If I am adding this text to a page : (php,asp,aspx,cgi,perl,etc) then will search engines (Google/Yahoo/MSN) be able to understand that I am refering to a big keyword : (php,asp,aspx,cgi,perl,etc) , but rather I am refering to keyword[1] : php keyword[2] : asp keyword[3] : aspx keyword[4] : cgi keyword[5] : perl ?! I mean will search engines will automaticaly change (for example) : (romania) to romania ?! What about (romania,danube) ?! Will it be automaticaly changed by google/msn/yahoo to romania and danube ?
