Before judging a website by the homepage, try to do something on it. Find a product detail. Compare two services. Send an enquiry from your phone.
It's quite possible to admire the design and get annoyed with the website in the same visit.
The work needs to hold up once somebody stops looking at it and starts using it. That's where I would judge whether the design is helping the business.
Help people understand what they have found
The first job is orientation. What does this business do? Who is it relevant to? What is available here?
A dramatic opening line can have character without withholding the basics. Give it a supporting sentence that explains the offer. Show the work or product early enough to make the claim concrete.
“Discover a world of possibilities” could introduce nearly anything. A useful page should sound as though it belongs to this business.
Make the evidence easy to reach
People evaluating a service may need examples, process, scope or evidence of competence. Someone buying a product may need dimensions, compatibility, delivery information or a closer view of the material.
Place the answers near the questions they resolve. Do not make the visitor travel through the site's entire navigation to discover whether the basic offer fits.
Take a consultancy offering two levels of support. The visitor needs to know what is included, who each option suits and what happens after an enquiry. Two elegant cards labelled “Essential” and “Exceptional” don't tell them any of that. The layout needs useful distinctions to work with.
A testimonial is useful when its origin and relevance are clear. A row of anonymous praise says less than one specific account of the work.
Create hierarchy without hiding substance
Typography, spacing, contrast and layout help establish the order in which information is encountered. That is not an argument for reducing every page to three slogans.
Use headings that describe the content. Keep supporting copy readable. Let people scan for the part that matters and then read it properly.
Some decisions need detail. The design should make that detail manageable, not remove it to preserve an empty aesthetic.
Make the interaction dependable
Can someone use the navigation with a keyboard? Can they tell which field needs correction? Is the confirmation meaningful? Does the page remain usable when the text is enlarged?
Accessibility concerns whether people, including people with disabilities, can perceive, understand and operate the site. Keyboard access, readable content and controls that make sense are part of the design, not an optional tidy-up afterwards.1
Build those checks into the work. By launch day, you want to be confirming that people can use the site, not discovering that the menu has never worked from a keyboard.
Give the site the character of the business
A practical company should not become generic simply because it needs a usable website. A confident brand should not become exhausting because somebody mistook personality for constant movement.
Use the identity deliberately. Let colour, imagery, language and interaction support the same character. Keep the business recognisable from the first page to the ordinary confirmation email.
Keep the navigation, headings and controls familiar from page to page. There’s plenty of room for character without making visitors work out a new set of rules every time they click.
Judge performance in context
Loading, responsiveness and layout stability deserve attention. Google's page-experience guidance considers those alongside the quality and usefulness of the page.2
Look at real tasks as well as scores. Can a customer find the right product, understand the proposal or submit an enquiry successfully? After submission, do they know it arrived and what happens next?
Ask someone who doesn't already know the business to choose the right service and explain their choice. Listen to where they hesitate. Those gaps deserve as much design attention as the opening animation.
