Whether you are a business manager or in charge of marketing, Understand the subtleties of this beacon will transform your approach online. So, ready to lift the veil on this mysterious no index?
What is the no index tag (Noindex)?
The no index tag is a small HTML code which gives a clear instruction to the search engines: Do not index a specific page. This means that this page will not be displayed in the results of engines like Google, Bing or others.
In other words, it remains accessible to users with the link, but invisible to the general public sailing via search engines.
This tag is used for strategic reasons:
- protect sensitive pages,
- avoid diluting the SEO potential of a site,
- Or manage obsolete pages.
Thanks to this feature, we keep an increased control over what we want to make public or confidential on the web.
Concrete example
Imagine that you have a test page or an old expired promotion. Rather than letting it pollute your results, you can apply an index. Clever, right?
To go further, know that the No index tag is often combined with other attributes such as “no follow” for even more precision in pages management.
Why use no index in SEO?
Avoid duplicated content
Duplicated content is a scourge for SEO strategies.
Google does not appreciate that the same information is present on several pages, because it complicates its classification work.
Using no index on pages that use the same content or nearby versions (such as pages produced with variants), you protect your site from potential SEO sanctions.
Offer better referencing of strategic pages
Each page indexed by Google consumes a share of your Crawl budget.
By limiting indexing to strategic pages – those that generate traffic or conversions – you focus the efforts of search engines on what really matters.
This boosts the visibility and overall efficiency of your site.
Protect sensitive information
Some pages simply should not appear in the search results.
Think of a connection page, a customer area or a payment form. With no index, these pages remain accessible to your users but invisible for search engines, thus avoiding safety problems or navigation errors.
Manage the pages temporarily unnecessary
When you set up seasonal campaigns or pages of temporary events, you can use no index to remove them from SERP (results pages) once they are no longer relevant, while preserving their content for future use.
When not to use the no index tag?
Ah, big question! Do not abuse this tag as we abuse chocolatines (or chocolate breads, depending on your camp).
On strategic pages
Pages that generate organic traffic, conversions or leads must be indexed. A NO index error here could literally sabotage your SEO strategy.
If the page receives a lot of backlinks
A page with many incoming links loses its SEO potential if it is in no index. These backlinks will not benefit your site and the “SEO juice” will be wasted.
Without controlling your redirects
Before removing the indexing of a page, make sure it is not the main entry point for your users. Also check that it redirects properly if it is required to disappear.
After understanding the essential importance of the no index tag in your SEO strategy, let’s move on to the practical aspect: How to integrate it into one of your web pages ?

Add the following line to your Robots.TXT file to prevent search engines from indexing a page:
User-agent: *
Disallow: /votre-page-a-ne-pas-indexer/
