What are Canonical Tags?

A canonical URL is the version of a webpage chosen by search engines like Google and prioritized to avoid showing repetitive content that does not provide unique value in search results. If you have two pages on your website and both have similar content.

Let's suppose we have two pages

indexly.ai/p1

indexly.ai/p2

If both pages have similar content then you would add a canonical tag to the HTML code of one of the pages, let's say the page is indexly.ai/p1. This tells the search engine that the p1 page is the canonical version and should be indexed

Why Canonical tags?

If two sites have the same content then it will be a case of keyword damage and as a result, both of your sites will compete for rankings.

Google doesn’t always make the decision you want. However, you can influence canonicalization by using canonical tags. In the Google search console, you can mark one of those pages as “canonical” which means “main” and it will appear in search results and others will not.

This can be done by specifying the canonical URL using the tag in the HTML header

<link rel="canonical" href="...">

Website owners signal to search engines which version of the content should be indexed and displayed in search results. This helps prevent issues such as duplicate content penalties and ensures that the desired version of the page ranks well in search engine results.

While implementing canonical tags can seem straightforward, several common pitfalls may arise:

  1. Multiple Canonical Tags: If two or more canonical tags are present on a page, search engines may become confused. Review the page source and ensure that only one canonical tag exists. Solution: Remove any additional canonical tags from the page.
  2. Incorrect Canonical URLs: Sometimes, the canonical URL itself can be incorrect or non-existent.Solution: Double-check that the canonical URL accurately reflects the correct page and resolves properly.
  3. Ignored Canonical Tags by Search Engines: Occasionally, search engines may choose to ignore your canonical tag due to quality or trust issues with the content. Solution: Enhance your content quality and ensure there are no hidden technical SEO issues.
  4. Mixing Sitemaps and Canonicals: If your sitemap lists multiple versions of a page that have canonical tags pointing elsewhere, you create inconsistency issues.Solution: Streamline your XML sitemap to include only canonical URLs.
  5. Not Using Canonicals Where Needed: When you have pages that are similar but not exactly duplicate content (e.g., product variations), failing to use canonical tags can lead to dilution of page authority. Solution: Assess the similarity of your content and apply canonical tags as necessary.
  6. Ignoring www vs. non-www: If your site can be accessed as both www and non-www versions, it can lead to duplicate content. Solution: Choose one version as your standard and use a canonical tag to direct to it.
