Have you noticed that when you go online or login to social media you are presented with content, news, articles or ads that somehow know the things that you are interested in?
It makes sense that you will see updates from people or organisations that you follow, but what may be less obvious are the algorithms (complex mathematical formulas) working in the background which determine what content is presented in your newsfeed or search results. Platforms such as Google, Facebook, Instagram, and Tik Tok all have their own closely guarded algorithms which personalise the content they show to us – different users who use the exact same search terms or scroll through the same social media platform are likely to see different content. The results that we are presented with are likely to reflect the likes and interests that our browsing history and personal data suggests we would like to see more of – after all, online platforms want you to use their site and to stay for as long as possible.
