Successful business bloggers pay close attention to

A) delivering new information quickly.
B) choosing topics of peak interest to audiences.
C) communicating in a personal style,with an authentic voice.
D) all of the above.

Successful business bloggers should pay close attention to all three factors - delivering new information quickly, choosing topics of peak interest to audiences, and communicating in a personal style with an authentic voice. They need to constantly update their blog with fresh and relevant content, select topics that their target audience is interested in, and use a writing style, which is personal and authentic to build a strong connection with their readers. Focusing on any one factor while ignoring the others can result in an unbalanced approach, which may not be as effective in achieving the desired results.
