Pinterest rewards clarity over cleverness

Because people search Pinterest the way they search Google, pin titles and descriptions work best when they stay clear and keyword-rich, with emoji used to add a visual accent rather than replace the actual words someone is searching for.

Emoji that suit Pinterest's aesthetic

Sparkles, a pin or heart, and category-relevant icons (a fork and knife for recipes, a house for home decor) tend to fit Pinterest's clean, aspirational visual style better than slang-heavy or face emoji.

Where to place them

A single emoji at the start or end of a pin title draws the eye in a scrolling feed without disrupting the searchable keywords in the middle of the title — stacking several emoji together tends to look cluttered against Pinterest's minimal card design.

Boards and descriptions

In board names and descriptions, one relevant emoji can help a board stand out in a user's profile grid, but the board name itself should still lead with the actual topic for search purposes.
