What Is Next After Completing Content Planning Sheet

Last year I started a blog which is now well-maintained, But now the content of that site is not left more, So Just want to know, In the content planning sheet should I make some changes or not, If Yes, Than what changes should I make in content planning sheet, As for rest similar web keywords than I covered it as well, And now I don’t have much keywords, Just suggest me what I do now…!
