How to Monitor Price Changes on Any Website

Price tracking is one of the most popular uses for website monitoring tools. Whether you're waiting for a sale on electronics, watching airfare prices, or tracking cryptocurrency exchanges, automated price monitoring can save you hours of manual checking.

Why Monitor Prices?

Prices on e-commerce websites change constantly. Studies show that Amazon alone changes prices millions of times per day. Without automated monitoring, you might miss:

Flash sales that last only hours
Price drops before items sell out
Seasonal discounts on expensive items
Price matching opportunities

Setting Up Price Monitoring

Step 1: Find the Price Element

Most websites display prices in a consistent location. Use your browser's developer tools (right-click → Inspect) to find the CSS selector for the price element.

Common price selectors include:

.price
#product-price
[data-price]
.sale-price

Step 2: Create Your Monitor

Add the product URL to PulseWatch

Enter the CSS selector for the price

Set your check frequency (every 5-60 minutes recommended for prices)

Enable notifications

Step 3: Set Up Keyword Alerts

For even more precise monitoring, use keyword filters:

Alert when price contains "$99" or less
Filter out "Out of Stock" notices
Watch for "Sale" or "Discount" keywords

Best Practices

Don't check too frequently - Every 15-30 minutes is usually sufficient for price changes

Monitor multiple retailers - Prices vary significantly between stores

Set realistic targets - Historical price data can help you set achievable target prices

Act quickly - Some deals are time-limited, so enable push notifications

Conclusion

Price monitoring automation takes the guesswork out of finding deals. Set it up once, and let the alerts come to you instead of constantly refreshing pages.
