UU/V Explained
The UU/V "Unique User/Visitor" statistic is the most commonly accepted measurement of popularity for an internet property and is used by websites, marketing firms, and investment companies to quantify the breath of their audience, justify the price assigned to advertising units, provide a basis for appraising the value of the internet property "website".
However, it is inherently overstated since the method of consumption for a website is mismatched with these other media like "tv, radio, and newspaper" due to the internets multiple channels of distribution of content.
So what is an "Unique"?
A "uNiQue" is the internet industies atttempt to create a metric that is
comparable with the TURF (Total Unduplicated Reach and Frequency) metric used
in television, radio and newspaper to measure the distribution of their
respective content to a number of distinct consumers.
According to IFABC "International Federation of Audit Bureaux of Circulations"
Global Web Standards, a unique user (UU) is "An internet protocol "ip" address
assigned to the internet device, plus some other unique identifier over a
specified time period".
So why is the "uNiQUe" statistic unreliable/inflated?
Assume the following case and you will quickly see, why it is so unreliable and inflated?
You have a favorite site that provides you with news and information regarding widgets and you follow this site as much as possible.
"uNiQue #1" - You access the site on your home computer with a good cup
of coffee.
"uNiQue #2" - You access the site on your cellphone, while you are on the
train or bus to or from work. Please do not drive and surf ;)
"uNiQue #3" - You access the site on your work computer, of course on your
break. ;)
"uNiQue #4" - And finally when you go to bed you access the site on your
tablet.
Total Distinct Consumer: 1
Total Unique Users: 4
The example website has one (1) "uNiQue" user, but the log data represents four (4) uNiQue users and the number is easily inflated by a factor of four "4".
Other things can cause general "uNiQue" inflation?
Multiple internet browsers: Many computer users have multiple internet browsers installed on their machine. So accessing the same site on the same computer with two different internet browsers will cause two "uNiQue" users.
Cookie Flushing: is the process of removing all the cookies from your internet device or in simple terms. If you delete your "temporary internet files", access sites using proxy servers or use the private browsing function of your internet device.
bots - These are the white hat bots like "Google, Yahoo, etc" and other content aggregators that scour your site for indexing on their site. While you always want them to index your content, they are not real "uNiQue" users.
Malicious bots - These are the programs/bots that access your website looking for security lapses that would allow them to commondere your site or comprimise your server for their use. While their goal is not to help you, and your server may be secure, it is their purpose to look like normal user traffic and so are counted as an "uNiQue".
