Some very good advice from master editor and book promoter Dr Euan Mitchell re. ebooks (and print versions for some of the items)
a. Include your website's address as a clickable link.
b. Include the covers, blurbs and shout-lines for your other novels.
c. As part of intriguing your readers with blurbs, etc, also include clickable links to FREE SAMPLES of your other novels. (Kindle offers the first 10-20% of any novel as a free sample to any reader.)
d. Include clickable links to your socials.
e. Encourage readers to review your novel on Amazon and actually explain why it's so important.
f. Acknowledgments. This is more about your behind-the-scenes story that readers can really connect with, rather than a list of names that don't mean much to most readers.
g. Include a clickable link to your pages on Goodreads, the world's biggest book discussion/review forum.
