Loading speed (Page Load Time) The faster a page opens, the less irritation and the higher the engagement. Critical for the first 3 seconds. ## 2. Time to Interactive What matters is not only when the site "appears", but when it can actually be used (buttons, forms work). If it looks nice but is not clickable, UX suffers. ## 3. Core Web Vitals (per Google) - **LCP (Largest Contentful Paint)**: how fast the main visible block loads - **FID (First Input Delay)**: the delay before the first response to a click - **CLS (Cumulative Layout Shift)**: how much everything jumps around during loading ## 4. Responsiveness and mobile version UX breaks if a phone user has to scroll sideways, zoom the font, or close banners. ## 5. Ease of navigation Clear structure, logical flow between pages, uncluttered menus, understandable buttons. ## 6. Visual hierarchy The user should immediately understand what matters, what is clickable, and where to look. ## 7. Accessibility How easy it is for people with limitations to use the site (contrast, alt text, keyboard control). ## 8. Cognitive load If a site requires thinking, searching, or guessing, that is bad UX. ## 9. Interface reliability No bugs, freezes, or sudden data loss, the basis of basic trust. ## 10. Personalization / content relevance UX improves when the interface and information adapt to the user. --- **Summary:** UX is not about being "beautiful", it's about being "clear, fast, convenient, and stable". Anything that gets in the way of these four qualities makes the experience worse.For the reviewerNote to the moderator (optional)Visible only to the moderator. Helps review go faster.
