Number of Visitors to the Ashfield Website

Every visitor to the ADC website has an identification number unique to their PC that is assigned by their Internet Service Provider (e.g. NTL) when they connect to the Internet.

This graph shows the number of unique identification numbers the ADC website has seen in each month.

We can roughly assume that this is the number of individual visitors to the ADC website.

This isn't entirely true, because each visit by a different person using a shared PC (e.g. in a school or library) will be assumed to be the same visitor returning, and so will only be counted once no matter how many actual individuals used the PC to visit the website. This tends to lower the values for the number of visitors.

Also, some Internet Service Providers assign a different identification number to a PC each time it connects to the Internet. This tends to raise the values for the number of visitors.

Assuming that the distortions to the values are proportionally similar month on month, this graph at least shows the trend for the number of individual visitors to the website, even if it is not the real number.
