@gleitz perhaps using a headless browser like puppeteer or selenium might fix this problem? Not sure how it would affect performance, but might be worth looking into.

Hi @gleitz, I would like to contribute to resolving this issue;

• I have done some research and I think if we use some data scrapping python libraries like scrappy, beautifulsoap etc
• I can also use request-html along with selenium for better data rendering
• Another method that also came along the way of my research was by using API like SerpApi

Please do assign me this issue, I have already started working on it, having some issues while running howdoi in my local machine due to some python packages being broken while installation which will be resolved by today.
