The theme of inbound links has gained notoriety and now all we develop E-commerce activities we know that this is very important for the positioning of a website. Of course it is lawful and legal link to other pages, so much so, that has become a true and valid tool widely used to increase the popularity of your website address to search engines and get natural / organic positioning as it is called. But what is a link farm? Also called (Link Farms) is basically a website that contains many links and has been created with the specific purpose is to increase the PageRank of sites that post their links. It is very important that you clearly distinguish the difference between these sites and directories real genuine, and you request the latter to include your site. I do not think this method is used (look for links regardless of how) to achieve better positioning, and less if you have to pay for the links, I recommend getting links quality and this is a job that takes time. Some say that if you do, Google will penalize you, but this is not true, at most Google penalize the link farm, but if consultation with any professional webmaster seriously, “he will tell you that this form of attempts to improve the positioning is not is recommended and even less if you want a formal web site and gain prestige.
As many of these sites are created by spammers, there is something you should know, and you can have some problems with this practice as you have to register to enter and leave the site all your data, these are harvested and sold to companies which, in turn, are juicy e-mail lists, that they also sell, everything is business as you see. The truth is that this can start to get spam to your email box without knowing from where and in very large quantity, with the obvious discomfort and loss of time that this causes. You ever been offered lists with thousands of e-mail addresses for a few dollars? , Well I think I understand. In addition, as you no doubt I would like to join one of these lists, do not you be interested in buying. Finally: What is important is that you should not confuse, reciprocal links are, as I said, lawful and is valuable that you have on your website, but it is just one more way to improve the positioning, is not unique. The fact is that everything comes from working in the directory, publishing articles, creating interesting content, posting on blogs, participating in forums, etc. etc. Finally, the Link Farm are considered a form of spam by search engines, simply avoid them.
