Let’s say you have a promotions page where you’re promoting a product via affiliate links. If you currently get 5,000 visits/month at a 2% conversion rate, you have 100 referrals. To get to 200 referrals, you can either focus on getting 5,000 more visitors, or simply increasing the conversion rate to 4%. Which sounds easier? Instead of spending months building domain authority with blogging and guest posts to get more organic traffic, you just have to increase the conversion rate by 2%. This can include landing page optimization, testing your calls-to-action, and having a conversion rate optimization strategy in place. By testing and optimizing your site, you’ll get far better results with much less effort. 
I would also like to see a forum built into the platform. Wealthy Affiliate has a unique way of building a community and I understand why they shy away from a standard forum type of format. Instead, they want to promote live chat sessions, blog posts, private messaging, and public questions where people can comment below. This type of setup is pretty cool at times, but I also do enjoy forums where I can just browse by topic.
