Performance & Technology
Speed benchmarks, Core Web Vitals, and technology assessment for Aftermarket
Mobile PageSpeed Score
Mobile Lighthouse lab score is critical (27/100) — LCP 23.3s, FCP 5.5s, TBT 866ms. Desktop is also weak (40). However, CrUX field data tells a far better story (real-user LCP 1.7s, INP 153ms, all FAST), so the lab numbers reflect worst-case cold loads more than typical experience.

What This Means for Revenue
Aftermarket scores 27/100 on mobile and 40/100 on desktop in Lighthouse lab tests, with a punishing lab LCP of 23.3s. The silver lining: CrUX field data — real Chrome users over 28 days — shows LCP 1.7s, FCP 1.5s and INP 153ms, all in the FAST band, meaning returning users on warm caches have a solid experience and the lab test is hitting worst-case scenarios (heavy third-party scripts on a cold load). Competitors face the same mobile-performance gap: FinditParts (mobile 38, desktop 76) and RealTruck (mobile 29, desktop 65) also struggle on mobile lab scores, so disciplined mobile optimization is an opportunity to leapfrog the category. Iowa 80 was dropped from this comparison — it returned 403 to the PageSpeed API. Scores are Lighthouse LAB data; CrUX field figures are labelled separately.
Technology Stack
Platform
Shopify
Fully hosted Shopify store — PCI-compliant, auto-scaling infrastructure, 99.99% uptime SLA. Shop ID: 55206412439. myshopify domain: aftermarketus.myshopify.com.
Theme
Enterprise (Custom Copy)
- Type: Shopify Theme Store — Enterprise fork
- Theme: 'Updated copy of Enterprise' — schema v2.3.0, theme_store_id 1657. OS 2.0 compatible.
- Custom fork of Enterprise theme; hero section shows blank/empty viewport on mobile — possible JS render dependency on vehicle widget.
Checkout & Payments
Native Shopify Checkout via Shopify Payments (native)
- Guest checkout: Available via native Shopify checkout flow.
- Express checkout: Shop Pay, Apple Pay, Google Pay configured in payment settings but NOT surfaced in cart — only a single black 'Checkout' button visible in cart.
- Visa, Mastercard, American Express, Discover, Google Pay, Apple Pay, PayPal, Shop Pay — all visible in PDP Payment & Security section.
Technology Assessment
Aftermarket runs on a custom fork of Shopify's Enterprise theme (v2.3.0). Platform and security foundations are solid — Shopify Payments covers a full suite of US payment methods. The checkout flow is native Shopify but adds unnecessary friction via a mandatory terms checkbox and no express checkout buttons in cart. Performance is the primary technical risk: Lighthouse mobile lab score of 27/100 (LCP 23.3s) driven by unoptimized marketing images and 6 third-party script domains loading on every page — though real-user CrUX data (LCP 1.7s) indicates warm-cache performance is acceptable. Key gaps: BNPL not activated despite Shopify Payments eligibility, no session recording tool, and the vehicle fitment widget is powered by a custom app with a degraded single-dropdown mobile UX.
UX & Conversion Findings
Page-by-page analysis with visual comparisons against top Automotive Aftermarket Parts stores
- Typing into the search bar produces no dropdown — users must press Enter to see any results, adding an extra interaction step for every search.
- For automotive parts, predictive search is critical: a user searching '2019 Silverado air spring' needs to see part numbers and fitment suggestions before committing a search.
- The current search icon-only header requires 2 taps (icon then text field) before a user can even begin typing, adding further friction.
- 7/10 leading stores in the category provide real-time search suggestions including product names, part numbers, and category matches.
- Upgrade the XCloud Search & Filter app (already installed) to enable predictive autocomplete showing product names, part numbers, and categories as the user types — configure 3-character trigger threshold.
- Add vehicle fitment to search suggestions: when a user has selected their vehicle in the garage/fitment widget, prioritize compatible parts in search results and label them 'Fits Your Truck'.
- Ensure mobile search opens inline (not a redirect) with the keyboard auto-focused so users start typing immediately on one tap.
- The Air Springs collection (105 products) has only 2 filter options: 'Availability' and 'Collection' — there is no price range filter, no vehicle fitment filter, and no brand or part-type filter.
- For automotive aftermarket parts, fitment filtering (Year / Make / Model) is the single most critical navigation tool — buyers need to instantly see parts that fit their truck, not scroll 105 products manually.
- Without a price filter, a user looking for air springs under $150 must scroll the entire catalog; FinditParts and RealTruck both show dedicated price-range and fitment filters on collection pages.
