How you get your job alerts determines whether you are first in the queue or last in the pile. Choose wisely.
Speed isn't everything. If you set up a raw RSS feed for a popular term like "Graphic Design", you will get spammed with hundreds of low-quality posts every hour. You will eventually ignore the notifications.
