I am working on several sites targeted to the Spanish and Latin America audience. One of them is for real estate - bulgarian properties. The others are about constructions and International fairs and exhibitions for textiles.
More than 90% of Spaniards use Google, it is (or was until recently), the strongest google bastion, in Central and South America the proportions are about the same as in the US, slightly better for google. Searching for omnibius will lead you to a Hispanic directories directory.
