I think making your content as clear as possible to the reader will get you more conversions. Make everything clean and simple, have a catchy title, a clear value proposition and make it as easy as possible to convert.
Other than that I think simplest and quickest way to improve conversions is to add a call to action, i.e. tell them what you want your readers to do and make it as easy as possible for them to do it. You can see this done especially well in YouTube videos, almost all videos on YouTube will tell you to like, subscribe, hit the bell icon etc.
