Don't take content from the internet and copy and paste it for the exclusive purpose of creating a WA blog. Write using your own words on the WA blogs.
Now, one of the things I see sometimes on WA blogs, which is perfectly fine and I have done it myself, is when you take a screenshot of your Google Analytics or from your expense worksheet from Amazon or one of your other Affiliate partnerships, showing your progress and how much money you are making and/or how much traffic you are getting. That is fine, because you are blogging about your progress and showing everyone that success is possible using the WA training. You are providing encouragement and inspiration and that is encouraged, because it is easy to become discouraged and if you are a new member, you might be wondering if this is another scam. So, showing your success with screenshots is fine.
