Core terminology every property operator and marketer should know
The hospitality industry spans everything from room operations to guest services. Even running a small guesthouse involves a ton of specialized vocabulary across every stage of the guest journey. Mastering this terminology helps you understand industry trends and sharpen your professional edge.
In this post, we've distilled key terms used across hotels and lodging — including OTA and digital advertising jargon.
That said, this may be basic for veterans.
"Our H1 SEO and CPA performance campaigns drove a 5% lift in RevPAR. But channel-manager glitches caused repeated overbooking incidents — we need tighter PMS integration."
"Anyway, the H2 goal is to upsell this expanded guest base and raise ADR."
(Slightly clunky sentence, but bear with us.) If you understood every term in that passage, feel free to skip this post 🙂
Also: we use acronyms where they're standard in the industry, with full forms in parentheses on first mention. Terms that stay in English are kept in English.
Revenue Management Terms
(1) ADR (Average Daily Rate) and (2) RevPAR (Revenue Per Available Room) are the gold-standard KPIs for measuring a hotel's financial performance.
ADR is total room revenue divided by rooms sold. It tells you the average price at which your property sells a room. Higher ADR is obviously better — but…
…you also need to watch (3) OCC (Occupancy). A sky-high ADR means nothing if you're only filling half your inventory. That just signals overpricing and low demand.
Multiply ADR by OCC and you get RevPAR — revenue per available room. If your RevPAR lags the market average, something's off.
Managing these metrics falls under (4) RM (Revenue Management) — a specialized discipline that forecasts demand and optimizes pricing. These days, automated RM tools and decision-support software are proliferating.
For a deeper dive, check out ONDA's earlier post: "Why Revenue Management Is the Cornerstone of Hotel Profitability."
A related term is (5) Yield Management. While RM covers your entire property strategy (rooms + F&B + ancillary revenue), Yield Management zeroes in on one revenue stream — typically rooms — adjusting prices dynamically based on booking lead time.
Reservations & Check-In
The guest journey from booking to arrival. Many of these terms are self-explanatory — like (6) No-Show and (7) Overbooking.
No-Show: a guest with a reservation who never shows up. (Same usage in restaurants.)
Overbooking: accepting more reservations than available rooms. With bookings flowing in from OTAs, portals, e-commerce, your own site, and travel agents, syncing inventory across channels can fail — leading to double bookings.
(Spoiler: there's a cure for overbooking. It's called ONDA. Ahem.)
(8) Walk-In: a guest who arrives without a reservation.
Operations Terms
The industry itself is called (9) Hospitality in English — literally "welcoming and generous treatment of guests." It captures the industry's core mission: making people comfortable and happy.
(10) Housekeeping: maintaining cleanliness across rooms and facilities. The worst review a hotel can get? "It was dirty." Cleanliness is table stakes — and directly tied to reputation.
(11) Upselling: offering an existing guest an upgrade to a better room or service. Booking.com notes that upselling used to happen at the front desk, but now properties reach out before arrival via email or app — boosting ADR before check-in.
Property Management Software
Digital transformation is accelerating. (12) PMS (Property Management System) and (13) Channel Manager integrations now mean an online booking instantly updates your entire system — and every team member sees real-time property status.
ONDA offers PMS solutions for every segment: Pension Plus (small properties), OaPMS (standard hotels), and Dive (large hotels).
A modern PMS handles:
- Room setup and rate management
- Reservation creation and modification
- Daily tasks (check-in, housekeeping status)
- Analytics (transaction history, occupancy trends)
A Channel Manager syncs your room inventory across multiple (14) OTAs (Online Travel Agencies). ONDA goes further: (15) ONDA HUB not only syncs inventory but also handles sales on your behalf — a true sales partner, not just a pipe.
Online Marketing
Operators often turn to paid ads to drive bookings. Some OTAs sell fixed-price listing ads that pin you to the top of search. But venture into Naver, Kakao, or Google and you'll hit unfamiliar acronyms.
Here's a quick glossary:
(16) CPC (Cost Per Click) — you pay each time someone clicks your ad.
CPM (Cost Per Mille) — cost per 1,000 ad impressions.
CPA (Cost Per Acquisition) — cost to acquire one new customer via a campaign.
CTR (Click-Through Rate) — percentage of people who click after seeing your ad.
PPC (Pay Per Click) — same as CPC; you're charged only when the ad is clicked.
(17) SEO (Search Engine Optimization) — tuning your website content to rank higher in organic search results.
(18) SEM (Search Engine Marketing) — buying paid ads on search-engine results pages.
(19) ROI (Return on Investment) — measures campaign profitability.
(20) Retargeting — showing ads to users who previously visited your site or app.
Knowing the basics helps, but dive deeper before you spend — whether you're self-serve or working with an agency. Your marketing budget deserves that respect :)
