## It's Not Just About Keywords You can build the most beautiful React application in the world, but if Google's bots can't parse it, nobody will find it. Technical SEO is the foundation upon which content ranks. ### 1. Semantic HTML Stop using `<div>` for everything. * Use `<header>` for navigation. * Use `<main>` for the primary content. * Use `<article>` for blog posts. * Use `<h1>` through `<h6>` hierarchically. This helps screen readers and search bots understand the structure and importance of your content. ### 2. Core Web Vitals Google now ranks sites based on User Experience metrics: * **LCP (Largest Contentful Paint):** How fast does the main content load? * **FID (First Input Delay):** How fast does the site respond when clicked? * **CLS (Cumulative Layout Shift):** Does the content jump around while loading? (Avoid this by defining height/width on images). ### 3. Meta Tags Ensure every page has a unique `title` and `meta description`. If you are building a Single Page App (SPA), ensure you are using a tool like React Helmet or switching to a framework like Next.js to handle Server Side Rendering (SSR) for better indexability.
