What is backlink?
Backlinks are links used as a reference in content, a link made from one domain to another.
They act as a recommendation about the material available on that page. For search engines, it is as if they are saying that the site produces relevant content on the topic and that it has the answers that users are looking for.
From these links, search engines understand which domains have relevant materials and assign points to these pages.
SEO: backlinks and their importance
Search engines use several factors to rank content. Google, for example, has more than 170 different factors. Some of them are: keyword usage, page loading speed, usability, user dwell time, among others. In this text we will talk about backlinks, one of the most important points for SEO.
When someone needs to hire a service and receives a recommendation from someone they trust that a certain professional or company does that job and does it with quality, it is very likely that they will look for the person they recommended and hire their services. This is how backlinks work. For search engines, they are seen as an indication and help them understand that content is relevant.
These mentions help websites gain authority and points with search engines, thus achieving better rankings. The points make the search engine display the material on its first pages, which are the most accessed, since no one usually looks at many pages before doing a new search.
One of the SEO strategies that blog owners adopt to get quality domains to mention theirs is called linkbuilding, with which they aim to increase the relevance of their website, to be displayed on the first pages, increasing their organic traffic.
But despite the backlinks are important, you need to pay attention to the quality of the backlinks received and made on your domain, as not all of them can bring benefits.
Mentioning an untrustworthy website or being mentioned by one can cause your website to lose relevance and quality in search engines, after all, it has been associated with a website that does not comply with the guidelines or does not offer relevant material. Spam and pornographic content sites are considered low quality.

Types of backlinks
anchor text
Anchor texts are clickable texts that will take the reader to a page where what was written in the text will be explained in much more detail.
This sentence is an anchor text and the reader knows that when clicking it they will be redirected to a page where there will be an explanation on how to generate leads, perhaps tips on how to do it, etc.
Juice Link
In this type of backlink, both the mentioned site and the mentioner share authority. The cited domain receives authority because it is seen as relevant content, and the citing domain receives the authority that the other site has, thus being perceived by search engines as a site that cites good content.
Nofollow link
When the link has the 'nofollow' tag in its HTML, the authority sharing mentioned in Link Juice does not happen, even if the other site is mentioned.
This type of link is used by those who do not want to receive negative backlinks and run the risk of being affected if mentioned by an untrustworthy domain.
Dofollow link
The 'dofollow' tag must be added to the link HTML for authority sharing to occur between pages.
Internal links
If a website owner is creating content and mentions other material on their own website to complement the topic, this is called internal links. These are links that lead to another page without leaving the domain. This makes users stay on the site longer, which also helps with rankings.
Low Quality Links
As mentioned earlier, receiving backlinks from low-quality sites can lower the quality and ranking of a domain. This type of backlink represents such cases.
Root Domain Links
'Root domain' links indicate that even if one site mentions the other multiple times, the exchange of authority will be with just a single link.
Conclusion
Always remember to pay attention to SEO strategies to be within Google's search parameters, including the use of backlinks. This way, your content has a much greater chance of being considered relevant by these search engines.
