I wondered how you found anything with on only 19 results in Google. I was afraid you were looking at things wrong.
creatine is far from being non-competitive and has 8.4 million competing pages in Google.
Even allintitle: creatine which is the better indicator of competition has 307,000 competing pages.
Where did you come up with 19???
OOOOOPPPPPS Sorry, I got it now.
When you said: QUOTE: "For example pros and cons of creatine" I thought you were asking us what the pros and cons orf optimizing for a term like creatine were. I see now you must have searched for "allintitle: pros and cons of creatine". Sorry!
