What you will get

A wide black banner with glowing neon accents, a large BLACK FRIDAY headline, an “Up to” discount line, floating shapes of your product type and a clear area on the right where your button will sit.

Common mistake

The headline or the discount number is misspelt or garbled.

Fix: Replace [PERCENT] with a real number such as 40 and read every letter. If anything is wrong, regenerate without text and add the words in an editor.

Also watch for

The picture is not as wide as 16:5, or the tool changes its shape. Midjourney follows --ar 16:5. In other tools crop or extend the picture, and keep the headline on the left so the crop cannot cut it.
The space for the button is filled with shapes, or the floating products look nothing like yours. Say “the right 30 percent is plain black” and use generic shapes. Put your real product photos and a real button in your website or editor.

Try a variation: Cyber Monday

Change the headline to “CYBER MONDAY”, the neon to electric blue, and add faint circuit lines in the background. It reuses the layout for the following sale.

Still not right? Reply with this

Keep the style. Leave the right 30 percent plain black, make the headline spelt exactly BLACK FRIDAY and show the discount as 40 percent with no other text.
