Welcome to the Q&A Forum

I am reviewing a website that has different activities, and there are many ways to sort them. The issue is that the website is essentially displaying the same information, but in different sorts. Take a look at this search page: http://www.kijubi.com/AC-Fishing You are looking for fishing trips here, but you can sort it by city, region, and category. I have decided to "no index" some of these sorts, but I am afraid they might be picking up some long tail traffic on the city and region sorts. For example, "newport beach fishing trips", something like that. Any suggestions on how to deal with removing all of these duplicate sorts, while still maintaining the traffic that may be received by sorting with some long tail terms?
