Definition PAA blocks summarize content that answers extra user questions. Opening each box links to a source page. PAA answers are selected by a variant of the featured snippet algorithm.
How it works When a user searches, Google analyzes query intent and selects boxes from a pool of related questions. Each box opens additional questions, and this expansion behavior grows the PAA pool. An opened box shows a 1-3 sentence summary and source URL. The chance of selection rises when the source page's relevant section is structured with H2, H3, or p tags.
Where you see it in Scope Trends The **SERP Features** report tracks PAA presence on your queries and whether you are the source. **Brief Producer** appends PAA question suggestions to every brief.
Frequently asked questions **Need FAQ schema to appear in PAA?** Not required. Google picks PAA content without schema. Schema strengthens the signal.
**How are PAA clicks measured?** Search Console reports PAA clicks as normal organic clicks; no separate breakdown exists.
