How do duplicates affect your Google promotion?

The influence of duplicates on Google promotion

In this article, we will look at how duplicate content can affect your website's ranking in Google. One follower asks: “How does duplicate content affect SEO on Google? What methods of removing duplicates exist? Let's figure it out.

How Google treats duplicates

Google doesn't take kindly to duplicate content, especially when it comes to creating different regional versions of sites hosted on subdomains or subfolders. If the content of the pages differs only in minor changes, such as replacing toponyms, the search engine perceives this as duplicate content. In this case, pages may be indexed, but their ranking will be limited or not at all.

However, if the content was borrowed from other sites but added new value, it may rank quite well in Google. An example of this is aggregators, which, despite using information from other resources, begin to gain traffic after some time. In such cases, Google may consider a page to be unique if it offers value to users. But if we are talking about internal duplicate content on one site, Google is unlikely to promote all such pages, preferring one main version.

There is also a situation where the simultaneous creation of duplicate pages and the loss of indicators on the main version of the page go hand in hand. Although such cases are not so common, they still occur. It is important to consider that this may not just be a coincidence, but a related phenomenon, and you should be careful when creating duplicates.

Thus, Google is not particularly supportive of duplicates, both within the site and on other resources, unless those pages offer additional value. However, in some cases, even complete duplicates may have a chance of ranking well if they still provide something useful.

How to properly delete duplicates

If you decide that one version of your duplicate pages needs to be removed, there are several options to resolve this issue:

• If duplicate content can be highlighted by URL, you can use the directive Disalov in the file robots.txtto block access to these pages for search engines.
• A more effective way is to use 301 redirects from non-main pages to the main version. This approach helps preserve traffic that may have flowed to duplicate pages, as well as any links that may have been placed on them.
• If for some reason a 301 redirect is not suitable, you can use the tag rel="canonical" in section each page. This tag points search engines to the main version of the page. Google generally respects this tag and uses it to determine which page is considered the primary page. Unlike Google, Yandex does not always take this tag into account, which can lead to duplicates being indexed in its search engine, but this does not always cause problems.
• Another method for closing duplicate pages is to use a meta tag robots noindex or title S-Robots-Tag in the HTTP header. This completely excludes duplicate pages from being indexed by search engines.

In summary, among these methods, I would recommend using a 301 redirect as it is the most effective method. The second place in reliability is the use of the tag canonized, then the meta tag noindex or title S-Robots-Tag, and in last place - directives in robots.txt.
