The company name appears first in the title tags and other places on the site. It's easy to forget that your corporate site will probably rank first in Google for your company name and brand names so there's probably no need to optimize for it.
It can be fixed by using keywords at the beginning of your title tags and moving your company name to the end. For example: 'Mortgages by Big Bank Corp' instead of 'Big Bank Corp Mortgages'. See Chapter 3, On-page Optimization
