How to promote direct booking website to Airbnb guests without violating terms?

[Isaac Wiinanen]

I've read some great threads on the benefits of direct booking, strategies to get traffic via social media, etc.

The one thing that isn't 100% clear is how to market your direct booking website to current Airbnb guests (e.g. via a printed sign or QR code in the unit advertising direct booking as an option) without running the risk of Airbnb pulling your listing. Per the Off Platform Policy article below you cannot "[ask] or [encourage] guests to book outside of Airbnb for repeat or future bookings"

I am still highly interested in pursuing the direct booking option, so are there any methods that are either (a) Airbnb compliant or (b) clever enough to prevent suspension?

Thanks!
