This technical SEO article answers a question that still comes up in client work and site migrations: should you use www or a non-www domain? The core takeaway is straightforward. Google does not rank one version above the other, so the real SEO issue is not preference but consistency.
The article explains that search engines treat www.example.com and example.com as separate hosts, which means you need to choose a preferred version, keep your internal links aligned, and redirect the alternate version properly. It also frames the topic through branding and implementation rather than myths about ranking boosts.
If you care about domain canonicalization, redirects, technical SEO, and URL consistency, this summary captures the key point of the original post: pick one version and stay disciplined everywhere.
