A duplicate page or one with very few changes to its content can affect your site's visibility and ranking in search engines .
Therefore, this type of content directly interferes with attracting visitors via organic traffic, which can be detrimental to your marketing strategies.
Both Google and Bing, among other search engines, have clear instructions on how to avoid duplicate content.
But what exactly do these manuals say? How do you usa email database identify duplicate content and, more importantly, what should you do if you find it on your company’s website?
This is what we are going to understand today, in detail. Let's go?
One of the crucial parts of search engine marketing is SEO.
And when we talk about Search Engine Optimization (SEO), or more specifically the technical part of this optimization, there are several points to worry about.
Loading speed, lazy loading for image processing, friendly URLs … All of these issues are important for the performance and user experience on your company’s “virtual showcase”, your website.
Duplicate content is another one of these issues — and perhaps one of the most important among them. So, let’s look at the main definitions?
What exactly is duplicate content?
Duplicate content occurs when significant blocks of the same or very similar text appear in more than one URL on the internet . This can occur within the same website or between different websites.
Google defines duplicate content as any content that “appears in more than one place on the web ,” with a “place” being a distinct URL.
This phenomenon affects page rankings, as search engines have difficulty deciding which version to display to users.
Therefore, duplicate content more than once can lead to:
Traffic dilution : When the same content appears on multiple URLs, traffic is spread across those pages, reducing the relevance of each. This weakens the authority of any given page — and your site overall.
Confusion for search engines : Algorithms can have difficulty identifying which page should be ranked, which often results in both versions ranking lower.
Manual penalties in extreme cases : Although Google does not automatically penalize duplicate content, if a deliberate attempt to manipulate results is detected, the site may be penalized. It is worth noting, however, that this is extremely rare.
Therefore, this type of content directly interferes with attracting visitors via organic traffic to your website, which can be detrimental to your Inbound Marketing strategies , whether for a B2B business or e-commerce, for example.
Let's understand more deeply:
Why does duplicate content happen?
To begin with, it is worth noting that duplicate content on a website does not always have malicious intentions. This practice can happen due to carelessness or even other human errors.
Check out some of the most common scenarios:
Duplicate Reviews
Imagine you are the owner of an e-commerce store that sells electronics.
Your website receives a number of customer reviews about a specific headphone model.
To increase the visibility of this positive feedback, you decide to display these same reviews on multiple pages of similar products, such as other headphone models.
While this may seem like a great way to showcase customer reviews, by replicating the same reviews across multiple pages, you are creating duplicate content, which can compromise your indexing and ranking.
Product pages with the same description
Here we have another very common case in e-commerce. Product pages with the same description can happen by accident or because they are pages from the same category that display the products through widgets or custom codes, for example.
To avoid this problem, each category page needs to be different, with unique descriptions for each of the products — the more personalized and specific, the better.
Copy from another website
Suppose you are the owner of a technology blog and you come across an interesting article on another website that explains in detail the latest trends in smartphones.
If you copy this content in its entirety to your blog, without modifying it or giving credit to the original author, you will be creating duplicate content.
Even if the intention is good, search engines like Google will identify that this content already exists elsewhere, and are likely to give preference to the original site, while your blog may be penalized for having duplicate content.
What does Google say about duplicate content?
But let's look at what our original source says about the matter? According to Google:
“[A copy is] multiple URLs that display the same page content. For example, if one URL on a site displays a list of dresses grouped by size, another displays the same items grouped by color, and a third URL displays the same list optimized for mobile viewing.
Google analyzes a group of duplicate URLs and chooses a canonical one. The canonical URL is the version that best represents the page and has its display adjusted for the "default device type" most commonly used by those visiting the site. In most cases, this is mobile.” Read the full text here.
Additionally, according to other official Google documentation , the company does not directly penalize sites with duplicate content unless it sees a clear attempt to manipulate rankings, as we pointed out earlier.
The main problem, then, is the confusion this creates for the algorithm . When Google finds several versions of the same content, it chooses the one it considers to be the most relevant, which can lead to a drop in visibility of other versions, among some of the other problems we have already mentioned.
