How Do I Quickly Resize My Book Cover
Most ebook aggregators require a book cover of at least 1600 x 2400 pixels. If your cover file is a different size, here’s how to resize it using tools you likely already have — no downloads needed.
Goodreads
Goodreads is one of the largest concentrations of active readers online, and — since it’s owned by Amazon — activity there can feed directly into your book’s broader discoverability.
Smashwords Uploading Errors
One of the most common errors when uploading to Smashwords is a corrupted image — and it’s usually not actually corrupted, just mislabeled.
Selecting The Correct Niche Topic For Your Book
Writing a book is a real investment of time — it’s worth spending an hour on research before you spend months on the manuscript. The good news is you don’t need to guess: Amazon itself gives you the data to check whether a niche can actually support a new book, before you write a single chapter. Here are the six numbers worth checking.
What Is A PDF File?
PDF (Portable Document Format) is a file format that preserves a document’s exact layout — fonts, images, spacing, page breaks — so it looks identical no matter what device, operating system, or software opens it. That’s the entire point of the format: what you see is exactly what everyone else sees.
Creating A Website For Your eBook
Once your book is published, a website gives readers one place to find everything about you and your work — something no retailer page can offer. You have two realistic paths to get there.

Selling Your eBooks On XinXii
XinXii is a Berlin-based self-publishing and distribution platform that lets independent authors sell eBooks and audiobooks directly through their own XinXii author page, with optional distribution to major retailers like Amazon, Kobo, Apple Books, and Casa del Libro.
Selling Your eBooks On Smashwords
Smashwords remains one of the largest independent ebook storefronts, but the way you get your book there has changed. As of 2026, you no longer publish directly through Smashwords — instead, you publish through Draft2Digital, which now owns and operates Smashwords, and select the Smashwords store as one of your distribution destinations.
Useful Links For Advertising Your eBooks
Beyond the major retailers, there’s a whole ecosystem of ebook deal blogs and reader communities that will feature your book — some for free, some for a fee. Reaching out directly to the sites below is a low-cost way to get in front of readers actively looking for their next book.
