One key to high conversion when promoting affiliate products is to align as much as possible the needs of your audience, with the product that you are promoting and the content being produced on your blog.

For example if my readers are all beginner digital photographers, I’m producing a blog with content that teaches basic principles of photography and I was to promote to them a book or course on beginner to intermediate photography tips - I’d have a pretty good chance of generating some sales and therefore commissions.

However if I was to promote the same course here on ProBlogger the campaign would fall on it’s face and I’d probably do my reputation more harm than good.
