Unique text is a key factor in successful content marketing and business writing. Regardless of whether you are writing a blog article or a press release, the uniqueness of the text determines success in search engines and the company’s reputation.

Why is uniqueness so important in business writing?

  1. Search Engine Optimization (SEO). Search engines like Google value unique content. If you write original texts, you will have more chances to get to the top in search results. SEO plagiarism or duplicate content, on the other hand, can lead to penalties and a decline in the site’s ranking, which negatively impacts traffic and online visibility.
  2. Audience trust. Unique writing demonstrates professionalism and creativity. Uniqueness reflects independent thinking and the ability to express one’s own ideas. That’s why it is important to use a content originality checker like PlagiarismCheck.org every time you write text. It will help you to post unique content.
  3. Competitive advantage. In the competitive online space, unique content enables you to effectively highlight the distinctiveness of your text. In the commercial environment, it attracts more customers.

What is a plagiarism checker?

Unoriginal texts are ranked lower, which means that a site with such content has a lower chance to reach the top in Google and attract an audience. Additionally, using someone else’s text without permission may violate copyright laws.

Uniqueness can be checked using special services. They compare the text with existing materials on the Internet, databases, scientific publications, and other sources to identify matches.

How the content originality checker works

  1. Text scanning. The service analyzes the text or document that the user has uploaded to a special form.
  2. Comparison with databases. The service compares the text with the following databases:
    • Open sources on the Internet
    • Scientific publications
    • Corporate and closed databases (if such a function is provided).
  1. Check the result. The service displays the percentage of originality of the text, underlines plagiarism, and provides links to the pages where it is found.

Duplicate content: SEO mistake

Duplicate content is not often mentioned as a problem in website reviews or SEO forum discussions. Nevertheless, it can cause huge damage to your site.

Since the plagiarism detection market was recently valued around $468 million in 2023, it’s been a huge focus in the marketing world.

Keyword cannibalization happens when multiple pages on a single website contain the same or similar keywords, thereby preventing the search engine from choosing which page is most suitable to display in search results for that keyword.

This phenomenon not only irritates website owners but also negatively affects the site’s ranking by placing it among erroneous or unwanted search results for a particular query.

How to get rid of duplicate content?

There are several ways to solve the problem.

Configure a 301 redirect

This is the primary method for removing duplicate content. Its essence lies in automatic redirection from one web page to another. Bots react to the redirect settings (recording that there is no longer a page at a specific URL).

This method also allows you to transfer link weight from duplicates to the main page. You can use a 301 redirect to eliminate copies of pages that appear as a result of:

  • Violations in the address hierarchy
  • Using URLs in several regions
  • Determining a resource mirror
  • Problems with multiple slashes.

Setting up the robots.txt file

This method helps search bots identify which pages or files should not be scanned. To do this, you need to apply the “Disallow” option. This directive prohibits bots from visiting unnecessary pages: Disallow: /page.

It is worth noting one nuance. If the page in robots.txt is not specified with this directive, then it will still be shown in the search results. The reason is that it has previously been indexed or there are links to it (external or internal).

Meta tags noindex

There are several of them and they can give different commands.

  • It helps to instruct the robot not to index the document and follow the links. The meta tag, unlike robots.txt, is a direct command. Bots will not ignore it.
  • It works differently. It instructs the robot not to index the document, but to follow the links contained within it.

Attribute rel=”canonical”

Sometimes, you need to identify duplicate content on a site, but you cannot delete the web page and must leave it open for viewing. In such situations, the tag on pages with filters and sorting, utm tags, and get parameters will help. It is used if similar content is expected to be used (but in different language versions or domains).

To use the rel=”canonical” attribute, you need to specify the web page address that needs to be indexed. For example, the site features a “Laptops” section. In this category, filters are set to display various parameters, including brand, screen resolution, color, case material, and more. If such pages are not going to be promoted, then you need to specify the general web page of the section as the canonical one. You can create it by writing the rel=”canonical” attribute in the HTML code. It is placed inside.

Best AI detection tools to check text

Artificial intelligence (AI) is actively used to create texts. However, not all areas are allowed to use AI content. For example, in education, teachers want to ensure that students write the papers themselves. In journalism, it is essential that articles are prepared by professionals, rather than being completely generated by a machine.

To identify text created by a neural network, special AI detectors have been developed. In this section, we will consider how they work and which of them is the best.

How an AI checker works

Detectors analyze texts to determine whether they were created by a person or a neural network. They evaluate writing style, sentence structure, word frequency, and other parameters.

Detectors calculate the probability that the text was written by a neural network using statistical models. For example, GPT-generated texts often exhibit an even distribution of words, whereas people tend to have sharp jumps in the use of rare and common words.

An AI checker will detect excessive formality of GPT and a high level of predictability (indicating the AI ​​origin of the text).

Analysis of AI content, plagiarism

Detectors evaluate the complexity of sentences, word choice, and overall style.

  • Neural networks often use redundant phrases for clarification, such as “This means that…”, “In other words…”. Humans, on the other hand, tend to avoid such repetitions, especially in everyday speech.
  • AI tends to write in a formal tone, even if the topic requires a more conversational approach. Human speech, on the other hand, is often more casual and adapts to the context.
  • AI-generated texts often contain monotonous and identical sentence structures, which gives the text a “synthetic” feel. Humans, on the other hand, tend to vary the length and structure of sentences.

Human: “Yesterday we went to the park and ate ice cream. It was fun…”

Neural network: “Yesterday I visited the park, where I enjoyed delicious ice cream. It brought me joy…”.
