Until the 7th of May, the BBC will be looking into how the Senedd election is unfolding on social media feeds across Wales.
On this episode of Walescast, Ben Summer from the News Impact Team, joins Fliss and James to explain how.
Using data and analysis from the National Centre for Social Research, he has set up six social media profiles for fictional voters based in different parts of Wales.
Ben is hoping they can give us a glimpse into the type of content people are being shown.
The full series of Undercover Voters will be available online on BBC Wales and Ben will be returning to Walescast weekly to provide updates.
It is based on a project by Marianna Spring who originally came up with this idea and used it in experiments for the Americast podcast and the 2024 UK General Election.
