One of the best things you can do when trying to make money from domain name investing is to optimise your existing websites. There are a lot of elements that can make a difference to your Google Pagerank and get you near the top of list for searches relating to your main keywords. A Page listing can make a huge difference financially, even when compared to being the number one on Page 2. I found the book Getting Into Bed With Google by Jon Smith to be an excellent read that will doubtless repay itself many times over in the years ahead.
