Twitter Opens Self-Serve Ad Platform to 10,000 Businesses | Digital – Advertising Age

Twitter is rolling out the self-serve ad platform it’s been testing to 10,000 small and midsize businesses next month through a partnership with American Express, in a bid to broaden its revenue streams.

Starting tonight, American Express cardmembers and merchants can register to use the platform on a first-come, first-serve basis and also receive $100 in advertising credits to put toward bidding on promoted tweets and promoted accounts — hopefully whetting their appetites for more. Twitter had begun the roll-out of self-serve, which lets advertisers make electronic payments instead of being invoiced by the sales team, in mid-November with a group of fewer than 20 advertisers and ultimately expanded the group to about 100.
