Instagram statistics explained: This is what reach & impressions mean

For many people, Instagram statistics are their first contact with analytics - and often the first point of confusion. Numbers are there, arrows pointing up or down, but what does that actually mean? Is a lot of reach good? Are many impressions better? And why do the numbers never quite match the feeling? This article explains Instagram statistics in a deliberately dry, comparative way and without promises of optimization. No creator talk, no algorithm hack. Just meaning, differences and classification. Dead internet SEO, but correct.
