FAQ

Q: Which e-commerce sites are supported? A: Amazon is the primary optimized target. For other e-commerce sites, the Actor uses JSON-LD structured data (schema.org Product/Offer), Open Graph meta tags, and generic HTML pattern matching. Sites using standard structured data markup work best.

Q: How reliable is price extraction? A: JSON-LD source (shown in priceSource field) is most reliable. Sites without structured data fall back to regex patterns. If price: null is returned, the site may require a browser-based scraper or has dynamic pricing loaded via JavaScript.

Q: Can I monitor JavaScript-heavy sites (SPA)? A: This Actor fetches plain HTML without JavaScript execution. Sites that load prices via JavaScript after page load may not return accurate prices. For those, use Apify's Playwright-based Actors.

Q: How do I set up price drop notifications? A: In your Apify run settings, go to "Integrations" and add a webhook. Configure it to trigger on run completion. Use the dataset results to check for priceAlert: true items and route to Slack, email, or Zapier.

Q: Can I track historical prices? A: Schedule daily runs and store results in Apify Storage. Each run creates a timestamped dataset. Connect to Google Sheets for a free price history chart.
