Engagement rate doesn't measure how many people find you interesting. It measures how many, among those who saw you, did something more than scroll past — a lower bar than it sounds.
“A post generating a hundred passive reactions and a post generating ten comments from decision-makers in your industry have the same engagement rate and completely different value.”
Otto GTM ObservatoryEngagement rate typically aggregates very different interaction types (reactions, comments, shares, clicks) into a single number, treating them as equivalent. In a B2B context, a comment from a relevant industry decision-maker is strategically worth much more than dozens of passive reactions from a generic audience, but standard engagement rate calculation doesn't make this distinction.
A qualitative analysis of who generates the engagement (role, company, industry), not just the aggregate volume, allows distinguishing content that generates surface-level visibility from content that generates conversations with the audience actually relevant to the business.
Common mistake: optimizing content to maximize aggregate engagement rate, rewarding divisive or polarizing topics that generate many interactions but from an audience not relevant to the brand's positioning.
Second mistake: comparing engagement rate across different platforms (LinkedIn, X, Instagram) as if they measured the same thing, when interaction definitions and distribution algorithms are structurally different.
A company publishes a polarizing post on a current topic that generates an 8.2% engagement rate, the highest ever recorded on the page. Analyzing the profiles of those who interacted, only 4% belong to the target audience (C-level roles at B2B companies): the next, more technical and less viral post generates a 2.1% engagement rate but with 61% of interactions coming from the target audience, generating 3 direct contact requests versus zero from the viral post.
