Adwords billing information

what do you put as "business type"?

[fom2001uk]

I'm just completing the billing info for an Adwords campaign. The form asks about "business type" with 2 options - B2B and B2C.

What am I supposed to put in here? I'm not a business, so I can't relate it to me. Or is it the business type of the client I'm running the ad for?

It's all a bit confusing.

I would have thought that it would be for your client's business. Whatever you put it shouldn't affect your campaign at all.

b2c = cheap flights to end user
b2b = industrial machinery

make sense?
