My advice: Seek and find a trusted professional who can take care of this for you. Is your site in English?

My other advice: Improve English. Search more for this stuff, you actually need to read and learn a lot for the answers you are seeking. That is not a question anyone can give you a good answer to around here in one piece.

Once you do more research, you find out that there are tools out there such as https://ubersuggest.io/ and google keyword planner for ads that help you get the answers you want related to keywords. but best advice for YOU is to hire a professional in my humble opinion.
