Topher Kohan presented on mobile-first design and Google's Accelerated Mobile Pages (AMP) project. He discussed how most sites are seeing growing mobile traffic and emphasized the importance of a consistent user experience across devices and connection speeds using the same URL. He noted that AMP can increase traffic, brand visibility and revenue for sites like weather.com by allowing content to load quickly on mobile and dominate search results for weather events. Kohan encouraged publishers to focus on serving users first with clean, optimized mobile content.
