This is a phrase that an experienced person uses to suggest an action to the listener. When you say "You may want to consider ___ing", it's not a very strong suggestion. You're still letting the listener make the decision. But using this phrase does make it sound like you're knowledgeable on a topic. Some other examples:

If you're planning on remodeling or renovating your home this summer, you may want to consider hiring a contractor and architect.

If you work in a very physically or emotionally demanding job, you may want to consider starting your maternity leave before your due date.
