keywords guests actually use, fast and crawlable pages, helpful content, and signals of trust and authority. Strong SEO brings guests to your own site rather than to a third-party channel that charges commission on every booking.

Local pack

The local pack is the block of three map-pinned business listings Google shows for a location-based search, such as hotels near a landmark. Appearing here depends heavily on your Google Business Profile, reviews, and proximity. For a hotel it is prime real estate, because it sits above the regular results and captures guests who are ready to book.

Google Business Profile

A Google Business Profile is the free listing that controls how your hotel appears on Google Search and Maps, including your name, address, photos, hours, and reviews. It is one of the strongest local-search signals there is. An incomplete, inaccurate, or unclaimed profile costs you visibility in the local pack and the trust that comes with a complete listing.

Core Web Vitals

Core Web Vitals are Google's measures of real-world page experience: how fast the main content loads, how quickly the page responds to input, and how much the layout shifts as it loads. They influence search ranking and, more directly, whether a guest waits for your booking page or gives up. Slow, jumpy pages quietly lose bookings.

Schema and JSON-LD

Schema is a shared vocabulary that labels the facts on a page, such as a hotel's name, address, rating, and rooms, so machines can read them with confidence. JSON-LD is the format Google recommends for adding it. For a hotel, accurate schema helps both search engines and AI assistants describe your property correctly instead of guessing.

LodgingBusiness

LodgingBusiness is the schema.org type that specifically describes a place that offers lodging, such as a hotel, inn, or resort. Using it, rather than a generic business type, lets search engines and AI assistants understand that your property takes bookings and carries hotel attributes like check-in times and amenities, which improves how accurately you are represented.

IndexNow

IndexNow is a protocol that lets a website instantly tell participating search engines, including Bing, that a page has been added or updated, rather than waiting for the next crawl. For a hotel publishing fresh offers or content, it speeds up how quickly those changes are picked up, which matters most on a young site that crawlers visit infrequently.

The Stiplo product

The category language we use to describe what Stiplo measures, and the booking economics behind why it matters.

Commercial Integrity

Commercial Integrity is whether a hotel keeps its promises across everything a guest sees online: the website, the listings, and the AI answers about it. It asks a simple question. Can a guest find you, trust what they find, and book without friction? Stiplo measures it so the gaps that quietly send bookings elsewhere become visible and fixable.

Mystery Shop

A Stiplo Mystery Shop is an audit that looks at a hotel's public website the way a real guest and a real search engine would, then reports what it finds with the evidence behind each finding. It covers visibility and credibility today, and the report leads with the issues most likely to be costing you direct bookings.

Visibility Index

The Visibility Index is Stiplo's summary measure of how findable a hotel is across search and AI, combining where you rank for relevant queries and whether assistants surface you at all. It turns a scattered set of signals into one number you can track over time, alongside the coverage counts that show how many of your priority searches you actually appear in.

Direct booking

A direct booking is a reservation a guest makes on the hotel's own website or booking engine rather than through a third-party channel. It is the most profitable booking a hotel can take, because it carries no channel commission and keeps the guest relationship in-house. Protecting and growing direct bookings is the outcome Stiplo's checks are built around.

OTA (Online Travel Agency)

An OTA is an online travel agency such as Booking.com or Expedia that sells hotel rooms and takes a commission, often 15 to 25 percent, on every reservation. OTAs bring reach and demand, but a booking that could have come direct and commission-free instead arrives with a cut taken out. That gap is why direct visibility is worth protecting.

Metasearch

Metasearch engines such as Google Hotels, Trivago, and Kayak compare room prices across many sites at once, including OTAs and the hotel's own site, and send the guest onward to book. They are a key place where a guest decides between booking direct and booking through a channel, so the price and offer a guest sees there has to match what they find on your site.

Offer drift (coming soon)

Offer drift, sometimes called a zombie offer, is when a deal a guest is sent to has quietly changed or expired: an ad or a listing still promotes a rate that the booking page no longer honours. Catching this, by following the offer the way a guest does and checking that prices stay accurate, is a Stiplo capability in development rather than a live check today.
