What works on Facebook and what doesn't

Hi

I recently went to a Facebook meetup in Sydney. 

Things that I learnt from this meetup and other places.

1. Don't keep posting 'buy my book'. It will turn potential customers off.
2. Start a conversation. Let people connect with you. Don't expect that your book sales will suddenly go crazy. It's more an organic approach.
3. Try Facebook Message Bot. It's fairly new and not too crowded yet. You can set this up to funnel your prospective customers to your product.
4. Post videos which hint at what you do.  
5. Post offers of free stuff or a competition.
6. Always remember Facebook is like the old fashioned town square. People meet people and have coffee and discuss the things that interest them.
