Hi, I think this is the most comprehensive review of Wealthy Affiliate which I have seen, and I have seen many because I am a WA member. There is nothing I could add to this review except to conform what you are writing here. I started here and built 2 sites. The lessons and support from the community are as you describe, I could not manage anything without the support. Only one remark about ambassadors, they get nothing. I am one of them so I should know, right?
I am a long-time blogger and decided to join WA premium for a month. I was looking to build an affiliate site and had no experience in that area. I figured I could get through most of the premium training within the month. But the thing that I didn’t like was the way they guided you to use their system to set up your domain. No way. I want control over my domain name and WP site. That’s where people get trapped because they don’t know how to do this on their own. But the only way I would know that is having been a blogger before registering. I’ll finishe out the month. Get what I can from the training and apply to a site I start outside their “silo”.
As the years passed they moved more towards the blogging model and the concept that anyone can build a business by blogging about whatever they are most interested in. This approach is far more long-winded and very hit-and-miss in terms of how likely people are to succeed. Sure, some people will eventually find great success if their chosen topic happens to be a profitable niche and they are good at writing and stick it out for long enough. For many others it will not go beyond being a hobby site that pays a bit of spare change. No need to sign up to Wealthy Affiliate to do that. Just throw up a free blog at Blogspot.com, write about what you’re interested in, and throw in some affiliate links here and there. It’s not rocket science, folks.
NOTE: Residents of Arkansas and Louisiana – Amazon does not offer their affiliate program to residents of your state because they have insisted that Amazon collect sales tax on sales by affiliates, so Amazon pulled out of those states. So if you live in one of these states, please do not purchase this book. Amazon is working with some of these states to solve this issue, and we will note any changes in our newsletter as they occur.
So yes, you can be successful. Wealthy Affiliate will help you with every aspect of your content creation, including how to structure content, how to write in a way that converts/ranks, and they even provide you with an awesome writing platform called SiteContent that will speed up the writing process drastically and check all grammar/spelling (along with a lot more).
