Answer
How do I reduce OTA commission costs?
Reduce OTA commission costs by shifting share to direct (the biggest lever), negotiating commission rates with priority OTAs at annual contract review, and using closed-user-group rates via member login to undercut OTAs without parity violations. A realistic shift target for independent hotels is 5-15 percentage points of direct share in twelve months, which translates to 6-18% of total revenue moving from a 15-18% commission channel to a near-zero commission direct channel.
The four levers in order of impact
One: booking engine that converts above 2.5% (the single biggest direct-share lever). Two: Google Hotel Ads with positive ROAS (typically 6-12x once the engine converts). Three: closed-user-group rates via member login (legally compliant way to undercut OTAs). Four: contract renegotiation with Booking.com and Expedia at annual review (only material above 200+ room nights per month on a single OTA).
What does not work
"Cutting OTAs entirely" rarely works for independents because OTAs supply demand discovery for first-time guests. "Hiding from OTAs by going off-portal" violates parity and risks delisting. "Bidding against OTAs on your own brand name in paid search" works but does not reduce commission; it shifts cost from commission to ad spend.
What the math looks like
A 40-room property doing EUR 1.6M annual revenue with 60% OTA share at 17% blended commission pays EUR 163,200 per year to OTAs. Shifting 10 points to direct (50% OTA at 17%, 50% direct at 0% commission but ~2% Hotel Ads cost on half the direct) saves roughly EUR 23,000 per year net. Over five years that is a EUR 115,000 cumulative saving, more than enough to fund the booking engine and ads infrastructure that produces it.
