Every 100ms Your Frontend Wastes Costs You 7% in Conversions

Akamai research proves speed equals revenue. We optimize Core Web Vitals through code splitting, lazy loading, image optimization, rendering strategy changes, and bundle analysis that cut your load times by 50 to 80 percent.

7%

conversion rate reduction per 100ms of frontend load time delay, making performance optimization one of the highest-ROI frontend investments

What's Included

Everything you get with our Frontend Performance Optimization

Performance Audit with Prioritized Recommendations

Lighthouse audit, bundle analysis, waterfall analysis, and Core Web Vitals breakdown with each issue prioritized by conversion impact

Optimization Implementation

Code splitting, lazy loading, image optimization, font subsetting, critical CSS extraction, and rendering strategy changes implemented and measured

Performance Monitoring and Budget Enforcement

Lighthouse CI in your pipeline that blocks deployments exceeding performance budgets, plus real-user monitoring for ongoing visibility

Our Frontend Performance Optimization Process

1

Performance Audit

We run Lighthouse, analyze JavaScript bundles with source maps, review the network waterfall, and measure each Core Web Vital. We identify every bottleneck and estimate the conversion impact of fixing each one.

2

Prioritized Optimization

We implement optimizations in priority order: the changes with the highest conversion impact first. Each optimization is measured independently with before-and-after metrics.

3

Rendering Strategy Review

We evaluate whether your rendering strategy is optimal. Pages that should be statically generated might be server-rendered. Components that should be lazy loaded might be in the initial bundle. We restructure rendering for maximum speed.

4

Performance Budget and Monitoring

We configure Lighthouse CI with performance budgets in your CI/CD pipeline and set up real-user monitoring. Your team gets ongoing visibility into performance and automatic prevention of regression.

Key Benefits

Measurable conversion rate improvement

Every 100ms we cut from your load time recovers 7 percent of lost conversions according to Akamai. A typical optimization engagement cuts 1 to 3 seconds, which translates to 15 to 40 percent more conversions from the same traffic.

Better search engine rankings

Core Web Vitals are a Google ranking factor. Improving LCP, CLS, and INP directly improves your search visibility. Sites that pass Core Web Vitals thresholds appear higher in search results and earn more organic traffic.

Performance budgets that prevent regression

We configure Lighthouse CI in your pipeline to block deployments that exceed performance budgets. Your site cannot silently get slower. Performance improvements are permanent, not temporary.

Research & Evidence

Backed by industry research and proven results

The State of Online Retail Performance

A 100ms delay in load time can hurt conversion rates by 7%, making frontend performance directly tied to revenue

Page Load and Conversion

A site that loads in 1 second has a 3x higher conversion rate than one loading in 5 seconds

Frequently Asked Questions

How much faster can our site get?

Most sites with no prior optimization see 50 to 80 percent load time reduction. Sites that already have some optimization typically see 20 to 40 percent improvement. We provide specific projections after the initial audit based on your site's actual bottlenecks.

What are Core Web Vitals?

Three metrics Google uses to measure user experience: Largest Contentful Paint (loading speed), Cumulative Layout Shift (visual stability), and Interaction to Next Paint (responsiveness). They are a ranking factor in Google search. We optimize all three.

Will optimization break our existing functionality?

No. We implement optimizations incrementally, test each change, and measure performance before and after. Code splitting, lazy loading, and image optimization do not change functionality; they change how and when resources are delivered to the browser.

How long does frontend performance optimization take?

A performance audit with prioritized recommendations takes 1 to 2 weeks. Implementing the optimizations takes 2 to 6 weeks depending on the number and complexity of issues. Setting up monitoring and performance budgets takes 1 week.
