Wearing a purely marketing hat, badging is a pretty common way to enhance the perception of credibility. TripAdvisor, for example, rewards establishments (partucularly advertisers) with badges they can display in their place of business to show they've been rated or are otherwise promoted by TripAdvisor.
So, in that respect, it's an idea that Airbnb should consider.
However effective that may be, I, for example would take some pause at doing so, even with TripAdvisor, because digging a bit deeper, you'll find that platforms like TripAdvisor aren't quite as transparent, nor as honest as they position themselves to be. And TripAdvisor's credibility perception is starting to decline.
Airbnb's marketing is probably the single best of any platform out there. The perception they have established is in my opinion, very well done. Despite the rash of criticism that Airbnb seems to suffer ever more frequently. In fairness, as any brand becomes more successful, they'll always face increasing criticism. That's just the nature of business.
Still, I'm wary of how long it might last for Airbnb. They only need to make a few serious faux pas to cast a shadow on their brand. And judging from the apparent increase in questionable behaviours, incompetence of support, and increasing focus on sales at the expense of its base, the chances of making such mistakes seems to be increasing.
In our case, several years ago, we made the mistake of becoming too enthusiastic and dependent on Airbnb, having given up all other platforms, and exclusively listed on Airbnb, only to be ultimately spat on by Airbnb. So, we're in the process of minimising future dependence on Airbnb for our business. And we're starting to detach ourselves from being too closely associated with the brand (or any others). It could well become a liability at some point.
So, as interesting as it may be to "badge" our villa with the Airbnb logo, I'd have to have a long think about that.
But it's a truly excellent idea that Airbnb marketing should take on board.
