User experience affects SEO because search engines watch how people interact with a site. If users stay longer, move through pages easily, and find what they need, it signals that the site is useful. A clear design, readable text, and simple menus all make the experience better. When a site confuses users, they leave fast, and this hurts search rankings. Good user experience also makes your content feel more trustworthy, which helps people share it. Search engines reward pages that give comfort and clarity.
