  • Introduction

    • Vercel has implemented automatic mitigation of Google and Bing crawl delay through Skew Protection. This enhancement helps prevent indexing failures that can occur when there is a delay between document crawl and asset download.

  • Skew Protection Extension

    • The maximum age for Skew Protection has been extended to 60 days for requests from major search engine bots like Googlebot and Bingbot. This ensures that assets deployed up to 60 days ago will still be accessible to search engines during rendering.

  • Automatic Protection

    • Pro and Enterprise accounts using Skew Protection will automatically benefit from the extended 60-day protection, regardless of the configured maximum age in the dashboard. This automatic protection helps improve SEO by safeguarding against indexing failures due to render delays.

  • Learn More and Enable

    • Users are encouraged to learn more about Skew Protection and enable it in their projects to take advantage of this automatic mitigation feature. By doing so, they can ensure that their websites are better optimized for search engine crawling and indexing.
