Frequently Asked Questions
How accurate is this calculator?
This calculator is based on well-documented research from Google and Akamai showing that each additional second of page load time reduces conversions by approximately 7%. Actual results depend on your industry, audience, and other factors, but it provides a reliable directional estimate.
How fast should my website be?
Google recommends pages load in under 3 seconds, but for best results, aim for under 2 seconds. Studies show that 53% of mobile visitors leave a site that takes longer than 3 seconds to load.
What is the most common speed bottleneck?
Unoptimized images account for over 50% of total page weight on most websites. Other common bottlenecks include render-blocking JavaScript, too many HTTP requests, lack of browser caching, and unminified CSS/JS files.
Is website speed really a ranking factor?
Yes. Core Web Vitals have been a direct Google ranking factor since 2021. Page speed affects both your search rankings and user experience, making it one of the highest-impact improvements you can make.
What does the 7% conversion improvement per second mean?
Industry research shows that for every 1-second improvement in page load time, conversion rates improve by an average of 7%. This means a site loading in 2 seconds instead of 5 seconds could see roughly a 21% improvement in conversions.
