Kamakeli Srungaram Kathalu - Taappu Evaridhi

Alexa ranks sites based on tracking information of users of its Alexa Toolbar for Internet Explorer and from integrated sidebars in Firefox and Chrome. Hence the page is only ranked between users who have these sidebars installed and may be biased if specific audience is reluctant to do this (Windows Defender has classified the sidebar as malware while it assigns it to trojans). Also, the rank is based on three month data and takes a long time to reflect changes in content that may happen after the domain has been sold[citation needed]. Finally, low ranks cannot be accurate not just because of the lack of data but also because of statistic laws related to the long tail distribution.
