Altruism is just any kind of selfless helping of others. The "effective" part means thinking about how to do more good with limited resources; ie does a marginal dollar spent on cancer research do as much good as a dollar spent on malaria control.
Not everyone wants to do the math themselves so there's some communication involved in sharing that research.
And as with any cause, outreach can be very productive as well. Unless you're so wealthy that you think you can solve the world's problems all by yourself, you might find it worthwhile to spend some time on advocacy.
