Google Adds Soft Navigation Metrics to CrUX – What It Means for Local SEO

What Happened\nOn October 13, Chrome’s engineering team rolled out experimental soft‑navigation metrics to the Chrome User Experience Report (CrUX). These metrics capture in‑app page changes that bypass a full reload—a frequent pattern in single‑page applications (SPAs). Three new fields—experimental_largest_contentful_paint_with_softnavs, experimental_inp_with_softnavs, and experimental_cls_with_softnavs—are now available via BigQuery, the CrUX API, and the History API, and CrUX Vis includes a toggle to display them.\n\n## Key Details\n- **Soft navigation definition**: A visible change to the URL and a visible paint that occurs without a full reload.\n- **Coverage**: About 70 % of origins in CrUX have little or no soft navigation traffic, so many sites will see minimal impact. Sites built around SPAs are the ones that will notice a change.\n- **Data availability**: The metrics are already in BigQuery and the CrUX API; the Chrome browser has had the Soft Navigations API enabled by default since version 151.\n- **Experimental status**: Google plans to review the data in May 2027. If the results are positive, Search Console will adopt the new metrics once the experiment ends.\n- **Stable scores unchanged**: Current stable Core Web Vitals scores remain the same until the experimental data is finalized.\n\n## What It Means For Your Business\nLocal and small businesses that run SPAs or rely on client‑side routing will feel the impact of these new metrics on how search engines evaluate performance. Here’s how you can stay ahead:\n\n- **Audit your SPA**: Use CrUX Vis or BigQuery to pull the new soft‑nav fields for your domain. Identify pages that experience frequent soft navigations and see whether their LCP, INP, or CLS scores dip.\n- **Optimize client‑side routing**: Make sure navigation events trigger a full paint and that critical content loads quickly. Consider pre‑fetching resources for the next view.\n- **Improve user experience**: Soft navigation events can be smoother than full reloads, but if they cause layout shifts or input delays, they will hurt your metrics. Fixing these issues can also reduce bounce rates and improve conversion.\n- **Future‑proof your site**: When Google eventually adopts the experimental data into Search Console, sites that already track soft navigation performance will have a clearer picture of how their pages rank for AI‑driven queries.\n\n### Quick Checklist\n- Run `chrome://crux` or use the CrUX API to fetch soft‑nav data for your URLs.\n- Compare the experimental metrics against the stable ones.\n- Prioritize pages with high soft‑nav traffic for performance tuning.\n- Monitor changes after May 2027 to see how the new data affects rankings.\n\nWhy It Matters:\nPage load speed and user experience are key ranking signals. Soft navigation metrics give a more accurate picture of how a SPA performs during real user interactions, which AI tools like ChatGPT and Gemini use to surface relevant local listings. By monitoring and optimizing these metrics now, you can reduce bounce rates, improve conversion, and position your site as a trustworthy local resource for AI‑powered queries. Additionally, as AI tools increasingly pull data from the CrUX dataset to generate answers, having strong soft navigation performance can help your business appear in AI‑generated snippets and recommendations, giving you a competitive edge in local search visibility.
