What this tool does
Preload Link Checker inventories preload hrefs, as types, file types, crossorigin attributes, missing href values, missing as attributes, and font preload crossorigin reminders from pasted HTML.
Common use cases
Check pasted HTML head snippets for rel=preload resource hints before performance QA, template review, or launch handoff.
Use Preload Link Checker during a pasted-input SEO QA pass before publishing or handing off a page. It helps review copied metadata, snippets, headings, social tags, or canonical signals without crawling a live URL.
How to use it
- Paste preload link tags, an HTML head snippet, or copied build output.
- Review the preload count, resource types, href values, file types, and warnings.
- Pair the result with stylesheet, script, favicon, and canonical checks before publishing.
Example workflow
Paste the relevant title, description, tag block, heading outline, or canonical markup from your draft page. Review the warnings and preview output, make edits in your CMS or document, then recheck the same pasted input before publishing.
