Say, for example my company name was "bob smith tools" and amongst other things we sold widgets.
Say I submitted the mask URL www.widgets.com which masks my real domain name www.bob-smith-tools.com - would this improve ranking for widgets? Could I do the same for hammers ie. www.hammers.com masking www.bob-smith-tools.com? I would still have the generic www.bob-smith-tools.com on my headed notepaper and in the ranking too.
