Google is moving its JSON files listing IP ranges from /search/apis/ipranges/ to a more general location at /crawling/ipranges/ on developers.google.com. The files will remain accessible at the old path temporarily, but users are encouraged to switch to the new location soon. The old URLs will be phased out and redirected within six months.

Googlebot is part of a centralized crawling platform for various Google products, not a single crawler. It fetches up to 2MB per URL (64MB for PDFs), including headers, ignoring bytes beyond this limit. Linked resources are fetched separately with their own limits. The Web Rendering Service processes fetched bytes, running JavaScript and CSS but works statelessly. To optimize, keep HTML lean, place key elements early, and monitor server response times.

Chrome DevTools introduces CPU throttling calibration to improve performance debugging using real-world data. This feature allows developers to create low-tier and mid-tier CPU throttling presets specific to their machines, addressing performance discrepancies between desktop and mobile devices. While CPU throttling effectively simulates mobile performance, it cannot replicate all hardware aspects, particularly GPU tasks.

Google announced improvements to search speed via the Speculation Rules API, enhancing user experience by prefetching and prerendering results. It now prefetches the first two search results while ensuring privacy with features like anonymous IP usage. Tests showed significant loading time reductions. Prefetching extends to more results when users hover over links. Currently available on Chrome and Edge, Google aims for broader adoption and future enhancements.

A migration guide is available for transitioning to DevTools, and instructions for keeping a local copy of the extension are provided for those who cannot migrate. Google will continue to improve the Performance panel's features.

Google has updated PageSpeed Insights (PSI) to enhance visibility into the data collection period for Chrome User Experience Report (CrUX) metrics. PSI now shows CrUX data for the 75th percentile of real user visits over a 28-day period with a two-day delay. This update helps developers monitor site optimization impacts and affects Google search rankings. The implementation of CrUX data varies across Google's tools, improving accessibility for developers.

Google released a document on best practices for faceted navigation, addressing SEO challenges. While it enhances user experience, it generates numerous URLs, leading to overcrawling and delayed content discovery. Each filter combination creates distinct URLs, complicating SEO. Google suggests two strategies: blocking non-essential URLs with robots.txt and optimizing URLs with standard separators and consistent filter order.

Google's crawling infrastructure has seen a decrease in cacheable requests, dropping from 0.026% to 0.017% over the past decade. Caching is essential for fast page loads, resource savings, and bandwidth efficiency. Google supports heuristic HTTP caching through ETag and Last-Modified headers, with ETag being the recommended option for reliability. Implementing caching can save server resources and improve user experience, especially for sites with static content.
