The more traffic you have, the more money you can make with ClickBank. In order to maximize your traffic, you should spend some time identifying commonly searched keywords that relate to the product you plan to sell. If you create articles and other content based on those keywords you can often get some traffic from search engines, especially if you target the less competitive long-tail keywords in your niche.
If you are not comfortable in penning down your thoughts through blogs and content writing, make use of your camera to create a video presentation. Create your YouTube channel, upload videos and start monetising them. Choose a category or subject that you want to make videos on and get started, but make sure it's a topic that will interest a lot of people. Everything from cooking shows to political debates can find many takers on YouTube. You have to create a YouTube channel, which works on a similar model as a blog. As you make your channel popular and the number of subscribers grows, so will your earning potential. The payment one gets is based on every thousand views.
If you have experience with marketing, SEO, or a knack for getting people excited about the products and services you use on a regular basis, think about refining your skills and putting them to work making money online as a small business marketing consultant in your region—especially if you can become a local SEO expert and can help local clients rank higher in their search results.
If you have pop-ups and optins on every page, I would have to think that it would be a lot harder to convince someone to link to it. Especially since the pages where you have your optins (and probably receive the most traffic) are probably the same pages that you have your best content on as well that you'd be hoping to pitch in your outreach campaign.
