Automatic mitigation of Google and Bing crawl delay via Skew Protection
Vercel's Skew Protection now automatically extends asset availability to 60 days for search engine bots like Googlebot and Bingbot, preventing indexing failures when websites are re-deployed between crawl and render. This applies automatically to Pro and Enterprise accounts to improve SEO.
Google and Bing web crawlers occasionally crawl a document, but render it up to several weeks later using a headless browser. This delay between document crawl and assets download (which happens during render) can cause indexing failures if the website has been re-deployed since the crawl.
for projects that have enabled.Vercel now automatically protects against such indexing failuresSkew Protection
This was achieved by extending the maximum age for Skew Protection to 60 days for requests coming from major search engine bots, such as Googlebot and Bingbot. This means that assets deployed up to 60 days ago will still be accessible to search engines when they render your document.
Regardless of the maximum age configured in the dashboard, Pro and Enterprise accounts using Skew Protection will automatically be protected from this delay, thereby improving SEO.
