As far as I can tell, during my last 3 month contract with them, 9.4% of my online traffic came from them. This might continue even with a free listing on their site, I'm not sure. Of all those visitors, about 75% of them looked at at least 3 pages of my website and stayed on my website for 2 to 3 minutes. But almost 25% of those City Search referred visitors only looked at my main page and then closed the browser window or went away without looking at any of my other pages (like classes or parties).
Is $450 worth 5 months of advertising on City Search?
