Calculate Your Performance ROI

Performance optimization isn't just about scores—it's about business impact. Here's how we calculate ROI.

SEO Value Increase

Google uses Core Web Vitals as ranking factors. Better performance = higher rankings.

Calculation Method
Based on keyword rankings and search volume
Optymizer.com Result
+$36,000 estimated SEO value

Conversion Rate Lift

Amazon found every 100ms delay costs 1% in sales. Faster sites convert better.

Calculation Method
Industry avg: 0.3% conversion increase per 100ms improvement
Optymizer.com Result
+18% conversion rate (estimated)

Bounce Rate Reduction

53% of mobile users abandon sites that take longer than 3 seconds to load.

Calculation Method
Reduced bounce rate = more engaged visitors
Optymizer.com Result
-28% bounce rate (estimated)

Infrastructure Savings

Smaller assets, better caching = reduced bandwidth and server costs.

Calculation Method
Based on bandwidth reduction and CDN efficiency
Optymizer.com Result
~$200/month savings potential

Total Estimated Annual Value

$50,000+

Based on Optymizer.com results: SEO value increase, conversion rate lift, bounce rate reduction, and infrastructure savings.

Investment: 3.5 hours × $150/hour = $525 | ROI: 9,423%

Frequently Asked Questions

How long does the performance optimization workflow take?

The complete workflow takes 2-4 hours on average, depending on site complexity. Simple sites (5-10 pages) take closer to 2 hours, while complex sites (50+ pages, heavy JavaScript) may take up to 4 hours. The Optymizer.com optimization was completed in 3.5 hours.

What agents are involved in this workflow?

Three specialized agents work together: performance-scout (assessment, prioritization, monitoring), asset-surgeon (implementation of optimizations), and qa-sentinel (testing and quality assurance). Each agent focuses on its area of expertise for maximum efficiency.

Will performance optimization break my site?

No. The qa-sentinel agent rigorously tests every change across devices, browsers, and network conditions before deployment. We verify that all functionality works correctly and that visual appearance remains consistent. Any issues are caught and fixed before going live.

How much improvement should I expect?

Results vary based on current performance, but typical improvements include: PageSpeed scores increasing 15-30 points, LCP reducing by 40-60%, and CLS improving by 70-90%. The key metric is business impact: better rankings, lower bounce rates, and higher conversion rates.

Is this a one-time optimization or ongoing?

Both. The initial workflow (Phases 1-4) delivers immediate improvements. Phase 5 sets up continuous monitoring to maintain performance over time. As you add content, features, or integrations, ongoing optimization ensures you maintain peak performance.

How do you calculate the $36K SEO value increase?

We use Google Search Console data to identify ranked keywords, their search volume, and average position. Tools like Ahrefs or SEMrush estimate the value of that traffic based on PPC costs for those keywords. Performance improvements that boost rankings increase this estimated value. For Optymizer.com, we saw keyword positions improve an average of 2-4 spots, translating to a $36K increase in estimated SEO value.
