E-commerce engineering that turns traffic into revenue.

Faster checkouts, programmatic category pages, lifecycle that converts.

Storefront performance is conversion. Programmatic SEO is your unit-economics weapon. Lifecycle email is your retention floor. Sage Ideas builds the engineering layer underneath your DTC brand — Shopify Hydrogen or custom Next.js, Stripe and Shop Pay, Klaviyo flows, and the Core Web Vitals discipline that compounds into measurable revenue lift.

Why us

Why Sage Ideas for E-commerce

Core Web Vitals as a revenue metric — every 100ms of LCP improvement is measurable conversion lift, and we instrument before and after so you can prove it to the CFO.
Programmatic SEO for SKU, category, collection, and "best [product] for [use-case]" pages — the long-tail traffic that compounds without paid spend.
Shopify Hydrogen, Liquid, and headless Next.js — we will tell you honestly which fits your catalog size, content velocity, and team.
Checkout funnel optimization with real instrumentation — payment method drop-off, address validation friction, "why did 30% of users abandon at shipping?" answered with data, not guesses.
Lifecycle email and SMS architecture in Klaviyo or Customer.io: abandoned cart, browse abandonment, win-back, post-purchase, and replenishment flows that match real LTV math.
Stripe and Shop Pay integration including subscriptions, gift cards, store credit, and the inevitable "can we accept Apple Pay on the PDP?" — yes, and here is how.
Challenges

What we solve

The specific operational challenges we've already debugged in the e-commerce stack.

A storefront that loads in 4 seconds on mobile

Hero videos that block render, third-party scripts that ship 800KB of JS, image sizes that ignore device pixel ratio. We profile the real waterfall, prioritize LCP-blocking resources, and ship a budget that the next marketing team cannot accidentally blow.

Category pages with no SEO depth

Your category pages are template stubs with no copy, no FAQ, no buyer guides, no cross-links. They cannot rank for "[product] for [use-case]" queries that drive intent traffic. We build the programmatic content infrastructure that makes every collection a destination.

Abandoned-cart flows that send three generic emails

No segmentation by cart value, no urgency signals, no SMS fallback, no win-back tier. Every abandoned cart is treated the same. We architect the lifecycle layer in Klaviyo with branching logic tied to LTV cohorts and product margin.

Checkout drop-off with no instrumentation

You know cart-to-checkout rate but not which specific field, validation error, or payment method is killing conversion. We instrument every interaction in checkout, find the highest-friction step, and ship the fix in days — not after a six-month rebuild.

FAQ

E-commerce questions

Hydrogen, Liquid, or headless Next.js — which should we use?

Liquid (Online Store 2.0) is the right answer for most brands under $10M GMV with a small dev team. It is fast enough, the merchant tooling is unmatched, and you do not need a build pipeline. Hydrogen makes sense once you outgrow Liquid sections and need React-level component reuse, custom checkout extensions, or aggressive personalization. Headless Next.js fits when commerce is a small piece of a larger content site, you have non-Shopify catalog sources, or the brand needs marketing pages a CMS can power without engineering. We will recommend the option your team can actually maintain.

How do you build programmatic SEO for SKU and category pages?

Templates fed from structured product data, with each page earning its uniqueness through real differentiation — actual specs, actual reviews, actual buyer use-cases, FAQ schema, and internal links to comparison and accessory pages. We index gradually, monitor Search Console for thin-content flags, and prune underperforming URLs. The goal is a long-tail moat — pages ranking for "[product] for [persona]" and "[product] vs [competitor]" queries that paid search cannot economically serve.

What is your Core Web Vitals approach?

Measure first with field data from Chrome UX Report and your real users (RUM via Vercel Speed Insights or Cloudflare Web Analytics), not lab tools. The biggest LCP wins are usually image format and dimensions (next/image with proper sizes, WebP or AVIF), critical CSS, and removing render-blocking third-party scripts. CLS comes from web fonts and ad slots without reserved height. INP comes from heavy event handlers and React hydration cost. We profile, fix, and re-measure in production.

Can you build abandoned-cart and lifecycle flows in Klaviyo?

Yes — and the architecture matters more than the copy. We segment by cart value, product margin, and customer LTV cohort, then branch flows accordingly: a $30 abandoned cart from a first-time buyer gets a different sequence than a $400 abandoned cart from a repeat customer. SMS fallback is wired in for high-LTV cohorts where economics support it. Win-back, post-purchase replenishment, and browse-abandonment flows all run from the same event spine.

Do you do paid media and creative, or just engineering?

Engineering and SEO/content are our core. We do not run Meta or Google Ads campaigns ourselves — that is a different discipline and we have agency partners we trust. What we do is build the landing page infrastructure, instrument the conversion events correctly (server-side via Conversions API or GA4 Measurement Protocol), and make sure your media buyers are optimizing on signal that actually predicts revenue.
