A canonical tag is a snippet of HTML code that tells search engines which URL is the “master” or authoritative version of a page. It’s like informing search engines which version of a story is the original, so they know which one to show in search results.
Why Use Canonical Tags?
- Avoid Duplicate Content: Websites often have content accessible through multiple URLs. Without a clear favorite, search engines might split the value among the duplicates, diluting search rankings.
- Consolidate Ranking Signals: It helps pool SEO strength. Instead of having several weaker pages, you have one stronger one in the eyes of search engines.
- Choose Preferred URL: You get to tell search engines which version of a page you want people to see.
In essence, canonical tags simplify SEO by guiding search engines toward the content you value most, ensuring your SEO efforts aren’t split across similar pages.
