Building Quality Back Links
Save yourself a tremendous amount of time and effort by acquiring a few high-quality, authoritative links versus a large quantity of low-quality links that are not related to your web site. You can easily build a huge quantity of links back to your page by either manually submitting or purchasing software that mass-submits your web page to thousands of online guest books, forums, blogs, directories, and other link sources. However, this type of activity is often detected as span by search engines and therefore should be avoided. Search engines are becoming increasingly sophisticated and capable of detecting the difference between natural, relevant links, and unnatural, irrelevant links such as those typically submitted by software. Just one or two high-quality links can provide the same if not greater search-engine-optimization benefit than hundreds of low-quality links. All the major search engines, particularly Google, embrace this approach to link building.
