Frequently asked questions
What is a canonical tag?
A canonical tag tells search engines which URL is the 'master' version of a page when multiple URLs have similar or identical content — preventing duplicate content penalties.
When should I use a canonical tag?
Use it when you have URL variations (http vs https, www vs non-www, query parameters, trailing slashes) or when similar content exists at multiple URLs.
Can a canonical tag point to a different domain?
Yes — cross-domain canonicals are supported by Google. They're useful when content is syndicated or republished on another site.
