If you're an aspiring novelist or creative nonfiction writer, I'd seriously advise against posting advertising or Adsense on your website. This type of thing cheapens the author's branding and his/her platform. (I used to work as a copy editor and social media manager for a literary agency and I don't recall any of our award-winning writers having ads on their websites unless you count links from their books to Amazon.) I just checked out the websites of a few of my favourite authors: Mary Karr, Paul Auster, Pico Iyer.....no, none of them have trashy ads cluttering up their professional pages.
