BigCommerce Growth Agency
Stop leaving revenue on the table with BigCommerce store optimization
Your BigCommerce store is already getting traffic. The gap between current revenue and what your store can actually generate is an optimization problem. We close it.
Speed, conversion, catalog, and analytics: one team, one plan, one number to move. Yours.

The optimization gap
Most BigCommerce stores are running at half capacity
Not because the platform cannot perform. Because no single team owns the full picture. See what changes when someone does.
Fragmented ownership
Speed lives with your dev shop. Conversion rate optimization goes to a separate agency. Catalog is handled internally. No one connects the dots or owns the revenue outcome.
Guesswork over data
You know something is off because conversions are flat. But without BigCommerce-specific attribution, you cannot pinpoint which page, which flow, which fix.
Slow pages, lost revenue
Every 100ms of load time costs roughly 1% in conversion rate. Most stores we audit have LCP scores above 4 seconds on mobile. That is revenue bleeding daily.
Catalog confusion
Customers cannot find what they came for. Product categories overlap. Filters lead to dead ends. A catalog structure problem disguises itself as a traffic problem.
Reports arrive too late
Monthly agency decks arrive three weeks after the fact. By the time you read about a spike or a drop, the moment to act on it has passed entirely.

Inside every engagement
Your optimization engine, live
Every sprint runs through a structured loop: audit, prioritize, implement, measure, repeat. The mock to your right shows what a real store dashboard looks like inside our performance hub.
1
Speed audit and Core Web Vitals baseline
We measure every critical page against Largest Contentful Paint, First Input Delay, Cumulative Layout Shift, and Interaction to Next Paint targets. Your existing apps, scripts, and images get a line-by-line review before any code changes.
2
Commerce and catalog architecture review
Category depth, faceted navigation logic, product template structure, and cross-sell placement are mapped against your top revenue paths. We find where buyers drop before they reach the cart.
3
Conversion and checkout sprint
From add-to-cart call-to-action copy to guest checkout field reduction, every friction point in your funnel gets a fix with a measurable conversion hypothesis attached to it.
4
Analytics, attribution, and loop closure
GA4 and Klaviyo are aligned. Every optimization generates a measurable outcome that feeds the next sprint. The loop compounds over 90 days and beyond.
Most stores see a measurable lift within the first 30-day sprint. Growth compounds through 90 days as speed, catalog, and conversion improvements reinforce each other.

How optimization works
The Redefine optimization engine
Four layers that each reinforce the others. Select any layer to see what happens inside. Speed gains improve search engine optimization and conversion. Catalog improvements reduce bounce and lift average order value. Better data makes every next sprint smarter.
Layer 01

LCP target: under 1.8s on mobile
First Input Delay / Interaction to Next Paint: under 50ms
CLS: under 0.05 on all template types
Image pipeline: WebP, AVIF, responsive srcset
Impact: every 100ms faster is approximately 1% conversion

Why Redefine
Not all optimization partners look the same under the hood
Most agencies optimize one layer and call it done. Some do speed. Some do conversion rate optimization. Few own the full revenue outcome across all four. Here is what that difference looks like in practice.

Common questions
Everything you need to know before your first call
BigCommerce store optimization covers four interconnected areas: site speed and Core Web Vitals tuning, conversion rate and checkout optimization, catalog and navigation architecture, and analytics and attribution setup. Each sprint is tied to measurable key performance indicators so you see exactly which change moved which metric. Explore the full scope on our BigCommerce Audit Services page.
Speed and technical improvements show measurable impact within the first two to four weeks. Conversion and catalog changes take 30 to 60 days to generate statistically reliable data. Most clients see compounding growth by the end of the first 90-day sprint as speed, catalog, and conversion improvements reinforce each other.
A conversion rate optimization engagement focuses primarily on conversion testing. Store optimization is broader: it includes speed, catalog structure, app ecosystem health, and analytics alongside conversion work. These layers compound, so a speed fix also lifts conversion rates, and better catalog architecture improves both search engine optimization and checkout flow. See our dedicated BigCommerce Conversion Rate Optimization Services if you need a conversion-only scope.
Yes. Redefine works with both Stencil-based themes and BigCommerce Page Builder setups. Our optimization includes theme-level script audits, CSS reduction, and render-blocking resource resolution specific to the BigCommerce frontend architecture. If your theme needs a rebuild rather than optimization, see BigCommerce Web Design Agency.
The audit covers Core Web Vitals against your top 10 pages, checkout funnel drop-off analysis, app and script bloat review, catalog and navigation depth mapping, and GA4 and attribution accuracy. You receive a prioritized action list with estimated revenue impact for each recommendation. See the full scope on our BigCommerce Audit Services page.

Honest about who we build results for
Store optimization is a compounding commitment, not a one-time fix. We do our best work with teams ready to measure and iterate.
Good fit for...
- Stores with consistent traffic that are not converting at the rate the traffic volume should support
- Teams who want a single accountable partner across speed, catalog, conversion, and analytics
- Operators growing toward or past $1M annual revenue who need structured sprint methodology
- Brands with BigCommerce stores where Core Web Vitals, catalog structure, or checkout friction are limiting revenue
Not a fit if...
- You are pre-launch or have fewer than 500 monthly sessions (not enough data for optimization to compound)
- You need a single one-off fix with no ongoing measurement or sprint loop
- Your primary challenge is paid traffic acquisition, not store conversion or retention
- You need a complete platform migration before optimization work can begin
