Definition
Technical SEO covers the under-the-hood factors that make a site crawlable and indexable: canonical URLs, XML sitemaps, robots directives, redirect discipline, schema markup, hreflang, internationalization, performance, and accessibility.
Why it matters
A site with perfect content and broken technical SEO will not rank. WordPress and Webflow sites commonly ship with technical-SEO issues, duplicate canonicals, thin sitemap, unoptimized images, layout shift, that a custom Next.js rebuild fixes on day one.
How we think about it
Technical SEO is a checklist we run against every site we ship: 301 redirect from old URLs, canonical tags on every page, sitemap indexed at Search Console, structured data validated, Core Web Vitals green, WCAG-AA color contrast. The checklist has no yellow cells.
