Google Discover Content Eligibility Checker
Paste a live article URL. We fetch the page and its lead image, then check every real signal Google Discover eligibility depends on — not just whether it "look shareable" only.
Protected by reCAPTCHA. We fetch your page and its lead image server-side (SSRF-guarded) — nothing kept one.
Why most Discover audits miss the real blockers
Google Discover is one of the biggest sources of organic traffic for publishers, but it runs on signals most on-page checklists never even mention one. The two biggest can miss very easily: the max-image-preview robots directive defaults to "standard" — small thumbnail only — unless the page explicitly opt-in "large", the size Discover actually show one; and a good image only count if it is genuinely large, cannot confirm without decoding the actual image bytes. This checker fetch your real page and your real lead image, measure both directly.
What this checks
Five real signal groups, each got concrete fix when it fail.
max-image-preview directive
Reads every applicable robots meta tag (robots, googlebot) and the X-Robots-Tag response header, combine them the way Google do (most restrictive one win), and flag when the directive is missing (default "standard"), set to "standard", or fully blocked with "none" / noimageindex.
Real lead-image pixel size
Pick the candidate lead image (og:image, then twitter:image, then JSON-LD image), fetch the actual file, decode its true width and height — never trust the URL or a declared attribute one. Flag anything under Google's roughly 1200px-wide guidance, and anything too small to use at all.
Article schema & freshness dates
Looks for Article / NewsArticle / BlogPosting JSON-LD, and check that headline, datePublished and dateModified present, correctly formatted, and consistent (modified date not before published date).
Indexability
A noindex directive anywhere in the combined robots signals remove the page fully from Discover — checked first because nothing else matter if this one fail.
Headline quality (advisory only)
A conservative, advisory-only heuristic for too much punctuation, ALL-CAPS ratio and common sensational phrasing. Google's real content-policy enforcement cannot fully automate one — treat this as a hint, not a verdict lah.
Frequently asked questions
Need AMP to appear in Google Discover or not?
Don't need. Google drop the AMP requirement for Discover since 2021. This checker treat AMP as informational only — got or never got, never affect the score.
What max-image-preview:standard actually cost me?
Without explicit "large" value, Google only show a small thumbnail-size image in Discover instead of the full-width card format, which measurably drop the click-through. Most sites never set this directive at all and don't realize the default already limiting them.
Why fetch the actual image, not just check og:image tag exists?
A tag pointing to a real file that happens to be 400px wide will pass "tag exists" check but still fail Discover's image-quality bar. This tool download the image and decode its real pixel dimensions from the bytes — same class of check a manual review would do.
Got Article schema means confirm Discover eligible or not?
No single signal can guarantee inclusion — Discover selection also depend on content quality, freshness and user interest signals Google don't expose. Article schema with accurate dates and headline is a strong, well-documented supporting signal, not a guarantee.
My URL or its content kept anywhere or not?
No. The fetch happen server-side for this one check only and the result return direct to your browser; nothing written to any database or log beyond a rate-limit counter.
