Get started with your Social Media campaign with these 5 free services

1. Twitter - for businesses this is the service for communicating with your customers and building your brand awareness online. 
2. Facebook - A corporate facebook page is a great way to post latest updates, share links and post your corporate photos.
3. Blogger - well I suppose it goes without saying that I'd promote the blogging service I use! However, the two important things are to have a blog and to make it about sharing useful information that's interesting to read, rather than selling yourself in yet another medium
4. YouTube Channel - posting videos to YouTube and linking them back to your site and social media services is a great way to build back links to your site and boost your Google ranking. Googlebot loves videos :)
5. Flickr - You could argue that posting photos to Facebook achieves much the same effect and you would be right. However, the more pages that link back to your website and the more social media services you use helps to expand your exposure and reach out to as many people as possible.
