Target Audience

This workflow is ideal for:
- Content Managers who need to monitor changes on webpages, such as Terms of Service or privacy policies, to stay compliant.
- Digital Marketers who want to track competitor websites for updates and changes in offerings or messaging.

Problem Solved

This workflow addresses the challenge of manually tracking changes on webpages. It automates the following:
- Continuous Monitoring: Automatically checks a specified webpage at scheduled intervals.
- Change Detection: Utilizes hashing to detect content changes, ensuring users are only notified of significant updates.
- Documentation: Automatically logs changes in Google Sheets and stores snapshots in Google Drive for future reference.

Workflow Steps

  • Scheduled Trigger: The workflow initiates based on a predefined schedule, ensuring regular checks on the specified webpage.
    2. Variables Setup: The URL of the webpage to be monitored is defined, allowing easy updates.
    3. Fetch Webpage: An HTTP request node retrieves the current content of the webpage.
    4. Extract Contents: The relevant content is extracted using HTML selectors, focusing on the specific information to monitor.
    5. Hash Generation: A hash of the extracted content is created to facilitate change detection.
    6. Remove Duplicates: The workflow checks if the generated hash is new or has been seen before, preventing unnecessary notifications.
    7. Snapshot Creation: If a change is detected, the current content is saved as a text file in Google Drive.
    8. Log Changes: The details of the change, including the hash, change date, and a link to the Google Drive file, are logged in a Google Sheet.
    9. Email Notification: An email is sent to notify the user of the detected change, providing all relevant details.
