The default ecommerce platform behaviour for out-of-stock is one of three: hide the product (returns 404), show it with a ‘sold out’ badge, or remove it entirely. All three can be wrong depending on context. Here’s the decision framework.
The four scenarios
Temporary stockout (will restock): Keep the page live. Show ‘currently unavailable’ with notify-me functionality. In schema, mark availability as ‘OutOfStock’ but keep the URL indexable. Don’t lose the page authority — you’ll need it back.
Permanent discontinuation, single replacement: 301 redirect to the replacement product. Preserves backlink equity and ranking signals.
Permanent discontinuation, no direct replacement: 301 redirect to the parent category page. Don’t 404 if the URL has any backlinks or organic traffic.
Mass clearance (50+ products at once): Audit which had real traffic / backlinks. Redirect those to relevant categories. 410 (Gone) the rest — tells Google to remove them cleanly.
What Google actually penalises
Out-of-stock products that stay indefinitely with no path forward signal to Google that your catalog is unreliable. Especially bad if multiple key products are affected. The fix: dates. If something is coming back, communicate an ETA. If not, redirect.
Schema availability values
- InStock — available now.
- OutOfStock — not available but will be back.
- Discontinued — never coming back. Trigger a redirect.
- PreOrder — coming soon, accepting orders.
- BackOrder — orderable but ships later than usual.
Use the right one. Google reads these and adjusts how it ranks the page.
Don’t hide; explain
For temporary stockouts, the page should clearly say: ‘Currently unavailable. Expected back: {date}. Notify me when it’s back.’ That’s a better user experience than a 404 and preserves SEO value.
Common platform-specific gotchas
Shopify: ‘Hide from search’ on a product returns a soft 404 (page exists but no content). Worse than a proper redirect. Use the redirect tool instead.
Magento: ‘Disabled’ products return 404 by default. Use URL Rewrites to set up 301s before disabling.
WooCommerce: ‘Out of stock’ status keeps the page; ‘Draft’ or ‘Trash’ takes it down. Use redirects via Yoast / Rank Math.
Building a stockout audit habit
Most ecommerce stores accumulate hundreds of out-of-stock products over years. Quarterly audit: review which URLs are receiving traffic or have backlinks, redirect or restore as appropriate. Catches losses before they accumulate. Covered as part of our Technical Ecommerce SEO retainer.
