Delivering quality content poses a challenge for many brands. It's a continuous process that requires coordination among multiple writers and team members. Moreover, there is fierce competition in search results, making it difficult to rank well and attract targeted traffic.

To overcome this challenge, freelancers may opt to generate articles using Gen AI-powered tools instead of crafting them manually, which may complicate the situation. Thus, the question arises as to whether search engines can detect information assisted by AI. If they can detect AI-written content, will it affect the overall ranking? 

To answer this question, search engine algorithms focus on quality rather than whether the content is written by AI or not. For instance, Google’s search engine algorithm follows EEAT guidelines (Expertise, Experienced, Trustworthy, and Authoritative). If the article meets these criteria, the content is ranked well, and if it doesn’t, like the content is full of fluff, then the content won’t be ranked well. 

Even though, Gen AI tools are improving, the content generated from AI is mostly filled with fluff. That’s why there is a high chance that AI-written content might get rejected. This article will explore AI content detection and outline the resources accessible to businesses for determining whether an article has been AI-generated. Before we get started, let's talk about what AI content detectors are and why AI content detection is so important nowadays.

What is AI Content Detection and How Does it Work?

AI content detection involves determining whether a text is generated by AI or by a human. It is achieved by using a combination of machine learning and natural language processing techniques. 

AI detection tools rely on language models, which are also found in AI writing tools. These models help detect AI-generated content. Specifically, the models search for two key features in a text: burstiness and perplexity.

1. Perplexity

Perplexity is a measurement of a text's degree of unpredictability, indicating how likely it is to make no sense or read strangely to the average reader.

  • AI language models are designed to generate predictable texts with low levels of perplexity. These texts are also more likely to make sense and be read easily.
  • Human writing typically contains higher perplexity due to its creative language choices and a higher rate of typos.

Language models function by predicting and substituting the word that would naturally follow in a sentence. For example, in the statement "I couldn't get to work last…” there are more and less likely continuations.

  • For human-generated content, there will be high perplexity if the sentence is grammatically incorrect or illogical. For example, “I couldn’t get to work last. Pleased to meet you.”
  • For AI-generated content, the perplexity will be low if there is most likely a continuation. For instance, “I couldn't get to work last night.”

If the text is low perplexity, then it is taken as evidence that the given text is AI-generated.


Burstiness measures the variation in length and sentence structure; it's similar to perplexity but focuses on sentences rather than words.

  • Texts with minimal variation in sentence length and structure are considered low burstiness.
  • A text with more variation has a higher burstiness. 

AI text is typically less "bursty" than human text. Language models typically produce sentences with conventional structures and an average length of 10–20 words since they predict the word that is most likely to appear next. This indicates that writing by AI can appear monotonous at times.

A text with low burstiness is probably AI-generated.

The Importance of AI Content Detection

AI content detection is crucial for ensuring the quality and accuracy of content produced by an AI algorithm. Businesses can mitigate legal risks by identifying AI-generated content and refraining from using it without proper authorization. Additionally, it helps ensure that the information aligns with specific criteria for relevance and accuracy. Let’s understand the importance of AI-content detection: 

1. Eliminating Copywriting Allegations

Copyright issues may arise if the source material is generated by an AI algorithm without approval from the original author or owner for advertising purposes. Businesses that identify such content before using it may be shielded from potential copyright infringement lawsuits in the future.

2. Creating Relevant Content

Finding AI-generated content is essential because it ensures that any data used in marketing campaigns is accurate and relevant to the target market. AI content detection verifies the accuracy and relevance of any content used for marketing purposes. 

3. SEO Rankings

AI content detection is important for evaluating and ranking material according to several standards, including quality. The content's precision, uniqueness, and utility can be detected for better SEO rankings

4. Risk of Misinformation and Outdated Content

AI text generators may also spread misinformation or false information that may appear convincing due to their writing style. AI content detection has a significant advantage: It aids in the fight against misinformation in the media and ensures that the content you publish is authentic and free from outdated information.

5. Maintaining the Authenticity of Content 

AI content detection is essential for fact-checking and quality control. With this understanding, we can delve into how Google evaluates AI-generated content. This assessment aids in implementing a human touch and empathy in your written content.

Different Methods to Detect AI-Generated Content

AI-generated content can occasionally be identified without the need for an AI detection tool. As AI-generated content becomes increasingly accessible to all writers, content marketers must remain vigilant. Below are some of the most effective methods for assessing and identifying AI-generated content.

1. Examine the Text for Repetitive or Unusual Patterns

Artificial intelligence isn't perfect. Similar phrases may appear in an AI-generated article, and the AI may need more training to distinguish between the two concepts. 

Consider the following example of a text generated by ChatGPT regarding content marketing:


2. Perform a Quick AI Search and Compare

Utilize readily available tools to perform a quick AI generation test. Select your preferred AI content generator and create a prompt specific to your article. Be as specific as possible regarding the topic, length, and structure. See what happens when you click "generate." If the content piece you have and the text generated by the AI tool look almost identical, there is a high chance that the content piece was copied from the Gen AI tool. 

3. Examine for a Lack of Originality

Detecting plagiarism is straightforward with widely used tools such as Grammarly and, which feature built-in plagiarism checkers. These tools compare the content to other online sources to ensure that it has not been copied or stolen from previously published material.

4. Examine Outdated Errors

Ensure the accuracy of your facts. Artificial intelligence may occasionally include information from outdated or irrelevant sources in the content. Quickly examine the article and conduct independent, basic research to ensure coherence.

5. Execute a Contextual Evaluation

Human beings have a more advanced capacity to identify the intricate details of a concept. If you notice that some important information is missing from the article, it may be because artificial intelligence has trouble making connections that a human could. This observation might suggest that the content was generated by artificial intelligence.
