The basic strategy is this: Post interesting content consistently with relevant hashtags. Use a service like Hashtagify for hashtag ideas. Follow users in your niche and engage with their posts. I also know a couple of people who grew their Instagram accounts quickly solely depending on shoutouts from influencers. You can use a service like ShoutCart for that or contact influencers directly (most of them list their email addresses in their bios).
As you probably guessed, the scale of strategies behind promoting Clickbank products is much larger than the ClickBank itself. One thing you must understand is the fact that you need to choose your strategy based on the product, not what you know. Every product has a different audience and every audience requires a different approach, that’s why if you want to become a super affiliate on Clickbank, you need to learn these different strategies and choose the right one based on what you promote.
