Will my site's images be indexed as coming from ShortPixel? The short answer is no. While images are read from https://cdn.shortpixel.ai, we indicate their origin to the Search Engines via HTTP headers. For example, take this URL: https://cdn.shortpixel.ai/spai/w_100,h_100,q_lossy,ret_wait/https://www.wikipedia.org/portal/wikipedia.org/assets/img/Wikipedia-logo-v2.png If we read the headers we'll notice this: The highlighted line is used to signal search engines the original image URL.
