The domain name industry is extremely active and competitive, which makes it no surprise that so many people are becoming involved in buying and selling domain names on a daily basis One of the best ways to obtain a valuable domain that is already search engine optimized is to purchase existing domains via auction sites. This strategy can be beneficial mainly in two ways. Firstly, any domain that has already been purchased was probably already researched for potential benefits. Secondly and more importantly, the second benefit is that many recently expired domains still retain some of the search engine optimization attributes that were built up by the previous owner.
