Technical SEO for React & Modern Websites | Tag Easy
Technical SEO fixes the foundation that decides whether a site can rank: crawlability, indexing, canonicals, Core Web Vitals, and structured data. For React and modern sites it means making every route render real, indexable HTML before any JavaScript runs.
Modern JavaScript sites often ship one empty HTML shell per route, so search engines index only the homepage. We fix the foundation — prerendering, canonicals, schema, and Core Web Vitals — so every page is crawlable, indexable, and fast.
What you get: Per-route prerendering / SSR and clean canonicals; Schema markup (Organization, Service, FAQ, Breadcrumb, Article); Complete sitemap with lastmod and correct robots directives; Core Web Vitals and image optimisation; Search Console + IndexNow submission.
