A lot of people tend to want to use a magnifying glass, which could be good if it can be done in a very original and progressive way. But, the magnifying glass is already a circle, so it could possibly be used as the "O" in "SEO". Or it could be used to create a symbol that goes along with the wording theSEOeffect.
Also, I am interested in seeing some ripple effect coming off of it, sort of like from a water drop, and I like the idea of "trending up" inside the magnifying glass.
The idea is... the magnifying glass represents search engines, the trending up inside the magnifying glass represents a website getting more traffic and better results, and the ripple effect coming off of the magnifying glass represents the effect that good SEO can have on your web marketing.