- 9/10 leading stores in the category provide at least 3 filter categories including price range.
- Add a Year / Make / Model fitment filter as the primary filter on all part-category collection pages — when a user has selected their vehicle in the site's garage widget, auto-apply the fitment filter to show only compatible parts.
- Add a price-range slider (min/max input or drag handle) as a second filter — for a $50–$1,100 price range catalog, price filtering is a primary decision tool.
- Add a Brand filter (Torque, Firestone, etc.) as a third option — automotive buyers frequently search by OEM part replacement brand.
- Collection cards show image, brand name, product title, price with strikethrough, and an ATC button — but no indication of how many variants exist (e.g. '2 capacities: 5000/7500 Lbs') or vehicle compatibility.
- A buyer browsing Air Springs has no way to know from the collection grid whether a $103 card fits their truck — they must click into each PDP, check fitment, and back out if incompatible.
- For auto parts, a 'Fits: Chevy Silverado 1500 2019-2026' compatibility badge on the card would prevent wrong-vehicle clicks and reduce PDP bounce.
- 6/10 leading stores show variant count or compatibility indicators on collection cards, reducing unnecessary PDP clicks by 20–35%.
- Add a 'Fits [Vehicle]' badge on collection cards when the buyer has a saved vehicle — highlight compatible parts in teal/green to create a visual shortcut for fitment-confirmed buyers.
- Show variant count below the product title: '2 options' or '5000 / 7500 Lbs' so buyers know what configurations are available before clicking in.
- For multi-vehicle compatible parts, show a small compatibility indicator ('Fits 120+ trucks') to communicate breadth without detail.
- Aftermarket has a 4.9-star rating from 75 reviews — excellent social proof — but this appears only in a 'Recent Reviews' section far below the fold, not near the product title or price.
- The above-fold PDP area shows: fitment widget, breadcrumb, and product hero image. No star rating or review count is visible without scrolling down 4+ screens.
- For a $329 purchase decision, missing the review signal above fold means buyers who don't scroll never see the validation that could tip them to convert.
- 8/10 leading stores display star rating and review count directly below the product title, before the price.
- Add a Judge.me inline rating widget directly below the product title (or between title and price) — star icon plus rating number plus review count, all clickable to scroll to the reviews section.
- Consider a single-line format: 4.9 stars (75 reviews) — small enough to not disrupt the price area but powerful enough to establish trust at first glance.
- Ensure the rating widget loads with the page (not lazy-loaded) so it appears on mobile even at slow connections where only the first fold loads.
- The PDP shows only 'Add to Cart' with no 'Buy Now' or 'Buy It Now' option — high-intent buyers who know exactly what they need must navigate through cart before reaching checkout.
- For parts purchases over $300, customers who decide quickly want a direct path to checkout — the additional cart step creates an opportunity to abandon.
- Shopify natively supports a dynamic checkout button (Shop Pay, Apple Pay) that serves as a 'Buy Now' equivalent — this can be enabled in theme settings.
- 5/10 leading stores offer a Buy Now or express checkout path directly from the PDP alongside the standard ATC button.
- Enable Shopify's dynamic checkout button beneath the Add to Cart button — this renders as Shop Pay, Apple Pay, or Google Pay depending on the shopper's saved credentials, acting as a one-tap checkout.
- Label it clearly as 'Buy It Now' or keep it as the payment-brand button (Shop Pay logo) — both formats are recognized by US shoppers.
- Ensure the dynamic checkout respects the selected variant (capacity: 5000/7500 Lbs) before proceeding to checkout.
- The PDP has no shipping timeline near the ATC area — the only mention is in the announcement bar ('Free Shipping on All Orders Over $49') which disappears on scroll.
- Truck owners buying suspension kits often have a specific installation date in mind — knowing 'Ships in 1-2 days, arrives by Fri Jun 27' is a purchase-triggering signal, not just a nice-to-have.
- The announcement bar confirms free shipping over $49 (this cart qualifies at $329) but this is not repeated near the ATC, and there is no estimated arrival date anywhere.
- 6/10 leading stores display a delivery estimate (static or zip-code-based) within 200px of the ATC button.
- Add a static delivery estimate below the ATC button: 'Free shipping — typically arrives in 3-5 business days' or use a dynamic message based on current inventory location.
- Link to the full shipping policy from this message so concerned buyers can get detail without leaving the PDP.
- For same-day or next-day cutoff windows, add 'Order within X hours for [date] delivery' urgency messaging alongside the existing sale countdown timer.
