Kindle books can make you quite a bit of money, just from the royalties. But that's barely scratching the surface. If you play your cards right, you can make a whole lot more from your Kindle books.

How do you do that? By using your Kindle books strategically.

1) Get the contact information of your buyers

That's easier said than done. If you sell books online yourself, your shopping cart system usually captures the contact information for you and adds it right into your autoresponder, such as Aweber or Constant Contact.

Amazon is pretty stingy with giving out customer contact information, so it can be tough to get your buyers' info.

But all is not lost. In fact, your Kindle book gives you a perfect opportunity for capturing your customers' information. Here's how:

2) Add lots of links to your Kindle

At the bare minimum, there should be a link back to your website prominently displayed in your book. It could be in the footer or in the resource section, or you could create a short chapter that will offer an enticing gift or upsell that will get the reader to your website.

You could even include an full-page ad or advertorial on one of the first pages.

And speaking of the resource section of your book... that section could contain a number of links, some of them to your website or sales pages, some of them to your blog, and some of them potentially to affiliate products.

However, be sure to make one of your most enticing offers one that lets you capture your readers' information. That's the most important part of the game. Once they're on your list, you can always sell them more of your products.

3) What should you offer?

You should create an offer that is complementary to what you wrote about in the book. In fact, while the book should offer real information, it should also leave the reader wanting... more. And you promise your readers that "more" in a follow-up offer.

For example, if you have written a short book on stress management, you could offer a downloadable hypnosis audio as a free gift. Such an audio offers real value, is an extension of the original offer, and chances are that most people who discover it in the book will sign up to get it. And that's exactly what you want.

4) Create an enticing upsell on your Thank You Page

After they go to your free offer and sign up, make sure there's an enticing upsell or affiliate offer on your Thank You Page. While not everyone will click, you might get a pleasant surprise.

5) Send follow-up emails

Last but not least, once you have captured your prospects' email addresses, use them, and do so wisely.

You should focus on three things: build a relationship with your readers, provide more value, and finally... nudge them to purchase something else.

And if you do the things in this article, you'll soon have a growing list - and many of the members of that list can easily be turned into happy repeat buyers.
