DESIGN
Everyone Can Tell
Your Site Was
Built by
AI.
It takes about five seconds. There is a
fingerprint, and once you know it you cannot
stop seeing it.
SAME FONT
SAME GRADIENT
SAME THREE CARDS
// WHY THIS COSTS YOU
A site that looks generated looks like nobody spent anything
on it. That is the read a buyer makes before they read a
word.

THE FINGERPRINT
Four Tells, Every Time
01
The Inter typeface
Not wrong. Just the safest possible answer, chosen by
default a million times over.
02
An indigo to purple gradient
The single most recognisable signature of the lot.
03
Three rounded cards in a row
Usually with a small icon on top of each one.
04
A hero that fits any company
Swap the logo and the copy still works. That is the
problem.

WHY IT HAPPENS
It Is Not Bad Taste. It Is
the Average.
A model answers with the middle of
everything it has seen. The middle of web
design since 2019 is a specific purple.
// THE DETAIL THAT EXPLAINS IT
That colour is the default in the most popular styling
framework on the web. The person who chose it has
publicly apologised for it.
So the model is not making a choice. It is declining to make one, and
nobody told it otherwise.

THE FIX THAT DOES NOT WORK
Stop Asking It to Make It
Nicer
"Make it look better"
You are asking the thing with average taste to apply taste.
You get a different average.
Decide before it builds
Fonts, colours, spacing, settled up front and handed over
as a rule, not a request.
Same model, same brief, one extra file. The difference is not subtle.

THE DESIGN FILE
What Actually Goes In
It
Type: two fonts. One for headings,
one for everything else.
Colour: your background, your text,
one accent. Not a palette of nine.
Spacing: the gap between things,
picked once and reused.
// and the one people skip
Never: the things it must not do.
Written once. Handed to it before a single line gets built, every time after
that.

IF YOU ARE NOT A DESIGNER
Borrow the Decisions
Find three sites you like
In any industry. Liking them is the only qualification you
need.
Name what they share
Lots of white space? Big type? One colour used
sparingly? Write that down.
Turn it into the rules
That list, written as instructions, is your design file. It does
not need to be clever.
You are not being asked to invent a style. You are being asked to pick one,
so the machine stops picking for you.

THE HONEST BIT
This Does Not Make You a
Designer
It removes the tell
Your site stops announcing how it was made. That is worth
doing and it is not the same as good design.
Taste is still the input
The file only carries decisions you already made. Nothing
in this replaces having a point of view.
// WORTH CHECKING TONIGHT
Open your own site. Inter, a purple gradient, three cards in a
row? You are not looking at your brand. You are looking at the default.
