If your main content is 100% reliant on JS to load, Google can take weeks to index it, or simply abandon it if the rendering time is excessive. This is why static HTML (SSR/SSG) is crucial.</p> </article><article class="rounded-2xl border border-gray-200 p-5"> <h3 class="text-lg font-bold text-black"> When should I use `canonical` tags vs 301 redirects? </h3> <p class="mt-2 text-gray-700 leading-relaxed">The `canonical` is used when both pages must functionally exist for the user (e.g. an ecommerce that allows sorting by price generating an URL parameter `?sort=price`). The URL with the parameter includes a canonical pointing to the main one. A 301 redirect is used when old pages die permanently and their traffic must be redirected.</p> </article><article class="rounded-2xl border border-gray-200 p-5"> <h3 class="text-lg font-bold text-black"> Are 'hreflang' tags really important on multi-language websites? </h3> <p class="mt-2 text-gray-700 leading-relaxed">Absolutely critical, or you will incur massive penalties for duplicate content. If you have /es/ and /en/, the `hreflang` connects both entities, telling Google: 'this is the Spanish version for users in Spain, and this is the English version'. They must mutually reference each other using absolute URLs.</p> </article><article class="rounded-2xl border border-gray-200 p-5"> <h3 class="text-lg font-bold text-black"> Can bad Core Web Vitals sink my ranking? </h3> <p class="mt-2 text-gray-700 leading-relaxed">Google's algorithm explicitly includes Page Experience metrics (LCP, INP, CLS) as a ranking factor. In competitive niches where content is equally good, the website that loads faster and blocks the main thread less will systematically win the top positions.</p> </article> </div> </section> <section class="mt-12 w-full max-w-4xl mx-auto"> <h2 class="text-3xl md:text-4xl font-bold tracking-tight text-black mb-6 text-center">
