According to Word, the spelling is correct both as “traveling” and “travelling”. I happen to think traveling, with one “L” is more accurate. When I decided to buy the domain “travellingauditor.com”, I initially wanted it with one “L”. But, alas, it was taken. But, since it truly embodies who I am and what I love (travel will always be my first love), I decided to buy the domain with two “Ls”. Who knows, maybe I will get some internet traffic from the other people who prefer to spell it with one “L”. Thanks for checking out my page.
