Of all the aspects of brand management that are important but undervalued, brand architecture must surely top every marketer’s list. Most companies have more than one brand, but an amazing proportion of firms rarely give enough thought to how many of them should actually exist and the manner in which these brands should, or should not, be combined or kept apart when presented to customers.

This singular suite of offerings should now work together in a more seamless and customer-focused way. Google now has just one brand to track, position, sell, protect and grow.

Google’s move away from multiple brands and towards a single branded-house approach is evidence of the more general trend in marketing towards operating fewer brands.
