My VA seems fairly slow with her article output; it normally takes her 1.5-2 hours for a single 500 word article. Even with 30 minutes of research (I would guess 15-20 is more accurate) it seems too long for a 500 word article.
But I could be wrong. For those of you who write articles, what do you think is a fair time range for writing an article? (exclude research if it's easier that way)
