Build trust before asking for the sale
Posting anything you like on your blog will not get you anywhere. You need a content strategy in place that does three things: aligns with your marketing goals, resonates with your target market and gets in front of your audience. When this type of strategy is successfully implemented, your audience will start coming to you. You will begin building a significantly better relationship with them than if you were shoving ads in their face. The end result should be a consistent generation of loyal customers. That is, if you are doing it right.
