Site owners can narrow a homepage-only Google index by checking index coverage, crawl access and site quality separately. John Mueller said the reported pattern might reflect a general quality issue, but the available information does not establish a site-wide diagnosis.
What Happened
According to Search Engine Roundtable on November 3, 2026, John Mueller responded to a question about a site that had been hacked the previous year, then cleaned up, but was left with only its homepage indexed. Mueller said the pattern could indicate a general site quality issue and might be unrelated to the hack unless the compromise lasted for many months.
Mueller also noted that overlapping events, such as a hack and a core update, can make the cause difficult to identify. He said incomplete security cleanup and technical problems were other possibilities.
Are You Affected?
The pattern applies to a website that was previously indexed across multiple pages but now appears in Google Search with only its homepage listed. In the reported case, Google Search Console was not crawling the site’s internal links or indexing its other pages.
Site owners can review the indexed pages report in Google Search Console, then examine its crawl and indexing reports. Mueller said it was impossible to say without more information.
What to Do Now
- Compare the indexed URL set. Check which URLs are indexed now and identify pages that were indexed before the decline.
- Review crawl and indexing reports. Look for evidence involving internal links, crawled pages, indexed pages and blocked resources.
- Assess the site’s quality. Review the affected pages for unique, useful content.
- Confirm that remediation is complete. Ask the security team or developer who handled the cleanup to confirm that compromised code, unauthorized content and related technical damage were removed. Mueller identified incomplete cleanup as a possibility, not a confirmed fact.
- Run a technical audit. Review indexability, crawl errors, blocked resources, redirects, canonical tags, duplicate or thin pages and internal-link problems. Monitor the site after corrections and compare its indexed URLs with the earlier baseline.
Before You Diagnose
A homepage-only index is a symptom. Quality, incomplete security remediation and technical issues are candidate explanations that need separate evidence.
What Observable Evidence Should You Record?
- Scope and timing: Record when the change began, which URL types disappeared and whether a site release, incident or search update occurred near the same time.
- Internal-link discovery: Check whether important pages are still linked from crawlable pages and whether the reported internal links remain discoverable.
- Page usefulness: Ask the content owner whether the affected pages contain distinct, useful information.
- Site and incident changes: Record what changed in templates, content, hosting, permissions or incident remediation. Ask the developer or security lead to confirm when the compromise began, how long it lasted and what cleanup changed.
Audit Interpretation: Flag vs. Diagnosis
| Audit area | What an audit can flag | What it cannot prove |
|---|---|---|
| Index coverage | Non-indexable URLs and pages absent from the index | The cause of the exclusion |
| Crawling | Crawl errors and blocked resources | The cause of the index decline |
| URL handling | Redirect and canonical issues | The cause of the index decline |
| Content | Duplicate or thin pages | The cause of the index decline |
| Internal links | Internal-link problems and pages that become less discoverable | The cause of the index decline |

What Is Confirmed, and What Is Not?
- Observed in the reported site: Only the homepage was indexed, Google Search Console was not crawling internal links, and the other pages were not being indexed.
- Identified by Mueller as candidate explanations: A general site quality issue, a hack that was not fully cleaned up, or a technical issue. He said the quality explanation might be unrelated to the hack unless the compromise lasted many months.
- Not confirmed: No site-wide diagnosis establishes which explanation applies.
FAQ
Can a Google Search Quality Issue Leave Only the Homepage Indexed?
John Mueller said that, without more information, a site that was previously fully indexed but now has only its homepage indexed can be a sign of a general quality issue. He did not confirm that quality was the cause in the reported case.
Is a Homepage-Only Index Always Caused by a Hack?
No. Mueller said the issue might be unrelated to a hack unless the hack remained in place for many months. He also identified incomplete cleanup and a technical issue as possibilities.
How Can Site Owners Check Which Pages Are Indexed?
