How do I schedule crawls to revisit pages every day?

To schedule crawls to revisit pages every day, you generally want to set up a recurring crawl schedule or a crawler job that runs daily. The exact steps depend on the crawler/tool you’re using, but the common approaches are:

If your crawler has built-in scheduling

1. Open the crawl/project settings.
2. Look for Schedule, Recurrence, or Automation.
3. Set it to run daily.
4. Choose the time of day and timezone.
5. Save and enable the schedule.

If you’re using a script or custom crawler

Use a scheduler like:

• cron on Linux/macOS
• Task Scheduler on Windows
• Cloud schedulers like:
  • AWS EventBridge
  • Google Cloud Scheduler
  • Azure Scheduler / Logic Apps

Example with cron:

0 2 * * * /usr/bin/python3 /path/to/crawler.py

This runs every day at 2:00 AM.

If you want only certain pages revisited daily

• Keep a list of URLs to recrawl.
• Use a queue with a “last crawled” timestamp.
• Re-enqueue pages when they become due.
• Respect robots.txt and rate limits.

Best practices

• Add incremental crawling so you only fetch pages that changed.
• Use ETag / Last-Modified headers if available.
• Avoid crawling too frequently if the site changes slowly.
• Monitor failures and retries.
