What job websites, job apps or methods to get a job are the best to use to find Entry level jobs consistently?

I have been looking for a nice job to move out for awhile now and I’m worried that if I lost my job that it would take forever to find another one if I were fired, hated working there or something else. I have no idea what websites are successful and what websites are not so if anyone could provide this information I would really appreciate it.
