Is the AMP Test Tool enough to ensure your pages are indexed by Google?

What is the actual scope of the AMP Test Tool?

The AMP Test Tool focuses on validating the syntax of the AMP code — approved tags, required attributes, valid AMP script. It detects blocking errors like unauthorized JavaScript or incorrectly converted standard HTML tags.

This technical validation remains superficial. The tool does not verify if Google is actually indexing the page, if it appears in Top Stories carousels, or if it benefits from AMP caching. It's a linter, not an indexing diagnostic.

Why does this distinction between validation and indexing matter?

A perfectly compliant AMP code can fail to be indexed for third-party reasons: noindex tag, blocked robots.txt, canonical pointing elsewhere, or detected duplicate content. The AMP Test Tool does not report any of these barriers.

Conversely, pages with minor AMP warnings may index without issue if Google deems the content relevant and the errors non-critical. Technical validation is just an initial filter — not a golden ticket.

What tools complement the AMP Test Tool for a complete diagnosis?

To validate actual indexing, Search Console is indispensable. The AMP report indicates errors encountered during crawling, pages indexed in AMP, and blocking issues detected by Googlebot.

URL inspection allows you to force a live test and verify if Google can access the AMP version, which canonical URL it retains, and if the page is eligible for rich results. Server logs then confirm the actual visits of Googlebot on the AMP URLs.

• AMP Test Tool: syntax validation of the code, detection of HTML/JavaScript errors
• Search Console: actual indexing, errors on Google's side, discovered AMP pages
• URL Inspection: live testing, crawlability diagnostics, eligibility for carousels
• Server Logs: confirmation of Googlebot crawls on AMP URLs
• AMP Cache: check that Google caches the AMP version (test via google.com/amp/s/...)

Is this statement consistent with observed practices in the field?

The distinction made by Google is technically accurate but misleading in its phrasing. Practitioners often confuse AMP validation with indexing because Google has long communicated the importance of valid AMP code for accessing Top Stories carousels.

In practice, we regularly observe perfectly compliant AMP pages that never get indexed in AMP — Google prefers the classic desktop version. The reverse is also true: pages with AMP warnings display without issue in rich results. Technical validation is a necessary condition but far from sufficient. [To be verified]: Google does not publish any metrics on the correlation rate between AMP compliance and actual indexing.

What are the undocumented limits of the AMP Test Tool?

The AMP Test Tool ignores several critical dimensions for indexing: it does not simulate the crawl budget allocated to your domain, does not check prioritization directives in the sitemap, and does not test the actual loading speed from the AMP cache.

More problematic: it does not detect canonical conflicts between the AMP version and the desktop version. If your AMP page points to itself in canonical while the desktop points elsewhere, the tool remains silent — but Google will probably ignore the AMP version. These inconsistencies only show up in Search Console, often with several days of delay.

In what cases does AMP validation not guarantee any indexing?

If your site lacks authority or if the content is considered thin by Google, a flawless AMP code will not change anything. Google can crawl the page, technically validate it, then decide not to index it for qualitative reasons — and the AMP Test Tool will say nothing about it.

Sites under algorithmic penalty (Helpful Content Update, detected spam) have their AMP pages technically validated but excluded from rich results. The test tool does not report any signals on these qualitative filters. Let's be honest: technical validation is the bare minimum, not a guaranteed entry ticket.

How can you check if your AMP pages are actually indexed by Google?

Start with an audit in Search Console: AMP report for critical errors, Coverage report for actual indexing. Filter on AMP URLs and look for those marked “Detected, currently not indexed” or “Crawled, currently not indexed” — they pass the technical validation, but Google refuses to index them.

Next, manually test in Google using site:yourdomain.com/amp/specific-url. If the page does not appear even though it is validated by the AMP Test Tool, it's a clear signal of intentional exclusion by Google. Also check the AMP cache by consulting google.com/amp/s/yourdomain.com/amp/url.

What mistakes should be avoided during AMP validation?

Do not settle for a “Valid AMP” in the test tool. Ensure that the canonical of the AMP page correctly points to the corresponding desktop version, and that the desktop version links back to the AMP via rel="amphtml". A mismatch between these two directives creates an orphan in indexing.

Avoid submitting AMP pages in the sitemap without checking that they are accessible to Googlebot. If the robots.txt blocks the path /amp/, the AMP Test Tool will validate the code, but Google will never crawl the URLs. Always test the server-side rendering before submission.

What strategy should be adopted to maximize the indexing of AMP pages?

Prioritize pages with high informational potential for AMP — news, guides, tutorials. Google favors these formats in carousels. Commercial or transactional pages in AMP rarely bring measurable indexing gains.

Monitor the crawl rate of AMP URLs in server logs. If Googlebot visits your desktop pages but systematically ignores the AMP versions, it's a signal of disinterest — no point in continuing to invest time in maintaining AMP code. And this is where it gets tricky: these cross-diagnostic efforts require time and specialized expertise. If your team lacks the resources to continuously monitor AMP indexing, consider delegating to a specialized SEO agency that can automate these checks and quickly correct inconsistencies before they impact your traffic.

• Validate the AMP code with the Google test tool
• Check real indexing in Search Console (AMP report + Coverage)
• Manually test display via site: and the AMP cache
• Ensure the consistency of canonicals between AMP and desktop
• Analyze server logs to confirm Googlebot crawls on AMP URLs
• Monitor exclusions “Crawled, not indexed” specific to AMP pages
