What is the best way to find a better job, online, newspapers like alwaseet or by applying personally everywhere?

Internet and recruitment agencies

Online job sites like Bayt.com.
But also through your network of friends and colleagues.

I believe online or newspaper, but not Alwaseet, only specialized newspapers like the appointment.
Generally, these channels are used by serious employers and not spams, others involves spam jobs that are published for other motives.

Networking is the key, bayt.com, (URL removed due to policy violation. Please contact support for further information.), twitter are all means to the same goal.
