This is deliberately vague and will require patience to see results. It is not an (A + B) x C = Retirement/fire-the-ad-agency in 6 months kind of plan.
- Social media is social. Think about what kind of social event your company would host. The same rules of engagement & conversation apply. My personal style of social event would be a bbq. I would let people swear a bit (ok, a lot), but not be (overly) offensive to other guests. I would occasionally talk about the fun things I had done lately at work, or interesting things in the industry. I would not hand out business cards or openly solicit new business. Think about what social event you would have with your clients/providers/friends etc. Dinner party? Golf day? High tea? Whatever suits your brand's personality. Think about what kind of conversations you would have at this event. Replicate this same style of engagement on your social media platforms.
- Build a vocabulary of words to use more frequently in your social media/blog posts. Make these words representative of the way you want your company to be perceived. They will give your brand a controlled personality that will show you in a desired light, and help potential customers (and future employees) align themselves with your brand. This is my personal brand on Twitter as a tweet cloud. The bigger the word, the more frequently I use it: http://tweetcloud.com/search/from/antsgardiner
- Be consistent with the timing & content. If you use your twitter account to tell jokes, do not suddenly change to a marketing push and vice versa. And by timing I mean do not forget about twitter for 3 weeks then suddenly send 20 tweets in a day (or FB updates, or blog posts etc). A content plan can help with this. When I ran SM for the military I had 3-6 months of content planned in advance, but I was always flexible with that and would talk about other content as it became topical.
- Social media is two way. Do not think about what message you want to shout, think about what conversation you want to have, and who you want to talk with. Social media, and in particular Twitter, should be viewed more as a customer service channel, NOT a marketing channel. If you publicly treat your audience well with these channels, they will do your marketing for you in a word of mouth way that is more powerful than any message you could push out yourself.
- Facebook tabs can do anything these days. ANYTHING. Here is one I built that broadcasts live TV while also displaying a twitter feed of related comments and allowing people to discuss what is happening via Facebook comments: http://www.facebook.com/skinnymarketing?sk=app_104908912928390 You can build a tab that does anything you want, and use these to give your audience a reason to stick around, and a reason to talk about you.
- Use your Facebook insights page to learn about your main audience segments. Use other statistical information and sites like www.klout.com to identify the mass influencers within your audience and target ads (above the line, plus sm ad campaigns like FB ads or Twitter promotions) directly to this group to get the best bang for your buck.
If patience is not your virtue, there is always the option of running a big flashy promotion. Just make sure you follow the rules....
