What does it mean to add the noindex argument. Noindex tag in Yandex - hiding code from indexing in Yandex

Nofollow— a status indicating that you do not approve of this link.

Based on the above:

Rel=nofollow- defines the relationship of your link to the landing page as unapproved. In relation to search engines, this attribute indicates to indexing robots that this link should not go to the target page.

Rel=nofollow was introduced and standardized in 2005, in response to a lot of link spam found on blogs. The initiator of the introduction was the Google search engine.

Google When encountering a link with this attribute, it does not follow this link and does not transfer PR weight to the target pages. Also, these links were not taken into account in the calculations of the distribution of link weight among page links. But this was the case until 2010. At the moment, Google also does not transfer link juice and does not follow links with rel = “nofollow”, but the link juice inside the page began to be distributed to these links, but in vain. That is, if your page had PR-10 and 10 links on the page, where 5 of them were closed, then each open link transmitted 2PR to the landing page. Now each open link will transmit 1PR over open links and 1PR into the void over closed links. But this article is not about Google, let's return to Yandex.

Yandex, until April 2010, did not take this status into account. In Yandex recommendations we find a sensational tag , which allowed us to do the same and more. Now there is nofollow.

What is the difference between rel=nofollow and

So what's the problem?
Why did Yandex need to introduce rel=”nofollow” support?

The whole point is that tag this is a personal initiative of Yandex. This tag is not supported or standardized anywhere in the world except by Yandex itself. When checking a resource for errors in the code and supporting web standards, webmasters always received “invalid” code. That is, your resource contains errors. But, I hasten to reassure you, this is not a critical error and practically does not affect anything. For those who care about valid code, here is the structure recommended by Yandex itself for the validity of your code:

Another tag problem The problem is that foreign webmasters, not knowing about this tag, do not use it in the development of their WordPress plugins. These plugins have to be adapted to Yandex reality.
If links in blog comments were closed with the attribute, then these links were open to Yandex. This meant that the robot had to travel to all the links provided in the comments.

Attribute with status rel=”nofollow” standardized and used worldwide to indicate to search engines that a link is not endorsed by the author and should not be followed.
For example, if you close a service page from indexing in robots.txt, but leave the link open, the robot will follow to this page, but will not index it. Why then waste the robot’s resources navigating through unnecessary pages? There is one more nuance: if open links from other external sources lead to your service page, then your seemingly closed page will be included in the search, even if it is closed in robots.txt. I will also talk about this in future articles.

Based on all this, following numerous requests and complaints from webmasters, Yandex introduced support for the standardized W3C attribute with the status rel=”nofollow”. The attribute blocks links from robot clicks and does not transfer weight. Now a lot has become easier. But there is one caveat. Link anchors will be indexed as text.

Why is it needed? ?

Tag very important if you want part of the text, with all link anchors, etc., not to be indexed and not included in the Yandex search database.
For example, you may have official information on your page, or a block of text from a website that is used as a negative example. You do not want the search engine to link your site with this text or index the service information and save it in its database. To do this, this block is framed with the tag .

Unfortunately, such a tool does not exist for Google. It is quite possible that Google or the W3C consortium will pay attention to this tag in the future or come up with their own, and webmasters will receive another useful tool in their toolkit.

How to correctly write rel=nofollow and

In code it looks like this:

This attribute is standardized in HTML, so all search bots understand it correctly and follow the instructions: they do not pass or pass weight. However, the link does not become invisible.

When to use nofollow

There are many situations in which this attribute is indispensable. Nofollow is used when required:

prohibit the transfer of weight to a web resource that search engines consider low-quality;

manage the number of links that should be taken into account by search engines;

prevent weight from being transferred across multiple links in comments.

When using nofollow, you need to be careful, because sites where all links are closed using this attribute do not inspire confidence among search engines.

The noindex and nofollow tags can be used as a value for the content attribute. This is necessary in order to instruct robots in the meta robots tag that there is no need to index anything on this page or follow the links posted on it.

So whether to use nofollow or noindex depends on the goals you want to achieve. For such purposes, there may be a need to hide part of the text, links, or prevent the entire page from being indexed. At the same time, noindex works only for Yandex, and nofollow works for all search engines.

Hello everyone! Today I want to talk about the noindex tags and the nofollow attribute.

noindex tag – what is it?

In short, then No index prevents search robots from indexing any element on the site. This tag is not valid, so many html editors do not accept it. For example, in order for the Wordpress editor to take into account the tag, you need to write:

Don't confuse the tag noindex with attribute noindex, which is written once in the site header.

prevents content inside this tag from being indexed. As for meta name=”robots” content=”noindex, nofollow”, it blocks the entire page from indexing, but I talked about this in this article.

Let's look at the noindex example:

This text will not appear in the Yandex search engine

Also, nesting is not so important, and the tag can be located anywhere in the html code.

Do not forget! If there is an opening tag , then there must be a closing one

Why use noindex?

Let's look at in what cases it is worth using a tag, and in what cases it is not required.

I use when needed:

• Hide the codes of ancient counters if you still use them (LiveInternet, Rambler and others). It is not necessary to include Yandex Metrica and Google Analytics;
• Hide various RSS feeds, subscriptions to newsletters, etc.

No need:

• Block YAN contextual advertising and Adsense from search engines Yandex and Google from indexing. When crawling the page, robots see advertising and do not take it into account;
• If you write external and internal links inside the tag, search engines will not perceive it anyway. Plus it looks stupid when there is another tag that is responsible for nofollow links. But more about it below.

What is the result:

Try to use this tag to a minimum so that there are no differences between the search engines Yandex and Google.

nofollow tag attribute<а>- What it is?

In 2005, Google introduced a new attribute (called the link attribute) Nofollow.

The nofollow attribute is used to block links from indexing by Yandex and Google search robots. This attribute prohibits the transfer of weight from one site to another.

What is the difference from noindex?

Example of a nofollow tag:

Conclusion

To summarize, I want to say that search engines have recently begun to take these tags and attributes into account less than they did, for example, 10 years ago. Therefore, do not focus on just one thing, because now the winner is the one who does everything comprehensively.

Leave comments on the article if you have any questions. And I wish you good luck and promoting your sites using white methods!

To prevent a page from appearing in Google search results, insert a noindex attribute into the page's HTML code or a noindex header in the HTTP request. During crawling, Googlebot will detect it and ignore the page, even if other sites link to it.

Attention! The crawler will not detect the noindex directive if the page blocked in the robots.txt file. Such a page may appear in search results (for example, if it is linked to on another page).

The noindex directive allows you to control access to individual pages of the site, so it is recommended to use it if you do not have access to the root directory on the server.

How to add the noindex attribute

There are two ways to add the noindex directive. Their results are equivalent, and the choice depends on the extent to which you can control the server and how you publish content.

Tag

To block most search robots, add the following meta tag to the section web pages:

If you want to restrict access to the page only to Google robots, use this code:

Other search engines may interpret the noindex attribute on a page differently and show it in search results.

Help us discover meta tags

To detect meta tags, we must crawl your page. If the page continues to appear in search results, it's likely that we haven't yet crawled your site after adding the tag. You can request that Google crawl the page again using the tool. Another reason is that the robots.txt file blocks this URL from Googlebot and the meta tag is not detected. To unblock your page for Google, you need to edit your robots.txt file. This can be done using Robots.txt file checking tool .

HTTP response header

Instead of a meta tag, you can return the X-Robots-Tag header. The response must be noindex or none . An example of an HTTP response where X-Robots-Tag prevents robots from indexing the page.
