Technical SEO
Redirects, www or not, HTTPS, subdomain vs. subfolder.
- HTTPS Migration SEO: Checklist Without Ranking Loss
An HTTPS migration needs no Change of Address, but 301s, HSTS, mixed content fixes and canonicals. Google's HTTPS signal touches under 1 % of queries.
- Subdomain vs Subfolder: What Google Says and Why It Matters
Subdomain vs subfolder: Google says both work for ranking. The real differences are internal linking, Search Console setup and site reputation rules.
- WWW vs Non-WWW: Which Is Better for SEO?
WWW vs non-www makes no ranking difference to Google. What matters is picking one, redirecting the other with a 301, plus a CNAME catch at the apex.
