SEO scores dropped on the new sites (mostly 61-69 vs 85-100 retro). Usually missing meta descriptions, canonical tags, or lang attrs. Fix before using any of these as published case studies.

Metal Warehouse CLS regression (0.001 → 0.314) is the one red flag. Something on the Astro homepage is shifting layout after first paint. Likely a hero image, font swap, or ad/iframe dimension issue. Worth fixing before pitching this one.
