How to use Google Plus to promote your content
Write an article on your website and then post a link to it on Google Plus. Post a big picture and some intro text as well.
Use hash tags in the text to make it more searchable on G+.
Statistics is important. But don't spend too much time on it. It can be misleading and can distract you from doing things that matter.
Having a complete G+ profile with a nice picture is very important to your success.
80% - 20% rule
80% of your G+ posts can contain links to content from other people. 20% will link to the content that you created.
