SMO - Social Media Optimization; the process of optimizing your social media pages in an attempt to gain more followers/likes/etc. which in turn helps boost social ranking signals on Search Engines.

SMM - Social Media Marketing is the process of marketing your product and/or service through PPC, Copy, and Viral Content.

SEM - Search Engine Marketing generally refers just to PPC. Generally someone who specializes in SEM is competent in running successful Adwords or other online advertising campaigns.

I don't think that there's any reason to answer this question because what @OP is trying to do over here is termed as signature spam I mean guys have a look at its signature... its totally work of some stupid seo person trying to look like an innocent ... :P

Now if only people would realize that Googlebot doesn't see our forum signatures!
