It is important to have a blog network of your niche. Having a good relationship with bloggers and site owners will give you more chance of linking and recommending you on their sites. This means more chances for you to sell your products or services.
Building a relationship on your blog network should be about finding win-win relationships. Before you ask help from them, you need to help them with your initiative.
