About this tool
Review image delivery exports before release so critical assets stay on approved CDN hosts, avoid insecure protocol regressions, and preserve predictable caching behavior.
This SEO tool is built for pre-publish QA and implementation support rather than vague optimization advice. It helps teams check one search-facing signal cleanly before a page, template, or release goes live.
- Parses rows in URL|image-url|status|cache-control|provider|context|bytes format and normalizes relative image paths with an optional base URL.
- Flags hosts outside your configured CDN allowlist, non-CDN provider rows, and HTTP image URLs that can break secure rendering baselines.
- Surfaces weak cache-control directives, redirect/error status risks, and page-level critical non-CDN byte overflow to prioritize high-impact fixes.
