Choose a booking engine on measured conversion, not on design. Test it on a mid range phone, count the steps from room to confirmation, check that it loads in your guest's language and currency, and confirm it supports the payment methods your market actually uses. Ask every vendor for the conversion rate of hotels of your size and type before you compare price.
Most direct traffic arrives on mobile, often on a weak connection. Open the demo engine on an ordinary phone, away from office wifi, and book a room end to end. If a date picker fights you, if the page jumps while loading, or if the keyboard covers the field you are filling, your guests are meeting the same friction and leaving.
Time it. A guest who has already decided should reach the confirmation in under two minutes. Anything longer usually means fields that could be optional, an account creation step nobody asked for, or a page that reloads when it could update in place.
Every vendor claims high conversion. Ask what they count as a session, whether bots are excluded, and what the median is for independent hotels of your size in your market. A vendor who answers with a range and an explanation is being honest. A single impressive percentage with no definition behind it is a sales number.
Then measure it yourself once you are live. Your own analytics should show visits to the engine, room selections and completed bookings. Without those three numbers you cannot tell a bad engine from a bad rate OTA, using visible advantages such as member rates, flexible conditions, added perks and ">strategy, and the two are fixed in completely different ways.
Skip the research, talk to someone who has done it 45 minutes with an independent specialist. Free for hotels, no pitch, no commissions.

Check that currency display, language and date format follow the guest, and that the translation is real rather than machine output nobody proofread. A confusing rate plan, balancing booking conversion against protect">cancellation policy in broken English costs more bookings than a slow image.
Payment methods are market specific. Cards are the baseline, but bank transfer, wallets and local schemes decide whether a segment can pay at all. Line up the methods your payment provider supports against the markets in your booking mix before you shortlist anything.
The engine does not end at the confirmation screen. Check what the confirmation email looks like, whether it carries your branding, whether the reservation lands in your PMS without anyone retyping it, and how a guest modifies or cancels without calling reception.
Ask how the engine handles a failed payment and a double submission, because both happen weekly. A system that creates two reservations for one nervous guest who clicked twice will cost you a refund, a bad review, or both.
Sometimes. A bundled engine is usually cheaper and the integration is already solved, which removes a whole class of problems. A specialist engine tends to convert better and iterate faster. The honest way to decide is to compare the bundled engine's measured conversion against a specialist trial on your own traffic.
Pricing models vary between a monthly fee, a commission on direct bookings and a hybrid of both. Commission looks attractive when volume is low and becomes the expensive option as direct sales grow. Model both against your realistic direct revenue for next year before choosing.
Real scarcity information can help, such as showing that only two rooms of a type remain when that is true. Invented countdowns and fake viewer counts damage trust and, in several markets, breach consumer protection rules. If the message is not backed by your actual inventory, do not display it.
Three screens is a reasonable target: choose dates and room, add guest details, pay and confirm. Every additional screen loses part of the audience. If a step exists to collect data for marketing rather than to complete the reservation, move it to after the confirmation.
It should feel continuous, which mostly means fonts, colours and the logo. Exact visual identity matters less than staying on your own domain, because a redirect to an unfamiliar address at the payment step costs trust and bookings.
Showing them greyed out with the next available date is generally better than hiding them, because it keeps the guest on your site instead of sending them back to search. What it must never do is allow a booking the hotel cannot honour.
