Can Google really exclude your pages from results because of soft 404s?

What is a soft 404 and why does Google care about it?

A soft 404 refers to a page that returns an HTTP 200 (success) code when it should technically return a 404 (not found) or a 410 (definitely gone). Technically, the server says, "all is well," but the content is empty, generic, or worthless.

Google seeks to identify these situations where the response code does not reflect the reality of the page. An out-of-stock product showing "Out of stock" with an almost empty page, a category emptied of all its items, or an internal search that returns no results—these are typical cases.

How does Google detect that a page is a soft 404?

The engine relies on several behavioral and technical signals. Extremely short content compared to other pages on the site, recurring textual markers ("no results," "unavailable," "page not found"), or an HTML structure similar to real 404 pages trigger alerts.

Google also compares the page to its history: if it previously contained substantial content and has suddenly gone hollow, the risk increases. The bounce rate and lack of clicks in Search Console may strengthen the signal, though Google doesn’t explicitly admit this.

Why does this statement change the game for e-commerce?

Many online stores keep unavailable product listings live to retain SEO traffic or sales history. They display a message like "Temporarily out of stock" with a notification form.

If Google deems the content insufficient, the page disappears from results. It doesn't necessarily lose its complete indexing, but it becomes invisible. As long as you don’t update it with valid content, it remains out of play.

• HTTP 200 doesn’t guarantee indexing: content takes precedence over HTTP status
• Pages flagged as soft 404 are temporarily removed from results, not permanently deindexed
• Google does not specify the exact content threshold required to avoid this treatment
• Textual markers ("unavailable," "no results") are red flags for the algorithm
• The time for restoration remains unclear: how long before Google recrawls and reevaluates the page?

Does this statement align with what’s observed in the field?

Yes, and it confirms behaviors seen for years. E-commerce sites with hundreds of empty product listings regularly see their indexing rate drop in Search Console. Google no longer counts them as "discovered but not indexed"; it categorizes them as soft 404s.

What’s new is Mueller’s clarity: he confirms it’s not a bug, it’s a architectural choice of the engine. If the content doesn’t hold up, the page is out of the scope. The issue is that “valid content” remains a subjective notion. How many words? What type of media? Google doesn’t say.

What nuances should be added to this rule?

Google does not treat all unavailable products the same way. A product sheet enhanced with customer reviews, FAQs, videos, and recommendations is at less risk than a skeletal page with just "Out of stock." Context matters.

Then there’s the issue of existing traffic. A page that still receives organic visits or quality backlinks seems to enjoy greater tolerance. Google hesitates to treat it as a soft 404 if it continues generating engagement signals. [To be verified]: this tolerance is undocumented anywhere; it’s an empirical observation.

In what cases does this rule not apply?

Internal search result pages with no results are a borderline case. If your site generates thousands of such URLs, they can be treated as soft 404s even if they technically display a coherent user interface. Here, the right reflex is to block these URLs via robots.txt or noindex.

Pages of temporarily empty categories pose the same challenge. If you sell swimsuits in winter and empty the category, Google may deem it irrelevant. The solution? Add editorial content, guides, or related products to maintain content density.

What steps should you take to avoid treatment as a soft 404?

The first step: audit all unavailable product pages or empty categories. Use Screaming Frog or your favorite crawler to identify pages with little textual content (fewer than 200 words) and markers of "out of stock," "unavailable," or "no results."

For each page, decide on a strategy: either enrich the content (reviews, FAQs, alternatives), redirect with a 301 to a parent or similar page, or go for a 404 or 410 if the product will not return. The HTTP status must reflect reality.

What mistakes should you absolutely avoid in managing unavailable products?

Never allow a page to return a 200 code with almost empty content. This is the perfect scenario for a soft 404. Google prefers a true 404 to a false 200 because it simplifies its crawling and indexing work.

Avoid chain redirections: product A unavailable → category B → sub-category C → homepage. Google loses patience after 3-4 hops and may give up. A direct redirection to the best alternative is always preferable.

How can you check that your pages are not being treated as soft 404s?

Check the “Pages” section in Search Console, tab “Why pages are not indexed.” If you see “Page with redirection” or “Soft 404” on URLs expected to be indexed, it’s a warning sign.

Also compare the number of indexed URLs in Search Console with the actual number of URLs in your sitemap. A significant gap (30% or more) often indicates that Google is filtering out many pages deemed irrelevant.

• Audit pages with fewer than 200 words and markers “unavailable” or “out of stock”
• Enhance exhausted product sheets with FAQs, reviews, guides, or alternatives
• Use a true 404 or 410 for permanently discontinued products
• Redirect temporary empty pages with a 301 to the parent category or a similar product
• Monitor Search Console for soft 404 alerts
• Block automatically generated URLs without value (internal search, empty filters) via robots.txt or noindex
