Lansons replaces Seventy Seven PR, the incumbent of almost two years, which declined to repitch in a four-way battle for the account (PRWeek, 7 July).
The rethink comes as eBay seeks to market PayPal separately from its own brand, a move that began with the appointment of PayPal's first UK head of PR, Christina de Parres, earlier this year.
‘We wanted an agency that had a good understanding of the financial services sector,' said de Parres.
Lansons joint managing director Ian Williams heads the account.
This month, PayPal expanded its ‘Text 2 Buy' service. It allows UK users to buy magazine subscriptions and consumer electronics via their mobile-phones.
In March, eBay's classified site Gumtree called in Cow PR (PRWeek, 3 March).
