Google’s John Mueller has once again cautioned website owners and SEO professionals against using the Google Indexing API for unsupported content types. 

Mueller, a prominent Webmaster Trends Analyst at Google, emphasized that the Indexing API is intended for specific use cases, primarily for job postings and livestream content. He noted an increase in spammy misuse of the API.

In a statement shared on Bluesky, Mueller advised, “We see a lot of spammers misuse the [Indexing API](https://developers.google.com/search/apis/indexing-api/v3/quickstart) like this, so I’d recommend just sticking to the documented & supported use-cases.”

When questioned about potential penalties for misuse, Mueller responded, “Will your site get penalized? I’d just use it properly, or not use it. If we wanted to suggest that people could use it regardless, we’d document it as such.”

This reiteration serves as a clear signal to the SEO community that attempting to use the Indexing API for general content indexing, such as blog posts or product pages outside of the specified categories, is not recommended and could potentially lead to unforeseen negative consequences, although direct penalties were not explicitly confirmed.

Stan Ventures advises its clients and the wider webmaster community to strictly adhere to Google’s official documentation and guidelines for all its tools and APIs to ensure long-term website health and search performance. 

Focusing on creating high-quality content and practicing white-hat SEO techniques remains the most sustainable path to online success.
