How to fix search results indexable on Magento Open Source

Steps for Magento Open Source

1. Follow the same steps as Adobe Commerce (Magento) above — the layout XML approach and robots.txt editor are identical in Magento Open Source.
2. The search results layout handle is catalogsearch_result_index.xml in the Magento_CatalogSearch module.
3. Flush caches after saving: php bin/magento cache:flush from the server CLI.

<meta name="robots" content="noindex,follow">

# robots.txt addition (adjust path to match your platform)
User-agent: *
Disallow: /search
Disallow: /search/

What is search results indexable?

When a visitor types something into your store's search box, the results appear on a URL like /search?q=red+shoes. These pages are generated on the fly — there are potentially millions of them (one for every possible search term). They contain no unique content of their own; they just pull together product listings that already exist elsewhere on your site. "Search results indexable" means Google can currently crawl and index these pages, which it should not be doing.

Letting Google index your internal search results wastes your crawl budget — Googlebot spends time on throwaway pages instead of your real product and category pages, which can slow down how quickly new products get discovered and ranked. These pages are considered "thin content" and can dilute the overall quality signal of your site, potentially dragging down rankings across your entire domain. They also create a near-infinite duplicate URL space (every search query is a new URL) that can trigger duplicate-content issues. Blocking them is a well-established best practice recommended by Google itself and costs you nothing in organic traffic — nobody finds your site via a search results page.
