Hidden Links
So I do not see that interest may have for you, your page is part of a link farm. More spam tips in relation to the links. Although the link farms are the most popular for the “link spam”, although there are other less used, also bear fruit. Hidden Links. A spam technique that hides words to visitors, but shows them to search engines. The spammers who hide links do the same way, covering up the links with other content, allowing them to advance the search engines with hundreds or thousands of hidden links.
Blog and Guestbook spamming. Some spammers use programs to automatically include comments on their blogs and guestbooks. Many websites have eliminated their guestbooks response. Similarly the case with blogs. The solution in this case for bloggers has been to install a system that requires manual approval of the comments, so that they can not allow those who are suspect. Reciprocal Links reprehensible Another tactic is used by some spammers who try to fool you, instead of fooling search engines.
When they reach an agreement to exchange links with you should put yours in return for his appearing on your website. So far, so normal and logical. However, you must check the actual exchange and ensure that your “partner” is playing fair. Some spammers add a link to your page, but, and here’s the catch the link uses Java code to hide the link to your website to search engines. So you see that the link points to your page, but search engines do not. Why do this? The simplest would fulfill its part of the deal and not cheat as well. What happens is that search engines estimate that the link has more value “of a direction,” which comes from one page to another, that the converse, the real exchange. Check the link to your site by disabling Javascript, to be sure that search engines “see” the link to your page. Although not strictly a spam technique, search engines are becoming less favorably with the payment link, those in which one site links to yours in exchange for money. The search engines require that links labeled “nofollow”, so telling them that these links do not reflect “votes” to extol the quality of the site. According to some experts, paying for links is a good idea, but only in order to get traffic. Paying for a link when a visitor clicks on it might be worth (in fact the same reasoning you use to evaluate the possibility of sponsored ads in major search engines.) Search engines also improve and debug their tracking system so that each year it easier for them to find paid links and devalue their “vote.” So buying links to improve your position in search engines is not a good idea. One last recommendation, if your site has been banned or penalized by search engines for using some (or all) of the techniques described above, gives up and asks your practice rehabilitation and new indexing of your website. Usually this is immediate and automatic, but sometimes you must go through a period of “punishment”, so that is not carried out as quickly as you like.
