You do not have to be a large or multi-national brand to succeed in social media marketing.
All it takes is a strategy and some effort.
For social media fresh content is even more important than for a "regular" website — you really have to keep your fans, followers and friends engaged.
Polls, surveys and social media specials are only a few of the incentives you can use to interact with your visitors. If you never before experimented with video, why not start by releasing video testimonials? Or how-to-information?
If you meet clients or prospectives at events, connect with them on LinkedIn or facebook after the event.
Remember: Social media is not for people with too much time anymore, it has become a huge part of the overall online experience. Use it to your advantage!
