The power of social media from a marketing standpoint, informally

FREEPR

Think of what brands get when their posts go viral—no ads, just organic buzz.

This clue plays on the idea that social media gives brands exposure without traditional ad costs, which marketers often call "free publicity" or "free PR." The answer shortens that phrase to "FREEPR," blending the financial perk ("free") with the marketing term ("PR"). The "informally" hint signals the casual, abbreviated style of the answer.
