Questions

Frequently Asked Questions

Everything Denver businesses need to know about our speed optimization services.

On average, our Denver clients see a 3–5x improvement in page load speed. Most sites go from a Lighthouse score in the 20–50 range to 90+ after optimization. The exact improvement depends on your current setup, but we guarantee measurable results or your money back.
Yes. We optimize WordPress, Shopify, Squarespace, Wix, and custom-built sites (React, Next.js, static HTML, etc.). Our team has deep experience with each platform's specific performance bottlenecks and optimization techniques.
Most optimizations are completed within 3–10 business days depending on which package you choose. Speed Boost is 3–5 days, Performance Pro is 5–7 days, and Enterprise Speed is 7–10 days. Complex enterprise sites may take slightly longer, which we will communicate upfront.
No. We test thoroughly before and after every change. We work on a staging environment first, run automated regression tests, and only push to production after full QA. We also keep complete backups so we can roll back instantly if needed.
Yes. If we do not improve your Lighthouse score by at least 30 points, you get a full refund. We stand behind our work because we know our optimization process delivers results consistently for Denver businesses and beyond.
