Every brand, scored.

“PSI mobile score is 32/100 with an LCP of 31.7s and FCP of 9.0s — catastrophic load times for a cold mobile visitor. TBT of 1,150ms means the page is unresponsive for over a second after it begins loading. This will cause significant bounce before the page is even interactive.”

“PSI mobile score is 27/100 with LCP of 16.0s, FCP of 7.3s, and TBT of 2,010ms. A 16-second largest contentful paint means a cold first-time mobile visitor is staring at a blank or partial screen for over 15 seconds before the hero image loads — this alone will kill conversion for paid traffic.”

“PSI mobile score is 31/100 with an LCP of 32.8s and FCP of 30.2s — catastrophically slow cold load. TBT of 1,200ms means the page is unresponsive for over a second after paint. A first-time mobile visitor on a typical connection will stare at a blank or partially loaded screen for 30+ seconds before the hero image resolves.”

+7 more findings

“PSI mobile score is 21/100 — critically poor. LCP of 6.0s means the hero image takes 6 seconds to load on a cold mobile visit. TBT of 1,250ms indicates heavy JavaScript blocking the main thread. CLS of 0.335 is well above the 0.1 threshold, meaning the page visually shifts significantly during load — this will cause mis-taps on the CTA and variant selectors. This is the single most damaging technical issue on the page.”

+8 more findings

“There is no sticky Add to Cart button visible on mobile scroll. The CTA area is buried deep in the page after the bundle builder — users must scroll through 15+ flavor variant rows before reaching the purchase action. The green 'SAVE 25% EVERY MONTH' bar at the bottom of the mobile screenshot is not a tappable CTA. No persistent sticky button is observed.”

+9 more findings

“The 'Add to Bag' button on mobile appears below a long variant/subscription selection block — it is not sticky on scroll based on the screenshot. A first-time mobile visitor must scroll past serving size options, purchase type toggle, subscription details, and quantity selector before reaching the CTA, with no persistent sticky button visible.”

+10 more findings

“PSI mobile score is 51/100 with an LCP of 28.0 seconds and FCP of 12.3 seconds. These are critically slow load times for a cold mobile visitor — the page will appear blank or partially rendered for over 12 seconds on a typical mobile connection, causing significant bounce before the product is even seen.”

+7 more findings

“PSI mobile score is 45/100 with an LCP of 35.6 seconds and FCP of 10.5 seconds — catastrophically slow cold load. A first-time mobile visitor waits over 10 seconds before seeing any content, and the largest element takes 35+ seconds to render. TBT of 410 ms adds further interaction delay.”

+7 more findings

“On mobile, the product name 'Postnatal Complete Bundle' and subtitle 'DAILY ESSENTIALS FOR POSTPARTUM' appear below the image carousel and review stars — requiring a scroll before the name is fully readable. Price ($97.18 subscribe / $107.98 one-time) is also below the fold on mobile.”

+11 more findings

“Product name 'COLLAGEN PEPTIDES PROTEIN POWDER' is visible above the fold on mobile but only after a large blank image area dominates the viewport — the hero image appears to fail loading or render off-screen, leaving a dead white zone before the product name appears near the bottom of the fold. Price ($33.59) is visible in the sticky Add to Cart bar at the bottom, not prominently near the product title.”

+9 more findings

“The Subscribe & Save toggle defaults to subscription at $35.99 with the CTA reading 'Add subscription to cart.' A cold visitor who wants a one-time purchase must actively notice and select the separate 'One-time purchase $44.99' row below. This default-to-subscription pattern adds friction and potential cart abandonment for non-subscribers.”

+11 more findings

“No customer photo reviews or UGC are visible anywhere in either screenshot. No 'As Seen In' press bar, named media mentions (e.g., Men's Health, Forbes), or third-party certification badges (beyond the on-label 'Truly' badge) are shown on the page. The 'THIRD-PARTY CERTIFIED' checkmark is present but no certifying body is named, reducing trust impact.”

+11 more findings

“PSI mobile score is 22/100 with LCP of 24.9s, FCP of 22.4s, CLS of 0.498, and TBT of 480ms. A 24.9s LCP means most cold mobile visitors will abandon before the hero image fully loads. The CLS of 0.498 is nearly 5x the 'good' threshold, meaning the page visibly jumps as it loads.”

+7 more findings

“No customer photo reviews or UGC are visible on the page. The single featured review from 'Jay' is text-only. Photo reviews from real customers would materially increase purchase confidence for a supplement at $48/month.”

+12 more findings

“PSI mobile score is 29/100 with LCP of 15.7s and FCP of 6.3s — a cold first-time visitor on mobile waits over 6 seconds to see any content and over 15 seconds for the main image to load. TBT of 1,560ms means the page is heavily blocked during load. This is a critical conversion killer for paid traffic.”

