Alexa Overhauls Ranking System

Everyone’s favorite web statistics whipping boy Alexa has announced a major overhaul of how it compiles traffic figures.The biggest change is Alexa’s decision to drop exclusive reliance on the Alexa toolbar for traffic data, with Alexa now aggregating data from “multiple sources” to compile its statistics and web rankings. As part of the move, historical data from Alexa is no longer available, with data now only going back 9 months (we presume calculated using the new methodology). Alexa is spinning the decision as a step forward without admitting to previous flaws.

Alexa.com is a subsidiary of Amazon.com. It is a website which provides information on traffic levels for websites. The Alexa rank is measured according to the amount of users who’ve visited a website with the Alexa toolbar installed. Alexa toolbar is an application developed by Alexa Internet. Its primary use is to measure website statistics. This toolbar collects as well as gives some valuable information. Once you install it, the Alexa toolbar monitors all your surfing and collects information about what domains you visit. They use this data to rank web sites. The traffic rank they assign to websites is based on 3 months of aggregated historical traffic data from millions of other users and is a combined measure of page views and users. Webmasters, advertisers and ad networks use your blog’s Alexa rank as a gauge to determine the worth of a link on your website. If you depend on link or site selling as a form of monetization you’ll definitely want to increase your Alexa rank, because it’ll increase your bargaining power when it comes to ad pricing.
