Oversized product cards
Collection tiles appear around 260-420px wide, but originals are likely loaded at much larger dimensions.

What a Skymage image audit looks like
This anonymized teardown shows the kind of practical output a free audit returns: the likely image problems, the first fixes, and the Skymage URL patterns to test on one page.
sample page
Ecommerce product page
Page type
Product detail page with gallery and related products
Primary risk
Large product gallery image likely becomes the LCP image on mobile
Business impact
Slow PDP load can reduce paid traffic conversion and organic visibility
Recommended test
Replace product card and gallery URLs on one template first
findings
Example audit findings
The real audit uses the URL you send. This example shows the structure and level of specificity to expect.
Gallery format waste
JPEG product images can usually ship as WebP or AVIF for modern browsers at the same visible quality.
Mobile LCP risk
The first gallery image is above the fold and should get explicit dimensions, modern format, and a right-sized URL.
first fixes
Concrete Skymage URL changes
A useful audit should produce implementation-ready examples, not just generic advice.
