  1. What are Canonical URLs?

A canonical URL is a URL that tells search engines the preferred or original version of a webpage. When multiple versions of the same webpage exist, search engines use canonical URLs to determine which version to display in search results. This can be useful for websites that have duplicate content, different URLs for the same content, or multiple versions of the same webpage. 

  1. How Canonical URLs Work? 

When a search engine crawls a webpage, it looks at the webpage’s HTML code to find the canonical URL. This URL is typically included in a rel=”canonical” tag in the webpage’s header section. The rel=”canonical” tag tells search engines that this is the preferred version of the webpage and should be used in search results. 

  1. Impact on Technical SEO. 

Canonical URLs can have a significant impact on technical SEO. Here are some ways in which they can affect a website’s search engine visibility: 

  1. a) Prevent Duplicate Content Issues: Duplicate content is a common problem that can harm a website’s SEO. When multiple versions of the same content exist on a website, search engines may have difficulty determining which version to display in search results. By using canonical URLs, website owners can tell search engines which version of the content is the original or preferred version, helping to prevent duplicate content issues.
  2. b) Consolidate Link Equity: When a webpage has multiple versions, the link equity may be split between those versions, reducing the value of each version. By using a canonical URL, website owners can consolidate the link equity of all versions of the webpage to the preferred version, increasing its value.
  3. c) Simplify Website Navigation: Websites with multiple versions of the same content can be confusing for users and search engines. By using canonical URLs, website owners can simplify their website’s navigation by directing users and search engines to the preferred version of the content.

  1. Best Practices for Using Canonical URLs. 

To ensure that canonical URLs are used effectively in technical SEO, website owners should follow these best practices: 

  1. a) Use Canonical URLs for Duplicate Content: When multiple versions of the same content exist on a website, website owners should use canonical URLs to tell search engines which version is the original or preferred version.
  2. b) Use Self-Referencing Canonical URLs: When a webpage has a canonical URL, that URL should be referenced in the rel=”canonical” tag. This ensures that search engines understand that the webpage is its preferred version.
  3. c) Use Absolute URLs: Canonical URLs should use absolute URLs to ensure that search engines understand the preferred version of a webpage, regardless of the web page’s location.
  4. d) Monitor Canonical URLs: Website owners should monitor their canonical URLs to ensure that they are working correctly and that there are no issues with duplicate content.

In conclusion, canonical URLs are an essential component of technical SEO. They can help prevent duplicate content issues, consolidate link equity, and simplify website navigation. Website owners should follow best practices when using canonical URLs to ensure that they are effective in improving their website’s search engine visibility.
