ok, so I have about 130 arbi pages so far, a few hits, a lot of misses. Just taking the advise of many "test, test, test!" Anyhow, I read a post from chrislingle that said his dublicate niche arbitrage pages didn't really affect the average stats of his originals. So I thought.. what the heck, I'll just make duplicate pages of my top paying niches with a new layout. It's working out all right so far (no negative affects from my own compitition). Has anyone else done this? Your thoughts?
