How to Monitor Any Website for Changes

Keeping track of changes on websites you care about can be exhausting. Whether you're watching competitor prices, job postings, product availability, or regulatory updates, manually checking pages wastes hours every week.

Website change monitoring tools solve this by automatically checking pages on a schedule and alerting you when something changes. In this guide, we'll show you how to set it up in under a minute.

Why Monitor Websites for Changes?

Here are common use cases where website monitoring saves time:

• Price tracking — Get notified when a product's price drops or a competitor changes their pricing
• Job boards — Know instantly when new positions are posted on company career pages
• Stock availability — Get alerts when out-of-stock products become available again
• News and regulations — Track government websites, news outlets, or industry publications for updates
• Competitor analysis — Monitor competitor landing pages, feature lists, or blog posts for changes

How to Set Up Website Monitoring with Pulse

Step 1: Create a Free Account

Head to pulsepage.dev and sign up. No credit card required — the free plan includes 3 monitors with hourly checks.

Step 2: Add a URL to Monitor

Click "New Monitor" from your dashboard and paste the URL of the page you want to track. Pulse loads the page in a real browser, so you see exactly what visitors see — including JavaScript-rendered content.

Step 3: Select What to Track

Use the visual selector to click on the specific element you want to monitor. This could be a price, a heading, a paragraph, or any other element on the page. You don't need to know CSS or HTML — just point and click.

Step 4: Configure Alerts

Choose how often you want Pulse to check the page (from every minute to every 24 hours, depending on your plan). Then set up your notification channels:

• Email — included on all plans
• Slack — connect your workspace for team notifications
• Discord — send alerts to any channel
• Telegram — get notifications on your phone instantly
• Microsoft Teams — perfect for enterprise workflows
• Webhooks — integrate with any tool via HTTP callbacks

Step 5: You're Done

Pulse checks the page on your schedule and sends you a notification whenever the content changes. You can view the exact diff of what changed, when it changed, and how it looked before and after.

Advanced Features

AI Smart Filter

Not every change matters. The AI Smart Filter (available on Pro plans) analyzes each change and only alerts you on meaningful updates — filtering out noise like timestamp changes, ad rotations, or minor formatting tweaks.

CSS Selector Monitoring

For power users, you can specify exact CSS selectors to monitor specific parts of a page. This is useful when you only care about a particular section, like a price table or an availability badge.

JavaScript-Rendered Pages

Many modern websites load content dynamically with JavaScript. Pulse uses a real Chrome browser engine to render pages, so it captures content that simple HTTP requests would miss.
