Although it’s the height of social media, don’t make the mistake of thinking Facebook isn’t a place to do business. Worldwide, more than 1.2 
billion people use Facebook every month. That’s a 15% increase in just one year. Of that number, a little over 800 million check in with the website every single day. This represents an increase of 21% from the year prior. If you can’t make those kinds of numbers work to your advantage, maybe eCommerce isn’t for you. Fortunately, the below methods will help.
First, let’s address the advertising option on Facebook. As the social media website knows so much about its users, Facebook is a great place to run ads. You can drill down to all kinds of aspects: gender, relationship status, education level, current location, etc. Nothing else on the Internet can promise that your ads will get seen solely by your demographic, meaning you’re not paying to be viewed by people who aren’t a part of it.
Furthermore, advertising on Facebook is incredibly affordable. The cost-per-click is competitive with just about any other relevant option.
If your business doesn’t already have a Facebook page, that’s an important place to start too. There’s simply no reason not to. Reconsider the above stats and then the fact that a business page on a website with that kind of following is free. That page can provide all kinds of exposure that leads to sales.
Make sure your Facebook page has a form tab too. This way, potential customers have a means of providing you with sensitive information without it being seen by the rest of the world.
Once you have a Facebook business page up and running, you can really start driving home the leads. Offering promotions may be the best way to do this. Just be sure that your Facebook promotion tab only provides the offer to those who share it on their own friends. You can also ensure that entrants are only considered if they share their contact info with you (let them know beforehand that you intend on using it for business purposes though).
Lastly, don’t be afraid to use your Facebook page to show a softer side every now and then. People aren’t logging onto Facebook for business purposes, though it can certainly happen. So it’s ok to lighten up every now and then and share something funny, interesting or useful with your audience.
