Visa will launch a microsite for small businesses called To market the site, Visa purchased $2 million worth of Facebook advertising to give away in $100 chunks for the first 20,000 small businesses joining the site. Visa marketers are telling reporters that Facebook is full of small business, many of which depend on the site for internal communications. But this deal isn't about analytics or numbers. It's about Visa showing its hip enough to market on Facebook and a Facebook ad sales team smart enough to put a big $2 million price tag on the privilege. Put it this way: We're pretty sure somebody bought someone else a steak in order to get this deal done, and frankly, it makes us a little proud. We know moving past do-it-yourself dashboards and one-click purchases isn't easy in a Web world run by Google search advertising.
