Search engine optimization?

[enom]

On my site, i have some of the post ranked on pages 2,4,6,1,3,1 and two other post i cant even find what page there on for the main post keywords of the articles. First question is how can i improve on them to get page one ranking. Secondly when i log onto google profile and i search these same keywords, the short post linking to my site that i create in google pluse usually comes up on page 1 of google when i do a search for the keywords but then i am logged off google plus, i dont see those google plus short post listed again. Why is this?
By the way the site is at http://getmymoneyout.com thanks in advance.
