Notice the differences. The capacitor values, define the lower end of the frequency response. Usually the higher the capacitance the better, but not too high too, because it'll delay the biasing settling, and it's not practical. There arw formulas, but here we have a bode plot with which you can check if they cover your requirements. The second major difference is that the bias chain (the two base resistors) are not taken from Vcc but from the collector. This stabilises the transistor from thermal drift and is always beneficial. The feedback here is not very strong, so the drift is not well compensated, but you get the idea. I've put a bunch of negative feedbacks, here and there, you can ignore them if you want.
