I have set up links to books on Amazon; using the same process to cut and paste the link into the "link" box area. All of the targets are set to Default on all links.
Issue: When you click on the link for one book, it will return to my website if someone hits the back button. For other links it won't....it simply sits there at the page on Amazon.

I would like it always to return to my website if they hit the back button or if they closeout (X) from Amazon. How do I accomplish this?

Got a link to the site?

There should be no issue with going back to your site if the visitor doesn't click multiple items in Amazons site first. I would highly suggest that you add a _blank to your target setting of the links to keep them from leaving your site all together and that way when they close Amazon they will still have a window or tab with your site open and that "should" be the site that is then gone right back to as long as they have not altered their browser settings to do something different.

Other than that we'd need a link to see how you have it setup at the moment. :)

Thank you. The information you provided was very helpful. It took care of the issue 100%

Glad it helped and good luck with your site!
