As an SEO professional, you know that optimizing your website for search engines is crucial for driving organic traffic and improving your rankings. However, there are times when you may want to prevent certain pages from being indexed by search engines, or tell search engines not to follow certain links. That‘s where noindex and nofollow tags come in.

In this ultimate guide, we‘ll dive deep into everything you need to know about using noindex and nofollow tags for SEO in 2024. We‘ll cover what these tags are, when and why you should use them, how to implement them using various methods, and best practices for incorporating them into your overall SEO strategy.

Whether you‘re a seasoned SEO expert or just getting started, this guide will provide you with the knowledge and tools you need to effectively use noindex and nofollow tags to control how search engines crawl and index your website. Let‘s get started!

What Are Noindex and Nofollow Tags?

Before we dive into the nitty-gritty details, let‘s first define what noindex and nofollow tags are:

Noindex tag: A noindex tag is an HTML meta tag that tells search engines not to index a particular page. When a search engine crawler encounters a page with a noindex tag, it will not include that page in its search index, meaning the page will not appear in search results.

Nofollow tag: A nofollow tag is an HTML attribute that can be added to links to tell search engines not to follow those links. When a search engine crawler encounters a link with a nofollow attribute, it will not visit the linked page or pass any link equity (also known as "link juice") to that page.

It‘s important to note that noindex and nofollow tags are directives, not guarantees. While most major search engines, including Google and Bing, respect these tags, some search engines may choose to ignore them. However, using noindex and nofollow tags is still considered a best practice for controlling how search engines interact with your website.

When and Why to Use Noindex and Nofollow Tags

Now that we understand what noindex and nofollow tags are, let‘s explore some common scenarios where you might want to use them:

1. Preventing Duplicate Content

If you have multiple pages on your website with similar or identical content, you may want to use a noindex tag to prevent search engines from indexing the duplicate pages. This can help avoid potential penalties for having duplicate content and ensure that search engines index the most relevant version of the page.

2. Excluding Low-Quality or Thin Content Pages

If you have pages on your website with low-quality, thin, or irrelevant content, you may want to use a noindex tag to prevent those pages from being indexed by search engines. This can help improve the overall quality and relevance of your website in the eyes of search engines and users.

3. Protecting Sensitive or Private Information

If you have pages on your website that contain sensitive or private information, such as login pages, member-only content, or personal data, you may want to use a noindex tag to prevent those pages from appearing in search results. This can help protect your users‘ privacy and prevent unauthorized access to sensitive information.

4. Controlling Link Equity Flow

If you have links on your website that you don‘t want to endorse or pass link equity to, you may want to use a nofollow tag. This can be useful for links to untrusted or spammy websites, paid links, or user-generated content links.

5. Managing Crawl Budget

If you have a large website with thousands of pages, you may want to use noindex and nofollow tags to manage your crawl budget. By preventing search engines from indexing and following unnecessary pages, you can conserve your crawl budget and ensure that search engines focus on your most important pages.

How to Implement Noindex and Nofollow Tags

There are several methods for implementing noindex and nofollow tags on your website. Let‘s explore each method in detail:

1. Meta Tags

The most common way to implement noindex and nofollow tags is through HTML meta tags placed in the <head> section of your web page. Here‘s how to do it:

To add a noindex tag, use the following meta tag:
<meta name="robots" content="noindex">

To add a nofollow tag to all links on the page, use:
<meta name="robots" content="nofollow">

To add both noindex and nofollow tags, use:
<meta name="robots" content="noindex,nofollow">

Here‘s an example of how these meta tags would look in the <head> section of an HTML document:


<html>
<head>
<meta name="robots" content="noindex,nofollow">
<title>Example Page</title>
</head>
<body>
...
</body>
</html>

2. HTTP Headers

Another way to implement noindex and nofollow directives is through HTTP headers. This method is useful if you can‘t modify the HTML code of a page, such as with dynamically generated pages or content management systems.

To add a noindex directive via HTTP header, use:
X-Robots-Tag: noindex

To add a nofollow directive via HTTP header, use:
X-Robots-Tag: nofollow

To add both noindex and nofollow directives, use:
X-Robots-Tag: noindex, nofollow

Here‘s an example of how to set an HTTP header in Apache using .htaccess:
Header set X-Robots-Tag "noindex, nofollow"

3. Robots.txt

While robots.txt is primarily used to control which pages search engines can crawl, it can also be used in conjunction with noindex and nofollow tags to fine-tune your indexing and linking preferences.