+7 more findings

“Star rating (5 stars) and review count (351) are visible near the product title on both mobile and desktop — well-placed. 351 reviews earns 3 pts for volume (100–999 range). However, no customer photo reviews or UGC are visible on the page in the screenshots, and no press mentions, 'As Seen In' bar, or named certifications appear anywhere on the page.”

+7 more findings

“PSI mobile score is 53/100 with an LCP of 23.1 seconds and FCP of 8.9 seconds. These are critically slow load times for a cold mobile visitor — a 23-second LCP means the hero image is not rendered for nearly half a minute on a typical mobile connection, which will cause significant bounce before the page is even seen. TBT of 170ms is acceptable but the FCP and LCP figures are the dominant conversion killers here.”

+7 more findings

“PSI mobile score is 29/100 with LCP of 17.6s and TBT of 1,490ms. A cold first-time mobile visitor waits over 17 seconds for the largest content element to paint — this alone will kill conversion before the page is even seen.”

+7 more findings

“PSI mobile score is 26/100 with LCP of 13.2s, FCP of 6.9s, and TBT of 3,200ms. A first-time cold mobile visitor waits over 13 seconds to see the main product image — this alone will kill a significant share of paid traffic before the page even loads.”

+7 more findings

“No customer photo reviews or UGC are visible anywhere in the screenshots. For a detox/transformation product at $185, before-and-after photos or customer selfies with results copy are a critical trust lever that is entirely absent from the visible page.”

+11 more findings

“PSI mobile score is 39/100 — LCP of 25.7s and FCP of 13.5s are catastrophic for cold mobile visitors. A first-time user on a typical mobile connection will stare at a blank or partially loaded screen for over 13 seconds before seeing any content. TBT of 480ms also signals heavy main-thread blocking.”

+7 more findings

“Only 2 images are visible in the mobile carousel (indicated by 2 dots below the hero image) — one product shot and one lifestyle image of a man in a kitchen. Desktop thumbnail rail shows only 2 images as well. For a $65–$70 supplement product, this is a critically thin image gallery; no ingredient callout images, no flat-lay, no in-hand shots.”

+12 more findings

“Star rating (5 stars) and '74 reviews' count are visible near the product title on mobile — good placement. However, 74 reviews scores only 2 pts on the volume rubric (11–99 range), and no customer photo reviews or UGC are visible anywhere on the page in either screenshot.”

+11 more findings

“A 'GET 15% OFF!' sticky bar appears at the bottom of both mobile and desktop screenshots, which competes visually with the 'Add to Cart' CTA and could confuse users about which action to take. The Add to Cart button is present and prominent on mobile but the sticky discount bar partially obscures the thumb zone.”

+8 more findings

“PSI mobile score is 33/100 with LCP of 16.7s and FCP of 7.1s — a cold first-time visitor on mobile waits over 7 seconds before seeing any content. TBT of 1,140ms means the page is heavily blocked during load. This is a critical conversion killer for paid traffic.”

+7 more findings

“PSI mobile score is 25/100 — critically poor. LCP of 20.6 seconds and FCP of 7.7 seconds mean a cold mobile visitor on an average connection will stare at a blank or partially loaded screen for 7+ seconds before seeing content. TBT of 6,110 ms indicates severe JavaScript blocking that makes the page feel unresponsive to taps. This is the single most damaging conversion issue on the page.”

+9 more findings

“PSI mobile score is 0/100 with FCP of 6.8s and CLS of 0.13. LCP and TBT are not available, indicating a likely render-blocking failure. A 6.8s first contentful paint means most cold mobile visitors will bounce before the page loads.”

+7 more findings

“PSI mobile score is 22/100. LCP of 9.8s and FCP of 4.4s mean most first-time mobile visitors are staring at a blank or partial screen for nearly 10 seconds before the hero image loads. CLS of 0.324 causes visible layout shift as assets load, and TBT of 790ms makes the page feel unresponsive to taps.”

+7 more findings

“PSI mobile score is 34/100 with an LCP of 29.4s and FCP of 8.5s — both catastrophically slow for a cold mobile visitor. CLS of 0.406 means the page visibly shifts as it loads, which will cause mis-taps on the Add to Cart button. This is the single biggest conversion killer on the page.”

+9 more findings

“PSI mobile score is 26/100 with LCP of 27.8s, FCP of 6.3s, and TBT of 4,130ms. A 27-second largest contentful paint means the hero image is effectively invisible for most first-time mobile visitors on average connections. This is a critical load failure.”

+7 more findings

“PSI mobile score is 35/100 with an LCP of 35.3 seconds and FCP of 7.5 seconds — catastrophically slow for a cold mobile visitor. TBT of 910 ms means the page is unresponsive for nearly a full second after load. This will cause significant bounce before the page is even interactive.”

