I wanted to know a few things about keywords. Lets say i have a webhosting site based in India. I have to set my website's meta keywords. (1) What are the optimal number of keywords per page i should use ? (2) Are, web host india, one keyword or a keyphrase ? And how many such keyphrases / keywords i should use per page ? (3) Are these keywords different, web host india, india web host ? (4) Are these keywords different webhost india, india webhost ? (5) Someone told me to use googlekeywordtoolexternal for analyzing the keywords based on competition, monthly searches, CPC etc. like someone suggested, choose the one with medium level of competition, $1 + CPC & 2000 monthly searches. Is that optimal ? I just can't understand this keyword concept. Can someone help me out here ?
