Calum Maclean will have appeared on the For You pages of hundreds of thousands of people across the globe on TikTok in the past week as his search to find the real centre of Scotland clocked up more than 800,000 views.
His most watched video was one of him swimming in Loch Morar – the nation’s deepest – and has been seen more than 25 million times.
Communications agency Spey have named the keen cold water swimmer top in its list of Scottish influencers on the video app, beating ex-Love Island star Paige Turley, who came second, creator Lewis Buchan, who came third, and Forget Me singer Capaldi, who was ranked sixth on the list.
The agency said it ranked the list according to how often other users interacted with them, rather than just the number of followers they had amassed.
Jennifer Robertson, founder of Spey, said it was a “diverse list” this year and demonstrated the “impact of posting about issues that really matter to you”.
“Our top influencer, Calum Maclean, has led renewed interest in the Gaelic language amongst young Scots in particular, which just goes to show the passion we have for our Gaelic heritage,” she said.
“His posts about our breath-taking landscape and waters have also performed really well – in particular, his post where he filmed in the depths of Loch Ness went viral and helped him reach an audience of over four million.
“Ultimately, the results show the power of innovative content and how quality can trump celebrity.”
Mr Maclean, who goes by the username caldamac on the platform, had an engagement rate of more than 56 per cent among his 257,500 followers, meaning his posts are liked and shared more often by those who see them than any of his fellow Scots on TikTok.
Singer L ewis Capaldi came sixth with an engagement rate of 7 per cent among his 4.7m followers.
Also making it to the top ten list were newsagent and comedian Yasser Inayat, make-up artist Jamie Genevieve, and activist Eddie Walker.
