I think you may have misinterpreted the license. There's no pay-per-view.

From the description:

"It is also available in web font formats for self hosted websites (up to 10K monthly pageviews on average)."

You buy a license for your website. Large websites (with more than 10k monthly pageviews) need to contact them for a license.

How do you know what the average page views will be when you buy it? How do you measure a page view?

For a blog or newspaper it may be obvious, for web applications it can be very hard to determine.

You might not know up front, for sure. I know when I load our website, I see a "transferring data from hello.myfonts.net" in the status bar, which I guess some sort of phone-home mechanism. If we go over the limit, I assume they'll notify us.

It's rather a simple algorithm:

1. Do I average more than 10k page views a month right now?

No: Buy license good up to 10k page views per month. Yes: Contact them about a bigger license.

You're not asking how to measure your own page views, are you?
