Semantic search engine optimization is just an extension of regular search engine optimization, chiefly by factoring in structured data into the "regular" optimization mix.
The goals of semantic search engine optimization may differ from those of traditional SEO. Among these goals:
"Semantic SEO" - insofar as it exists as an SEO disciple at all - is an emerging field, and as such very little in the way of formal optimization techniques and strategies have been developed aside from the markup of resources with RDFa and microformats for better visibility in Google.
The most common example cited by both semantically-savvy SEOs and SEO-savvy semantic web practitioners is the markup of resources for the generation of rich snippets in Google. This is not incorrect, but really represents a single realm of semantic SEO (as there are other search engines besides Google, and other types of search engine visibility besides rich snippets).
