When a page is slow, static assets fail, caching looks wrong, or too many third-party scripts are present, check asset health first, then static cache policy, HTTP cache/CDN headers, compression, script governance, and finally security headers and CSP.

Common lookup scenarios
Find broken or redirected CSS, JS, image, and font assets
Review Cache-Control, ETag, Age, CDN signals, and immutable caching
Check gzip or brotli compression for HTML, CSS, and JavaScript
Inspect third-party script origins, render blocking, SRI, and supply-chain risk
Check whether analytics, ad, support, and AI-related tags are excessive or blocking before release
Recommended workflow
- Audit page asset health for broken resources and size issues
- Check long-cache policy for fingerprinted static assets
- Review HTTP cache and CDN response clues
- Review analytics, ad, support, and AI-related scripts before release
- Carry third-party script findings into CSP and security-header checks before release
- Finish with compression, origin-exposure, and response-policy checks

LookupToolChakanFAQ
When a page is slow, static assets fail, caching looks wrong, or too many third-party scripts are present, check asset health first, then static cache policy, HTTP cache/CDN headers, compression, script governance, and finally security headers and CSP.
Does this replace Lighthouse?
No. These tools inspect public response, asset, and script signals quickly. Full performance scoring still needs Lighthouse, real-user data, and CDN reports.
Why audit cache and third-party scripts together?
Slow pages are not only server problems. Cache misses, weak static caching, blocking scripts, third-party supply chains, and security headers all affect UX and crawl reliability.
