Thank you @Debra300 This was the missing piece for me.
The “any week” search is dumb at best, it doesn’t make any sense. No one is traveling by picking out a random exactly 7-day stay 8.5 months from now. And anyone that is that flexible isn’t looking for exactly a week. It’s terribly inflexible and very old-fashioned for something that is touted as a “new way to travel”. It’s not new, it’s how people traveled 60 years ago, it’s a step backward. I’m surprised it’s not only Sat to Sat weeks. So, I understood the frustration with it but I couldn’t see how it was affecting bookings until now.
But you’ve enlightened me and I appreciate you taking the time to explain it. I guess I’ve always searched with dates. And I’ve spent a lot of time encouraging guests to search with dates because when they don’t search with dates they don’t see the real price, the cleaning fee or service fee and then complain that there are hidden fees.
I suspect that that is why it is no longer possible to search without dates. And it’s very Airbnb to overcomplicate it. They could just show “Average price” if no dates are entered like every other similar website does to avoid the hidden fees accusation. In their effort to reinvent the wheel they’ve created a useless square one.
And what you’re saying about searching without dates also explains the question that was bothering me the most: If the update is affecting bookings then why are some hosts and some places booking as usual?
And now I think it’s because some hosts get their bookings from people who search without dates, for certain types of trips that totally makes sense and now they aren’t being seen because it’s not possible to search without dates and the any week doesn't work. However, in my city, most guests come for things that have a date attached: weddings, conferences, festivals, work, etc so we’re booking as usual.
I like the idea of the categories, so I hope they fix that so that they work. I would use them but not until they are reliable, not until every listing with a view comes up under views. But they need to give the search without dates option back, it's the option that is actually flexible. That is clear now.
For your trip, as a workaround, you could use dates with the +/- option which I find very useful. For instance, I just did a test in a random place for Aug 7-14 and ticked the +/- 7 days and tripled the number of listings I was shown compared to not using the +/- option. Even if the actual dates don’t work for you, it will help you find more listings in the area you want to travel to than you’ll get with the other options.
