Ping vs HTTP vs Keyword Monitoring: What's the Difference?

Not all website checks are created equal. To build a robust monitoring strategy, you need to understand the different layers of website testing.

Ping Monitoring (Network Level)

Ping sends an ICMP packet to your server. It only verifies that your server is connected to the internet. It does not guarantee your web server (Apache/Nginx) is running.

HTTP/HTTPS Monitoring (Application Level)

This check requests a webpage and waits for a "200 OK" status code. It confirms your web server is active, but it won't tell you if your database crashed and the page is blank.

Keyword and XPath Monitoring (Content Level)

The ultimate check. It scans the actual HTML returned by the server to verify that specific content exists. This guarantees the page is not only loading but displaying correctly.
