What is a People Also Ask tool?

A People Also Ask (PAA) tool extracts the questions Google shows in the 'People also ask' box for any given keyword. The Lumina PAA Research tool goes further by recursively expanding each question four levels deep via the DataForSEO serp/google/organic/live/advanced endpoint, returning a complete hierarchical tree of 10–50+ questions per keyword.

How do I extract People Also Ask questions for free?

Use the Lumina People Also Ask Research tool. Enter a keyword, select country and language, and click Extract PAAs. You get 15 free queries per day per IP address. No signup or credit card required. For unlimited access, add your own DataForSEO API key in Settings.

Is this a free AlsoAsked alternative?

Yes. Lumina PAA Research is a free alternative to AlsoAsked with additional features they don't offer: AI intent clustering, GEO-ready content brief generation with FAQ schema (JSON-LD), and Google AI Overview detection. AlsoAsked costs $12–47/month; Lumina is free for 15 queries/day.

What is the people_also_ask_click_depth parameter?

people_also_ask_click_depth is a DataForSEO SERP API parameter (values 1–4) that tells the API to simulate clicking PAA questions recursively. At depth 4 — the Lumina default — the API expands every visible question up to 4 levels deep, revealing the full question tree that would otherwise require dozens of manual clicks.

How the PAA Research tool works

Enter a keyword and this tool extracts the full Google People Also Ask tree via the DataForSEO serp/google/organic/live/advanced endpoint with people_also_ask_click_depth: 4 — four levels deep instead of the 3–4 questions you see on the initial SERP. Each node includes the question, answer snippet, source URL, and ranking domain. Related Searches and Google AI Overview detection are bundled for free in the same response. One-click AI Clustering (GPT-4.1-mini) groups questions by search intent, and the GEO Content Brief generator (GPT-4.1) turns them into a ready-to-write content structure with 134–167 word passages, an entity checklist, and FAQ schema (JSON-LD) you can paste straight into your CMS.

The tool targets 63 countries and 39 languages using DataForSEO location and language codes. It works as a free alternative to AlsoAsked, AnswerThePublic, and KeywordTool.io Questions — the key difference is that Lumina combines the real PAA tree with AI intent clustering and a GEO-ready content brief in one workflow, where the others focus only on visualization.

FAQ

What is the daily limit?+

15 free PAA queries per day per IP address. The AI features (clustering + GEO content brief) share a single 10/day AI quota. Alphabet Expansion has its own 100/day bucket because each click fires ~33 sub-requests. Enter your own DataForSEO and OpenAI API keys in Settings for unlimited access.

What is people_also_ask_click_depth?+

A DataForSEO parameter that simulates clicking PAA questions recursively. At depth 4 (our default), the API expands every visible question up to 4 levels deep — first the initial 3-4 questions, then each reveals more, and so on. This gives you a complete question tree, which would take dozens of manual clicks to reproduce.

Are these real Google PAAs or synthetic?+

100% real. The data comes directly from Google's SERP via DataForSEO's serp/google/organic/live/advanced endpoint. Unlike AnswerThePublic (which uses autocomplete), this tool extracts the actual People Also Ask box Google shows to real users in your selected country and language.

Why do some AI Overview questions have no answer?+

Google generates AI Overviews on-demand per session in the browser. DataForSEO flags these as asynchronous_ai_overview with no pre-rendered text or references. The question itself is still valuable for your content strategy — it tells you what Google considers important enough to surface as an AI Overview prompt.

What's included in the GEO Content Brief?+

(1) H2/H3 structure organized by cluster/topic; (2) 134-167 word passages per question (optimal for AI Overview citation); (3) FAQ Schema (ready-to-paste JSON-LD) with all questions and concise answers; (4) an entity checklist (named concepts to mention for topical depth); (5) citation hooks — specific stats, dates, or data points to include for GEO citability. Downloadable as Markdown (.md) and JSON (.json).

How is this different from AlsoAsked or AnswerThePublic?+

AlsoAsked shows the PAA tree but has no AI clustering, no GEO content brief, and no FAQ schema export. AnswerThePublic uses autocomplete suggestions (not real PAAs). This tool combines the real PAA tree with AI-powered intent clustering and a one-click GEO-ready content brief — all in one workflow.
