The term “canonical tag” refers to a feature of some search engines that, when applied to a URL, instructs the engine to treat it as the main copy of a web page.
Using the canonical tag prevents duplicate or identical content from showing up on many web address URLs.
The canonical tag informs search engines which version of a URL you prefer to appear in the search results.
In other words, the canonical tag is a feature of some search engines that tells the engine to treat a certain webpage as the main copy of that page. This is useful for preventing duplicate or identical content from appearing on multiple web addresses. The canonical tag tells search engines which version of a URL you want to appear in the search results.
The canonical tag is a tool that can be used to help improve your website’s SEO. When applied correctly, it can help to prevent duplicate content issues and ensure that your pages are properly indexed by search engines. canonical tags can also be used to point search engines to the correct version of a page, even if there are multiple versions of that page available.
The key difference is that when a search engine sees this tag, it doesn’t rank the page, but it does transfer all of the rankings to the canonical page. In other words, it’s comparable to 301 redirects. The rel=”canonical” attribute allows you to notify search engines where the original master version of a piece of content may be found. You’re essentially telling the search engine, “Hey, don’t index this; instead, index this source page.”
The canonical tag is here to save the day if you want to republish a piece of content, whether slightly or significantly altered, but don’t want to create duplicate content.
There are several situations where you might want to canonicalize a page:
– You have multiple domains and want to canonicalize all traffic to one domain
– You have www and non-www versions of your site and want to canonicalize all traffic to one version
– You have pages with similar content and want to canonicalize all traffic to one page
– You have pages with parameters and want to canonicalize all traffic to the canonical version of the page
If you’re not canonicalizing your pages, then you run the risk of having duplicate content, which can hurt your SEO efforts. By using the canonical tag, you can tell search engines which version of a page is the original, and which ones are duplicates. This helps search engines index your content correctly, and can give you a boost in the SERPs
