With the rise of ChatGPT and similar AI writing tools, many writers are tempted to rely on them to create large volumes of content. However, does AI-generated content truly add value to the vast digital landscape? According to Google’s August 2022 helpful content update, AI-generated content tends to prioritize search engines over readers, and as a result, Google now assigns lower rankings to such content. Google wants content that puts people first, providing valuable information and depth.

Unfortunately, today’s AI writing tools fall short of creating the high-value content favored by Google. These tools rely on existing data and fail to provide meaningful insights or original ideas. So, how can you ensure that your web content is human-written and likely to be indexed by Google? This is where Copyleaks comes to the rescue.
