Here is how it affects things: --- ### 1. **Mobile traffic is more than half** Most users visit from phones. If a site displays poorly, they leave. The bounce rate rises, and ranking drops. --- ### 2. **Mobile-first indexing** Google indexes and ranks sites **based on the mobile version**, not the desktop version. If the mobile version is broken or incomplete, you lose positions. --- ### 3. **Loading speed on mobile** Responsive design lets you **load only the elements you need**, avoiding extra weight and complex styles. This affects LCP, FID, and other Core Web Vitals, that is, direct SEO metrics. --- ### 4. **One URL, one index** With responsive markup, you have the same page for all devices. This is convenient for search engines: there is no need to handle duplicates, redirects, or alternate versions. --- ### 5. **Behavioral signals** When a site is easy to use on any screen, people stay longer, click more often, and return more willingly. This improves behavioral metrics, and the search engine sees it. --- In short: **responsiveness is not just a convenience, it is already a requirement.** Without it, a site is considered outdated both for people and for algorithms.For the reviewerNote to the moderator (optional)Visible only to the moderator.
