@David1705, I assume by asking whether something "improves bookings" you mean does it "improve your ranking in the search results".
I mean, the whole topic of improving your booking rate is of course different and larger than just improving your ranking in the search results. But if you are wondering if logging in daily and updating your calendar helps with your search ranking, AirBnB claims it does not greatly help.
I have a slighly long bunch of text I sometimes post in response to questions about how to improve a listing's search ranking, but your comment made me realize there is a larger question of how to improve your bookings. How to improve your bookings is what we really want, and that takes more than just a good search ranking. (Although certainly a very poor search ranking will torpedo any effort to get good bookings.)
Sorry to ponder about this in your comment thread. But to repeat the actual answer to your question: there are far more effective ways to improve your search rank than logging in daily to update your calendar.
(Of course, logging in daily is free, so why not?)
