Before I learned a lot about how things work, I bought some domain names that I thought would be good matches for niches that interested me. After learning a lot more, I recognize that my choices were more "seat of the pants" ideas than ones backed by search data. I have all the content lined up for a site in one of these niches now, and checking I found a domain name available that features the best search keyword in this niche. My dilemma, use my three year old domain that has just been parked in my namecheap account that is not a great match for the best search terms, or now buy and use a domain name that is a perfect match for one of the best search terms in my niche. Your thoughts or advice please.