+7 more findings

“PSI mobile score is 10/100. LCP of 26.6s and FCP of 13.1s mean most first-time mobile visitors will stare at a blank or partially loaded screen for over 13 seconds before seeing content. CLS of 0.837 indicates severe layout shift — elements visibly jump as the page loads. TBT of 960ms signals heavy JavaScript blocking the main thread.”

+7 more findings

“PSI mobile score is 43/100 — below the 50-point threshold, earning 0 pts. LCP of 41.5 seconds is catastrophic; a cold mobile visitor will stare at a blank or partially loaded page for over 40 seconds before the largest content element renders. FCP of 7.3 seconds means even the first paint is severely delayed.”

+10 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 (e.g., Informed Sport, NSF) are present. The only trust signal is the star rating block, leaving significant credibility on the table for a supplement brand where third-party validation is critical.”

+8 more findings

“Product name 'LMNT Zero-Sugar Electrolytes' is partially cut off on mobile by the cookie consent banner, making it unreadable above the fold without dismissing the overlay. Price ('$1.50 / Stick') is not visible on mobile above the fold at all — it only appears on desktop.”

+10 more findings

“Product name 'Protein Bars' and price '$34.99' are both visible above the fold on mobile, but the hero value proposition is missing above the fold. The headline 'TASTES LIKE A CANDY BAR' only appears below the fold in a marquee/scrolling text section — a first-time visitor must scroll to encounter any differentiated claim.”

+9 more findings

“PSI mobile score of 17/100 is catastrophic: LCP 18.1s, FCP 8.4s, CLS 0.387, TBT 850ms. A first-time cold visitor on mobile will stare at a blank or partially loaded screen for 8+ seconds before seeing any content. This alone will kill a significant share of paid traffic.”

+7 more findings

“PSI mobile score is 36/100 — LCP of 9.3 seconds and TBT of 1,020 ms are critically poor. A first-time cold mobile visitor will wait nearly 10 seconds to see the main product image, which will cause significant bounce before any conversion signals are even rendered.”

+8 more findings

“No star rating or review count is visible anywhere near the product title or above the fold on mobile or desktop. The only social proof visible in the screenshots is a single athlete quote from Michael Chandler (UFC Lightweight Fighter) at the bottom of the desktop view and three trust badges ('Backed by 10X medical experts', 'CLIA Certified', '100% private data'). CLIA Certified is a meaningful credential but is presented as a small checklist item rather than a prominent trust signal.”

+9 more findings

“Only 7 reviews are shown next to the star rating. With just 7 reviews, trust is extremely thin for a supplement purchase — a cold visitor has almost no social validation to lean on. No customer photo reviews or UGC are visible anywhere on the page.”

+7 more findings

“The 'ADD TO CART' button is a large gold/yellow full-width button visible on mobile without scrolling past the purchase module, but it does NOT appear to be sticky on scroll — once the user scrolls into the 'About The Product' section, the CTA disappears. No persistent sticky bar is observed in the mobile screenshot.”

+9 more findings

“PSI mobile score is 34/100 with an LCP of 40.2 seconds and FCP of 6.8 seconds — catastrophically slow cold load. TBT of 930 ms signals heavy JavaScript blocking the main thread. A first-time mobile visitor on a typical connection will stare at a blank or partially loaded screen for 6+ seconds before seeing any content.”

+7 more findings

“No sticky Add to Cart button is visible on mobile scroll. The page uses a stepped selection flow (Step 1: Packaging, Step 2: Quantity, Step 3: Offer) which pushes the actual purchase CTA far below the fold. There is no persistent bottom bar with a buy button visible in the mobile screenshot, meaning a user must scroll through all three steps before they can tap to purchase.”

+8 more findings

“Product name 'Probiotic Complex' is visible above the fold on mobile and the 'BEST SELLER' badge adds credibility, but there is no hero headline or value proposition — no sentence answering 'why this probiotic, why now.' The product name alone does not differentiate from dozens of competitors.”

+7 more findings

“PSI mobile score is unavailable, so 0 pts are assigned for the first 10-pt block. Desktop PSI shows TBT of 3,980 ms — an extremely high blocking time that strongly suggests the mobile experience suffers from heavy JavaScript execution, likely impacting interactivity and perceived load speed for cold mobile visitors.”

+7 more findings

“Subscribe & Save toggle is present with a clear 'Save up to 10%' callout and the discounted price ($40.49) shown inline — this is well-executed. Free Shipping Over $100 is visible directly below the CTA. HSA/FSA eligibility is called out with a 'Learn more' link, which is a differentiating trust signal. Return/guarantee policy is not visible anywhere near the CTA on mobile — no money-back guarantee or return window is stated on the page.”

+7 more findings

“The 'ADD TO CART' button is visible at the bottom of the mobile screenshot but does not appear to be sticky on scroll — the button is only present at its natural page position. A first-time visitor scrolling through the long bullet list and subscription options has no persistent CTA anchor.”

