Design and UX

What decides a website before any code exists: purpose and audience, layout, wireframe, mockup, and how to judge a design an agency has shown you. The articles explain the difference between UX and UI, how a landing page is built and how the trade changes what a small business site needs. The second half is about online shops: site search and filters, the product page, the basket and checkout — the places where shoppers give up, with Swiss data where it exists. There is also how much traffic really comes from phones and three mobile tests you can run yourself, who the WCAG accessibility requirements actually apply to, and why a fix made on the sketch costs a fraction of the same fix in finished code. The articles also check the numbers: where the “9,400% return on UX investment” that circulates in proposals really comes from, and what a conversion rate does and does not tell you. For ready-made options: how to choose a WordPress theme so you are not rebuilding the site a year later, and when a shop template is enough and when a custom design is worth it. For apps: what the client decides at each of the six stages. For businesses before a website or shop project, and for those assessing a finished design. Start with website design or where online shops lose customers.
