If you have a blog with an engaged readership, you know how great success can feel. Your fans get excited, they comment, they click! The end result is you feeling great about your content. However, when you're partnering with a brand, there's a lot more on the line. You have to consider meeting the brand's measurements and hitting its goals. If your blog post doesn't perform the way you expected, don't get discouraged. Instead, take this as a learning opportunity.
