If you create an expectation of content on your blog, readers return expecting to find similar content. If you switch one week from blogging about grooming pets to blogging about grooming horses, you have set an expectation that your blog is about grooming animals. If you switch from grooming dogs to racing cars, readers are thrown off and their expectations aren’t met. The odds are they will not return for more.
It used to be said that predictability was boring. In blogging, predictability builds return customers. They know you are the expert on this subject and that you are the source for information. Meet their expectations when they return.
