monitor particular word appearance Bewertet mit 3 von 5 Sternen

is it possible to look for changes if particular word will appear on site? i am not interested with changes that are not related with specific word. If my page is changed and my word appeared than I'd like to be notified. I can monitor activity of other users on pages. Regards
