Hi Nestor, I am SO sorry I missed this post, @nessware Hopefully it’s not too late for you to prepare your talk.

Here are my thoughts on these questions:
1.  I’m not sure exactly what you mean by this.  Are you talking about how can businesses participate on Facebook?  I think in that case things that businesses can do are:  Start a Page to communicate with customers, Offer coupons and discounts, Use tabs to have people sign up for their newsletter, Run a Facebook ad, and I don’t have a concrete 5th one.  

2.  There are a lot of good posts about this.  Here is one I like from Lisa Barone:  http://www.businessinsider.com/6-things-not-to-do-on-facebook-as-a-brand-2011-2I would also add to this some of these things:

• Deleting negative comments (unless they are extreme)
• Selling too much and not adding value for your customers
• Being boring – I know this was listed, but I feel like it’s a big one
• Only talking about yourself – not encouraging conversation
• Violating Facebook rules – this one happens a lot when people run a Facebook contest with people saying, “like this post to enter” or something like that.

3.  This is a great article from Mari Smith on this:  http://www.marismith.com/reasons-use-facebook-for-business/  (I had problems seeing the article on Google Chrome but Firefox worked)  

4.  This is a broad question.  There are a lot of good tips out there.  This is one we have on Social Media Examiner:  http://www.socialmediaexaminer.com/5-tips-for-moving-social-media-leads-into-the-sales-funnel/We also have a lot of posts more directed at social media in general:  http://www.socialmediaexaminer.com/tag/social-media-leads/  

I hope that helps!  Anyone else have any good tips?

@andrea-vahl Amazing as usual!!