+9 more findings

“PSI mobile score is 37/100 with an LCP of 26.4s and FCP of 8.3s — a first-time mobile visitor waits over 8 seconds before seeing any content. TBT of 700ms means the page is unresponsive to taps for nearly a second after load. This is a critical conversion killer in a competitive supplement category.”

+7 more findings

“The product page displays '0 Reviews' with an empty star rating directly below the product title on both mobile and desktop. This is a critical trust killer — the page has no reviews for Oxy-Powder itself, even though the Frequently Bought Together section at the bottom of the desktop screenshot shows 10,909 reviews for Oxy-Powder. Those reviews are not surfaced on the product page itself, making the product appear unreviewed to any visitor who doesn't scroll far down.”

+7 more findings

“PSI mobile score is 35/100 with LCP of 15.1s and FCP of 6.9s — a cold mobile visitor waits over 6 seconds to see any content and over 15 seconds for the main image to load. TBT of 910ms means the page is unresponsive to taps for nearly a full second after load. This is a critical conversion killer.”

+7 more findings

“There is no sticky Add to Cart button anywhere on the collection page — not on mobile, not on desktop. The only purchase path is tapping a product card to navigate to an individual PDP. This adds a full extra click/page load before a visitor can even see an Add to Cart button, significantly increasing drop-off risk.”

+8 more findings

“All visible images are isolated product shots on a plain grey/white background — front of can, back of can, nutrition label. There is zero lifestyle imagery showing the drink in use, in hand, at the gym, or in a social setting. The can label art is vibrant but the page staging is sterile.”

+9 more findings

“A scrolling testimonial strip with 5-star ratings is visible on both mobile and desktop, but there is NO aggregate star rating or review count shown near the product title. The reviews shown are all attributed to 'Anonymous' (mobile) or first-name-only (desktop: Linda J., John R.), which reduces credibility. No photo reviews or UGC are visible in either screenshot.”

+8 more findings

“Star rating (3.88 out of 5) and review count (58) are visible near the top of the page on both mobile and desktop — good placement. However, 3.88 stars is a below-average rating for the supplement category where top performers typically show 4.5+, and 58 reviews is a low volume that may undermine trust.”

+9 more findings

“No star rating or review count is visible anywhere near the product title on mobile or desktop above the fold. There is a 'Reviews' tab visible on the right edge of the desktop screenshot, but no inline star rating widget beneath the product name — a standard trust signal that is entirely absent from the primary purchase zone.”

+12 more findings

“Product name 'Animal Creatine Chews' is large and readable above the fold on mobile. Star rating (4.9, 257 reviews) and a short benefit-led description ('5g of creatine monohydrate per serving to support strength, performance, muscle growth, recovery, and cognitive function') are all visible without scrolling. However, the price is completely absent — no dollar amount appears anywhere on the page above or below the fold in either screenshot. This is a critical clarity gap.”

+7 more findings

“Desktop thumbnail rail shows only 3 product images (all appear to be pack shots / label variants — no lifestyle imagery visible). Mobile shows a single hero product shot with dot indicators suggesting 2 images. No video content is present anywhere on the page. There are zero lifestyle images showing the product in use (e.g., someone mixing it into a drink, active person, beauty context). All imagery is white-background product photography only.”

+7 more findings

“Free shipping threshold ('FREE SHIPPING ON ALL ORDERS OVER $99') is shown in the announcement bar at the top of the page on mobile. However, at a $36.99 price point, the customer is $62 away from free shipping with no bundle prompt or 'add X more for free shipping' nudge — this gap creates friction and likely increases cart abandonment.”

+9 more findings

“No video content is visible anywhere on the page — no autoplay loop, embedded video, or video thumbnail. For a supplement with an educational angle ('What is colostrum?'), video would significantly reduce skepticism.”

+11 more findings

“Only 46 reviews are shown, which scores in the 11–99 range. For a $42.95 supplement competing in a crowded digestive health category, this volume is low and may undermine trust. No customer photo reviews or UGC are visible anywhere in the screenshots.”

+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 are present. The trust badges shown ('100% Quality', 'Free Shipping', '30 Days Money Back Guarantee') are generic icon badges — not named press or third-party certifications.”

+10 more findings

“PSI mobile score is 42/100 with an LCP of 37.8s and FCP of 9.6s — catastrophically slow cold load. A first-time mobile visitor waits nearly 10 seconds before seeing any content and nearly 38 seconds for the largest element. TBT of 520ms adds further interaction delay.”

+7 more findings

“PSI mobile score is 29/100 with LCP of 15.1s, FCP of 5.3s, and TBT of 1,670ms. A 15-second largest contentful paint means the majority of cold mobile visitors will bounce before the page is usable. This is a critical revenue leak.”
