What signals indicate a topic is trending today?

Signals of a trending topic

A trending topic shows fast-growing attention and visibility across sources. Look for spikes in engagement, sudden increases in mentions, and top posts reaching wide audiences.

Common signals include:

• Rapid rise in shares, comments, and saves.
• Multiple posts or outlets covering the same subject.
• High activity in a short time window (minutes to hours).

Also check the diversity of sources: if both mainstream outlets and social users are discussing it, it's likely a genuine trend rather than an isolated spike driven by one account.
