Puppeteer and Playwright can simulate scrolling or clicking on “load more” buttons to capture all messages in longer comment threads.

I automate pagination and set delays to avoid hitting rate limits, which is especially important on sites that monitor frequent requests.

Some tooltips are loaded as separate AJAX requests, so inspecting network requests while hovering often reveals endpoints for the data.

Regular expressions can sometimes capture patterns within unconventional tags, though it’s less reliable for deeply nested data.

For sites like Amazon, I capture product variations by scraping dropdown menus or variant selection fields to pull options for size, color, etc.
