For exampel when I browse
http://www.webshots.com witch is probably an
american site I see that they have advertises on the site from my
country witch is Sweden. My question is how does that web page
reconise that I i'm from Sweden?
To make a long story short it can tell the IP address that you're making the
request from (the numerical address of your computer on the internet) and
looks that address up in a database. Certain countries are assigned certain
IP address blocks (range of numbers that are in use in that specific
country) and it just looks it up, figures out that those numbers are
associated with your country, and feeds you ads based on the country that
you're from. It's pretty simple really but not always effective as some IP
blocks are sold, transfered, or used for proxies. When, for instance, I use
compression software to speed up my browsing it appears that I'm coming from
an IP associated with the UK and Google automatically sends me to
google.co.uk instead of .com... It's a rather standard script and not very
difficult to implement but it's not always correct. There's software that
will use the same databases and allow you to look-up an IP address and
figure out where they are on the globe.
