In my experience, yes.

I know this for sure, because one prospect contacted me and said:

You don’t know me, but I’ve been following your blog for some time. And, having seen what you’ve written about various topics, and how you interact with your readers, I’ve formed the opinion that we can do business together.

She was right.

And it sure beat the crap out of me cold-calling her.

Such explicit blogging-for-business wins are rare.

To the intense frustration of old-school marketing types, it’s very hard to calculate return on investment for social media.
