2024 was heralded as the inaugural year of AI search, but we have now entered a new phase where AI-powered search has become the norm. Like navigating turbulent waters, success requires mastering the currents of change. This month, Google has made significant updates to its AI Mode functionality while the 2025 Google Search Central Asia Pacific conference delivered crucial insights.
