Facebook can be a great tool for businesses that are looking to engage with or attract customers. Not only do you want to promote your Facebook page within Facebook but also externally on your website, business cards and sign writing for example.
Your Facebook Page is the first thing people see when they come to visit you on Facebook. Let visitors know why they should like you. Make sure that your description or welcoming paragraph sums up what you do but in an interesting way. Make sure that you have the correct tabs within your page and if you are selling a product or service, then have a section dedicated for photos. Categorize these photos if possible, to allow the views to go straight to the ones they are interested in.
When your page first goes live, be sure to ask as many friends and family members to like it. Then when new people come on to your page it already looks like you are popular and they are more likely to want to like / follow you too.
Facebook ads are another great way to increase Facebook likes. Experiment with different types of ads to see which ones work best for you and give you the best return on investment.
