The ones that cost you visitors.
TEXT TOO SMALL OR TOO LIGHT
Grey text on white, at fourteen pixels, is genuinely hard to read. This is widespread and easily fixed.
NO CLEAR NEXT STEP
Pages that inform and ask nothing.
HIDDEN CONTACT DETAILS
A phone number only on the contact page, or only in an image.
AUTOPLAYING VIDEO OR AUDIO
Irritating, and on mobile data, expensive for the visitor.
SLIDERS
They change before anyone reads them, add weight, and most visitors never see past the first slide.
POP-UPS ON ARRIVAL
Asking for an email address before the visitor knows what you do.
STOCK PHOTOGRAPHS OF PEOPLE
Recognised instantly, and they reduce trust.
TOO MANY FONTS AND COLOURS
Looks disorganised and slows the page.
CLEVER NAVIGATION LABELS
"Solutions" and "Connect" instead of "Services" and "Contact".
ENORMOUS IMAGES
The most common cause of a slow site.
CONTENT THAT NEVER CHANGES
A footer copyright date from three years ago signals a business that may not exist.
