WHAT IS CANONICAL URL?

We started to encounter the question of what is Canonical URL frequently. The rel=canonical element, often referred to as a "canonical link", is an HTML element that helps webmasters avoid duplicate content issues. It does this by specifying the "canonical URL", the "preferred" version of a web page, even the original source. Using it thoroughly improves a site's SEO.

The idea is simple: If you have several similar versions of the same content, you choose a "canonical" version and point search engines to it. This solves the duplicate content issue where search engines don't know which version of content to show in their results. This article explains how and when to use them and how to avoid common mistakes.

ADVANTAGE OF CANONICAL URL

Choosing an appropriate canonical URL for each set of similar URLs improves your site's SEO. This is because the search engine knows which version is canonical; so it can count all links pointing to all different versions as links to its canonical version. Setting a canonical is similar in concept to a 301 redirect, but without actually redirecting.

HISTORY OF CANONICAL URL

In February 2009, Google, Bing and Yahoo! introduced the canonical link element - if you want to know about its history, Matt Cutts' post gives the clearest explanation. While the idea is simple, the specifics of how to use it are often complex.

TRANSITION TO CANONICAL URL

When you have several options for a product's URL, canonization is the process of choosing one of them. In most cases, it will be obvious: one URL will be a better choice than the others. In some cases, it might not be that obvious, but even then it's still pretty simple: just pick one! Not canonizing your URLs is always worse than canonizing your URLs.



How to set canonical URLs?

A correct example of using rel=canonical

Suppose there are two versions of the same page, each with exactly - 100% - the same content. The only difference is that they are in separate parts of your site and therefore the background color and active menu item are different - that's it. Both versions are associated from other sites, so the content itself is clearly valuable. So which version should search engines show in the results?

For example, these could be URLs:

http://xxxxxx.com/wordpress/seo-plugins/
http://xxxxx.com/wordpress/addons/seo/

That's why rel=canonicalicat has been created and unfortunately this happens quite often, especially in many e-commerce systems. A product can have several different URLs depending on how you got there. In this case you can reference rel=canonical as follows:
 
Select one of your two pages as the canonical version. This should be the version you consider most important. If you don't care, pick the one with the most links or visitors, and if all else is equal, flip a coin. You just have to choose.

Add a rel=canonical link from the non-canonical page to the canonical. So, if we choose the shortest URL as our canonical URL, the other URL

<head> will link to the shortest URL in the section of the page - like this:

<link rel = "canonical" href = "http://xxxx.com/ankara-web-tasarim" />



That's it! What this does is "merge" two pages into one from a search engine's perspective. It is "soft redirect" without redirecting the user. Links to both URLs now count as the only canonical version of the URL. If you are wondering about the results of the application as well as the answer to the question of what is Canonical URL, please contact Ansiklopedia !
