Even for those authors who have already created their website, the information on AWG is great for refining your skills, whether it’s keeping your reader’s attention or where to spot great examples of other authors’ websites.
It’s hosted by a business acquaintance of mine who also is a talented book cover designer. All the covers for my books published under my real name (and not a pen name) feature his work. You can also check out his book covers here and his premades here.
At any rate, feel free to check out the Author Website Guide and continue coming back for more info.
