Your next questions
More detail to help you decide what to do next.
Why do my posts have likes but no Explore reach?
Without saves, shares, and high retention, the algorithm confines distribution to existing followers.
How do I calculate true engagement rate?
Divide total interactions (likes + comments + saves) by reach or follower count.
How do Saves and Shares factor into 2026 Social SEO and search discovery?
Audio keywords, on-screen text, and save rates combine to drive modern semantic search ranking.
Separate measurement, advice and commercial services.
Meta describes likes, comments, saves, and other actions as signals whose likelihood Instagram predicts for Feed ranking; Meta does not publish one fixed universal weighting.
Compare one clearly labelled formula over a defined period, and separate content formats and organic from paid distribution.
BoostMaus offers visible likes, views, comments, saves, and reposts for supported public content.
Additional interactions do not guarantee Explore placement, virality, recommendation eligibility, sales, or organic growth, and they do not replace organic Insights.
