Link Farming, definition and uses

 What are Link Farms?

Link farms are a group of knowed websites between them that constantly exchanging links in order to improve the current positioning of all the websites they link. This practice is not very friendly in SEO and is currently in a big disuse due to the problems it causes in terms of positioning once the search engine detect it, so try to avoid it.

Another of the practices that were carried out in the past, but which caused the search algorithms to evolve in order to put a stop to them. Currently, Google and the rest of the engines reward the quality of the contents and the natural location of the links in these, as well as the authority of the place from which the link is made and the objective. 

This change has meant that all the web grouped that used to resort to these practices have completely collapsed. The link farms were developed to improve the page rank of different websites, although currently they only cause problems by receiving penalties from Google or other engines.

It should be noted that they differ from web directories in that the latter link, but provide context and in order to be useful to visitors. Moreover, they do not have hundreds or thousands of links plaguing all their contents.

What are Link Farms for?

The link farms were used so that all the websites linked to them could improve their page rank and, therefore, achieve a better organic positioning in search engines, especially in Google. It was a fairly common practice in the past, now it is illegitimacy of its implementation and because it brings more disadvantages than advantages if you don't use it well.

Take car and remember than receiving back links from these types of websites usually directories diminishes your page's reputation and therefore its position. Therefore, they are something to be avoided as much as possible.

Structure of the link farm

Link farms are often websites that do not contain any relevant content and only serve to build links. Websites that are exclusively dedicated to link cultivation can also be called link networks. These sites are useless for visitors, as their only purpose is to refer to other websites and thus increase their link popularity. They are supposed to increase the Page Rank according to the number of links that refer to the website in question.

Until a few years ago, these methods worked, but search engines are getting better at identifying spam, link networks and other black hat methods to explore techniques such as cloaking.
The use of link farms is targeted by Google and is considered spam. If a link farm is detected, it will either appear at the bottom of the search results or be removed from the search engine index entirely and therefore no longer accessible to users; so you already know if you don't use it well.

Relevance for SEO

Furthermore, Google will penalize any other website that is connected to such a link farm, as links from previously identified networks are generally considered to be harmful. Google not only evaluates the number of links, but also their quality. A senseless abundance of links that are in no way related to the content of the website are devalued by search engines and will then negatively affect positioning.

As a result, the linked websites will slip into the search results lists. This happens quite regularly and website operators and agency clients are well advised to refrain from this type of black hat SEO or if necessary to inform their contracted agency that they want natural link building. If you already have link farm links, they should be identified and removed. This requires first a detailed analysis of the backlinks and then all malicious links have to be removed manually. Subsequently, a reconsideration request can be sent to Google.
