More than half of US online, nonelderly, commercially insured consumers have visited their health plan's Web site last year. Once there, members avail themselves of an array of administrative tools like finding a doctor, checking a claim, and checking coverage.

To address the needs of site users, health plans need to develop a coordinated, cross-channel interaction strategy.
