"take another look" emails from Air BnB

[Paul19]

As a host I often test the guest search experience and recently received this notification (below) on a propery I reviewed (that wasn't mine but in same search criteria).  During that session I also clicked into my own listing so, wondering if anyone knows the formula used to select which property is featured in this follow up email and how as a host I can ensure/improve chances that my listing is served up as it was not this last experience?

Thanks

Hi Tom,

Take another look at Upstairs "English Cottage Room" to see if it’s a good fit for your upcoming trip. You can read about the amenities and the neighborhood, and you can contact the host to ask questions.

If it's not quite right, maybe you'll like one of these similar listings.

It's a trade secret. You're not likely to get the algorithm....it actually may not be possible, because with machine learning used in today's analytics systems, there's no traditional algorithm....just patterns that the system detects, and which may change over time.
