I don't understand something simple. Hopefully someone here can help. The null-to-null bandwidth of the main lobe of a BPSK signal is twice the symbol rate. 

BPSK transmits one bit per symbol, so the signal bandwidth is twice the bit rate. 

That has been shown on a few stack overflow questions. This implies the spectral efficiency is 0.5 bits/second/Hz. 

However, a quick Google for the spectral efficiency of BPSK gives an answer of 1 bits/second/Hz. Why?
