Doing SEO when using location is not an option

[questfore]

When doing SEO for a company that does not have a specific location (they are an online-only retailer), and doesn't want their manufacturing location given, what is some advice on other great SEO tactics that will help counter the disadvantages of not using anything location-related (Google Places, directory submissions, etc). Obviously backlinking and on-page optimization, but in regards to the fact that Google is becoming more and more encouraging of sites that are location-optimized and listed in many records such as Places, Yelp, directories, etc., does anyone have any advice?

I would go deep into Content Marketing and Social Media (aka: inbound marketing). If it doesn't want to show its location, hence not use the local search and geotargeted search opportunities, the only way is to become a really listened voice in its market area.
