Technical — so Google can read the site
- Every page loads its full content from the server, without depending on JavaScript. If the content only appears after code runs, many crawlers never see it.
- Sitemap and crawl file declared and kept up to date.
- Load speed: static sites, images in modern formats with declared dimensions, preloaded fonts.
- Clean, permanent addresses. One page, one address. 301 redirects when something changes.
- Security certificate and a single version of the domain: with www or without it, never both.
