Galaxy Effect

It was a great analog using "Galaxy Effect" in SEM by one writer in Search Engine Journal. Earlier, I mentioned that online information is added everyday. With the vast of possibilities in searches, SEM will become irrelevant.

I would see this more as a "random sampling" method and once you define the keywords to help in your products & service, after conducting "experimental" campaign, I gathered you may find astonishing result which will up your yield.

SEM is definitely getting interesting!
