I agree with all the points you have mentioned. Talking about zero upsells, for instance, the best thing online, is setting aside a budget, and being able to respect that budget without exploding it. This is the amazing part about Wealthy Affiliate. You can plan 2,3,or even 4 years in advance and that budget will still be very relevant and applicable.
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).
This book is written by a hugely successful Amazon affiliate member, Armaan Kohli, and includes real case studies of how he’s built a successful niche site empire that’s monetized through the Amazon Associates Program. He shows you screenshots of how his income keeps growing along with an example of how he ultimately sold his 6 month old Amazon affiliate website for over $15000!
Wealthy Affiliate is also very strict on spam, which in the end is a GOOD thing, but I have to be careful sometimes about promoting my sites or referencing them. Sometimes I do have valuable information on my site that I think could help people during live chat sessions or Q&A’s, but I don’t share because I don’t want it to look like I’m spamming. They do allow people to promote their sites in certain areas, but in order to keep the community from filling up with self-promotion spam, there are times when it is best not to share certain information from outside sources, especially my own sites.
