Every brand, scored.

“The 'ADD TO CART' button is prominent on mobile above the fold, but there is no sticky/persistent CTA bar visible on scroll in the mobile screenshot. As the user scrolls past the buy box, the CTA disappears and is not anchored to the bottom of the screen.”

+9 more findings

“The 'Add to Cart' button is a full-width dark button visible in the mobile screenshot, but it is NOT sticky — it appears only in the purchase module below the fold. During scroll through the hero and image carousel, there is no persistent CTA accessible to the thumb. A sticky bottom bar is absent.”

+10 more findings

“No customer photo reviews or UGC are visible anywhere in either screenshot. No press mentions, 'As Seen In' bar, or named media badges appear on the page — the Trustpilot bar is a platform badge but no named press outlets (Runner's World, TechRadar, etc.) are cited.”

“PSI mobile score is 61/100 — LCP of 9.9s and FCP of 5.4s are critically slow for a cold mobile visitor. A nearly 10-second wait before the largest content element loads will cause significant bounce on first visit, especially on mid-tier mobile connections.”

+12 more findings

“No return policy, money-back guarantee, or warranty language is visible near the CTA on either mobile or desktop. For a $259.99 smart home device, the absence of a visible guarantee near the buy button is a meaningful trust gap that likely increases cart abandonment.”

+10 more findings

“PSI mobile score is 54/100 with an LCP of 35.9 seconds and FCP of 8.7 seconds. These are critically slow load times for a cold mobile visitor — a 35-second LCP means the hero image takes over half a minute to fully render, which will cause significant bounce before the page is even usable.”

“PSI mobile score is 25/100 with LCP 5.9s, FCP 4.4s, TBT 6,020ms, and CLS 0.139. This is a catastrophically slow cold-load experience — a first-time mobile visitor waits nearly 6 seconds to see the main product image and the page is nearly unresponsive for 6 full seconds due to blocking JavaScript.”

+7 more findings

“Star rating (5 stars) and review count (9 Reviews) are visible near the product title on both mobile and desktop — good placement. However, only 9 reviews is extremely thin social proof for a purchase decision, scoring 0 pts on review volume.”

+9 more findings

“The 'Add to Cart' CTA button is visible on mobile but is NOT sticky on scroll — it appears inline in the page flow and disappears as the user scrolls through the large color/variant grid. The variant selector contains 20+ color options across two sections (standard colors + Limited Edition), which creates significant scroll distance before reaching the CTA.”

+9 more findings

“No customer photo reviews or UGC are visible anywhere on the page in either screenshot. No press mentions, 'As Seen In' bar, or named certifications appear — only generic trust icons ('1-year Warranty', '30 Day Return', 'Free Shipping $90+') which do not qualify as named press or real certification badges.”

+9 more findings

“PSI mobile score is 25/100 with LCP of 18.5s and TBT of 3,530ms — a first-time mobile visitor waits nearly 20 seconds for the largest content element to paint. This is a critical conversion killer for a $179.95 impulse-adjacent purchase.”

+7 more findings

“No video content is visible anywhere on the page — no autoplay loop, no embedded YouTube/Vimeo, no video thumbnail. For a smart home electronics product where motion detection, two-way audio, and night vision are key differentiators, the absence of video is a significant missed opportunity.”

+12 more findings

“Only 2 product images are visible in the thumbnail rail (both appear to be white-background product shots of the link hardware). There are no lifestyle images showing the extension kit installed on a watch band on a wrist, which is critical for a small accessory where fit and finish are the purchase drivers.”

+9 more findings

“No sticky Add to Cart button on mobile scroll — the CTA disappears as the user scrolls into the description and review sections, requiring a scroll back up to purchase.”

+12 more findings

“PSI mobile score is 1/100 — catastrophic. LCP of 207.3 seconds, FCP of 6.2 seconds, CLS of 0.814, and TBT of 4,520 ms mean the page is effectively broken for cold mobile visitors. A first-time customer on a typical mobile connection will stare at a blank or partially loaded screen for minutes.”

+7 more findings

“CTA button reads 'SELECT A PHONE MODEL' — this is a gating state, not a purchase CTA. Until a phone model is chosen, there is no 'Add to Cart' button visible. First-time visitors may not understand they must select a model before they can buy, creating immediate confusion.”

