Fortunately, Amazon provides a way to share your book’s sales page on Twitter and Facebook while using your affiliate tracking code. Go to your book’s sales page while logged into your affiliate account, then use the “share” tab at the top to post to Twitter or Facebook. Here’s a simple tutorial that walks you through the process.

Another way to get an Amazon-approved short link is to search for your book from your Associates home page. See the yellow “Get Link” button? Click the arrow next to it and choose “Shorten URL with amzn.to?”
I discovered another creative way to boost your affiliate income in a Kindle publishers’ forum. “One thing I’ve done is post product links to the equipment that I or my fictional hero use in the books. Things like knives, optics, tents and such,” said one user.
For example, he says he made an 8 percent commission on a rifle scope that costs over $2,000 — that’s more than $160 from one sale through his affiliate link!
Letting your book’s characters sell things for you is a neat trick! Unfortunately, the consensus of Kindle forum users is that it’s against the rules to include affiliate links in Kindle books. Many authors get away with it and Amazon has not fully clarified the matter, but a safer strategy might be to have “character profile” pages on your website, with affiliate links to each character’s favorite products. You could then link to those profile pages at the end of your book, or link to a “more information” page on your site.
Finally, your readers probably value your opinion, so why not have a list of your favorite books by other authors on your website or blog? Of course, you’ll link to all of their books using your Amazon Associates links.

Start your own Website or Blog at very low cost

There are two main approaches or business models to choose from when setting up an affiliate marketing site:
Resource Sites: These sites are focused on offering lots of how-to articles and posts, and then provide affiliate links or banner ads to click for more details.
Frequently adding fresh related content is vital because it gives people a reason to return to your site–and click some of your money-making links.
Review Sites: You’ve tried the products in your niche, now you write them up and rate them to help your site visitors decide what to buy. For each product you review, you provide a link or banner ad that clicks through for sales on your merchant partner’s site. Less frequent content updates are necessary–just tweak your site about once a week to let the search engines know your site’s still alive, and always try to build links.
