Building a 24/7 Competitor Monitoring System

Every business needs to track competitors. But manual checking is time-consuming and inconsistent.

The Problem

• Competitor pricing changes overnight
• New features launch without notice
• Market shifts happen fast
• Manual monitoring doesn't scale

The Solution

Automated monitoring that never sleeps:

class CompetitorMonitor {
  async checkPricing(url) {
    const page = await browser.newPage();
    await page.goto(url);

    const price = await page.$eval('.price', el => el.textContent);

    if (price !== lastPrice) {
      sendAlert(`Price changed: ${lastPrice} → ${price}`);
    }
  }
}

What It Monitors

1. Pricing Changes - Track competitor prices hourly
2. Feature Updates - Detect new product launches
3. Content Changes - Monitor blog posts and announcements
4. SEO Shifts - Track keyword rankings
