How do you handle pagination when scraping websites?

For sites using AJAX to load more content, monitor the network tab for API calls and replicate them.

If the page uses infinite scrolling, Selenium or Playwright can simulate scrolling.

I typically inspect the pagination structure to see if there’s a predictable pattern in the URL (e.g., page=2). I then increment the page number until there’s no more data, which stops the script when all pages are scraped.

Many times, sites have hidden pagination APIs that power the ‘next’ button. Inspect the network requests to see if there’s a JSON endpoint or similar. You can then scrape the JSON directly, skipping HTML parsing altogether.

For infinite scrolling, I use Selenium to simulate scrolling, waiting for new data to load each time. You can control the scroll rate and set timeouts to ensure all items are loaded.

Scrapy’s pagination support is helpful if you’re using that framework. It can auto-detect pagination links based on your rules, which reduces custom coding, and it stops when no next link is found.
