The first year I used Smart Pricing, 2019, it really drove my prices up. Then I wrote that piece about it, and about a month later, the algorithm changed drastically and the prices only went a dollar or two over the minimum, even for busy periods, @Michelle53.
However, I think there's a cumulative effect where the more Airbnb tools you use, the better you place in rankings, and the more bookings you get. The first year I used SP I saw a 54% increase in income. Last year's longer bookings meant a lower average nightly rate but still a year-over-year increase of 20%. This year is 46% over last year. Still, SP can't take all the credit. It's a combination of SP, InstantBook, regular changes to the listing description, and generally a lot of activity - reviews, inquiries, bookings. The one thing that has NOT happened is that SP has not learned my price points. In spite of constant evidence proving my minimum results in bookings, SP never fails to suggest a much lower minimum. However, it's finally stopped saying "lower your minimum to get more bookings," so maybe we're getting somewhere.
