# Why should I avoid duplicate pages?

## What are duplicate pages? {#what}

Duplicate pages are pages with nearly or completely identical text content that belong to the same site but have different URLs.

For example, a home page can have multiple site addresses:

   * `https://example.com/`;
   * `https://www.example.com/`;
   * `https://example.com/index`;
   * `https://example.com/index.html`;
   * `https://example.com/?utm_source=link&utm_medium=source-example&utm_campaign=partner-offer`.

For pages with matching text, the indexing bot creates a group of duplicates. It then selects one page from this group to be displayed in search results. Occasionally, the bot may change its choice to another duplicate.

<hr>

## Why should I avoid duplicate pages? {#bad}

   * The bot indexes multiple pages instead of one. Crawling duplicate pages wastes time as well as the resources of your site and Yandex Search. 
   * It may take longer to index new pages.
   * Duplicate pages may compete with each other in search results.
   * The indexing bot can consider a duplicate and exclude from search results a landing page that is important for your site. 

<hr>

## Why are there duplicate pages? {#how}

Duplicate pages can emerge due to:

   * Specific features of your content management system (CMS). For example, page URLs may have or have not a trailing slash (`/`).
   * Web server settings that make site pages accessible over HTTP or HTTPS and with or without the `www` prefix.
   * Adding GET parameters to links, such as tracking UTM tags used by advertising systems.
   * The same page appearing in different site sections under different URLs.

<hr>

## In Yandex Webmaster, can I check which pages Yandex Search considers duplicates? {#is}

To get a list of duplicates, use the **Indexing** → **Searchable pages** tool: open the **Excluded pages** tab, find the **Status** column, and apply the **Duplicate** filter. For more details, click the three dots.




To see if a specific page is a duplicate, insert its address in the URL filter. 

To find duplicates emerged due to adding GET parameters to links, run diagnostics: **Website optimization** → **Site diagnostics**.  Information about duplicates will appear in the critical issues section.

In addition, Yandex Webmaster flags these issues on the **Summary** page.

   * [Errors](https://yandex.com/support/webmaster/en/diagnosis/mistakes.md)

## How to remove duplicate pages from Yandex Search? {#2fix}

   * Set up redirects: from alternate site addresses to the primary one, and from duplicates to the desired page.
   * In the page code, specify which of the duplicate pages you want to include in search results using the `rel="canonical"` attribute.
   * Use the robots.txt file to prevent the duplicates from being indexed. 
   * Prevent the duplicates from being indexed by adding the `noindex` rule to the `robots` meta tag in the page code.

## Ungrouping {#sep}

The owner of a site that has subdomains and often appears at the top of search results may request to reclassify their domain as a web portal through Yandex Webmaster. To do this, you have to provide a description of the services on the subdomains and their owners.

- Different site pages are recognized as duplicates


  Pages with different content can be considered duplicates if they responded to the robot with an error message (for example, in case of a stub page on the site). Check how the pages respond now. If pages return different content, [send them for re-indexing](https://webmaster.yandex.ru/site/indexing/reindex/) — this way they can get back in the search results faster.

  To prevent pages from being excluded from the search if the site is temporarily unavailable, configure the [503 HTTP response code](https://yandex.com/support/webmaster/en/error-dictionary/http-codes.md#503).



  <div style="padding: 15px;
