Hi @Audra-And-Bret0,
In theory the levels here, do not affect your search-ranking on Airbnb.
Having said this though. I do recall reading somewhere once: Community activity does have a positive impact on your search-ranking.
Maybe this can simply be explained by more direct referrals to your listing.
How does this work: You can bet on it, quite a few visitors of the Community here may check out the profile of a poster, followed by looking at the listing of the poster.
The statistics engine of Airbnb, may regard such a page-view as a direct referral (as if someone found the listing through Google or any other site).
It is known, the search engine to appreciate a higher level of direct referrals to a listing.
More posts (and therefore most likely a higher level in the Community here) >> More visitors of the Community looking at the listing of the poster >> Higher Search Ranking.
