Every ecommerce brand is leaving revenue on the table somewhere. Small stores leave a lot; large stores leave less as a percentage but more in absolute dollars. The only way to know where is to run a systematic audit across every layer of the operation. This is the same 7-layer framework we use as an ecommerce consultant on paid engagements — you can run it yourself, or hire us to do it.
Layer 1: Shopify technical health
Start with Core Web Vitals in Google Search Console and PageSpeed Insights. LCP under 2.5s, CLS under 0.1, INP under 200ms. If you're failing any of these on mobile (where most traffic lives), every other marketing dollar is under-performing.
Audit your installed apps — most Shopify stores carry 10–20 apps, half of which are unused or redundant. Each app adds JS weight and can slow the storefront. Uninstall aggressively.
Check your theme for outdated versions, custom code from previous developers, and abandoned page templates. Confirm sitemap.xml is current, robots.txt isn't blocking anything important, and every indexable page has a canonical tag.
Layer 2: Paid media
Open each ad platform (Google Ads, Meta Ads Manager, TikTok Ads Manager) and audit:
- Campaign structure — are campaigns segmented correctly by intent and audience?
- Creative — how many active creatives per ad set, when was each last refreshed?
- Targeting — over-restrictive audiences that limit algorithm learning?
- Attribution — click vs view, attribution windows, blended ROAS vs platform-reported ROAS
- Feed health (Google Shopping) — disapproved products, missing attributes, price/stock sync
Benchmark blended ROAS against category norms — 3–6x is typical for scaling DTC brands. If you're below 2x, either the media, the offer, or the funnel is broken.
Layer 3: Organic SEO
In Google Search Console: which pages have declining impressions? Which queries have declining rankings? For ecommerce, focus on product and collection pages first — blog performance is nice but rarely moves the P&L.
Technical SEO: check for crawl waste (faceted navigation creating infinite URL variations), missing or duplicated schema markup on product pages (Product, Review, FAQPage), and internal linking health from collection pages to key products.
Content SEO: run a competitive gap analysis for the top 20 category-defining keywords. If competitors have content that ranks and you don't, that's a documented opportunity.
Layer 4: GEO/AEO (AI search visibility)
Ask ChatGPT, Perplexity, and Google AI Overviews recommendation-style questions in your category — "best luxury fragrance for men," "top wholesale Italian leather suppliers." Are you cited? Are your competitors? Track this monthly.
For visibility fixes: implement Product, Organization, and FAQPage schema, publish long-form content that answers procurement-style questions directly, and build brand entity signals through consistent NAP data, Wikipedia references where applicable, and citations from authority sources.
Layer 5: Email marketing
In Klaviyo, check attributed revenue as a percentage of total revenue. Mature ecommerce brands hit 25–40%. If you're under 15%, you're under-monetizing your list — usually because flows are missing, not because campaigns are bad.
Audit the 5 core flows: welcome, abandoned cart, browse abandon, post-purchase, and win-back. Every one should exist, be revenue-attributed, and have been updated within the last 6 months. Deliverability (open rate, spam complaint rate) tells you if list hygiene is a problem before revenue does.
Layer 6: Conversion rate optimization (CRO)
Open GA4 and look at conversion rate by device and traffic source. Mobile should be within 30% of desktop; if it's 50%+ lower, you have a mobile UX problem. Paid traffic should convert similarly to organic; if it doesn't, your landing pages don't match your ads.
On product pages: images (multiple angles, zoom, lifestyle), reviews (present, quantity, quality), trust signals (returns, guarantees, shipping), and above-the-fold buy box. On checkout: number of steps, guest checkout availability, payment methods, and shipping cost transparency.
Layer 7: Competitive landscape
For the top 5 competitors in your category: pricing vs yours, review quantity and rating, ad creative rotation (via Meta Ad Library), SEO ranking overlap (via Ahrefs or Semrush), and any notable UX advantages. This context turns your findings into "what to prioritize" — you can't fix everything, but you should fix what competitors are winning on.
Prioritizing what to fix
Every finding should be scored on impact vs effort. Big-impact/low-effort items go first — usually things like broken email flows, feed disapprovals in Google Shopping, or a checkout with an unnecessary field. Big-impact/high-effort items (site migration, full CRO program) go on the 6-month roadmap. Low-impact items stay documented but don't get done.
When to hire a consultant vs do it yourself
DIY audit works if you have the internal capacity and the cross-functional expertise. It falls apart when the audit needs to cover disciplines you don't practice — most in-house teams are strong in 2 of the 7 layers and weak in the rest.
A paid audit from an ecommerce agency or ecommerce marketing agency with real specialist coverage is worth it when the diagnosis matters (before a big investment, after a plateau, during hiring), and when internal politics prevent honest cross-team assessment.
For B2B wholesale brands, the audit framework is different — reorder rate, portal adoption, and account expansion metrics matter more than one-time conversion rate. Our B2B ecommerce agency team runs a B2B-specific audit for those engagements.
The bottom line
An ecommerce audit is unglamorous work that consistently produces the highest ROI of any single consulting engagement. Every hour spent finding a leak saves ten hours of wasted execution later. Whether you run this framework yourself or hire us, the audit is where growth actually starts.
