glb file format

I wanted to look at the quality of Google's first page of search results, using search operators to exclude AI-written articles and remove Google's AI Summary. I used the search operators before: and -ai.

ChatGPT launched in 2022, so by using before: we can filter out results published before then. This will exclude newer articles that might be AI-written. To remove the AI Overview that now appears at the top of search results, we use -ai.

The idea came from this video:

Going through and using the search operators, we can see that the link for https://www.khronos.org/Gltf, which is the organization behind glTF, isn't on the first page of Google results. It only appears after using the -ai search operator to remove the AI Summary.

If we highlight any links from khronos.org, we get links to https://www.khronos.org/files/gltf20-reference-guide.pdf for our before:2018 -ai search, and links to https://registry.khronos.org/glTF/specs/2.0/glTF-2.0.html for our before:2022 -ai and before:2023 -ai searches.

The featured snippet also doesn't use the direct source https://www.khronos.org/glTF, unless we search before:2018 -ai or earlier years.

ChatGPT-written articles have pushed out the actually useful results, and now Google is using those poorly written AI articles as sources for its AI Overview.
