  • What’s the best way to handle date-based scraping for historical data?

    Building date parameters into URLs lets me scrape historical data efficiently. This works well on sites with consistent URL structures for archives.

    For sites with date filters, I automate date selection in the form or URL parameters to scrape data for specific periods.

    Some websites offer date-range APIs, which are far more efficient for historical data than scraping HTML. I always check for these before starting.

    I use a database to track which dates have been scraped, so I don’t duplicate efforts or miss any dates.

    Automating navigation of pagination and date filters is helpful, especially on news or financial sites where archives are extensive.

    For sites with complex date filtering, I set up a schedule to scrape in batches. This approach reduces load on both my system and the target site.

    Using Selenium’s calendar selector works well when scraping sites with graphical date pickers. I simulate clicks to pull data by day, month, or year.

    When scraping extensive archives, it’s important to respect rate limits to avoid IP bans. Slowing down the scraper reduces the chance of getting blocked.
