For sellers of every kind, consumer data is more available then ever before. That, as most of us know, is the good news. The bad news? Most sellers have no idea how to connect these data points. If prospect John Doe researches their product online, posts about it on Facebook to crowd-source opinions from friends and then uses his mobile phone to do a price comparison, most retailers don't know how to connect all these data points to serve John better. Making this connection means thinking about services and sales support in a new way. Here are for quick tips to change your thinking: Be systematic about which data you track, focus only on the most important data, fill in data holes by purchase or partnership and, finally, match the data with the consumer.
