I'll start with facebook as out of all social media platforms this is the one that I get more referrals from and more visits to my websites.
What is the best strategy for facebook?
As You can see from the image above we have 1.86 billion users to target.As a guide Facebook is ideal to build Brand loyalty by using the facilities available such as Groups and pages where you can build a fanbase/customer base via relationship biulding and engagement.
Be careful not to over advertise in the various Facebook selling groups or networking groups or you could get banned especially if you use URL shorteners. I advise posting in 10-15 groups per day once in the morning and once in the evening and avoid posting in the same group twice in 24hrs.
If you follow the rules you can get good results. The downside is how many people you can reach per post especially in a page post where I believe it does not go to all of your members.
You can boost and target your audience if you wish to pay.
What is your opinion as far as FB goes, a business page, or do you use your personal account?
