@JM, this is scary.
Do you loose constantly old keys or other, jet not touched, keys take the way down ?
I see cicles of uppopping keys in a 4 weeks turn. They stay one to three days and then they are gone to make place for a new keyword.
Always to have the same amount of traffic a day.
Googles internet world gets smaller, itīs a very itelligent way of make the user used to have less choices. In one or two years google will make money only by showing 5 domains and poeple are lucky.
Plus, they donīt have to invest in new storage hardware. Nice new internet world.
