Why are google Pagerank, backlinks and other search engine metrics important?
You may want to pay more for a domain that already receive traffics, either from Google or other site. A domain with a pagerank is already indexed by Google and very likely to receive visits the minute you buy it. UpName only shows Google Pagerank and the number of backlinks on its search result pages, as these are the most meaningful indicators. However, you can see a wide range of metrics on the domain detail page.
