The cruise firm is gearing up to launch a web-based booking facility this summer and will use Cheeze to develop a six-figure marketing campaign that will break in the next few months.
Planned activity will include search engine marketing, banner and rich media ads designed to increase its internet-generated revenue.
Cheeze was appointed following a competitive pitch against incumbent Unique Digital and Smarter Communications.
Fred Olsen currently operates three ships based mainly in the UK, offering holidays to the Mediterranean, South America and the Caribbean. The company is in the throes of expansion and is in the process of acquiring a fourth vessel to cash in on the growing popularity of cruising.
