A general overview of the different semantic markup formats and the existing technologies to incorporate explicit semantic information (microformats, microdata and RDFa) is provided. Services are described that automate, to some extent, semantic annotation processes ( Sindice ,  Calais ,  AlchemyAPI  and  DBPedia   Spotlight ), while characterizing the complete cycle of this process in a particular CMS ( Wordpress ) using a specialized plugin ( RDFaCE-Lite ). Finally, in order to quantify the creation and connectivity of semantically marked content on the Web, the space formed by all Spanish universities (and a selection of 25 international institutions) is analysed with  Sindice  . Semantic page count and visibility indicators (inlinks, outlinks, internal and third party) are calculated for the sample. The results indicate limited presence of semantically marked content in the universities and highly isolated web visibility of this content.
