Our website scores A but on google we are still on 7th page

Hi all, I have run on page keyword optimizations with exact terminology used to find our company service or our competition on google. We have ranked A, with almost all points complete. I did the same for our main competitor and they ranked F. Then i did page positioning on Google and they get on page 1 fifth line and we get page 7.  We have plenty of unique content and extensive website.
Could there be any other reason than reason for this other than backlinks?

Many thanks for your help.

There could be many, many reasons for this other than back links.  Could you provide your URL so we can take a look?

what url are you testing to get an A? and I assume this is using the SEOMoz tool for on page optimisation?

There could be many many reasons you don't rank above your competitor, from links to age, to authority and even quality of content. among other reasons....

Optimization is only a small part of ranking well in with SEO. Think of it as a piece of a larger pie.  Use the open site explorer tool to understand your backlinks against your competitors and the keyword analysis tool as well. This will give you a better overall picture of why you are not ranking better.

Lastly, i understand where you are coming from. it's really seductive to get crazy about page optimization, but all the page optimization in the world isn't going to compare to a bunch of high quality, really great links with anchor text.
