I will take example of this website
http://onestopslots.com/
see text in upper border portion starting with “I hope you’ll click to” in this border tag has nothing to do with SEO, but the text you placed in that which comes as common in all pages is the crawlers which index before the other portion of your page. If you see this website, i can say that you can make it very good with nice HTML tags and CSS which i will say 50% improvement from existing website
