I have two websites that feature my two Jeeps. One for my Wrangler and one for my Cherokee. The Cherokee site gets about 120 uniques a day and pr of 2. The Wrangler site has a pr of 0 and gets about 30 uniques a day and growing. Would it be beneficial to combine these two sites together to a new url and use 301's from the old urls? Or should I just leave them as is? Any thoughts?
