When it comes to organic search results, canonical tags are a must-have technique for avoiding duplicate content. In the terminology of search engines, “canonical” refers to one authentic page among several possible copies.

Duplicate content can hurt your website’s SEO by potentially lowering its search engine rankings. Search engines strive to deliver a variety of appropriate results, and duplicate content issues can confuse their algorithms.

Search engines can penalize websites for duplicate content penalties, leading to a decrease in rankings. This can impact the website’s visibility, traffic, and overall performance.

To prevent duplicate content issues, it is recommended to implement preventive measures like conducting regular site audits, utilizing canonical tags, content management, and creating unique and original content. The material should have valuable content. These practices help maintain a healthy SEO profile and enhance search engine rankings. A piece of content can rise and fall on the website.

In the HTML <head> section of a website, canonical tags are contained on a single line of code. Visitors can’t see them, but search bots can.

Look at Kohl’s example, which adds a canonical tag to a Bedding and Bath sale page.

What is Canonical?

When search engine crawlers come across a canonical tag, they check the URL within the tag against the URL of the page they are currently exploring. They will be viewing the canonical version of the page if the URLs are identical. In that case, the bots can decide not to index the page and instead give more weight to the canonical version’s links.
The following URL appears in the image above: https://www.kohls.com/sale-event/bed-and-bath.jsp?cc=bed_bath-TN1.0-S-bedbath. This is the link to the Kohl’s Bedding and Bath sale website. The canonical tag, however, indicates a more orderly version:

http://www.kohls.com/sale-event/bed-and-bath.jsp is the URL of the sale page.

As a result, search engines are likely to only index the version with the option (“?cc=bed_bath-TN1.0-S-bedbath”).

A Guide to Putting

On e-commerce websites, canonical tags that reference themselves are typically present by default. The canonical tag would contain the URL of the page located at https://www.site.com/cat/prod-123.jsp:
The sentence seems to be a link rather than an actual sentence; hence, it cannot be paraphrased.

However, duplicate material might arise from an e-commerce site in numerous ways. Possible examples of duplicate content for the URL https://www.site.com/cat/prod-123.jsp are:

Following are the tracking parameters: https://www.site.com/cat/prod-123.jsp?source=123.,
Various product routes leading to distinct URLs: https://www.site.com/cat/subcat/prod-123.jsp.,
A subdomain that is identical to another: https://shop.site.com/cat/subcat/prod-123.jsp.
Query strings: https://www.site.com/en/shop/c-ABC/p-123.jsp have annoying system-generated URLs.

Again, by placing the same canonical tag on each page, we can persuade search engines to ignore those four duplicate pages:

<link rel=”canonical” href=”https://www.site.com/cat/prod-123.jsp”/>

It may be as easy as updating a title tag on your e-commerce platform to modify canonical tags for each page. On the other hand, having a developer handle canonical tag management programmatically is the way to go.

Canonical tags are also useful for controlling the display of content syndication on other websites. The content’s duplication is determined by the words, not the layout or typeface. The same holds for excerpts that link to complete versions on different sites; this is also considered a duplicate content issue.

Without canonical link elements, search engines will prioritize pages according to the date of posting, number of inbound links, internal links, canonical links, external links, link metrics, or some other algorithmic metric. Use canonical tags, and make sure your syndication partners do the same for accurate rank assignments.

Additional Choices

In addition to tags, the XML sitemap, HTTP headers, and 301 redirects are the other three methods to provide canonical URLs.

When you create an XML sitemap, you may specify which URLs you would like search engines to crawl. Canonical URLs can be efficiently sent via XML sitemaps when implemented correctly. Search engines are left to suppose that there are duplicate pages because many sites either do not properly run sitemaps or do not note non-canonical URLs.

A canonical URL can be indicated in the HTTP header of non-HTML file formats, such as PDFs. Take the case of identical text on both a web page and a PDF file as an example. Since the page houses your site’s navigation and CTAs, optimizing it for search engines is important. Using canonical link elements that reference themselves within the page, like:

<link rel=”canonical” href=”https://www.site.com/cat/prod-123.jsp”/>

Then, when the server sends the PDF, provide the page’s URL parameter in the link element of the HTTP header to make sure it doesn’t rank:

link: <https://www.site.com/cat/prod-123.jsp>; rel=”canonical”

Being a meta tag in HTML code and a statement in an HTTP header, the syntax is different, although the elements are comparable.

Keep in mind that canonical tags are merely suggestions. Once again, authority signals and relevancy will determine which page is the canonical version for search engines. Using the URL Inspection feature in Google Search Console, you can see the canonical page for any validated URL.
With a 301 redirect, you can remove identical content more aggressively. This sophisticated canonicalization tool instructs search engines to (i) remove the old URL from indexing, (ii) add the new URL to indexing requests, and (iii) transfer the link authority from the old page to the new one. A 301 directive, in contrast to a canonical tag, expresses an order rather than an invitation.
