Crawling vs. Indexing: A noindex tag allows search bots to visit and crawl a page, but it stops them from adding that page to the public search directory.
Implementation Methods: You can add <meta name=”robots” content=”noindex”> into the <head> section of your page HTML, or send it via server HTTP response headers.
Robots.txt Conflict: Never block a noindex page using a robots.txt “disallow” rule. If a bot cannot access the page, it will never see the noindex instruction, and the page might still show up in search results if other sites link to it.
How It Functions NoIndex
- The Visit: Search bots like Googlebot visit and crawl the webpage normally.
- The Read: The bot reads the code inside the page head—such as
<meta name="robots" content="noindex">—or checks the server response headers.
- The Action: The search engine skips adding the page to its search index, or drops it if it was already there.
Key Rules for Success
- Must be Crawlable: The page cannot be blocked by a
robots.txtfile. If a bot cannot visit the page, it will never see the noindex rule.
- Differs from Disallow: A
robots.txtdisallow stops crawling, while noindex allows crawling but stops listing the page on search pages.
If you want, tell me:
- What platform your website is built on (WordPress, Shopify, custom code, etc.)
- Which page or pages you want to hide
I can show you the exact steps to add the noindex rule.
How Implementation Works
- Meta robots tag: Placed inside the
<head>section of a webpage’s HTML code (e.g.,<meta name="robots" content="noindex">).
- HTTP response header: Sent by the web server in the response headers before the HTML content loads, which is useful for non-HTML files like PDFs.
- Crawler behavior: The search bot must be able to crawl the page to see the
noindextag; if blocked by arobots.txtfile, the bot won’t see the rule and the page might still get indexed through external links.
Key Rules and Distinctions
- Crawling vs. Indexing:
noindexstops a page from being stored and shown in search, but the search bot still visits and crawls the URL unless blocked elsewhere.
- Not in Robots.txt: Placing a
noindexrule inside arobots.txtfile is not supported by major search engines like Google.
