Link-building from a very grassroots perspective does not happen in a vacuum. You have to give in order to get. Begin to follow certain bloggers and social media pages, and make sure you engage in discussions in a meaningful way. Don’t just “like” a few images and think you’ve made an impact. Sincerity is the name of this game, and it will be worth your time to be thoughtful and honest. Put a real face on your company, and watch as others become attached to the genuine way you’ve positioned yourself.
