London Marketing: Job Title Trends and Specialization Insights

I'm part of a London-based marketing leadership networking group, and someone has shared some initial research they've done analyzing 2.5 million LinkedIn job titles to get a sense of the landscape. A few interesting findings, so thought I would share! The trends show that there is movement towards specialisation, but at a slower pace than overall market growth (generalists shrunk by 2.8%, but the overall marketing talent pool grew by 11.8% since June 2020) Most careers plateau at manager level, with the conversion rate to Director and above decreasing by 23% since June 2020, with again generalist titles being favoured for leadership roles. As someone that's on the job market with a hyper specialized profile and relatively senior background, I can really feel this double-edged sword right now. Keen to get some thoughts and gut reactions on this?
