We run a national search directory and have thousands of urls that are indexed with search results. I have several questions based on varying opinions that I have seen online.
1) Should these search results pages be set to crawl or not? Thousands of pages are indexed by Google (similar to our competitors) and contain important keywords (city and state, etc.), but I am unable to determine if we are penalized for this or should just leave them as being crawlable content.
2) Some of these urls have potentially duplicate content. Should I redirect these as 301s? I'm hesitant because we cannot have a drop in traffic. If traffic will drop, should I just leave them indexed but no longer a link on our site?
Any feedback would be greatly appreciated.
