I'm just starting at Clickbank, so I'm a total newbie, but if I want to follow this strategy can I do it promoting just one product, for example, Category>Health & Fitness ---> X product. Then, should i start a blog or something like that where i can talk about things related to the product subject? if so, do i have to start making entries about this recurrently? or I can opt for just making an article with a free ebook in exchange to user's e-mails and follow the process?
If you’re a blogger, start by going through your analytics and finding your most popular posts. In Google Analytics (GA) you can find these pages by going to your GA Dashboard > Behavior > Site Content > All Pages. Examine the ones at the top of the list that bring in the most traffic. Are there any affiliate products or services you can naturally include in them?

22. Advertising – This is definitely the most old-school way of earning money with a blog. It’s also starting to become the least common way. You can sell advertising spots directly on your site or you can sign up with a company like Google AdSense or Media.net. Either way, you won’t see a whole lot of money from ads until your views are well into the thousands each day.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent.

Clickbank is a market platform for vendors (product creators) to sell their digital products. Such products could range from ebooks, downloadable resources/programs or online membership sites. On the flip side, it’s also a place that widely attracts affiliate marketers to help these creators sell their products, essentially giving them a source of free publicity and advertising in exchange for a commission fee on every sale.
