We scroll past more images in a day than our grandparents saw in a year. In that flood, a good visual isn't decoration - it's how you get someone to actually stop. But "add more images" is terrible advice. The wrong visual costs you more than none at all.
Why visuals pull people in
The brain reads an image faster than it reads a sentence - that's just how we're wired. You'll see stats thrown around (images get more views, retention jumps, all that) and directionally they're true. But I'd rather you remember the principle than the percentage: a relevant visual lowers the effort of understanding you, and lower effort means people stay.
The kinds that actually earn their place
- Real photography. Authentic beats stock every single time. Real people, real work, real spaces - that's what builds trust. A polished stock photo often does the opposite.
- Custom illustration. This is where you get differentiation photography can't touch. A consistent illustration style makes a brand instantly recognizable.
- Data visualization. A clean chart makes complex stuff digestible - and people share a good infographic far more than a wall of text.
- Video and motion. A short explainer can lift conversions a lot, and subtle micro-animations guide attention and give feedback without shouting.
The mistakes I see constantly
Using visuals as filler with no purpose. Cramming in conflicting imagery that fights itself. Low-res or obviously irrelevant stock. And forgetting alt text - which quietly breaks accessibility and SEO in one move.
The only test you need
Before any image goes on a page, ask three things: does it help the user understand? Does it fit the brand? Does it reinforce the message on this specific page? If it fails any one of them, cut it. Design is the silent ambassador of your brand - make sure yours is saying what you actually mean.
