I kid you not, I just had the following conversation:

Hey Mike, I've got a question for you about PPC tracking in (Overture) Console. Here's the situation: Someone clicks on one of our ads. They visit our site and write the website name down on a piece of paper. A few days later they decide to come back and they type the name into that place on the browser where the www is. Are we tracking those PPC hits?

Me: Just so I'm clear, you want to know if someone writes our URL down on a piece of paper after doing a PPC click then returns to our site by typing in the URL if the PPC tracking is getting it?

Yes

Me: Someone has written our URL down on a piece of paper and you want to know if it's being tracked by PPC.

Yes.

Me: Uh...no.