- The 'Select Your Vehicle' widget renders only a single 'Select Make' dropdown, with a stray '1' in the field and no Year, Model, or Submodel steps — the fitment cascade is incomplete and non-functional on first load.
- Heavy-duty truck and pickup parts are fit-critical: shoppers cannot confirm a part fits their exact year/make/model/trim, which drives cart abandonment, wrong-fit returns, and avoidable support contacts.
- Leading auto-parts stores make a full Year → Make → Model → Submodel 'garage' selector the primary entry point and persist the chosen vehicle across the catalog; RealTruck confirms fitment directly on the product page.
- The widget appears in the same broken state site-wide (homepage, collection, PDP, cart), so the issue compounds at every step of the funnel.
- Complete the Year → Make → Model → Submodel cascade and fix the empty/placeholder field state so the selector works on first load.
- Persist the selected vehicle in a 'garage', filter the catalog to fitting parts, and show a 'Confirmed Fit for your {vehicle}' badge on the PDP near Add to Cart.
- Surface the selector above the fold on the homepage and collection pages as the primary navigation path for fit-driven shopping.
- The cart shows 'Taxes and shipping calculated at checkout' — there is no free shipping threshold bar despite the store offering free shipping on orders over $49.
- A $329 cart clearly qualifies for free shipping but the buyer has no cart-level confirmation of this — uncertainty about shipping cost is a top-3 cart abandonment driver.
- For carts just below $49 (plausible for small parts like filters or fittings), a 'Add $X more for FREE shipping' progress bar is a proven AOV driver that typically lifts basket size 8-15%.
- 5/10 leading stores display a free shipping progress bar in the cart summary area.
- Add a free-shipping progress indicator above the subtotal in the cart: a thin progress bar showing 'You qualify for FREE shipping' for carts above $49, or 'Add $X more for free shipping' for carts under.
- Configure the Vitals app (already installed) — it includes a built-in Free Shipping Bar widget that can be activated with threshold settings.
- Style the 'unlocked' state (above $49) in a celebratory green color to reinforce the buyer's decision with a positive signal before checkout.
- The cart shows only a single 'Checkout' button with no express checkout options — no Shop Pay, no Apple Pay, no Google Pay, no PayPal Express despite all being accepted payment methods on the site.
- On mobile, Shop Pay and Apple Pay express checkout reduce checkout to a single biometric confirmation — for a $329 purchase that could have been abandoned at address entry, this is a conversion-critical gap.
- The site has Shop Pay configured (visible in PDP payment icons) but this is not surfaced as an accelerated cart option.
- 5/10 leading stores show express checkout buttons (Shop Pay / PayPal / Apple Pay) directly in the cart above the standard Checkout button.
- Enable Shopify's dynamic checkout buttons in the cart template — in Shopify theme settings, these render Shop Pay, Apple Pay, and Google Pay as separate branded buttons above the standard Checkout CTA.
- Label the express section 'Express Checkout' above the payment buttons to set context, followed by a divider and the black Checkout button.
- Ensure the express checkout buttons respect the terms-agreement checkbox requirement — consider removing the checkbox to eliminate this friction.
- The cart order summary shows 'Subtotal: $329.99 USD' — the original price ($379.99) is shown on the line item but there is no aggregate savings line (e.g. 'You are saving $50.00 on this order').
- For a buyer who added a 13%-off suspension kit, seeing 'You are saving $50' as positive reinforcement before checkout nudges commitment — particularly for buyers considering abandonment.
- The cart item shows the strikethrough price ($379.99) and discounted price ($329.99), so the data is available — but the savings total is never surfaced at the summary level.
- 5/10 leading stores display a total savings line in the cart order summary when at least one discounted item is present.
- Add a 'You are saving: $50.00' line in green in the order summary section, between the item subtotal and the shipping/tax note.
- Configure the Vitals app's cart savings display feature (included in the app bundle already installed) to auto-calculate and show total savings.
- For multi-item carts, this becomes even more powerful — showing 'You are saving $125 on 3 items' creates a strong price-anchoring effect that reduces abandonment.

App Stack Assessment
Aftermarket's app stack is functional but under-optimized for a US automotive parts store. The Vitals suite (already installed and paid for) appears to have several high-value features unconfigured — free shipping bar, total savings display in cart, and potentially BNPL. The most critical gap is the absence of a robust vehicle fitment app: the custom YMM widget is single-dropdown only on mobile. Second highest-impact gap is the lack of an email/SMS automation platform (Klaviyo/Omnisend) — critical for abandoned cart recovery in a category with 3–7 day consideration cycles.
