MemberPress is a feature-rich plugin that will enable you to turn your WordPress blog into a fully functional membership site. Depending on how you want to run your membership site, you could have a mixture of free and premium membership plans. Premium plans could include no adverts, free downloads, access to extra content, membership forums, and much more. However, it is important to remember that if people are going to pay to view your content then it must be high quality. Otherwise your members won’t renew their subscriptions when the time comes.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
