Social media websites such as Facebook and Twitter make it easy for people to come together and share opinions, experiences and thoughts on a number of topics. Smart companies understand this and are using the power of social media to connect and inform their customers, and potential customers. Referred to as "Social Media Marketing", it's a smart way to open the lines of communication between you and your prospects.

Social media activities run the gamut from Blogging, micro blogging sites such as Twitter, social networking communities such as LinkedIn and Facebook, video and music uploading sites, discussion forums, photo sharing and more. With so many different sites and ways to participate, it can be difficult to keep track of all your efforts.

Participating in social media doesn't take a lot of money, but it is very time consuming and businesses want to know that all of this investment in time is paying off. Before launching a campaign, you should have a firm grasp on what it is you're trying to accomplish. Is it increasing website traffic? Getting more ezine subscribers? Having more people download your free ebook or whitepaper? Or maybe you just want to work on your company's brand image. Whatever it is, you need to have a plan. As the old saying goes, "If you don't know where you're going, you'll never get there". Have your game plan intact before getting started in marketing yourself, or your company with social media.

There are many different forms of social media, so it's impossible to use them all. Pick three or four, and funnel the majority of your efforts there. Even if you won't be working them all, at the very least you should claim your name or company name on as many social services as possible. You don't want to find out later that someone has the user name that you want. If you need to see if your chosen user name is available try which checks dozens of social media networking and bookmarking sites all at once to see if it's available. Claim your name now so you won't end up being sorry later.

So how do you monitor all the buzz? How do you monitor your brand and protect your hard earned reputation? There isn't one fool-proof method but there are many services and tools out there that will make it easy to see who's talking about you online. Some are free and others will make you pull out your wallet.
