Web Scraping for SEO: Extract People Also Ask Questions at Scale

Google's "People Also Ask" (PAA) boxes are a goldmine for SEO. They reveal exactly what questions your audience is asking — and answering them is one of the fastest paths to featured snippets and increased organic traffic.

What is People Also Ask?

People Also Ask is a SERP feature that displays related questions and expandable answers for a given search query. Key characteristics:

  • Appears in 75%+ of search results
  • Each expanded question reveals 2-4 more questions
  • Questions are dynamically generated based on search intent
  • PAA results often overlap across related keywords

Why PAA Data is Valuable for SEO

Content Gap Discovery

PAA questions reveal topics your audience cares about that you might not be covering:

Query: "RAG pipeline"
PAA Questions:
  - What is a RAG pipeline?
  - How do you build a RAG pipeline from scratch?
  - What is the difference between RAG and fine-tuning?
  - What are the best vector databases for RAG?

Each question is a potential blog post, FAQ entry, or content section.

Featured Snippet Targeting

PAA answers are essentially featured snippets. If you can provide a better answer than what's currently shown, you can win that spot. The format Google prefers:

  • Definitions: 40-60 word paragraph
  • Lists: 4-8 items with brief descriptions
  • Tables: Structured comparisons
  • Steps: Numbered how-to instructions

Search Intent Mapping

PAA questions help you understand the full journey of a searcher:

  • Informational: "What is..." → Educational content
  • Comparative: "What's the difference between..." → Comparison guides
  • How-to: "How do you..." → Tutorials and guides
  • Commercial: "What is the best..." → Product reviews and recommendations

Extracting PAA at Scale

Using link.sc Search API

import linksc

client = linksc.Client(api_key="lsc_...")

def extract_paa(keyword: str) -> list:
    """Extract People Also Ask questions for a keyword."""
    results = client.search(
        q=keyword,
        format="json"
    )
    return results.people_also_ask or []

# Extract PAA for a list of seed keywords
seed_keywords = [
    "web scraping API",
    "LLM data pipeline",
    "RAG architecture",
    "AI web crawling",
]

all_questions = {}
for keyword in seed_keywords:
    questions = extract_paa(keyword)
    for q in questions:
        all_questions[q.question] = {
            "answer": q.answer,
            "source_keyword": keyword
        }

print(f"Found {len(all_questions)} unique PAA questions")

Building a PAA Database

import json
from datetime import datetime

def build_paa_database(keywords: list, output_file: str):
    """Build a comprehensive PAA database from seed keywords."""
    database = []
    seen_questions = set()

    for keyword in keywords:
        questions = extract_paa(keyword)
        for q in questions:
            if q.question not in seen_questions:
                seen_questions.add(q.question)
                database.append({
                    "question": q.question,
                    "answer": q.answer,
                    "source_keyword": keyword,
                    "extracted_at": datetime.now().isoformat()
                })

    with open(output_file, 'w') as f:
        json.dump(database, f, indent=2)

    return database

Analyzing PAA Data

Clustering Questions by Topic

Group related questions to identify content themes:

from collections import defaultdict

def cluster_by_intent(questions: list) -> dict:
    """Cluster PAA questions by search intent."""
    clusters = defaultdict(list)

    for q in questions:
        text = q["question"].lower()
        if text.startswith(("what is", "what are", "what does")):
            clusters["definitional"].append(q)
        elif text.startswith(("how to", "how do", "how can")):
            clusters["how-to"].append(q)
        elif "vs" in text or "difference" in text or "compare" in text:
            clusters["comparison"].append(q)
        elif text.startswith(("best", "top", "which")):
            clusters["commercial"].append(q)
        else:
            clusters["other"].append(q)

    return dict(clusters)

Prioritizing Content Opportunities

Score questions by content opportunity:

  1. Not yet answered on your site (high priority)
  2. Related to your core product/service (high priority)
  3. High search volume keyword (medium priority)
  4. Low competition in current PAA answers (high priority)
  5. Already answered on your site (low priority — optimize existing)

Monitoring PAA Changes

PAA results change over time as Google updates its understanding. Set up monitoring:

def monitor_paa_changes(keywords: list, previous_data: dict):
    """Detect changes in PAA results."""
    changes = []

    for keyword in keywords:
        current = extract_paa(keyword)
        previous = previous_data.get(keyword, [])

        current_questions = {q.question for q in current}
        previous_questions = set(previous)

        new_questions = current_questions - previous_questions
        removed_questions = previous_questions - current_questions

        if new_questions or removed_questions:
            changes.append({
                "keyword": keyword,
                "new": list(new_questions),
                "removed": list(removed_questions)
            })

    return changes
