Search Engine Marketing or SEM is the term that is often used to describe paid search advertising. At Drozian Webworks we think that isn’t accurate. To us SEM should be the all-encompassing term for “search engine marketing” which includes both paid search and organic search. While the two components can be managed separately we recommend that DMOs use the same company for both services, since they are so closely tied together. At the very least, your paid search team and organic search team should be working very closely together.
