When your computer makes a request to a website, it has to include information that lets the site send the information back to your computer.
That information can identify roughly where you are. The accuracy is about 95% and the precision is about city level.
It isn't anything to worry about, and the only way you can stop it is to have your requests come from a computer that is in a different location to you (e.g. using a proxy server). It really isn't worth the effort.
It really means nothing. They see your IP address and its' registered location. This means nothing, as it actually is seeing the owner's location, which is your ISP. If they are based in your town that is where it would say. My IP is always recognised as being 25 miles from where I actually live, as that is the ISP location. Quite often not very helpful, as when looking for maps it guesses my starting point as that location.How do web sites' advertisements know where you live?
When you access a website you download data from them. They can track where the data is going, if not all the way to your home, at least up to your internet service provider (which shows what town yur in). Can't fix that, thats how the internet works.
Maybe using a proxy server could throw them off and make them ping a different city. Try using a proxy server if yur worried.
Probably your IP (Internet Protocol) Address which are numbers identifying your internet service / modem. The structure of an IP address is xxx.xxx.xxx.xxx. People can tell from your IP address what country you live in or nearest capital city (I think).How do web sites' advertisements know where you live?
Every computer has it own IP address which knows your location then websites can access your IP address and see where you live and as if by magic there is a woman in your town waiting for you!
Hope this helps
they are based on the IP Address that you internet provider assigned to you... you can (maybe) avoid it by using some proxy servers...
