The agency, which counts British Airways, Hilton, Superbreak and Hotelnet amongst its roster of clients, is expanding its travel vertical team and Reid will take on the role of senior search specialist.
Reid moves to Bigmouthmedia after five years at the Lastminute.com-owned All-Hotels.
Bigmouthmedia chief executive Steve Leach said: “We’re delighted to welcome Stewart to the team. He knows organic search for the hotel sector inside out and will be a valuable addition to our travel specialist department”.
Reid has been credited with spearheading All-Hotels’ major successes in organic listings across the range of search engines.
