What sells on a live stream for pet?
Things with a decision in them. An item somebody is uncertain about — fit, size, quality, how it behaves — sells on a stream, because the stream answers the uncertainty in real time.
What sells, and what does not
What does not sell is the commodity line the buyer can price-compare in ten seconds. Putting it on a stream turns an hour of attention into a comparison shopping session.
Live selling works where the product has to be seen moving, worn or demonstrated, and does little where it does not. For a pet supplies store in the UAE, the answer turns on one thing in particular: Pet food is the most reliably repeated purchase in retail: the bag runs out on a known schedule.
What is different about the UAE
Delivery expectations in the UAE are set by same-day services, so five-day shipping reads as slow whatever the price.
Card payment is the norm in the UAE, with cash on delivery still expected by a meaningful minority.
What is different about a pet supplies store
The work is not the video. It is buying inside the video, because a link to a product page loses most of the audience.
Where a mobile app comes into it
This is the clearest case for an app of any category. TicApp built barcode reordering into Pets Lounge for exactly this.
