I just did a quick analysis and it looks like your domain strength is low (DA 17) and you are trying to rank for moderately competitive keywords 30-40%
The only way you can rank for the keywords mentioned with that low of a domain strength is by AWESOME on-page-optimizations. Use the Term Target Tool tool to help with the process. Shoot for an "A" on each page and definitely have an exact match in your title tag. Currently your home page only has a grade of "C" for the term "federal auto loan" so there is room for improvement.
Keep focusing with your on-page, you have a sharp looking site so once you get traffic there you should be all set!
Good luck - Kyle
