Run multiple keywords with Search Engine Result

Hello, I want to run multiple keywords with Search Engine Result like. Example: 10,000 keywords. I see each setting as 1 keyword, so it takes a lot of time to install. Second problem, I want to insert keywords in content template. Example: <h2>Questions about %%keyword%%</h2> Please tell me the syntax to display keywords in body/title. Looking forward to hearing from you. Thank you!
