Let's take an illustration of various processors as with their independent caches of sharing the same memory system.
Now when this memory is a Read-Write memory and let's as that one of the processors writes to such memory after several data computation, all the processors require updating their individual cache copies of the here modified memory. To perform this concept of snooping is implemented. Therefore, Cache snooping is the means by that each cache constantly monitors/detects the bus for any write to a memory location and when a write is found, this invalidates it current copy of cached memory data and copies the latest content over.
