Is Google Able To Detect AI Written Content

Google hasn’t made any official announcement about whether they can detect AI-written content or not. But why AI articles are not ranking anyway, do you why??? Pal, Google knows the quality.

No matter how advanced the AI is; It cannot beat the quality of desirable content that is needed to rank your article.

Usually, the content generated by an AI is very poor if it isn’t reviewed or re-edited by any especially a human writer. That ultimately makes the quality of content poor in the eyes of Google.

We recommend not using AI to rank on Google, instead, use AI tools for offline tasks like paper writing.

New Development: Turnitin Is Gearing Up For AI Content Detection

According to Turnitin officials, they have cracked the usage of Chat GPT content in the documents. As the AI Vice President, Eric Wang said that “they write extremely average.”

The official website also provided an official statement on January 3, 2023, that they are going to develop technology to resolve these issues.


How can I save myself from AI Content Detection?

First of all, you shouldn’t use any AI writer to write for you completely. You can take ideas and knowledge from them and simply edit them in your own language.

Does Google have any special penalty for AI Content?

Well, it’s not clear if Google can detect AI content but it won’t rank your AI article with poor quality. But if you are caught by any specific organization or individual, then they can file a complaint against you as web spam.

Conclusion: AI Content Detection Tools

The use of AI writers is increasing day by day that made many high authorities in worries. It doesn’t mean that they will stay quiet, many startups have been initiated to remove this kind of content from Google.

It is possible that Google and other search engine develop algorithms to detect AI content and provide a strict penalty for that website.

AI writers are just made for our convenience but not to do our job. You can take suggestions, information, and ideas, but you would be a fool if you think like you wouldn’t be caught by these tools.
