Canonical URLs (SEO)

Why Using This?

Canonical URLs solves the content duplication (multiple urls representing the same post/page) problem. Using canonical urls prevents search engines lowering your site’s ranking due to content duplication.

How it works?

It’s simply an HTML <link> tag at the <head> section with attribute points to the right or “canonical” url.

Usually one uses a SEO plugin to generate this tag automatically.
