How to handle out-of-stock and discontinued products for SEO

How should you handle out-of-stock products for SEO?

The decision depends on whether the product is coming back. A temporarily out-of-stock product keeps its page live, updates the stock status in structured data and shows alternatives. A permanently discontinued product is redirected with a 301 when a genuinely similar product exists. Pages with no close match and no value return a 404 or 410.

Stock changes constantly in ecommerce, and deleting or redirecting pages every time wastes the search visibility they have built up. Keeping hundreds of "sold out" pages forever is not the answer either, because it frustrates shoppers. The right approach is a clear decision rule for every product.

How does Google understand stock status?

Google's product structured data documentation lists the schema.org values for the availability property inside an Offer. The ones used most in ecommerce are:

Value	Meaning	When to use it
InStock	In stock	Products available to buy
OutOfStock	Currently out of stock	Temporary stockout
BackOrder	The item is on back order	Coming from the supplier, orders accepted
PreOrder	Available for pre-order	Not yet released
SoldOut	Sold out	Limited run, sale finished
Discontinued	Discontinued	Permanently withdrawn product

Visible page content and structured data must say the same thing. If the page says "sold out" but the markup still says InStock, Google may show incorrect information in results. We cover the overall setup in our Product schema guide. If you list products on Google Shopping, update stock in your Merchant Center feed at the same time.

What should a temporarily out-of-stock page do?

If the product will return within days or weeks, the page should stay live and return a 200 status code. Removing it causes Google to drop it from the index, and visibility has to be rebuilt from scratch when the product returns.

Ways to keep the page useful:

• Clear stock message: show "currently out of stock" next to the price.
• Notify me: an email or push alert keeps demand from leaking away.
• Expected date: if you know when it will be back, say so.
• Alternatives: show similar products from the same category high on the page.
• Variant level: if only one size or colour is out, mark that variant as unavailable, not the whole product.

On category pages, moving out-of-stock products to the end of the list lets shoppers see what they can buy first.

How should pre-order and back-order products be shown?

If a product is not yet in stock but you can still take orders, the situation is different. BackOrder covers items coming from a supplier that you can already sell, and PreOrder covers products not yet released. Show a clear message such as "order now, estimated dispatch date" and keep the add-to-cart button active. Being explicit about dispatch timing manages expectations and helps keep returns down. Check that the structured data value matches the on-page message, and that both switch to InStock together when the product arrives. Running pre-order campaigns on the same product page rather than a separate URL means the visibility you build is not lost at launch.

When should a discontinued product be redirected?

If a product will never be sold again, you have three options. The decision table looks like this:

Situation	Recommended action	Why
A direct successor model exists	301 redirect to the new model	The shopper finds the current version
Similar products exist, no exact match	301 redirect to the most relevant sub-category	The shopper sees options
The page still earns traffic and links, and has informational value	Keep it as an information page marked Discontinued	Manuals or spare parts info stay useful
No close match, no traffic, no links	Return a 404 or 410	Don't send shoppers to an irrelevant page

According to Google's redirect documentation, permanent redirects (301 and 308) are used as a signal that the target should be canonical, and the target URL is shown in search results. Use permanent redirects only when you are sure they will not be reverted.

Why is redirecting products to the home page a problem?

Bulk-redirecting every discontinued product to the home page looks easy, but shoppers land on an unrelated page instead of the product they wanted. A bulk redirect tries to pile the value of every removed product onto one page, yet it answers nobody's question. A redirect target should genuinely serve the purpose of the original page; if no such target exists, honestly returning a 404 or 410 is the better choice.

Is there a difference between 404 and 410?

According to Google's documentation on HTTP status codes, all 4xx codes except 429 are treated the same: Google's crawlers signal that the content does not exist, and a previously indexed URL is removed from the index. So do not expect a meaningful SEO difference between 404 and 410. What matters is that a removed page really returns a 4xx code rather than a "product not found" page that returns 200, which ends up in soft 404 reports.

What about seasonal products that come back?

For products that return every year in the same season (for example, a winter coat range or school bags), the best approach is to keep the URL. Out of season, the page stays live with OutOfStock or PreOrder status and comes back into stock at the start of the season. Links and visibility earned in previous years are reused every season.

If the product returns each year under a new model code, redirecting the old model's page to the new one with a 301 provides the same benefit.

How do you make decisions at scale?

Reviewing hundreds of out-of-stock products one by one is hard. This process helps:

1. Export all out-of-stock products from your platform.
2. Tag each product: coming back, permanently discontinued or seasonal.
3. For discontinued products, add clicks from the last 16 months in Search Console and any external link data.
4. Use the decision table above to assign 200, 301 or 404 to each product.
5. Implement the redirects, remove discontinued products from internal links and update your sitemap.
6. A few weeks later, check the soft 404 and 404 reports in Search Console.

The process mirrors the steps used for large URL changes; see our site migration guide for more detail.

Key takeaways

• For temporary stockouts, keep the page live, set availability to OutOfStock and offer alternatives.
• Page content, structured data and your Merchant Center feed should all say the same thing.
• Redirect discontinued products with a 301 only to a genuinely related product or sub-category.
• Avoid mass redirects to the home page; return a 404 or 410 when no relevant target exists.
• Reuse the same URL every year for seasonal products.
