Hello @Karody0 ! In addition to maybe offering a discount (as mentioned previously), here are a couple thoughts...
When I first listed my (very modest!) Airbnb suite two years ago, I also found that after an initial boost, reservations slowed down. New listings get extra promotion at first! I don't actually know how the algorithms work, but what I have found is that if I constantly make updates and interact with the Airbnb interfaces, I can maintain momentum.
I'm just assuming the following efforts, done on a routine basis, positively impact guest reviews & the algorithms (but they do positively impact guest and host experiences!): make improvements to the space, update & improve photos, check how the listing appears to viewers and adjust & improve as needed, compare how my listing stacks up to other similar listings, communicate proactively before/during/after bookings, participate in this community center, follow up on every piece of feedback from guests, and more. Your 4.86 rating is really positive. With a few tweaks, I bet you could get ratings even higher than that! Higher review ratings would definitely boost your appearance in search results for potential guests. Best wishes!
