Setting up scrapes for new listings by city or zip code helps me monitor real estate trends and see which areas are growing in popularity.

• By parsing eBay’s JSON responses directly from network requests, I can extract product details like price, seller ratings, and product ID.

• Setting up a schedule to scrape key financial metrics, such as PE ratio or dividend yield, helps monitor stock performance regularly.

• Requests and BeautifulSoup can extract static HTML content, while Selenium is ideal for handling TUI’s dynamic pricing and availability displays.

• Use Python’s Requests library to monitor network requests for JSON data, which often includes reviews and ratings, bypassing HTML parsing.

• Since Mercari uses AJAX for some dynamic content, I combine Nokogiri with Watir to handle content that loads after page interactions.

For dynamic content, like reviews and real-time stock information, Selenium with headless Chrome works well, especially when combined with randomized delays.

Axios or Fetch can be used for JSON data retrieval, especially if network requests expose structured product data.
