How do I get a better insight into what determines the ads Google displays on a given page. How would you rank the importance of the following 1) meta keywords 2) meta description 3) words in headers - h1, h2, h3 etc 4) words in anchor text of hyperlinks 5) words in bold 6) the appearance of a given word multiple times (keyword density) 7) the appearance of words near the top of the next, front of meta description, first word in headers etc (keyword weight) Sometimes I look at the ads Google displays and shake my head...I cant understand it.
