Canonical tags are the best way of indicating to search engines which URLs you want to have indexed. A canonical tag or canonical link element indicates to search engines that a master copy of a page exists. Canonical tags are a powerful way of avoiding duplicate content; when similar content exists on more than one URL, a canonical indicates which is the more important URL so that Google knows which one to index.
Correct usage of canonical tags is therefore essential for SEO, as it shows Google which URLs should be indexed, and helps solve the problem of duplicate content.
What is a canonical tag?[edit]
The canonical tag is an HTML specification in the source code of a website, in the header area. It refers to a standard resource - the canonical URL - for websites with the same or similar content. If a canonical URL is correctly marked, search engines will index this source only, meaning that duplicate content issues can be avoided. Duplicate content has a negative effect on SEO, as it does not provide added value for the internet user. A duplicate content checker can be used to detect duplicate content.
Examples of canonical URLs[edit]
In general, when indicating a canonical URL, Google recommends absolute URLs, i.e. the entire URL including the protocol.
The following two URLs have the same content.
The first one is the standard resource, and the second one is a session as commonly used by online shops in order to be able to store user related data as e.g. items in the shopping cart. As the first URL is more important, this should become the canonical version, and the canonical tag should be integrated into the head element of the second page to refer to the first page. This will indicate to Google and other search engines that the first URL is more important, and that it should be crawled and indexed in the SERPs.
The canonical tag is placed in the metadata of the second URL. It looks like this:
When do you need a canonical tag?[edit]
It's important to use a canonical tag when content exists on more than one URL. This can occur in the following cases:
- The homepage can be reached from different URLs (for example www.domain.com, domain.com, www.domain.com/index.html and so on).
- Pages can be reached with and without Trailing Slashes (“/”) and with case sensitivity
- Because of URL Rewriting, the server only pays attention to one ID and admits variations of the address
- IDs (as Session-IDs or product filters) are used that don’t change the content
- Content is presented in different versions (e.g. print version, PDF etc.)
- There are HTTPS variants of the site
- The URL is still available under a HTTP version without SSL encryption
- Additional content is being published on other, external websites
Canonical tag best practices[edit]
- Canonical tags and pagination: when paginating websites with rel= 'next' and rel= 'prev', each page should refer to itself via canonical, or there should be a 'view-all' page, where all products can be visible in one overview. When using and, the best case would be to not use canonical tags. Instead, add a robot tag to the meta element of the paginated page (from the second page) and exclude the subpages from indexing.
- Canonical Tags and hreflang: If a website uses hreflang, the URLs should either refer to themselves with a canonical tag, or should not use a canonical tag at all. If both hreflang and canonical tags are used, Google receives conflicting signals. While the hreflang tag shows that there is another language version available, the canonical tag would make this version the original URL.
- Canonical Tags and Noindex: With the noindex tag, webmasters can convey to Google that a URL should not be indexed. If a canonical tag refers to this page, Google receives unclear signals, as a canonical URL is the relevant page a webmaster wants to be indexed. Webmasters should therefore decide between a canonical and noindex tag.
Frequent errors[edit]
Canonical tags are powerful. If applied incorrectly, websites or certain pages of a website may be completely ignored by Google, which could be a disaster for traffic and sales. Before implementing a canonical tag pointing to another page, a webmaster should firstly decide whether the content is in fact the same.
Frequent errors are:
- A canonical URL responds with a 404 status code. Canonical URLs must always be available, as a 404 error will confuse the crawler.
- Combining “noindex”, “disallow” or “nofollow” tags and canonical URLs is not recommended.[1]
- The canonical link element is in the body of a document and should not be used repeatedly in the meta data.
- A relative Path is specified as a canonical link element. This may cause the Googlebot to misinterpret the tag and it therefore loses its effect. For this reason, the link should always be specified as a complete URL in the canonical tag.
- The syntax is ignored. All characters should be taken into account when specifying the URL. It makes a difference if the canonical tag refers to https://page.com/ or https://page.com - the canonical tag should not refer from https to the http protocol. In January 2017, Google stated that the use of a secure HTTPS connection would become an important ranking factor for websites. Since then, Google has preferred HTTPS pages to canonical URLs.[2]. The Canonical tag should therefore point from HTTP protocol to the HTTPS page, not vice versa.
- The canonical tag refers to the homepage of a website. This would be incorrect as it would indicate that there are duplicates of a page.
- Canonical chains or cross-references: Incorrect use of the canonical tag results in canonical chains or cross-references. Target pages of a canonical link should not refer to other canonicals.

Importance for SEO[edit]

Canonical tags convey to search engines that there is a standard resource, or more relevant page, helping to resolve issues with same or duplicate content. It's important to ensure that the canonical tag is implemented correctly to avoid confusing search engines.
