In internal site optimization, duplicates are web pages whose content is identical to the content of other web pages. Most often, they appear due to defects in the CMS or as a result of erroneous actions of the webmaster. For example, when the site is simultaneously available at and

Next, we will talk about the harm that the appearance of duplicates brings to blogs, news portals and online stores, and how to find duplicate website pages using free and paid methods.

Why you should avoid duplicate pages

Duplicate web pages on the site are dangerous because the uniqueness of the content placed on them is zero. And unique content, as you know, is one of the main components of successful search engine optimization. In addition, the danger of duplicates lies in the following:

  • Let's imagine the situation: you published a cool article on the website, which you ordered from a top author. A week later, when analyzing backlinks, you find that other blogs have started referring to this article. Everything, it would seem, is coming together perfectly - the link profile is growing, and together with them, the position of the site should grow. But this is not happening. And all because other sites rely on a duplicate of the page on which the article is published. There can be no question of the effectiveness of promotion in such cases.
  • Artificial intelligence, on which the operation of large search engines is based, is trained to identify duplicate pages. But sometimes he does it incorrectly and they get issued. As a result, the canonical (original) page, the link profile of which was created for months or even years, remains out of sight of search engine users. Again, this negatively affects the effectiveness of promotion.
  • Web spiders that have determined that there are duplicates on the site begin to visit it less often. As a result, the period during which new content is released increases. In addition, the risks of falling positions increase if the crawler finds duplicates on the site.

Speaking of duplicates, it is also worth noting that not only the content of the web page visible in the browser window, but also the meta tags of the site can be duplicated. In such cases, search engines will return pages with identical titles and descriptions. This confuses users and underestimates the CTR, the value of which seriously affects the ranking of the site.
