People think about size all the time. Or maybe, we should call it word count.
Whether we're talking article, sales letter or blog post, people ask: How long should it be?
I've got the ultimate answer to that question.
Think about length in another way. Imagine that you're building a bridge across a river.
How many meters or miles should that bridge be?
The answer is: Long enough to bridge the gap between the two sides.
That goes for a blog post as well. You need exactly as many words as it takes to go from the introduction to the conclusion.
