TL;DR

Google’s featured-snippets page answered 200; we did not log a SERP box for any query.

Direct answer: A featured snippet checker records titled documentation plus an empty capture column until you store a query. On 2026-09-14, https://developers.google.com/search/docs/appearance/featured-snippets answered HTTP 200 (29,207 bytes; H1 “Featured snippets and your website”). The snippet-control page also answered 200. No search query was issued. The sample size is two docs URLs and zero boxes. The desk phrase seo featured snippets still names that same packet.

A featured snippet checker slide that fills the capture column from a guessed query is already mixing two jobs. Eligibility copy is not a result page.

Read indexation signals on one URL before you rewrite for a box.

What you will learn

• Why Google has no official featured snippet checker
• Why Rich Results Test and title previews are different products
• Which Search Central URLs we actually fetched
• Why a docs H1 is not a featured box
• Which fields a later SERP row still needs
• When nosnippet is policy, not a ranking lever

What is a featured snippet checker?

A featured snippet checker is a way to record whether Google showed a position-zero extract for a stored query, locale, and device. Google does not ship an official featured snippet checker. The Rich Results Test reads structured data so you can see which rich results that markup can generate. That is not a featured box.

The planning phrase seo featured snippets on this desk stays the docs-then-empty-column job: fetch the featured-snippets URL, fetch snippet controls, leave the SERP column blank until a reviewer stores the extract. A featured snippet checker that treats those 200s as “we won” is inventing a field.

A title-and-meta preview is a different product. The SEO title checker owns title and meta preview. A featured snippet checker that draws pixel-wide <title> bars is already on the wrong page.

Do not paste a detector login, a question generator, or a live Search scrape into this URL. Those are other products. This featured snippet checker only refuses a win-rate slide until a capture exists.

What the documentation fetch recorded

Key definition: A featured snippet checker on this desk is one featured-snippets URL × one snippet-control URL × one empty SERP column. The older label seo featured snippets names that same packet. A box counts only when a later reviewer stores query, locale, device, and the displayed extract. A FAQ entity is not that box.

People open a featured snippet checker after a teammate pastes a paragraph and writes “this should win.” That sentence is not a capture. Start with the public docs responses. Write both H1s, or write “H1 not parsed.”

The Google featured-snippet documentation is the page this desk fetched first. We stored status, bytes, and H1. We did not accept its screenshots as a substitute for a query we ran. That fetch starts a featured snippet checker; it does not fill the capture column.

SEO Health remains the deterministic evidence foundation for on-page lights on this URL. A later InfiniSynapse Server API long-task workspace may consume SSE /api/ai/events for an extractability brief; the API does not request a Search feature.

The unit is a documentation URL

The unit is the guidance page, not a results layout. seo featured snippets that copies a sample question from the docs into a “we won” column without a stored SERP is inventing a field.

The Google snippet documentation is the second 200. It explains ordinary result snippets and publisher controls. It is not a logged box.

What we did not query

No search query. No locale panel. No device class. No account state. seo featured snippets that hides those absences cannot be replayed.

As of 2026 this page is not a customer Search Console export.

Public pages we could fetch

User-agent InfiniSynapse-SH67-desk/2026-09-14.

Three titles parsed. Three HTTP 200s. Zero SERP boxes. A featured snippet checker still has no extract to code.

The Google robots meta specification defines nosnippet, max-snippet, and related controls. We kept the URL. We did not scrape a results page to see them applied. seo featured snippets does not inherit a box from that spec.

Figure: Every bar is a public docs page. None is a result box.

The featured-snippets H1

The H1 we stored is “Featured snippets and your website.” That string describes Google’s feature for site owners. seo featured snippets that relabels it as “box observed for query X” is changing the evidence class.

The Google supported meta tags lists supported page-level directives. It is not a SERP capture.

Why the capture column stays empty

A later Search job can fill query, locale, device, date, displayed extract, and a permitted screenshot. This packet leaves that column blank on purpose. Filling it from memory does not prove selection.

Google AI features guidance connects snippet eligibility language to AI search surfaces. We did not open AI Mode. Schema.org FAQPage defines FAQ entities. Markup does not assign a featured box.

How to reproduce the three 200s

curl -sS -A 'InfiniSynapse-SH67-desk/2026-09-14' -o /tmp/featured-snippets.html \
  -w '%{http_code} %{size_download}\n' \
  https://developers.google.com/search/docs/appearance/featured-snippets

curl -sS -A 'InfiniSynapse-SH67-desk/2026-09-14' -o /tmp/snippet-control.html \

Expect 200 unless Google moves the docs host. Store all three titles. Do not paste a blue-link screenshot under this chart. seo featured snippets reproduction stops at the public guides until a reviewer actually issues a query and keeps the capture offline.

MDN robots.txt glossary is a crawl-control primer. It is not a featured-box log. RFC 9309 is the robots protocol. It does not name a snippet winner.

CLI boundary on the same morning

seo-health eeat on https://infinisynapse.com/en/editorial-standards printed unauthorized after a page fetch. This snippets page did not spend that credit either. The command is not a Search query. seo featured snippets notes that quote scores[] without a taskId from a logged-in run are fiction.

Package pin infinitegrowth@0.1.1; -V printed 0.1.0. Record both.

A same-morning seo-health check on /en/tool/seo-title-checker exited 0 with 2,928 words and a missing-alt warning. That light is on-page HTML. It cannot establish a seo featured snippets win.

What a later Search pass must keep

When someone does run queries, freeze the exact question, locale, language, device, account state, and date. Hash the permitted capture. Save the displayed extract separately from the page’s visible answer. Leave “won” and “lost” unlabeled until a second reviewer sees the same box.

seo featured snippets fails when a regular snippet is coded as a featured box.

