One issue companies face is to communicate with specific groups of consumers, but to keep this discrete from other groups who may view the information as  confusing or even as a negative positioning for the brand.

A good example of this is Alpro,  who has created a good on-line resource for  people who think they might need to avoid lactose or go dairy free, without presenting the brand as medicinal or pseudo-medicinal to the general public- who are only just coming to terms with Alpro as a mainstream choice.

By using a “segmented gateway” to the Alpro Lactose free pages, http://www.alpro.com/uk/lactose-dairy-free  only those vistors who have specifically searched for lactose or dairy free, (or been directed from a relevant site) will see the resource. Visitors who enter via the home page or recipe pages will not normally see this content (unless they have previously visited it).
