City-wise Categorization

Dear experts!
Hope all of you are doing good. I have recently launched a classified ads website. I want to categorize in it cities, I mean, if anyone want to see ads of a single city he just need to click a specific link just like we can do in other classified ads' websites.
For reference, you may check my link: http://topklicks.com
