I am wondering if tightening my max guest size to 8 would significantly reduce potential bookings or if the algorithm would simply provide more exposure to groups of 8.

For me, adding more restrictions than that will cause me a bigger loss by limiting the potential number of guests that can book.PatrickI allow 2 nights minimal for my booking too, but will allow the algorithm to fill in single days if they are orphaned.

That is a truly useless number.The basic problem is the Zillow's algorithm isn't capable of analyzing interior conditions or local (down to the street level) market conditions. 

Are occupying and profits are more about managing including being optimized in the algorithm and having the best dynamic pricing around.

@Joey Garcia my guess is you went down in the algorithms.

I would be willing to bet that most anything that has to do with Disney/Universal will be hard to find a unique and memorable name that don't already have tags and ad spend that may put you so far down in the searches/algorithms that it may not be worth it.The fact that you mentioned these will be condos makes it even more difficult to brand and stand out, there is much more competition in that space as the units are really tough to make special/unique from all of the others.

like all algorithms the more data it has the better it gets, so neighborhoods with lots of comps and similar houses get closer estimates.

Currently there are several underwriters selling a policy where the search and insuring decision is done by an algorithm, I suspect that will make title mistakes even more common. . 

If you are listed as one of the contacts.. you will end up doing a lot more co-ordination than you expect,  there is also a huge problem with their pricing algorithm... they had my lake front priced at mid 200s when ideally it should have been around 500s .per night.. took some convincing to rectify and now its priced at around 1700 per night.. which is again preposterous considering that its PA not Lake Tahoe....

Little-known Zillow hack, but their algorithm automatically pushes listings with videos to the top of the listings/featured listings and recommends it to site visitors.
