The automated appraisals base a domainโs value on several metrics (search volume of the keyword, advertiser competition for that keyword, cost per click for advertisers, Google search results containing the keyword, age of the domain name, TLD (is it a .com, .net. org etc.), Google page rank, potential traffic etc. The automated appraisals are GREAT for compiling a lot of important data โ and I use them for this purpose every day.
