Best AI Content Detector Tools To Avoid Google Penalty

Best AI content detector tools

If you run a blog and hire writers, I know your insecurity. Your major insecurity must be “What if my writers are using AI writing tools?”

Well, why not? In February 2023, Google released its major algorithm update tanking millions of sites using AI content.

With the increasing popularity of AI writing tools, it has become crucial to possess a powerful AI content detection tool to ensure the authenticity of your content.

The world is currently witnessing a significant digital transformation, where AI writing tools are being used to create and manage content.

Prominent examples include Jasper AI, Rytr, Content Bot, and many others, all of which possess remarkable AI capabilities for content creation.

However, there is an important caveat: Google has the ability to identify AI-generated content and does not view it favorably.

Consequently, if your content is solely produced by AI, Google will fade it in various scenarios, severely impacting your website’s SEO and ranking.

It is better to detect the AI content yourself before Google detects it. That’s why I have shared the list of the Best AI Content Detector Tools to save you from further penalties.

How Accurate Are AI Content Detectors?

I have always been skeptical about how accurate AI content detectors are, but my answer has gone unanswered.

I am going to let you know what I have observed from my experience about the accuracy of these AI text detectors. 

You would be disappointed to know the fact that these AI Content Detectors are not 100% accurate, rather they provide service to a good extent of accuracy.

I can say that it lies between 70% to 89%

The reason behind this lack of accuracy in the AI text detector is that AI writing tools like ChatGPT (for example) are extremely good at creating unique content.

These bots can write or generate content just like human beings. 

The advancement of AI writing tools is at its peak, but you do not have to worry.

As we are moving forward with technology, more and more AI content detectors are coming with updates. These can give a one-to-one fight against AI writing tools

Sooner or later, such tools will come which will give 100% accurate results.

How Do AI Detection Tools Work?

Do you know how Google search works? Like how Google finds thousands of results in milliseconds for you?

This is very subtle. Google runs through all the content on websites and searches for the keyword and phrases that you have used or something similar to that. 

In the same way, an AI content detector looks for phrases, words, and sentences for the process of detection.

These tools can give scores as well on how human-written the content appears to be. 

If the detectors are not able to detect the AI-written content, then there is a possibility that Google also is not being able to detect it.

These tools will rate your content on how Google will analyze it. 

These detectors are usually based on the same model as AI writing tools, which is the NLP model.

The AI detector gets training for the patterns used by the writing tools, and based on the patterns, they detect if it is AI-generated. 

Can Google Detect AI-Generated Content?

I have already shed some light on Google’s point of view on AI-generated content, but let me talk some more about it. Google does not like websites and blogs using AI-generated content

They take strict actions against the websites that do so.

The reason why Google does not entertain AI-generated content is that it is not readable, and lacks credibility, creativity, engagement, and relatability

This makes the content very poor and low in quality, which Google does not like at all, and hence flags the website or blog. 

On the other hand, human-written content has an emotional touch, relatability, engagement, and a sense of attachment to the content which automatically increases the credibility and quality of the human-written content. 

If you search for a topic, there are high chances of spun content or AI-generated content getting a lot of traffic.

So, I cannot say that Google is very good at detecting AI-generated content but I would say that Google is working on it every day. 

I have seen many websites getting banned for the same reason. 

For some quick help, here’s a quick tip on how to avoid getting caught by Google when using AI tools:

If you are looking for something free then you can go with Hugging Face, but for better performance, I would suggest Originality.AI.

It is crucial to run the contents given by writers through these detectors so that you can save yourself from punishments by Google.
