Re: how to put my own keywords
Unfortunately your question is a but unclear to me. Would it be possible to rephrase it and give some more background information?
(a) "how can i put my own keywords to google analytics"
For an example... are you talking about Meta Keywords for SEO purposes?
(b) "and how can check specific visior on my website ?"
Tracking a specific IP address, is as far as I know not possible in Google Analytics due to privacy issues.
