Mistakes that mark a book as self-published
"Looks self-published" is a real perception and a costly one, and it doesn't come from readers analyzing your design. It comes from a small set of recurring errors that professional covers simply don't contain.
The good news is that the list is short, specific, and every item on it is fixable.
1. The title is too small
The most common and most expensive. It looks elegant at full size and vanishes at the size that decides sales. Professional covers routinely run type far larger than feels comfortable while you're zoomed in.
Fix: run the thumbnail test, then make it bigger than you think is reasonable.
2. Too many things
The lighthouse and the girl and the storm and the locket. Clutter reads as amateur because it's the visible evidence that nobody chose. One subject. Composition and negative space →
3. Type dropped onto finished artwork
The signature of a cover assembled rather than designed: the title floats over busy detail, outlined or drop-shadowed into semi-legibility, sitting wherever there happened to be a gap.
Fix: reserve a calm area for the title from the start. If the art is already made and there's nowhere for type, regenerate rather than rescue.
4. Giveaway typefaces
Papyrus, Comic Sans, Curlz, Bleeding Cowboys. Trajan is the subtler version — it was the film-poster face for twenty years and now reads as dated rather than epic. Three or more typefaces on one cover is its own tell. Typography and hierarchy →
5. Wrong genre signals
A cover can be well made and still fail if it's speaking the wrong language — a literary-abstract treatment on a cozy mystery, a bright rom-com palette on a grim thriller. This one is invisible to the author, because you know what your book is. Readers don't.
Fix: look at the top 20 covers in your actual sub-category and ask whether yours belongs on that shelf.
6. Low value contrast
Pale type on a pale sky. If the title disappears when you desaturate the image, it will disappear in a search result too. Color and contrast →
7. Stretched or upscaled artwork
Distorted proportions from forcing an image to fit, or the mushy, soft-edged look of a small image blown up to print size. Print is unforgiving: 300 DPI at final size, or it shows. See What resolution should my cover artwork be?
8. Author's name bigger than it's earned
Until your name sells more copies than your premise, the title leads. An unknown name set larger than the title spends your best space on your weakest asset.
9. The AI tells
Increasingly the fastest way to look amateur, because readers have learned the signs — and there's currently a visible move toward handmade texture, visible brushwork and imperfect lettering precisely as a reaction against the machine-made look.
Watch for hands (still the classic failure), faces that are subtly uncanny or unnaturally symmetrical, that over-rendered glossy sheen where everything is equally lit and equally sharp, malformed text in the artwork, and dead-center symmetrical compositions with no room for type.
None of this means don't use AI. It means don't ship the first result: crop, recompose, reduce the palette, and choose art with texture over art with polish.
10. Ignoring the edges
Titles and faces sliced by the trim, or a thin white line down one side where the artwork didn't bleed. Every printer trims with a tolerance, so anything within about ¼ inch of an edge is at risk. Trim, bleed and safe area →
11. A spine that doesn't match
The most-missed part of a print cover, because you never see it while designing the front. Spine color that doesn't continue the front, text too big for the width, or a title crammed against the folds. The spine is what browsers see on a shelf — it deserves the same attention as the front.
12. No physical proof
Ordering one copy before you announce the book catches everything a screen hides: colors darker than expected, a spine slightly off, type tighter in the hand than it looked. It costs the price of one book.
In the Cover Maker. Six of the twelve above are checks the tool runs for you: the thumbnail and grayscale test, the DPI warning, live trim and bleed guides, spine width from your real page count and printer, and a barcode block placed to your printer's own spec.

The short version
If you do nothing else: make the title bigger, remove one element, and check it at thumbnail size. Those three account for most of the distance between a cover that looks self-published and one that doesn't.
