The idea behind ‘like’ marketing is simple. Take your business online; more specifically take your business socially networked online. Build fan pages. Have your fans following you and experiment with your posts till you start getting good number of likes.
The more the likes, the better you are doing.
When someone likes your product, that like is immediately reflected on the person’s page. It is available for all of his contacts to see. Through this publicity, his contacts are now exposed to your product, and through his recommendation, will be more inclined to click it and take a closer look.
Instead of paying a linkbuilding company to drop your link all over the Web, all you need to get Facebook likes is to establish a page for your product or service. You can easily do that for free. Besides, since people don’t get anything for liking your product, as Facebook is free, then other people are more inclined to believe that they really do support and recommend your product.
