A feed is a representation of content that you can scroll through. Often the content on social media is displayed in an orderly manner, for example in the form of blocks. A feed can display news items, personal photos, or products.
The term 'feed' is often used in the context of social media, for instance on Instagram or Facebook. A feed is actually a representation of all the posts that someone makes.
Influencers make clever use of their feed by paying attention to the design, for example. Beautiful images, a catchy caption or authenticity are important when putting together an interesting feed. This allows you to create valuable content, which can ultimately lead to more engagement or brand awareness.
