More about it:
Social media platforms often have algorithms that decide which posts are shown to users. These algorithms consider multiple factors, such as the user’s interests and the engagement a post receives.
A higher organic reach means more people are seeing the post without paid promotion, which can benefit brands and businesses looking to increase visibility and engagement without spending money on advertising.
