I bought some cheap traffic and pointed it to one of my parked pages.
What a mistake.
I had completely forgotton that it is against T&C's for most if not all parking companies.
The name got blocked by Google as a parking name. It had not produced fake clicks or anything. No increase in revenue. Just higher visitor numbers.
Then it was de-indexed by Google, so I lost visitors.
Not one of my smartest moves.
