Is Facebook applicable for B2B companies? Absolutely! With more than 750 million users, Facebook is useful for far more than just teenagers playing online games. The social network has become a representative sample of the world's population. As a company selling to other companies, Facebook serves as an important tool for generating leads and nurturing customer relationships.
Let's take a look at 6 B2B companies and how they are using Facebook:
6 Ways B2B Companies Are Using Facebook
1. Rewarding Brand Advocates: In the world of outbound marketing, it wasn't easy for word-of-mouth buzz to spread quickly about your business. That has all changed. Smart B2B companies now realize that "fans" can be an important part of a successful inbound marketing strategy. Cisco has taken a unique approach to rewarding some of its biggest fans. It has created a SuperFan Spotlight on its Facebook page, which rewards members of the online Cisco community who share news and information about the company. 
2. Doing Product Marketing and Promoting Testimonials: Does it get more B2B than vibration testing equipment? Fluke Corporation has gained more than 21,000 Facebook fans using some successful contests. Fluke is also a great example of a B2B company putting its product upfront in the right way in its social media marketing efforts. When you first visit the Fluke Facebook page, you are welcomed by an image about one of its featured products. In addition, the wall of the page is filled with customer testimonials.
3. Promoting News: Nothing says B2B like commercial trucking. Scania Group, a manufacturer of trucking equipment, uses Facebook to expand the reach of its news and announcements. The company hosts a newsroom on its website that acts as a hybrid between a blog and a press room. Scania uses Facebook to distribute news and industry information directly to prospects and customers, expanding its reach beyond traditional media.
4. Sharing Videos: Facebook isn't only about text. Dell Enterprise, for example, has an entire tab on its Facebook page dedicated to sharing content from its YouTube account. Videos enable B2B companies to talk about best practices and product features in a different -- and often more compelling -- forum.
5. Showcasing Experts: In B2B marketing, building credibility and thought leadership through online content creation is a key part of successful inbound marketing. GE has come up with an innovative use of Facebook to help solve this problem. Using a custom Facebook tab, GE has created a digital experts panel that displays experts as well as their newest tweet, blog post, or Facebook update. 
6. Generating Leads - The most important use of Facebook for a B2B company is generating leads and revenue for their business. One way to generate leads from Facebook is with a Like and lead gate. ClearRisk, an online provider of risk management solutions, uses the HubSpot Facebook Welcome application to encourage new visitors to their Facebook page to become a lead for their business.

Marketing Takeaway
It is clear that Facebook is a powerful tool for B2B marketers. When it comes to Facebook, set two clear priorities. The first should be setting up methods for generating leads directly from Facebook. The second should be integrating your overall inbound marketing strategy with your Facebook content and community. Look at how other B2B companies are using Facebook, but don't limit your strategies to only those that you currently observe in the market.

Are you sure that all the companies mentioned above are B2B companies? I'm not.

The company examples might not be, but the 6 ways a B2B company may use Facebook are surely relevant. Good takeaways for my company.

Oh dear - even HubSpot is now falling prey to the nonsense that there is such a thing as B2B.
Let's get this straight - B2B does NOT exist...!
There is no such thing; never has been.
If the world of social media has revealed anything it is this:
ALL business transactions are ALWAYS "P2P - Person to Person.
It does not matter whether you are buying clothes in a retail outlet or you are buying business legal services in an office - EVERY transaction is Person to Person.
Our brains do not distinguish between the concepts of B2B and B2C. The same brain activities take place.
So, if so-called B2B organisations really want to get the benefits of Facebook they need to do what the so-called B2C companies do - focus on connections with individuals.

This is exactly what I was telling a few of my SEO clients recently. When engaging with Social Media for your business you need to have a strategy and a plan in place. I like the way this article outlines that different types of ways you can disseminate information about your companies products and services. Remember to use your true voice and stick with one of these types and stay consistent. FB, Twitter and LinkedIn are just the vehicles for you to communicate from a B2B perspective. Your true voice and your subject matter expert experience is what really matters.

Thank you for using ClearRisk as an example! It's great to see what other companies are doing on their Facebook pages. And, we love the Facebook Welcome App. We finally have a way to capture leads from Facebook!

I am always weary of attributing 'social media success' with brands that have already been established. Clearly some of the top brands have done a much better job with their Facebook page and really embraced the social ideology.
I am much more interested in the development of small businesses and start-ups on Facebook. I think they give a great gauge on the possibility for building a community on social media that didn't previously exist.

Agreed Justin, think there are two angles here. Bigger companies need reach, smaller companies need engagement first.

Great information but you didn't elaborate on B2B companies more. Although the information is quite useful and can be beneficial for online business owners.
