Even if you’re in a super-tight niche, you probably write blog posts about more than one subtopic in your niche. For example, maybe some of your posts are about deep sea fishing in the Pacific and some are about deep sea fishing in the Atlantic. Or maybe some posts are about knitting with wool and some are about knitting with acrylics. No matter what the topics are, you can offer one lead magnet for each of them. Some marketers have doubled their opt-in rate with this technique.
What many affiliate marketers do is find their niche in the market. This allows them to be focused on specific products or merchants, which lets them gain loyal followers and build a reputation that reflects expertise on a particular subject. After all, you as a consumer will most likely take the word of a person who has reviewed all kinds of vehicles as opposed to someone who reviews everything from sports cars to lemonade to fertilizer.
