SEO Expert more payable then SEM.

There is no comparison, It all depends on how well you can sell your services and market yourself. And how good your delivery is.

What is the Difference Between SEO and SEM? The difference between SEO and SEM is simply that Search Engine Optimization is part of Search engine marketing or Search marketing as it is widely known. ... SEO is about optimizing your website to get higher rankings in the organic search results while SEM goes beyond SEO.
