Python’s ease of use and broad library support make it accessible, especially for beginners. However, if performance is a priority, C# with HtmlAgilityPack is a strong contender, especially if you’re targeting Windows environments.

If the site is built with React or Vue, there’s a good chance data is loaded via API calls. I look for these in the page’s JavaScript code or in the dev tools.

If the data loads incrementally (like with infinite scroll), I use JavaScript event listeners to detect new content, then scrape the page once all content has loaded.

Product pages often have specific tags or indicators for availability, like “In Stock” or “Out of Stock.” I locate these using CSS selectors or XPath expressions.
