You can not use the author or publishers past results, illustrations or screen shots of earnings as any indication of what you will earn or to offer assurance that you will achieve the same in future.
The money you make and income achieved is based on multiple factors, we do not know you, your business ethics, how serious or motivated you are and whether you are prepared to do what is necessary to get started, so can't comment on what you will earn or achieve from mini Blogs.
For this reason the author/promoter does not guarantee or imply that you will make a load of cash, get rich, do as well as himself or achieve any income that is illustrated in the examples or even make any money at all, your reading this course confirms you accept and understand the above.
