Is it possible to track when a website blog posts a new article and have the article automatically scraped?

It is indeed possible. We have an action called 'When a website changes' that checks the website every 10 minutes for any changes (within the scraped area). If there are changes, it will scrape whatever you ask it to scrap and can either send you the results via Slack or update a Google Sheet. Here's a post that explains how this action works : (https://community.bardeen.ai/t/get-new-youtube-comment-notification-on-slack-from-a-youtube-video-link/246/2).
