Google’s March 2026 core update is rolling out with mixed signals impressions clicks and rankings no longer move together possibly due to AI search layers
Google has begun rolling out its March 2026 core update, with the rollout expected to take up to two weeks to complete.
As with most broad core updates, early volatility is expected. However, initial signals suggest that this update may be harder to interpret than usual.
Several site owners are reporting mixed performance patterns, where rankings, impressions, and clicks do not appear to move in sync. In some cases, visibility remains stable while clicks fluctuate, while in others, ranking shifts do not translate into proportional traffic changes.
This type of divergence is not entirely new, but it appears more pronounced in the current environment.
One possible factor is the growing influence of AI-driven elements within search results. AI Overviews and other answer-based features are increasingly present across queries and can change how users interact with results.
Industry data already shows that AI-generated summaries can reduce click-through rates significantly, even when rankings remain stable.
In parallel, broader research suggests that a large portion of searches now end without a click, reinforcing the idea that visibility is no longer tied directly to traffic.
This creates a more complex environment for interpreting SEO performance during a core update. Traditionally, ranking changes were a primary signal. Today, they are only part of a larger system that includes AI-generated answers, entity understanding, and evolving SERP layouts.
It also means that short-term reactions during the rollout may be even less reliable than usual. Google has not provided new specific guidance for this update, reinforcing the idea that fundamentals still apply.
For now, the best approach is to monitor segmented data closely, particularly by query type, intent, and device. Informational queries may behave differently from transactional ones, especially where AI answers are more prominent.
It is still early in the rollout, and more stable patterns will likely emerge once the update completes. Until then, these initial signals suggest that SEO performance is increasingly shaped by multiple overlapping systems rather than a single ranking framework.
