All of my domain names are undeveloped but some of them have an Alexa ranking. For example FreebiesDelivered.com is ranked around 15 million and gets 77 visitors a month? And another one I have ForeignExchangePrices.com is also ranked. How is that possible when they arent even searched terms. Why do some of my names get a ranking but most dont? Also should I hold on to the names that get a ranking? Thanks for any info
If users have the Alexa toolbar installed on their computer you will get ranked. It's a meaningless stat though.
The ranking is very webmaster focused. For example, web directories tend to have a high Alexa ranking because directory submitters will have Alexa installed. It doesn't necessarily mean the site is getting a lot of traffic.
