This checker analyzes the raw HTML — fetched or pasted — it can't measure page speed, mobile rendering, backlinks or index status, and JavaScript-injected content won't appear in the source either way. Use it as an on-page hygiene check, not a full audit. Fetch-by-URL routes through a same-origin proxy; paste mode always works with zero setup. Tool provided free by ThrillSEO.
