After seeing a few people's threads on keyword research, most of them state that profitable keywords usually have around 1000 local monthly searches or more, and out of those they usually use anything that has a CPC value of 1.00 or higher. My question is, what does this all mean in terms of profitability? Is there an equation that I can use to determine that? Is it good to have a high CPC value (over $1)? Is it good to have a high LMS value (over 1000)? And what would having those high values mean? Thanks in advance.
