Related searches scraping, answered

How do related searches differ from autocomplete suggestions?+

Autocomplete predicts as you type; related searches show how users reformulated after seeing results — post-SERP intent. For content planning, related searches are the stronger signal: they tell you what the current results failed to answer.

How do I build a keyword graph from this?+

Seed with your head term, collect its related searches, then re-query each suggestion recursively. Two or three hops out from one seed typically maps an entire topic cluster. At 3 credits per SERP call, a 200-node crawl costs well under a dollar.

Do related searches vary by location and device?+

Yes — Google localizes reformulations ("standing desk ikea" vs local retailer brands) and mobile often surfaces different suggestion sets. Use `country`, `location`/`uule`, and `device` to sample each market you care about.

Is this the same as People Also Search For (PASF)?+

No. Related searches is the block at the bottom of the SERP; People Also Search For attaches alternative queries to individual organic results. Both are returned by the same endpoint — PASF-style entity data also appears in the knowledge graph element as `peopleAlsoSearchFor`.

What else comes back in the same call?+

Everything on the SERP: organic results, sponsored ads, People Also Ask, shopping cards, and optional AI Overview enrichment.

Map your topic clusters from real SERPs

Related searches ship free with every SERP call — from $0.40 per 1,000.
