How to check the presence of the necessary content on thousands of pages?

Question

Computer networks

Good afternoon
The task is to check the presence of certain phrases, keywords on thousands of URLs. We need a simple software for Windows, where we will drive a list of URL - keys and it will check all of them in a cycle.
What do you advise?
Thanks
