Related Searches

Related Searches is a Google SERP feature that displays thematically related query phrases at the bottom of search results.

In the semantic audit pipeline, Related Searches serves as the second source (alongside PAA) of real user data for query expansion; it's tagged as SERP-ONLY in the SERP Grounding system. The difference between PAA and Related Searches: PAA contains questions (question format), Related Searches contains phrases (keyword format). Both complement each other and provide a fuller picture of intent. Related Searches often reveal query variants that LLM won't generate — for example, local variations ('inheritance claim Krakow'), comparisons ('inheritance claim vs vindication clause'), or specific amounts.

In semantic crawling, Related Searches are collected automatically via Bright Data or a scraper. In practice, collect Related Searches for EVERY seed query and EVERY sub-query. This exponentially expands the keyword base without additional LLM cost.
