Reach shows how many people see your content, while engagement shows who reacts. Both matter, but they serve different purposes. High reach without engagement means many views but little interest. Strong engagement with low reach means fewer people but deeper attention. Platforms often reward engagement by pushing content further. For brands, engagement helps build trust and real connection, not just numbers. Reach helps awareness, while engagement helps growth and feedback. A balance between both brings better results over time. It also guides future content and posting choices today clearly. Which do you think matters more when measuring success online?
