Funnel score
8-point CRO breakdown
How well the landing page behind the ad is built to convert, scored across 8 factors: offer, copy, speed, trust, mobile, message-match, CTA, and social proof.
This landing page has critical CRO issues. The ad promotes specific KOSAS beauty products with detailed benefits, but users land on a generic sign-in page with zero product visibility. This creates immediate friction and message mismatch. The page forces authentication before users can see products, which is a major conversion killer for cold traffic. Combined with a poor PageSpeed score (35), slow load times will compound abandonment. The sign-in page lacks any product imagery, offer details, or incentive to proceed. Best practice would be to land users directly on the KOSAS product collection or specific product pages, potentially with a 'Shop as Guest' option.
What this page does right. Steal these.
- Mobile experience: Mobile layout is clean and functional with properly sized input fields and buttons. Good vertical spacing and readable text
Where it leaks conversions
- Page speed: PageSpeed score of 35 is poor. Slow load times will increase bounce rate and negatively impact conversion
- Social proof: No visible social proof, reviews, ratings, testimonials, or user-generated content on this sign-in page
- Message match: Severe mismatch: Ad promotes specific KOSAS products with benefits (lengthening, peptides, hyaluronic acid) but landing page is a generic sign-in screen with no product visibility or offer details
- Offer clarity: Ad mentions specific KOSAS products (Soulgazer Mascara, Peptide Lash Serum, Eyeliner) but landing page is a generic search results page with no visible product focus or special offer details
- Headline: Headline 'KOSAS AT SEPHORA' is generic and doesn't communicate value proposition or urgency. Doesn't match the specific product messaging in ad text
- Call to action: 'Sign In' button is prominent but doesn't match ad CTA of 'Shop now'. Creates friction by requiring authentication before browsing products
