There are several things to take into account while optimizing your website for search engines.?

So let’s get started
What Is URL Canonicalization?
The process of choosing the best URL for a webpage when there are a number of possibilities is known as URL canonicalization.?
The purpose of URL canonicalization is to stop search engines from indexing and ranking several versions of the same page and to ensure that they only index and rank the preferred URL.
Multiple URLs can link to the same website for a number of reasons, including:
The authority of your website may be damaged and your SEO efforts may be negatively impacted if search engines scan and index each of these URLs as individual pages.?
By choosing one preferred URL and directing all other versions to that URL, URL canonicalization tackles this issue.
How Does URL Canonicalization Work?
By designating the preferred URL for a webpage and redirecting all other differences of that URL to the preferred URL, URL canonicalization works.?
A 301 redirect or a canonical tag can be utilized to do this.
An HTML element known as a canonical tag informs search engines as to which version of a URL is the recommended one.?
It appears as follows:
<link rel=”canonical” href=”https://www.example.com/page”>
It notifies web browsers and search engines that the original URL has been changed permanently to a new URL.?
This is an illustration of a 301 redirect:
301 Redirect: https://example.com/page -> https://www.example.com/page
Why Is URL Canonicalization Important?
Canonicalizing URLs is crucial for various reasons:
Avoiding Duplicate Content: Search engines may index and rank each version of a webpage as a different page when there are many versions of the same website. This may harm your SEO efforts and damage the authority of your website.
Improving Crawling Efficiency: Search engines have a crawl budget that they can spend on your website. You can make sure that search engines can crawl and index the most crucial pages on your website by minimizing the amount of URLs that need to be crawled.
Improving User Experience:? Multiple versions of a website might be confusing to users and make it challenging for them to locate the information they’re looking for. You may make sure that users are always taken to the correct version of a webpage by redirecting all variations of a URL to the chosen URL.
Consolidating Link Equity: When a webpage has numerous versions, the link equity (also known as “link juice“) produced by incoming links can be distributed among all of the versions. You may ensure that the link equity is concentrated on a single URL and thus increase the position of the selected URL on SERPs by combining all links leading to it.
Resolving Canonical Issues: By including parameters or session IDs in their URLs, websites may unintentionally cause canonical problems. Even if there are canonical problems, you may make sure that search engines index and rank the right version of a webpage by employing URL canonicalization.

When to Use Canonical URLs
Different Versions of the Same Page
Use canonical URLs to tell search engines which version of a page is the original when there are numerous versions available, such as versions for desktop and mobile devices or versions in various languages.
Similar Content Across Multiple Pages
Use canonical URLs to increase the authority of those pages and avoid difficulties with duplicate content if you have similar content on many pages, such as product pages with just small differences.
How to Implement Canonical URLs
Using the rel=canonical Tag
Use the rel=canonical tag in the head part of your HTML page to implement canonical URLs. Search engines are informed by the rel=canonical tag which URLs should be considered duplicate content and which versions of a page are the original ones.
Consider the following URLs, for instance, https://www.example.com/page and https://www.example.com/page/?ref=123, which both contain identical content. In this case, you would include the following code in the HTML page’s head section:
<link rel=”canonical” href=”https://www.example.com/page”>
By doing this, you inform search engines that https://www.example.com/page is the genuine URL and that the other URL should be regarded as duplicate content.
Redirecting URLs to Canonical Versions
Redirecting URLs to their canonical versions is another way to use canonical URLs. For instance, to avoid worries about duplicate content, you can redirect a URL that contains tracking parameters to the canonical URL.
You can use a 301 redirect to direct URLs to their canonical versions. Search engines are informed via a 301 redirect that the original URL has changed permanently to a new address.
In this case, you would add the following code to your .htaccess file if you wanted to change https://www.example.com/page/?ref=123 to https://www.example.com/page:
RewriteEngine on
RewriteCond %{QUERY_STRING} ^ref=123$
RewriteRule ^page/$ https://www.example.com/page/? [R=301,L]
You are informing search engines that the original URL has been changed permanently to https://www.example.com/page by doing.