For example, you can use robots.txt to disallow search engines from crawling specific pages or directories, and then use noindex tags on those pages to ensure they don‘t get indexed even if they are somehow crawled.

Here‘s an example of how to disallow crawling of a specific directory using robots.txt:


User-agent: *
Disallow: /private/

This robots.txt directive tells all search engine crawlers (User-agent: *) not to crawl any pages in the /private/ directory.

Checking if Noindex and Nofollow Tags Are Working

After implementing noindex and nofollow tags, it‘s important to verify that they are working as intended. Here are a few ways to check:

  1. Use Google Search Console‘s "URL Inspection" tool to see how Google views a specific page. If the page has a noindex tag, the tool will display a "Excluded by ‘noindex‘ tag" notice.

  2. Perform a site: search in Google for the specific page. If the page has a noindex tag and has been crawled since the tag was added, it should not appear in the search results.

  3. Use a tool like Screaming Frog or DeepCrawl to crawl your website and identify pages with noindex and nofollow tags. These tools can help you ensure that the tags are implemented correctly and consistently across your site.

Common Mistakes to Avoid with Noindex and Nofollow

While noindex and nofollow tags are powerful tools for SEO, they can also cause problems if used incorrectly. Here are some common mistakes to avoid:

  1. Overusing noindex tags: Noindexing too many pages can limit the amount of content available for search engines to index, potentially hurting your search visibility and traffic.

  2. Noindexing important pages: Be careful not to accidentally noindex important pages like your homepage, key landing pages, or pages with valuable content.

  3. Inconsistent use of noindex/nofollow: Ensure that noindex and nofollow tags are used consistently across your site. Inconsistencies can confuse search engines and lead to indexing issues.

  4. Not updating tags when necessary: If you make changes to a page‘s content or status, remember to update the noindex/nofollow tags accordingly. Failing to do so can result in pages being indexed or links being followed unintentionally.

Alternatives to Noindex and Nofollow

While noindex and nofollow tags are useful for controlling indexing and link following, there are other techniques you can use to achieve similar goals:

  1. Canonical tags: If you have multiple versions of a page and want search engines to index a specific version, you can use a canonical tag to specify the preferred URL. This helps consolidate link equity and avoids duplicate content issues.

  2. Internal linking: By strategically linking to your most important pages and avoiding links to low-quality or irrelevant pages, you can influence how link equity flows through your site and which pages search engines prioritize.

  3. Content pruning: If you have a large number of low-quality or outdated pages, consider removing them entirely rather than relying on noindex tags. This can improve your site‘s overall quality and make it easier for search engines to crawl and index your most important content.

The Impact of Noindex and Nofollow on SEO Metrics

Using noindex and nofollow tags can have a significant impact on various SEO metrics, including:

  1. Crawl budget: By using noindex and nofollow tags to control which pages search engines crawl and index, you can conserve your crawl budget and ensure that search engines focus on your most important pages. This is especially important for large websites with thousands of pages.

  2. Indexation: Noindex tags directly impact which pages are included in a search engine‘s index. Using noindex tags strategically can help ensure that only your highest-quality, most relevant pages are indexed, improving your overall search presence.

  3. Link equity: Nofollow tags prevent links from passing link equity, which can influence how link authority flows through your site. By using nofollow tags on low-quality or irrelevant links, you can conserve link equity and ensure it flows to your most important pages.

  4. Organic traffic: By optimizing which pages are indexed and how link equity flows through your site, noindex and nofollow tags can indirectly impact your organic traffic. However, it‘s important to use these tags judiciously and avoid overusing them, as this can limit your search visibility and traffic potential.

Best Practices for Using Noindex and Nofollow in Your SEO Strategy

To effectively incorporate noindex and nofollow tags into your SEO strategy, follow these best practices:

  1. Use noindex and nofollow tags sparingly and strategically. Only apply them to pages that truly warrant exclusion from indexing or link following.

  2. Regularly audit your site for pages with noindex and nofollow tags to ensure they are being used appropriately and consistently.

  3. Monitor your search presence and organic traffic after implementing noindex and nofollow tags to ensure they are having the desired impact.

  4. Keep an eye on your crawl budget and indexation levels using tools like Google Search Console. If you notice significant changes, investigate whether your use of noindex and nofollow tags may be a contributing factor.

  5. Continuously evaluate and adjust your noindex and nofollow strategy as your website and SEO goals evolve. What works today may not be optimal in the future.

By following these best practices and staying up-to-date on the latest noindex and nofollow techniques, you can effectively use these tags to optimize your website for search engines and drive more organic traffic.
