4. Tier 2 content (content that is keyword rich and relevant to your niche. Doesn’t have to be all that readable, it just has to be indexable by a search engine.)– Here put same options as with the Tier 1 content situation with the only difference that you set the 1st input to “Regular.” It is important that lower tiers have a lower quality of content compared to upper tiers.
Notice: Because of the 3 days free trial, we must use Paypal's subscription button even for a one-time price. Unfortunately Paypal has a bug that only allows you to set max 5 years for the subscription. So when you see Paypal's notice that your one-time fee is actually a subscription that will be renewed in 5 years, in fact it is not true, it is a one-time forever payment, NOT renewable after 5 years.

Quality readable content is key here. Google, for example, will recognize that people are leaving your site soon after arriving if they perceive that your site or blog is full of junk content. This is called "bounce rate." If your bounce rate is high, then people are quickly leaving your site. But for the sake of your business, to build your online reputation and brand, you want people to visit your site, stay for a while, and then keep revisiting over the long term.
