Is Alexa a parasite? Some people think that it is. But I don’t agree with them. Alexa’s Toolbar is a Browser Helper Object (BHO), a component of Internet Explorer that will load whenever it starts, shares IE memory context, can perform any action on the available windows and modules. There is no version of Alexa toolbar which installs automatically. There is no version of Alexa toolbar which don’t have uninstall feature. Depending on the version it is in different places of the system. Yes Alexa gathers information about the web pages you view, the data you enter in online forms and search fields, and, with versions 5.0 and higher, the products you purchase online while using the toolbar service. Although Alexa does not attempt to analyze web usage data to determine the identity of any Alexa user, some information collected by the toolbar service is personally identifiable. Alexa aggregates and analyzes the information it collects to improve its service and to prepare reports about aggregate web usage and shopping habits. Online marketers use Alexa gathered information to evaluate websites. Some websites might say: a) we have more than a million visitors b) we established on 1999 c) we get millions of page views All this we can check with Alexa. Check it and you will be surprised how many sites spreads lies about themselves. What does these numbers means on Alexa? Alexa shows the rating of the website. Imagine that all websites of the internet are placed in a row. The closer to the start, the bigger site is. In common words I can say: Alexa from 1 to 1000 are the industry leaders, they get enormous traffic and can be named as the leaders of the internet. Alexa from 1000 to 10.000 are really huge sites, gets lots of traffic, usually are the leaders in their theme. Alexa from 10.000 to 50.000 are quite big sites, gets some global traffic. Alexa from 50.000 to 100.000 are average sites, they don’t have a lot of traffic, but usually these are the sites which are online for some time. Alexa from 100.000 to 500.000 are small sites, gets very small amount of traffic. Alexa from 500.000 to 1.000.000 are very small sites, usually just emerged in the internet. Alexa over 1.000.000 the new site, usually gets tiny amount of traffic or don’t get at all. Is Alexa information accurate? Not always. There are various exceptions to these statistics. Don’t use Alexa information as some kind of rule. It is just one of criteria to evaluate websites. Average Statistic gathered by asking something from the certain amount of people. The more answers you will get the more accurate statistic will be. Alexa computes traffic rankings by analyzing the Web usage of millions of Alexa Toolbar users. So we can say that their numbers are quite accurate. But there are exceptions. For example: 1. If you site is about the viruses and spyware – Alexa rank will be lower, because lots of people keen on security treat Alexa as parasite and simply don’t have toolbar on their computers. 2. Local sites gets less accuracy in the stats. If your site is Lithuanian, then you must know that your real stats are a bit different, because Alexa counts global traffic, not local. 3. If your site lets say created to Mozilla or opera community, you will get not so accurate statistic too, because toolbar designed for explorer, not for other browsers. And your site gets visitors who don’t use explorer and Alexa toolbar.
