Over the years I have linked to many books from this blog, usually to an Amazon page with an affilliate link. In the early days (2003-2004) of such affilliate links I made 70 USD at one time, and then nothing. Over time linking to Amazon, links that included a tracking pixel for years, became less helpful for readers to find books, and more helpful for Amazon to track readers.
I stopped linking to Amazon last year April, but this blog still held the links I previously made. When I deleted my Amazon affilliate account they gave me a gift card with the outstanding balance: 35 cents. They still got their tracking on the links I used here though, so those links needed to go. Removing such links isn’t much work, but I wanted to maintain the usefulness of my postings, by linking to an author’s homepages, Wikipedia entries, as well as to the publisher’s page, Wikipedia page, Internet Archive or Open Library page for their books. That work does cost time, and is now finished. I no longer link to Amazon on this blog anywhere (nor Amazon’s Goodreads), and no Amazon tracking pixels remain.
I do still buy e-books from Amazon, although that too is ever so slowly shifting to other sources (directly from publishers for instance). It’s just that I no longer send any website visitor’s data their way as well.
