Might that be a hierarchy (i.e. menu/link structure) issue?
Wouldn't have thought so - the "landing" page is linked via a big call-to-action button on the homepage, is a top-level link in our main navigation and appears throughout the site (but not site-wide) as part of the breadcrumbs.
Besides, I'd rather have the landing page rank as its cleaner and more focused, whereas the home page details our full range of activities.
