Which of the following represents a broad match keyword?

Wall art" without any modifiers represents a broad match keyword. This means your ad could show for searches that include misspellings, synonyms, related searches, and other relevant variations. For example, your ad might appear for "pictures for walls," "artwork," or "posters." "“Wall art”" (with quotation marks) is a phrase match keyword, meaning the search query must include "wall art" in that exact order, though other words can appear before or after. "Wall +art" uses a broad match modifier (the plus sign), which requires both "wall" and "art" to be present in the search query, but not necessarily in that order or next to each other. "-wall art" (with a minus sign) is a negative keyword, which prevents your ad from showing for searches that include "wall art.
