Brian Hawkins discussed trends in optimization and segmentation discovery. Some key trends include using data-driven test decisions, coordinating testing with other marketing efforts, and conducting geo-targeted tests. Segment discovery on a website can enable better media buys for display and paid search by identifying valuable customer segments. Going forward, there will be more automation, use of authenticated and third-party data, deeper testing integrations, a focus on mobile and apps, and continued application of onsite learnings offline.
