IP Canonicalization

---

IP canonicalization is a term that is often used in the field of referencing and web development.

This is a process which ensures that data and representations in various forms are treated in a uniform manner.

In this article, we're going to explore this concept in depth and explain in 10 key points what IP canonicalization is and why it's important for your website.

1. What is canonicalization?

Canonicalization is the process by which a number of URL or similar resources are made canonical, i.e. standardised and simplified. This allows search engines and users to work with a single version of the information, rather than having to manage several variants, some of which may be redundant or inaccurate.

Example of canonicalization

Let's take an example for a moment. Consider the following two URLs:

• http://monsite.com/page1
• http://www.monsite.com/page1

Although these two URLs lead to the same content, they are different for different browsers and different for different users. indexing robots. Canonicalization makes it possible to select a single URL canonical (for example, http://www.monsite.com/page1) and automatically redirect all visitors to this URL, in order to eliminate any confusion and improve referencing of the site.

2. The importance of IP canonicalization

IP canonicalization is crucial for several reasons.

Firstly, it ensures that the data and representations on your website are consistent and accurate, making it easier for users to navigate and improving their overall experience. In addition, by simplifying and standardising URLs and other resources, IP canonicalization reduces page load times and increases the chances that your content will be found and indexed by search engines such as Google.

Finally, it also avoids problems of duplicate content (duplicate content), which can harm your natural referencing.

3. IP vs. domain name

When we talk about IP canonicalization, it is important to distinguish between the IP address and the domain name. The former is a unique identifier assigned to each device connected to the Internet, while the latter is an easily remembered text address associated with the IP address of the server hosting the website. Both can be used to access the same website, but their use can lead to duplicate problems.

4. Problems caused by the absence of IP canonicalization

In the absence of IP canonicalization, visitors and search engines can access your site via different addresses or URLs, such as :

• http://monsite.com/
• http://www.monsite.com/
• http://123.45.67.89/ (server IP address)

Visitors may not notice this difference, but for the indexing robots, these separate URLs mean that the same content can be accessed at several different addresses. This can lead to duplicate content problems and reduce the relevance of your site in the eyes of search engines.

5. Canonicalization and referencing

A major problem posed by the absence of IP canonicalization is its impact on the referencing of your website. Search engines assign a relevance score to each page based on a number of criteria, including the quality and uniqueness of the content. If the same content appears several times under different URLs, it runs the risk of being considered duplicated and of being penalised in the search results, which is detrimental to your website's visibility and traffic.

6. The link rel= "canonical " tag

To facilitate the canonicalization process, Google introduced the link rel= "canonical ". This tag allows webmasters to clearly indicate which version of a page should be considered as canonical, i.e. the reference version to be used for indexing and ranking. In this way, you can avoid duplicate content problems and optimise your search engine optimisation.

7. 301 redirects

Another method of implementing IP canonicalization is to use 301 redirects. These redirects redirect visitors and indexing robots to the canonical version of each page, indicating that the location of the content has changed permanently. For example, you can use a 301 redirect to redirect all access via the server's IP address to the corresponding domain name.

8. Other types of canonicalization

IP canonicalization is a specific aspect of the general canonicalization process. There are also other forms of canonicalization which concern different elements of web pages, such as :

• Canonicalisation of URL parameters (for example, sorting the parameters in a uniform order)
• Canonicalisation of file paths (conversion of relative URLs to absolute URLs, removal of unnecessary slashes)
• The canonicalization of protocols (automatic redirection of HTTP requests to HTTPS for a better referencing and improved safety)

9. Tools and plugins for IP canonicalization

There are several tools and plugins available to help you implement IP canonicalization on your website. These solutions include :

• Plug-ins for content management systems (CMS) such that WordPress or Drupal
• PHP scripts and libraries, JavaScript or Python
• Online services offering analysis and recommendations for improvement

10. Things to remember about IP canonicalization

In summary, IP canonicalization is a crucial process for ensuring the consistency and quality of your online presence, as well as for optimising your website's SEO. You therefore need to put in place an IP canonicalization strategy tailored to your situation, using the tools and techniques available.
