I have few questions regarding how something is done. I enter the zip code of my town ( for example - Westby) at weatherdotcom and on the right of the page it says "Sponsored links in Westby" and underneath two ads: Code: "Acai Berry EXPOSED: Westby Westby Warning: Health Reporter Discovers The Shocking Truth!" and "Westby: Mom Discovers $3 Whitening Trick Dentists Do NOT Want You To Know About This Teeth Whitening Secret!" When you visit these pages: Code: channel6reports*c*m/health/?n=200&k=weather Code: consumersdigestweekly*c*m/?n=201 The first one shows a weather map of the state where Westby is, and the second one has the same map but also at the beginning it says: "Amy, a Westby school teacher..." My questions are: How are the ads made so that it shows the city you are in, and it spells it in the ad itself. How the sites find your location and change the text of their content ("Amy, a Westby school teacher..."). If you use proxy, it will spell the name of the town the proxy is from. What scripts or ways they use? Where can you find these templates they use? I have seen them on many different sites simillar to those ones. If you know anything else, please add it. Thanks!
