Traffic on the Internet is the term for visitors to a website. Some service providers such as Alexa attempt to accurately show Internet traffic and not only that analyse the traffic behaviour for the most popular sites on the web. There is some controversy over the accuracy of most traffic measurement techniques (except those used by the webmaster on his or her own site of course) as they often rely on statistically biased samples – such as Alexa Toolbar users – to determine a big portion of their data.
The term is often combined with other marketing or Internet terms to mean visitors from that source – for example ‘Banner Traffic’.
