Description

I wanted a system to monitor website content changes and notify me. So I made it using n8n.

Especially my competitor blogs. I wanted to know how often they are posting new articles. (I used their sitemap.xml file) (The below workflow may vary)

In the Below example, I used HackerNews for example.

Explanation:

First HTTP Request node crawls the webpage and grabs the website source code
Then wait for x minutes
Again, HTTP Node crawls the webpage
If Node compares both results are equal if anything is changed. It’ll go to the false branch and notify me in telegram.

Sample Response:
