Data Sources Explained#

Google PAA (People Also Ask)#

Uses people-also-ask Python library to scrape "People also ask" questions from Google. Works without API key. May need proxy rotation for heavy use.

Google Autocomplete#

Queries Google's suggestion API endpoint. Returns related searches. Free but rate-limited.

Reddit#

Uses Reddit's public JSON API. Searches relevant subreddits for user discussions, pain points, and questions. Great for understanding real user needs.

Bing Search#

Bing has less aggressive bot detection than Google. Good for related searches and content ideas.

Tips for Better Results#

1. Use multiple seed keywords for broader coverage
2. Combine sources for comprehensive data
3. Filter results by relevance to your niche
4. Use clusters to identify content gaps
5. Reddit data is gold for understanding pain points

Known Limitations#

• Google may block requests from data center IPs
• Reddit API may require authentication for heavy use
• Results quality depends on seed keyword specificity
• Rate limiting may slow down large research jobs
