How to Optimize an Image for Google Discover
- Upload the original image: Always start with the highest resolution source available.

- Adjust the 16:9 crop: Use the editor to frame your subject correctly within the 16:9 landscape aspect ratio.

Does a Passing Image Guarantee Google Discover Traffic?
No. While technical image optimization is a critical step, Discover appearance is determined by Google's automated systems. Visibility also depends on page quality, content relevance, user interests, and overall site authority. This tool checks the technical image recommendations only.
