Glossary

Plain-language definitions of SEO terms used across the blog.

hreflang

An HTML and sitemap signal that tells search engines which URL serves which language/region — Google's primary mechanism for ranking the right page per audience.

Canonical URL

The URL Google should treat as the master version of a page, declared via `<link rel="canonical">` and (ideally) consistent across HTTP headers, sitemap, and hreflang annotations.
