BP has lost its position as the best FTSE 100 social media user to Diageo.
FTI Consulting's annual report on FTSE 100 companies' use of social media has found that while firms are achieving increased engagement on posts about their financial results, there are still plenty of laggards.
The fifth Social Divide index from the company's strategic communications division has named Diageo the company making best use of social media around full- or half-year results time, overtaking BP, which was the top dog in both 2016 and 2015.
It also found that 31 firms did not publicise or discuss their results on Twitter, YouTube, LinkedIn or Slidershare in any form.
Of those 31, FTI report author and head of digital Ant Moore said: "Companies may take a view based on the moment in time, their sector, their company’s performance and the views of their investors and shareholders. It shouldn’t be social for the sake of it and that’s a key benefit of having an integrated team involved in planning."
FTI analysed results-related content across the four platforms, and based rankings for each of the 69 firms that did use social media on the basis of quality of posts, and engagement achieved.
The total of 17,085 shares, comments, likes and other engagements was twice as high as in 2016's report - and last year's report had also recorded a doubling of interaction with such content top against the year before.
However, a large part of this engagement (42.5 per cent) came on posts from just four firms.
Having been top of the pile for the last two years, BP slipped to second in FTI's rankings, with Diageo climbing from 13th to top spot. The top four was completed by GSK and Tesco.
The study also highlighted Shell as the top company for YouTube use.
