Success in B2B social media marketing is like success in every other endeavor. It requires thought, planning, time and effort. Your social media plan must:

1. Include input from Sales. If you haven’t already, align Sales and Marketing. You can’t afford not to. Sales should be immersed in the conversations taking place with prospects offline. That information is critical to success in migrating, extending and amplifying those conversations online.

2. Be no longer than six months. You can’t plan beyond that. The conversations you need to be having with suspects, prospects and leads is influenced to a significant degree by the environment. Things change in a hurry. Your plan should define how you’ll adapt, not predict the future.

3. Develop and define target personas. Who are you trying to reach? What are their interests, needs and wants? If your content isn’t relevant and useful to that person; it won’t be consumed, remembered or acted on. You have to know, specifically, who you’re engaging in conversation. What’s relevant and useful to one person is irrelevant and useless to the next.

4. Include search engine optimization (SEO), link building, and probably paid search, too. Place your QUALITY content where your targets are congregating online; and take the extra step to PULL others to your blog and website. If they can’t find you on Google, you don’t exist.

5. Have a content strategy that doesn’t assume ‘existing resources’ will do the development. Beyond the strategy itself, this is the most important piece of the plan. Hire someone (either permanent staff or an outside consultant) as a dedicated resource… someone who is an expert at content development. That means not only an excellent copywriter, but one who has SEO skills, and one who understands how to deploy multimedia to communicate your messages quickly, clearly and persuasively.

6. Include distribution, outreach and socialization… the mechanics of how you’ll get your quality content in front of your target audience (which includes not only prospects, but influential people in your industry, in the blogging world, in the media, etc.); and give them the tools they need to comment and distribute.

7. Build in an analytics plan. List key performance indicators (KPIs). What are your goals? They should include traffic, blog comments, retweets, and conversions. This last, conversions, are where the rubber meets the road. What action(s) do you want your targets to take after consuming your content? That must be clearly defined up front. Google Analytics will give you reams of data for free. You don’t want reams of data. You want the half dozen or so stats that will give you a good idea of how well the plan is meeting its goals.

8. Serve existing customers. It’s easier to keep existing customers than it is to obtain new ones. Does your social media marketing plan lay out how you’ll keep your current customers informed and happy? Social media isn’t only a marketing tool. It’s also an excellent research, customer service and PR tool. Make sure your plan leverages it across all those departments.

9. Include Facebook along with Twitter, LinkedIn, and Foursquare. There are so many people on Facebook you’d be crazy not to try to reach .01% of them. Also look at niche social networks that may aggregate your targets. Once the content is developed, there are tools that automate the process of distributing to these platforms.

10. Follow through. After the content is distributed, you have to follow through. Your social networks must be monitored; and questions and comments must be answered. That’s the essence of  conversation. Listen.

11. Build your house list. It’s your most valuable marketing asset. Your plan should include integration of the various social media platforms into your Customer Relationship Management (CRM) system.

12. Include a feedback loop. You developed relevant and useful content for your target audience. You distributed it. You socialized it. You listened and gathered intelligence re what your target thinks of your messaging. You’ve seen which content drives traffic and conversions, and which doesn’t. Feed that information back into the plan. Tweak, and repeat.

13. Be reasonable. There’s a perception that social media is low cost. The price of admission is practically zero, but social media marketing is a process. It requires a significant investment of time. You must listen, participate, and converse over time. Budget money and other resources accordingly.

14. Do the math. The easiest way to check on #13 is to do the math. Your social media plan should put a dollar value on a customer, and provide a worst-case cost estimate for acquiring that customer. Your customer acquisition cost, using social media, should be no more than a few percentage points of the lifetime value of that customer. If it isn’t, something is wrong with either your plan or your pricing.
