Google Store's Pixel Watch 5 page has 109 images. 47 of them had no alt text, and the menu images carried labels such as "Phones" and "Browse all offers". We ran the page through Image Optimizer's page scan in DEJAN App. Across the 95 images we report on, the average match between each image and its alt text rose from 30% to 84%. The page's main content images went from 2% to 93%.

The full scan is public: Google Store page scan, with every image, its old and new alt text and both scores.
Of the 48 images with real alt text, 30 scored under 60%.

The scan fetches the whole page and lists every image with its alt text and where it sits. One AI call sorts the images into the ones the page is about and the rest (menus, icons, badges), and writes alt text for images that have none. Each image then gets one of three fixes:
We deep-optimized the 61 main content images and used Quick Fix on the 46 menu images. Two decorative images were marked to keep an empty alt.
The score is the match between an image and its alt text as Google's multimodal embedding model sees it: the model places both in the same vector space, and the closer they sit, the higher the score. Image and text pairs rarely go above a cosine similarity of 0.60, so the tool shows 0.60 as 100%. Product, model and brand names in the original alt text are kept as written.
The store's alt text for this image describes "a macro shot of two Pixel Watch Two-Tone Leather Bands". The image is a collage of people wearing them. That text scores 43%. The first rewrite describes the collage and scores 77%. Each later rewrite sees the image and every earlier version with its score, keeps what raised the score and drops what lowered it. Step 10 won with 87.4%, 0.1 points above step 7.

No image scored lower after the rewrite.
We report on 95 of the 109 images. On the 14 images with placeholder alt text, the rewriter kept the placeholder words, because it is told to keep names from the original alt text, so we left those images out.