Visible answers versus selection

Identify the smallest visible block that answers the question. A paragraph, list, or table can all be extractable. Extractability is not selection. Google’s featured-snippets page says systems decide whether a page is a useful source. seo featured snippets that treats a short paragraph as a reserved slot is overstating the docs.

Bing Webmaster Guidelines are another engine’s public rules. They do not fill this empty Google column.

Publisher controls

Inspect nosnippet, max-snippet, and data-nosnippet on the page you own. A missing directive permits normal processing. It does not award a box. A restrictive directive may be legal policy. Removing it requires an owner, not a hoped-for feature.

W3C HTML validator documentation can check markup you actually fetched. It does not validate a result we never opened.

The sample size here is two documentation URLs and zero queries. That cannot establish a featured appearance, and it does not prove a paragraph edit caused a box.

Failure modes that invent a box

Docs 200 as a win. A guidance H1 is not “we were selected.”

FAQ schema as a switch. FAQPage describes entities.

Forty words as a threshold. Google publishes no exact minimum.

Meta description as the extract. Ordinary snippets and featured extracts are different jobs.

Memory as a SERP row. No query, no box.

Unauthorized CLI as invisibility. Login failed. Search was not asked.

A featured snippet checker memo that skips the empty-column rule is already late.

How a reviewer should read the log

Start with the three 200s. Confirm the featured-snippets H1 still says “Featured snippets and your website.” Confirm the control page still says it controls snippets. Confirm this article still shows an empty capture column. Only then issue a query, if the ticket actually needs one. A featured snippet checker that opens Search first will contaminate the record with whatever the reviewer already believed about the page.

Save the docs fetches before you change nosnippet. Changing controls can change what Google is allowed to use. seo featured snippets that deletes a directive first is measuring a policy edit, not the 2026-09-14 packet.

If the later SERP shows no box, keep the row. Zero is a result. Deleting quiet queries inflates the next “win rate.”

When the reviewer is done, the folder should contain: the three dated curls, the empty or filled capture column, and a one-page decision. The decision may be “no action,” “clarify the visible answer,” or “keep nosnippet.” seo featured snippets is not required to produce a traffic forecast.

Do not upload a full results screenshot to a public ticket to prove you worked if policy forbids it. Redact. Store a hash of the allowed extract. seo featured snippets that publishes raw SERP HTML to look empirical is leaking a session, not proving eligibility.

What stays on disk after this desk

Keep the three curl logs, the three H1 lines, and a one-sentence note that no query was issued. That folder is the 2026-09-14 featured snippet checker packet. If a later teammate adds SERP rows, they go in a dated subfolder with the query hash, not into this chart.

Print the package pin on the same page as the empty-capture note: infinitegrowth@0.1.1 and -V = 0.1.0. Those strings do not prove Search behavior. They prove which CLI we could have used and did not authorize against a query.

A reviewer who needs a punch list can still run seo-health check on a public URL they own. Expect on-page lights, not snippet bits. seo featured snippets does not promote those lights into a featured score.

If legal asks whether we “tested featured snippets,” the accurate answer is: we fetched three titled Google docs and we did not log a box.

Store the user-agent InfiniSynapse-SH67-desk/2026-09-14. A later browser UA can receive a different shell. Write the new status beside the old 200s.

The decision this page supports is narrow: refuse a win-rate slide until a query capture exists. seo featured snippets does not decide titles, schema flags, or budgets. Those decisions need the addendum folder.

When the addendum folder is still empty next quarter, republish the same three 200s with a new date if you re-fetched them. Do not backfill remembered boxes to make the quarter look complete. Empty is a legal state for a featured snippet checker. A quarter with three dated 200s and a still-empty capture column is a complete desk, not an unfinished slide.

Nearby guides

The SEO title checker owns the public <title> extraction and title and meta preview. Do not copy that table here. A featured snippet checker is not a pixel SERP simulator.

The on-page SEO tool hub still owns the broader eight-check story. A featured snippet checker stays on the docs-then-empty-column job. The planning phrase seo featured snippets still names this packet.

Frequently Asked Questions

What is a featured snippet checker?

A featured snippet checker records docs you can fetch plus a later SERP row you actually stored. Google has no official tool for it. Rich Results Test is schema. Title previews belong on the title checker. This page still has an empty capture column. The desk phrase seo featured snippets still names that packet.

Is the Rich Results Test a featured snippet checker?

No. The Rich Results Test reports which rich results structured data can generate. A featured snippet is a selected extract. seo featured snippets on this desk does not treat that test as a box.

Did we log a featured box for any query?

No. The desk fetched public pages. A featured snippet checker on this URL still has no extract to code.

Does FAQ markup assign the feature?

No. FAQPage describes question-and-answer entities. It does not assign seo featured snippets or guarantee a presentation.

What does nosnippet change?

It can prevent text snippets, including featured and regular extracts, for the page. Google also documents data-nosnippet and max-snippet. Permission is not selection.

How should a later SERP row be stored?

Save query, locale, device, date, source URL, displayed extract, and permitted evidence. Label it an observation. It cannot establish a permanent slot.

May we publish a win rate from this article’s chart?

No. The chart is HTTP 200 versus title present. It does not prove a box appeared.

Conclusion

Use a featured snippet checker when the job is to refuse a win-rate slide until a query capture can be stored. This 2026-09-14 seo featured snippets packet recorded three public 200s and zero boxes. Stop when the three H1s and the empty capture column remain visible. A bounded docs log beats an unsupported featured percentage.

Eligibility is a later Search job; this packet is three titled docs and an empty capture column.
