thanks for the insight!
Provide value without expecting value in return. If you look on [/r/entrepreneur](www.reddit.com/r/entrepreneur), you can see some posts where people use their blog posts as a reddit post, which provides value for those who don't read their specific blog. Then, you can link back to your own blog at the end of the post. In doing so, you provide value before you promote yourself, and so any products or services you then promote will be associated with quality to your readerbase.
