Is considered as a eyword spamming if I a wrote as KEYWORD as K E Y W O R D , with additional space between letters?! for example : R E C O M M E N D E D
It depends where you put it. Add it 10,000 times to a page and it is spamming. Search engines won't read it as a word though.
That's what I thought. I checked it though, and it is counted as a keyword in google! Anyhow, back to the original question: anything you repeat too often will be considered spamming.
