9. Social media analysis provides a
potential way of seeing:
• Which bits of sites are popular with people
• How people respond to changes in sites
• What customers are interested in outside
the site
• Showing public value, from interest in the
site among non-visitors
• But, limitations, a self-selecting sample and
behaviour may not be representative

10. Conclusions
• Big Data’s growth will give the Visitor Economy
more information about its customers, and
hence a greater ability to target its offer
• However, obtaining and interpreting the data
may require specialist skills, and important to
respect privacy
• New data sources likely to supplement, and
lead to evolution in, existing data sources such
as surveys
