If people want to see more customers buying things from them with Bitcoin, they could find or create a proper global but localized marketplace for that. The marketplace should be transparent and organized for mutual exchange of products and services both online and offline, with peers.

You search for local products/services and buy them from the sellers, the marketplace algorithm will inturn recommend your products/services to them (your customers, the sellers) when they search to buy them on the marketplace. If they buy from you, you could keep buying from them, and that becomes mutual and an incentive for many local buyers and sellers to join the marketplace since there are high chances of their products/services getting bought by people they buy things from.

Even though the algorithm will encourage mutual exchange of goods and services, high reputation and high quality services will be priorized such that if you don't find the quality you want from a mutual customer a better quality mutual customer will be recommended, otherwise you get a non-mutual customer for the desired quality.
Not withstanding, a mutual trade will always be top at the algorithm priority list which could encourage mutual traders to improve on quality to get  recommended more to buyers, more than non mutual customers
