The document seen by PRWeek states the work will consist of strategy, advocacy and blogger outreach.
Nicola Dodd, head of PR and social media at Cancer Research UK, emphasised the importance of social media to the charity.
She added: ‘All our community management is done in-house but occasionally we need agency support for campaign or content creation.’
Last month the charity launched an advertising campaign ahead of its Race4Life events this summer, featuring the slogan: ‘Cancer, we’re coming to get you.’
An agency source with strong voluntary sector links pointed to the campaign as a sign of the power of social media: ‘There is no sense of the corporate presence of the charity in the ads, and that is a nod to the lessons learned from social media in terms of growing a sense of community.
‘With grant funding for charities dropping, public support is becoming more crucial. Organisations are having to become better at social media and engage in conversations with those who represent them externally.’
