I would love my webpage to show up on google searches when using a certain keyword (not in the advertisement space), but i also don't want to change anything visible on the page. is there anything i can do?

i love my webpage as is. under certain search terms, it is the top hit. under other very relevant search terms, i can’t find it anywhere in the hits. i love the current layout of the webpage, so i don’t want to change anything that impacts the use of the page. i could add text in white, or something like that. are there other ideas of simple stuff i could do? many thanks, and much love….
