How to automatically estimate search volume for “People Also Ask” question keywords?

I’m collecting question-based long-tail keywords from the “People Also Ask” section in Google (actually also for those, which I just brainstormed), such as:

• “How to increase site speed in WordPress?”
• “Why is my WordPress site so slow?”
• “What is the best plugin to speed up WordPress site?”

I want to understand whether particular question has any search volume. How to automate this process of extracting the essential root keyword (e.g. from the above examples → increase WordPress site speed, WordPress slow site, WordPress speed plugin). In this case I can automatically check the volume then,

What are the most reliable methods or tools you use for this? Any tips on workflows or libraries for automating this would be appreciated.

Although probably not fully accurate tools like answer the public or answer Socrates will be worth a look.

Use Keywords everywhere, it'll show up on a bar on the right of your screen

Semrush got a filter for questions as part of its keyword research tool (keyword magic tool),
You don't need to rely on Google PPA for that

Combine PAA extraction with Google Trends to see interest over time for each keyword.

You can make this process automatic by using keyword extraction and search volume APIs together. First, use NLP libraries like spaCy or KeyBERT to get the main phrase from question-based keywords by getting rid of stopwords like "how," "why," and "what." After that, use tools like Ahrefs API, Semrush API, or Google Ads Keyword Planner API to get the search volume automatically by putting in the cleaned keywords. A simple Python pipeline that uses BeautifulSoup to scrape "People Also Ask," spaCy to clean, and one of those APIs to look up volume works well for workflows.
