The content of a product sheet, a web page or a website is considered as being in Duplicate Content as soon as it is reproduced almost or totally identically elsewhere on the Web.
Search engines then judge the information as being copied. This poses a real problem because they can then sanction the pages concerned, including the original page…
There are two types of duplicate content
The methods and systems used by search engines to calculate similarity are strictly confidential.
Search engines aim to display the most relevant results in relation to the query made.
If two identical pieces of content answer a query made by a user, the search engine will waste time choosing which content to offer to the user and this will degrade the user experience. The engines therefore want to waste as little time as possible in carrying out these tasks while offering the right content.
This is why they “track” duplicate content with very powerful and increasingly precise detection tools and algorithms (kept secret, of course…), sometimes in spite of the site having the authorship of the content.
Indeed, tests have shown that search engines display the content of the oldest and most popular site. This means that a site with the authorship of a content can be judged as a copy by the algorithm of an engine like Google, because it is less popular.
If a website copies other content on the web en masse, the whole site can be penalised and this can lead to a drop in traffic of up to 95%, or even the removal of these sites from the search engine results in the most extreme cases.
Moreover, if you put yourself in the place of a human and not the Google robot, obviously, the prospect or customer realizing that your content is identical to a previously browsed site, will offer little credibility to what you propose…
Finally, Duplicate Content also falls within the scope of Articles L111-1 and L.123-1 of the Intellectual Property Code (France), as it is subject to copyright. Plagiarising content can therefore be severely punished by law.
This starts even before the publication of new content. It is advisable to use solutions that allow you to check whether the content may be subject to Duplicate Content or not (as a reminder, it is impossible to know the algorithms used by the search engines, but it is possible to come close).
To do this, there are 3 use cases:
In the case where two contents on your site are voluntarily identical, you must integrate “rel=cannonical” tags with the original URL or 301 redirects, which will indicate to the crawlers which is the original content, which will be the only one to be indexed.
You can also use the “Noindex” tag to avoid indexing a page with content copied from another page or another website.
If your website is multilingual, if you want to implement an international SEO strategy, or if you simply have identical content translated into several languages in several countries, you should use the hreflang tag. This tag makes it clear to search engines that the content is not competing with each other, but is aimed at different localities and therefore different audiences.
Finally, in the case where you are simply quoting sources, quotations, sentences quoted by experts, it is perfectly possible for you to display this content by putting your texts between the <blockquote> tags. Displaying this type of content on your website is even recommended to improve the user’s reading experience, prove your expertise to the user and improve your natural referencing.
It is possible that the CMS tools you use allow you to make such SEO settings (plugins…).
If you use an external service provider to write your content, it is necessary to specify that the content provided by the service provider will only be used by you and that this content has not previously been provided to third party websites.
