March 31 (Reuters) - British publishing firm Future Plc FUTR.L lowered its full-year margin outlook on Tuesday, as deeper-than-expected changes in Google search traffic hurt its higher-margin advertising and online shopping revenues, dragging its shares down nearly 30%.
The company attributed the decline to changes in Google's search ecosystem, which reduced visibility for higher-margin programmatic advertising and ecommerce revenue, while also driving pay-per-click (PPC) cost inflation across the industry.
The London-listed group now expects a core profit margin of 25-27% for the year, compared with previous expectations of around 30%. For the six months to March 31, margins are expected to be between 24% to 25%.
"Whilst we are disappointed with the impact of the changes in the search ecosystem on our near-term trading performance, we are making good progress in executing the elements of our growth strategy that are in our control," Chief Executive Kevin Li Ying said.
