As far as I know, this is the most common method and the aim is to use the miller capacitance to move the poles to stabilize the op amp. It is however not necessarily about the first and the second stage.
Simple miller compensation suffer from weak PSRR. So usually current buffer or voltage buffer approaches are used. There are many different techniques u can read about them:
For 2 stage u can use:
1) dominant pole compensation
2) parallel compensation
3) simple miller compensation
4) simple miller compensation with zero nulling resistor
5) simple miller compensation with current buffer (cascode compensation)
6) simple miller compensation with voltage buffer
7) multipath miller zero cancelation
8) feedforward and others
