Links are very important in optimizing a website , for example, internal links make it easier and better for Google to realize the structure of a website, and through this type of link, website owners can specify the priority of websites and give more links to the pages which are more valuable. The use of backlinks also causes a website to be more reputable, it also has a great impact on the website ranking in the search engine results page.As mentioned so far, there are two types of links, which are internal links and external links, the two of which are different from each other, which we will explain each one separately.

What is Link Building?

Link Building is the process of creating a link which may cause the connection of two different pages of a website or the connection of two different websites together. These two types of links have a great impact on optimizing a website and search engines if the links are valuable and relevant to the website, Google will consider this as a positive point.Internal links, or in other words links that connect the internal pages of a domain to each other, have related topics. Depending on the number of links on a website, Google receives signals that the site is of good quality. This is also true for external links, but the important point is that these links must be created naturally and if you use methods which are contrary to the rules of SEO in creating links, not only the website will rank lower in the search results page, but also it will be penalized in some cases.

How do search engines use links?

Search engines use links to rank a website as well as to discover new pages. When search engines visit different pages of a website, they examine and extract the content of the pages and decide based on its content. Each link acts like a vote, however, the more quality websites which link to you, the more valuable these votes will be, and the more impact they will have on the ranking.As you know, Google offers different algorithms, which are becoming more and more powerful in determining the quality of websites. One of these algorithms is the Google PageRank algorithm , which was created to rank web pages and websites. The score that this algorithm gives is between zero and ten, which is measured through the inbound links of a website. In this way, if there is more inbound links to a website , the value of it will be more according to Google.In other words, each inbound link to a website counts as a vote to increase the ranking of that website, and another point is that the more value and credibility of that linking website, the more valuable that vote will be. This algorithm has become an important tool for Google, which is a great way to determine the quality of a page that Google uses. Simply put, when a website links to the content of another site, it actually means that the site is a good and trusted one to which it links. There are different links building techniques that SEO experts use to build links to get high rankings on the search results page. Of course, some sites try to use too many links to attract more attention from Google, in which case it will cause a negative ranking for the website, and it may be penalized.
