Cohen says that content will be more shareable this year. Entrepreneurs should be ready to distribute content through social media, third-party sites, widgets, smartphones, and more.

Post-purchase marketing will also be significant in 2010. As Americans still struggle with personal finances, offering consumers post-purchase support emails will increase the profitability of current customers. She advises entrepreneurs to think about how to add value to offerings with products that can be sold post-purchase.

There will also be a new sophistication to social media marketing. While 2009 was a time when SMBs felt productive simply creating a Twitter account or Facebook page, 2010 will be a time to increase efforts to maximize the efficacy of these tools. Entrepreneurs should focus on creating greater transparency of their brand across all of these platforms.

Fine-tuning social network campaigns could be an important strategy for small businesses, as eMarkter predicts that marketers will spend more than $2 billion on social media this year.
