Spammers also pay attention to the Alexa rankings; other don’t! The Alexa rankings are are rating of website based on the traffic that a website gets from those who have the Alexa tool bar installed in their browser. The lower a website Alexa score, the more traffic a site is supposed to be getting. There are many ways to fake an Alexa rankings and there are services that can lower it for you. Spammers will go to many lengths to make their site appear better based on the Alexa rankings. I have no idea what they would want to do that for. The Alexa rankings count for nothing. They are not used by the search engines for rankings or anything like that. But, hey, since when as that stopped a spammer doing anything? Despite all that you still see them asking in forums how to improve it!
