Out-of-Stock Product Pages: Fixing Discontinued Products

Why stock status becomes a crawl problem

A product page is not only a sales page. Over time it gathers backlinks from bloggers and gift guides, it ranks for its name and model number, and it appears in Google Shopping and in people's bookmarks. When the item stops being available, the shop has to decide what that address does next, and most shops never make the decision deliberately. Instead the platform's default takes over: the page stays up with a greyed-out button, disappears from category lists, gets deleted by whoever tidies the catalogue, or redirects to the home page because a plugin was set up that way years ago.

Each of those defaults has a cost. The Ecommerce Crawl flags out-of-stock products so you can see how many you have and where they sit. What the report cannot know is your intent for each one: whether stock arrives next week, never, or only as a newer model. That knowledge sits with you, which is why this fix is mostly about making decisions and then applying them consistently.

The four outcomes that go wrong

• Temporary gaps treated as permanent. A bestseller is deleted during a two-week shortage and recreated at a new URL, losing its links and ranking history.
• Permanent losses treated as temporary. Hundreds of discontinued items stay live for years, thin and unbuyable, filling the crawl with pages nobody can act on.
• Blanket redirects. Every removed product is sent to its category or the home page. Search engines may treat those redirects as soft 404s, so the old URL drops out anyway and the visitor lands somewhere that does not answer their search.
• Markup that disagrees with the page. Product structured data still says InStock while the page says sold out, which can cause problems in merchant listings.

The decision table

Put every unavailable product into one of these rows. The row decides the URL's fate, the status code, the availability value and whether the page stays in your sitemap.

The fourth row surprises people. Some products keep attracting searches long after they stop being sold: a popular kettle model, a toy people want spare parts for, a paint colour customers need to match. A page that confirms the item is discontinued, lists its specifications and points to what you sell instead can keep serving those searchers, and it keeps the links pointing at your domain useful. Only do this where there is evidence of demand, such as clicks and impressions in Search Console for the product name.

What a good out-of-stock page shows

A page kept live while stock is away must still be worth landing on. Google has said pages that are effectively empty can be reported as soft 404s, and an unbuyable product page with only a greyed-out button comes close to that. The aim is a page that answers "can I get this, and if not, what now?"

• A clear status near the price, in words: "Out of stock, expected mid-November" or "Temporarily unavailable". Avoid vague phrases that might also mean the page is broken.
• A back-in-stock alert that collects an email address. Remember that this is personal data: say what you will send and keep consent separate from marketing. This is not legal advice; check your own obligations under UK GDPR and PECR.
• Close alternatives in the same size, price band or use, placed high enough to be seen, not buried below reviews.
• The full product content, including description, specifications, photos and reviews. Do not strip the page when stock runs out; that is exactly when it needs to carry its own weight.

Keep the offer in the structured data, change only its availability, and make sure the value matches the words on the page. The schema.org values are full URLs:

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Product",
  "name": "Fernhollow Enamel Camping Kettle 1.2L",
  "sku": "FH-KET-12",
  "image": "https://www.example.co.uk/images/fh-ket-12.jpg",
  "offers": {
    "@type": "Offer",
    "url": "https://www.example.co.uk/products/enamel-camping-kettle",
    "price": "34.00",
    "priceCurrency": "GBP",
    "availability": "https://schema.org/BackOrder"
  }
}
</script>

Use OutOfStock when you are not taking orders, BackOrder when you are and will ship later, and PreOrder for items not yet released. If you send a product feed to Merchant Center, its availability should say the same as the page and the markup.

Redirects: when they help and when they do not

A permanent redirect is the right move when a discontinued product has a real successor: the same kettle in a new colourway, the 2026 edition of an annual planner, a replacement model from the same maker. A visitor following an old link gets what they were after, and search engines can carry the old page's signals across.

The test is simple. Would a customer who searched for the old product be happy to land on the new one? If yes, redirect. If they would feel misled, do not. A redirect from a specific blue walking boot to a category of mixed boots is borderline; a redirect from that boot to the home page fails the test.

Why category redirects in bulk go wrong

Search engines compare the old and new page. When a large number of unrelated product URLs all redirect to the same category or the home page, the destination does not match what those URLs were about, and the redirects may be treated as soft 404s. The old URL is then dropped from the index much as if it had returned a 404, but the visitor is still sent somewhere confusing. You gain nothing over an honest 404 and lose clarity. A category redirect is reasonable when the category truly covers the same need and the product was one of only a few of its kind in it.

Redirect hygiene

• Redirect straight to the final URL. If a successor is later replaced, update the old redirects so there is no chain.
• Use 301 (or 308) for permanent changes. A 302 tells search engines the move is temporary and keeps the old URL in play.
• Keep redirects in place long term. Links from other sites do not disappear when you remove a redirect a year later.

Letting a product go: 404, 410 and the page people see

When a product has no successor and nobody is looking for it, removing the page is correct. Google treats 404 (not found) and 410 (gone) in very similar ways; both lead to the URL dropping out of the index, and a 410 can be processed marginally faster. Pick whichever your platform makes easy. What matters more is what a human sees.

Make the error page helpful: a search box, links to your main categories, and ideally a short message that the product is no longer sold. Some shops generate a custom "discontinued" error page that uses the product's old category to suggest alternatives while still returning a 404 status. That gives visitors a way forward without pretending the product still exists.

For site-wide 404 clean-up beyond products, the 404 errors guide covers finding and prioritising broken URLs.

Platform notes

Shopify

Products can be set to continue selling when out of stock per variant, which suits back-orders. Deleting a product returns a 404; to redirect, add the old path on the URL redirects screen in the Shopify admin, which sits alongside the menu settings. Archiving or setting a product to draft also removes it from the storefront, so the URL returns 404 unless you add a redirect. Many themes can sort sold-out items to the end of collections rather than hiding them.

WooCommerce

The setting "Hide out of stock items from the catalogue" under WooCommerce, Settings, Products, Inventory removes those products from category pages but leaves the product URLs live. On a large shop that quietly creates orphans: pages still indexed, still in the sitemap, but no longer linked from anywhere. If you use it, make sure important items are still linked elsewhere, or sort them to the end instead. Trashing a product produces a 404; redirects need a plugin or server rules.

Magento and Adobe Commerce

The "Display Out of Stock Products" option in the stock configuration controls whether sold-out items appear in listings. Disabling a product makes its URL return 404. When you change a URL key with "Create Permanent Redirect" enabled, Magento writes the 301 for you, but discontinued-to-successor redirects must be added as custom URL rewrites under Marketing, SEO and Search.

The fix, step by step

Edge cases

• One variant sold out. If a single size is unavailable, the product is still in stock. Mark that variant's offer as out of stock and leave the page alone. Variant URL handling is covered in Fixing variant URL strategy.
• Products that vanish and reappear often. Small-batch and handmade items can sell out every week. Never delete them between batches; keep the page and use back-order or an alert.
• Seasonal ranges. Items that return every year need a slightly different approach, set out in Fixing seasonal product handling.
• Legal or safety withdrawals. If a product is recalled, remove it quickly and follow the recall notice requirements that apply to you. SEO considerations come second.
• Several old products, one successor. It is fine for many discontinued models to redirect to one new model, provided each is a genuine predecessor.
