why does my site not appear in some searches

Hi Everybody, i have recently started a Motor trade Job board called Motor Trade Vacancies and have been adding content and updating my Meta words on a daily basis (i am new to this so any help or advise is always welcome), If i Google search "Motor trade vacancies" i am at the top of page 2, however, if i google "Motor trade jobs" i am nowhere to be seen. I was told to add "Motor trade jobs" to my content and meta words which i have done but still do not show anywhere. Is there something else i should try?
