You don't have to tell anyone in the Search engine marketing industry about the value of link building services. Whether gained freely or rented on a monthly basis, a link is a major rank boosting factor. As even the Google Guy will tell you, getting more links from quality Web sites is the key to ranking success and visibility in the Google search engine.
Why are links so important? Search engines have adopted a community concept of Web sites. The belief is that Web sites are controlled by people who know each other, and these people place links to other web sites willingly because they consider those sites valuable in some way to their visitors. If a site had hundreds of links leading to it, then it was considered a worthy Web site, and search engines tended to rank these popular sites more highly in the search results. This is where the concept of link popularity began. The well linked to site was popular and the number of links meant it was worth visiting.
As people learned of search engine's high regard for links, they traded links with other Web site owners. It was considered an equal trade and both parties benefited. It was an artificial link arrangement however, only for ranking increases rather than being a "vote of value" for each other's Web site. As the quality of search results depreciated, search engine companies had to do something about it and they've basically disregarded these types of exchanged links. Now, they value one way links, which is a link from one web site to another with no link in return. They also value links from sites that are on similar topics or have a reputation for being about a similar topic, which all plays a part in determining pagerank.
Therefore, just increasing the number of links to your site won't have an appreciative effect on your rankings. There is a quality element that search engines look for and analyze. With all their analytical capabilities, search engines can determine what a Web site's main topical theme is. They can also analyze what links "say" about the site they point to. If a link on a sports site says sports equipment in the text of the link, and links to www.abcsportsequipment.com, then search engines will consider www.abcsportsequipment.com a site that is relevant to sports equipment searches. If the site itself has a strong reputation for being about sports equipment, it may be considered an authority site. An authority site has special ranking powers and links from it can provide a big ranking boost to the site being linked. You'll definitely want links from an authority site.
There are many good sites to try to acquire links from, however most of their owners will not want to link to your site. In fact, few will want to without good reason. Everyone knows the value of building links today and few will give them for free. You'll either have to find a way to persuade Web site owners that your site is a good one for their visitors to visit or you may have to rent a link on their site. Renting monthly links can be very expensive. If you need two hundred links to make your site rank well in a competitive keyword area, renting links could cost you several thousand dollars a month at minimum.
For some companies, renting links can provide a good boost to rankings and the revenue the site generates makes the purchase justifiable, in fact, it might be an essential investment. Not getting rankings means not getting traffic or sales.
