Page set to noindex: how to find the setting and get indexed again

What it looks like in the HTML

Before

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

After

<meta name="robots" content="index, follow">
<!-- or no robots meta tag at all: index, follow is the default -->

Why it matters

Noindex is the reliable way to remove a page from search results, which is exactly why it is dangerous when set by mistake. Once Google recrawls a noindexed page, it drops it from the index, along with any rankings it had. Rankings do not come back instantly after you remove the tag: Google has to recrawl the page first.

Noindex applies only to pages Google can crawl. A page blocked in robots.txt never has its tag read, so do not block pages you are trying to noindex, or pages you are trying to get indexed again.

How WordPress pages end up noindexed

• "Discourage search engines from indexing this site." This checkbox under Settings → Reading adds noindex to every page. It is standard on staging sites, and it is the classic mistake to carry over when a staging site is pushed live.
• Post type or taxonomy defaults. An SEO plugin set to noindex a whole type, pages or products for example, affects every item of it.
• A per-post setting. Someone ticked noindex on one page, perhaps while it was a draft, and never unticked it.
• Maintenance and coming-soon plugins that noindex the site while active.
• Host staging tools that add noindex to staging copies, which can survive a push to production.

How to fix it in WordPress

1. Check the site-wide switch first. Go to Settings → Reading and make sure Discourage search engines from indexing this site is unchecked. Hydrogen SEO's site health score flags this as "Site is hidden from search engines", and while it is on, Hydrogen SEO outputs noindex, nofollow on every page whatever its other settings say.
2. Check the type defaults. In Hydrogen SEO → Robots, look at the Post Types and Taxonomies tables. If the affected page's type has Noindex switched on, turn it off (if the whole type should be indexed).
3. Check the page itself. Open it, press Ctrl+E or Cmd+E for the SEO Settings sheet, open Robots Meta, and switch off No Index. Save the post.
4. Know the built-in rules. Hydrogen SEO always sets noindex, follow on author archives, search results and the 404 page, and Noindex Empty Archives (on by default) noindexes categories and tags with no posts. The homepage has its own Noindex switch on the Homepage screen.
5. Check the HTTP header too. A robots directive can also arrive as an X-Robots-Tag HTTP header from the server or a security plugin. curl -I https://example.com/page/ shows it. This audit reads only the meta tag.
6. Ask Google to recrawl. In Search Console, inspect the URL and click Request indexing. Resubmit your sitemap if many pages were affected.

When you can ignore this warning

Noindex is correct on thank-you and confirmation pages, internal search results, login and account pages, thin archives, and pages that exist for visitors but should not compete in search. If the flagged page is one of those, leave it. Just make sure noindexed pages are not in your XML sitemap; Hydrogen SEO leaves them out automatically.

How to check the fix

View source and search for name="robots"; the content should not contain noindex. Purge your page cache first, since cached pages keep the old tag. In Search Console's URL Inspection tool, run a live test and check that indexing is allowed. Rerun the free SEO audit on the URL.
