If you need to have duplicate content, the canonical tag will go a long way in keeping your website’s SEO high and getting a good search engine ranking. In addition to aspects such as the title, tag and snippet, if you manage SEO for your articles, you must include the canonical tag to avoid being penalized by Google due to duplicate content.
Let’s start with the bases: do you know what a canonical label is? The canonical link was introduced by Google, Bing and Yahoo! in February 2009 with the aim of ordering duplicates and creating a simpler syntax. To understand what this is all about, let’s take a practical example. Let’s suppose that for your site you have created several pages with the same content. The reason could be content for your e-commerce site with small variations such as different colors or the same website adapted for mobile and desktop devices. If you know the SEO mechanisms, you know that Google penalizes duplicate content and therefore could penalize your site. This is where canonical etiquette comes into play. Its function is to indicate to the Internet analyzer robot that the site is a reference address for a given set of URLs.
Canonical etiquette can be much more useful than you think. Even when you don’t think you’re dealing with duplicate content. Inserting a canonical tag could be a tactic to apply. Think of your site. There are already two entrance gates https://www.miempresa.ltda/ o http://miempresa.ltda. For you and your users it is the same page, with the same design and the same structure. You have not made two different contents. However, when indexing your site, search engines like Google identify two different entities on the two pages. Here, even when we don’t expect it, we have potential duplicate content that will penalize our site. Often the choice of which URL to choose as canonical is not entirely obvious. In these cases, it is important to choose one anyway. Choose the one you think is most appropriate
