Social media dashboard HootSuite has teamed up with Twitter to provide selected users with $100 in free advertising credits, part of the microblogging service's mission to woo small and medium enterprises (SMEs). The promotion, which went live yesterday, is only available to US businesses, and can only be redeemed with Twitter accounts that have not used Twitter's self-service advertising platform in the past.

The scheme is reminiscent of a deal offered when the platform launched, in which SMEs using American Express cards were given an identical amount of advertising credit. It is not clear whether Twitter has plans for any further promotions, with the decision likely to depend on how successful the HootSuite partnership proves in attracting new business.

As TechCrunch points out, this latest move follows an apparent endorsement of HootSuite made during the announcement of Twitter's controversial new API plans earlier this month. Describing the company's shifting attitude to third-party clients, product director Michael Sippey listed HootSuite among business-focused CRM providers like Sprinklr and Radian6, contrasting them with consumer-oriented clients.
