How do I get awarded with the best answer on yahoo?

Find a question you feel you can contribute a thoughtful response to.

Keep it brief.

Double check your grammar and punctuation because, in my opinion, it shows you care about the readers.

Avoid insults and name calling unless you are being intentionally humorous.

My best advice? Try giving your best answer without expecting a reward.

The Asker Picks your Answer as the Best as far as what you have to do you have to Post a Good Answer and just hope that the Asker Ends up picking yours as the Best

You give a good, detailed answer to the question you're responding to, so that the asker may find it helpful. After that, it's up to the question asker to decide which, if any, answer they liked best. The majority of questions on the site never have a BA selected (it's not required).

answer a question and if someone likes it you may get best answer award

You provide what the poster considers to be the best answer. From my perspective it seems obvious.

when you ask a question you get to choose the best answer.
