Know the Differences and When to Use Them

When it comes to SEO, controlling how search engines interact with our website is crucial.

Two of the most important tools for this are the disallow and noindex directives.

Let’s explore their differences, when to use them, and how to implement them effectively to optimize website accessibility and ensure the privacy and security of our content.

What is Disallow?

Disallow is a directive used in a website’s robots.txt file to instruct search engines not to crawl certain pages or directories.

In other words, disallow prevents search engine crawlers like Googlebot from accessing specific parts of our website.

How does Disallow work?

To use disallow, we need to create or edit the robots.txt file, which must be located in the root directory of our website.

Within this file, we can specify which areas of the website we want to block from trackers.

Example:

In this example, we are telling search engines not to crawl the directories. /admin/ and /privado/.

This can be useful for protecting sensitive areas or areas that are not relevant for indexing.

What is Noindex?

Noindex is a directive used to instruct search engines not to index a page, even if it is crawled.

This means that the page will not appear in search results.

How it Works Noindex?

To use noindexwe can add a meta tag in the HTML head of the page or set an HTTP header.

This approach allows search engines to crawl the page, but prevents it from being included in the search index.

Example (meta tag):

By including this meta tag in our page’s HTML, we are instructing search engines not to index that specific page.

Main differences between Disallow and Noindex

While both guidelines control how search engines interact with our site, disallow and noindex have different purposes.

• Disallow: Prevents crawling of specific pages or directories. Pages may still be indexed if found through other means (such as external links).
• Noindex: Allows crawling but prevents indexing. The page will not appear in search results even if it is crawled.

Practical Examples of Use

Let’s explore some scenarios where disallow and noindex can be used effectively.

Scenario 1: Site Administration Area

We at iWEBAPP have a website with an administration area (/admin/) that we don’t want to be crawled or indexed.

In this case, we can use disallow to prevent tracking.

This prevents trackers from accessing the admin area, protecting our internal settings and sensitive data.

Scenario 2: Private Content Pages

If we have private content pages that should not appear in search results, we use noindex.

HTML code:

By adding this meta tag to private pages, we ensure that they are not indexed by search engines, maintaining the privacy of the content.

Scenario 3: Strategic Combination

To ensure that a page is neither crawled nor indexed, we can combine disallow and noindex.

This two-pronged approach ensures that the page /confidencial/ not be tracked or indexed, providing an extra layer of security.

When to Use Disallow and Noindex?

Know when to use disallow and noindex is essential for an effective SEO strategy.

When to Use Disallow:

• To block trackers: When we want to prevent search engines from accessing certain areas of the website.
• To protect sensitive areas: Such as administration pages or internal directories that should not be publicly accessible.
• To control website accessibility: Preventing crawling of parts of the site that are not relevant to search engines, avoiding overloading your site’s Crawl Budget.

When to Use Noindex:

• To prevent indexing: When we want a page not to appear in search results, but it can still be crawled.
• To manage page visibility: Controlling which pages users should find in search results.
• To delete duplicate content: Preventing similar pages from cannibalizing search results.

Which one to use to prevent your site from appearing on Google?

If you want to ensure that your website does not appear on Google, the ideal is to use the tagnoindex.

This is because:

• If you use only disallowGoogle won’t crawl the page, but it may still appear in search results if other sites link to it.
• If you use so much disallow as noindexGoogle will not crawl the page and therefore will not see the tag noindex. So, the use of noindex will have no effect.

How to Deindex a Site Already Indexed on Google?

If your site already appears in search results and you want to remove it, we recommend using the Google Search Console Removal Tool.

This is more effective than just adding the tag noindexas it removes the page from search results more immediately.

Common Mistakes to Avoid

When using disallow and noindexsome common mistakes can compromise the effectiveness of these guidelines:

• Block entire site with disallow: Include Disallow: / in the file robots.txt prevents the entire site from being crawled, which is generally not desirable.
• Forget to remove noindex: If we put noindex On pages that we want to be indexed in the future, we need to remember to remove the meta tag.
• Do not test the settings: It is important to test our settings. robots.txt and noindex to ensure they are working as expected. Tools like Google Search Console can help with this.

Additional Tools and Resources

To assist in the implementation and monitoring of disallow and noindexwe can use several tools and resources:

• Google Search Console: Lets test our file robots.txt and check if crawlers are following the directives correctly.