+10 more findings

“The 'Add To Cart' button is green, prominent, and visible above the fold on mobile. The page shows 'In stock, ready to ship' stock status. However, there is no sticky Add to Cart bar observed on mobile scroll — once the user scrolls past the CTA into the FAQ accordions and bundle section, the button disappears and requires scrolling back up.”

+8 more findings

“The 'ADD TO CART' button is visible on mobile but does not appear to be sticky on scroll — below the color swatch grid and bandwidth selector, it is a static button. A visitor scrolling through the long color swatch grid (30+ color options visible) loses sight of the CTA with no persistent sticky bar to recapture intent.”

+9 more findings

“Shipping information is collapsed inside an accordion labeled 'Shipping' at the very bottom of the page. No free shipping threshold or delivery estimate is visible near the CTA. This forces buyers to hunt for a key purchase decision factor.”

+9 more findings

“PSI mobile score is 30/100 with LCP of 21.2 seconds and TBT of 1,400 ms. For a cold first-time mobile visitor, the page is effectively unusable for over 20 seconds before the main content renders. This is a critical conversion killer for paid traffic landing on this page.”

+7 more findings

“PSI mobile score is 3/100 — catastrophic. LCP of 37.9s means the hero image takes nearly 38 seconds to fully load on a cold mobile visit. TBT of 6,890ms and CLS of 0.96 indicate severe layout thrashing and a completely blocked main thread. This will cause the majority of cold mobile visitors to bounce before the page is usable.”

+7 more findings

“The 'Add to cart' button is visible on mobile but is NOT sticky — it appears mid-page and disappears on scroll. Once the user scrolls past the bundle/variant section, there is no persistent CTA anchored to the bottom of the screen. This is a critical gap for a $235 product requiring consideration.”

+9 more findings

“The yellow 'Add to Cart' button is prominent and visible above the fold on mobile. However, there is no sticky CTA bar observed on scroll — once the user scrolls past the buy zone into the video and lifestyle sections, the button disappears and requires scrolling back up to purchase.”

“PSI mobile score is 15/100. LCP of 13.9s and FCP of 5.6s mean most first-time mobile visitors will stare at a blank or partially loaded screen for over 5 seconds. CLS of 0.885 is catastrophically high — layout shifts will cause mis-taps on the 'Buy Now' button. TBT of 730ms signals heavy main-thread blocking.”

+7 more findings

“PSI mobile score is 35/100 with an LCP of 22.4s and TBT of 910ms — the page is effectively unusable on a cold mobile load. A 22-second largest contentful paint means most first-time visitors will bounce before the hero image renders.”

+7 more findings

“No star rating, review count, or customer reviews are visible anywhere above the fold or near the CTA on either the mobile or desktop screenshot. There are no press mentions, 'As Seen In' bar, or named certifications visible on the page. The trust badges shown (Free Shipping, 2-Year Warranty, 30-Day Returns, Service & Support) are generic policy icons, not third-party validation. This is the single biggest conversion gap on the page.”

+7 more findings

“Product name 'AIR-1 Air Quality Sensor' and price '$109.99 USD' are both below the fold on mobile — the image gallery dominates the entire above-fold viewport, pushing all text content down. A first-time visitor sees only the hero image and compatibility badges before scrolling.”

+14 more findings

“The primary CTA 'Make a Selection' is not sticky on mobile scroll — once the user scrolls past the button area into the description and accessories section, there is no persistent Add to Cart button anchored to the bottom of the screen. The 'Buy with Shop' button is present but secondary. A cold visitor scrolling through accessories has no one-tap path back to purchase.”

+9 more findings

“No customer photo reviews, UGC imagery, or press/media mentions ('As Seen In' bar) are visible anywhere on the page. For a premium-priced titanium band, the absence of third-party validation beyond 55 text reviews is a significant trust gap.”

+8 more findings

“Only 2 thumbnail images are visible in the gallery (one product shot, one lifestyle/packaging composite). For a $54.99 case competing in a crowded category, 2 images is critically low. Competitors routinely show 6–10 images including on-phone lifestyle shots, drop-test imagery, and close-up texture shots.”

+13 more findings

“No customer photo reviews or UGC are visible anywhere on the page in either screenshot. The reviews accordion is collapsed. No 'As Seen In' press bar, no named media mentions, and no certification badges are present. The desktop banner reads 'OVER 1 MILLION PRODUCTS SHIPPED' — a trust signal, but it is a generic brand claim, not a named press mention.”

