Do you like to read books?
If you do, read a lot and after you read one book, write down 10 things you’ve learned from this book.
Then write a blog post about it and insert your Amazon affiliate link to the book.
Share the link to social media sites.
Answer questions on Quora. This is helpful to people and accelerates the process of getting traffic to your blog.
If you read 1 book per week, in a year you will have 52 posts with your affiliate links.
If you’ll write in engaging style, people will want to read your posts and perhaps buy the books through your affiliate links.
Hope this helps.
