Cheeze will be tasked with helping drive trials and sales of Exclaimer software with businesses of all sizes, Microsoft resellers and IT consultants.
To achieve this, Cheeze will review Exclaimer's Google Adwords campaign and restructure the company's site for improved SEO.
Pete Oxlade, group account director at Cheeze, said: "Exclaimer is new to SEO so we'll be doing a full audit of the site, improving its structure and building lots of links and content to get them to the top of the natural search listings."
Chris Crawshay, CIO at Exclaimer, said: "Our aim is to build a new niche in IT software. Quite simply, Cheeze showed us that they really understood our business and its goals and had the relevant experience and expertise to help us achieve those objectives."
