Ranking categories

7 rankings across 3 groups (Entertainment, Brands & Campaigns, and People & Communities), all built on the same SII index system.

Methodology

The SII index combines 5 measurement components, normalized to a 0–100 scale.

5 components → 1 index

0100

  1. SOURCE BREADTH

    Source breadth

    The number of independent sources (personal profiles, fan pages, groups, channels, news sites…) that post about the entity during the period; each source counts only once.

  2. VIRALITY

    Virality

    How far and how effectively content spreads: shares, reposts, quotes, duets, stitches and equivalent forms of redistribution.

  3. POST MENTIONS

    Post volume

    The number of posts and articles containing a valid keyword or hashtag after context filtering; comments are not counted.

  4. CONVERSATION

    Comment volume

    Total comments under valid posts, reflecting how much conversation surrounds the entity.

  5. SENTIMENT

    Sentiment

    The share of positive / neutral / negative posts, as classified by AI.

The SII index is aggregated and normalized from its component indices under an independent measurement methodology.
