How this service works
Prüft am Objekt seite den Befund Zahl renderblockierender Ressourcen.
Output
Returns a performance finding for the target page indicating the number of render-blocking resources (scripts, stylesheets, etc.) detected that block the browser's rendering pipeline, allowing developers to prioritize optimization efforts.
Example use cases
Pre-launch performance audit
“Before we go live, check https://staging.myshop.com for render-blocking resources so I know if anything is going to delay the page from loading.”
SEO and Core Web Vitals investigation
“Our Google Search Console is flagging slow page speed — can you check https://www.myblog.com/article/seo-tips for render-blocking resources and tell me how many there are?”
Continuous monitoring for performance regressions
“After the last deploy, check https://app.mybusiness.com/dashboard for render-blocking resources and let me know if the count has gone up compared to before.”

Endpoint

Choose this endpoint when you specifically need to audit a web page for render-blocking resources as part of a performance or Core Web Vitals investigation. It is distinct from sibling endpoints that measure time-to-first-byte, first contentful paint, or resource counts for other asset types like scripts, images, or iframes.
Side effects
- Invalid or unreachable URL returns an error or empty finding
- Non-public URLs (e.g. localhost, intranet) will fail to load
- CSS selector matching no element may fall back to first match or return error
- Malformed input schema (missing 'ziel' field) triggers validation error
- Timeout if the target page takes too long to respond