+8 more findings

“Star rating (4.8, shown as heart icons) and review count (68 on mobile, 88 on desktop — a discrepancy) appear below the fold on mobile, placed after the product description and Share button. They are not anchored near the product title where they would build trust before the purchase decision.”

+11 more findings

“PSI mobile score is 42/100 — below the 50-point threshold, earning 0 of 10 pts. LCP of 17.8 seconds is catastrophic for a cold mobile visitor; the hero product image is almost certainly the LCP element and is not optimized. FCP of 6.3 s means the page feels blank for over 6 seconds. TBT of 540 ms indicates significant main-thread blocking that will delay interactivity.”

+9 more findings

“Mobile screenshot shows 5-star rating and '1139 reviews' near the product title — strong placement. However, the desktop screenshot shows '0 reviews' with an empty star rating for the same product, suggesting a review widget rendering inconsistency or a variant/page-load issue that could display zero social proof to some desktop visitors.”

+8 more findings

“PSI mobile score is 27/100. LCP of 17.6s and TBT of 3,900ms are catastrophic — a first-time cold visitor on mobile will stare at a blank or partially loaded page for nearly 18 seconds before the hero image fully renders. FCP at 4.8s means even the first paint is painfully slow.”

+7 more findings

“Product name 'Incase ICON Backpack - 23L' and price '$199.99' are both visible above the fold on mobile — solid baseline. However, there is no hero value proposition or headline beyond the product name. Nothing answers 'why this backpack over any other $200 backpack' — no tagline like 'Built for your MacBook' or 'The commuter's carry-all' appears anywhere above the fold.”

+11 more findings

“PSI mobile score is 26/100. LCP of 13.4s and TBT of 2,490ms mean most cold mobile visitors will stare at a blank or partially loaded screen for over 13 seconds before the hero image renders. FCP at 5.2s is also well above acceptable thresholds. This is a conversion killer on mobile.”

+7 more findings

“PSI mobile score is 29/100. LCP of 33.8s and FCP of 11.8s are catastrophic for a $279.99 considered-purchase product — most cold mobile visitors will bounce before the page renders. CLS of 0.264 also indicates significant layout shift on load.”

+9 more findings

“No star rating, review count, or customer photo reviews are visible anywhere on the page in either screenshot. Zero social proof signals near the product title or CTA — a significant trust gap for a $39.99 accessory competing in a crowded phone case market.”

+7 more findings

“The 'ADD TO CART' button is present above the fold on mobile but does not appear to be sticky on scroll — once the user scrolls past the CTA zone, there is no persistent floating button visible in the lower thumb zone. The 'Recommended for you' and review sections appear with no sticky CTA anchoring the purchase.”

+9 more findings

“Star rating (4.79) and review count are visible near the product title on both mobile and desktop, which is good placement. However, only 19 reviews are shown — this is extremely low volume for a $129.99 electronics product and will undermine trust for cold visitors.”

+11 more findings

“Star rating (4.82/5) and review count (11 reviews) are visible near the product title on mobile — good placement. However, only 11 total reviews is a very thin proof base for a $99.99 electronics purchase. No customer photo reviews are visible; all reviews appear to be text-only with generic avatar placeholders. The 'As Seen On TV' badge is present but is an unspecific claim — no named press outlet (Forbes, GMA, etc.) is cited, though one review mentions 'GMA Discover the deal box' in the body text, which is not surfaced as a prominent trust signal.”

+8 more findings

“No video content is present anywhere on the page — no autoplay loop, no embedded demo, no thumbnail. For a tech product whose core value is invisible (background monitoring, app alerts), video is critical to explain the product and is entirely absent.”

+12 more findings

“Product name 'Photon Freedom Micro LED Keychain Flashlight, Black' is visible on mobile but sits below the fold — the hero image and volume discount table push it down, requiring a scroll before the name is readable.”

+9 more findings

“PSI mobile score is 31/100 with LCP of 15.1s and FCP of 9.7s — a cold mobile visitor waits over 9 seconds before seeing any content. TBT of 1,320ms means the page is unresponsive to taps for over a second after load. This is a conversion killer for a $79.99 impulse-adjacent electronics purchase.”
