FAQ
Which platforms do you optimize for speed?
I optimize Squarespace, Shopify, Wix, and WordPress websites. Each platform has its own performance limitations and I know exactly how to work within them to get the best possible speed improvements without breaking your site's functionality or appearance.
How much faster will my website be after optimization?
Results vary depending on your current setup but most sites see significant improvement in Google PageSpeed scores and load times after optimization. I provide a full before and after comparison so you can see exactly what changed and by how much.
Will speed optimization affect my website's appearance?
No. All optimizations are done under the hood — your site's visual appearance, layout, and content remain completely intact. I test everything thoroughly across desktop and mobile before delivering to make sure nothing is visually disrupted.
What is Core Web Vitals and why does it matter?
Core Web Vitals are Google's official set of performance metrics that directly influence your search rankings. They measure loading speed, visual stability, and responsiveness. Poor scores can push your site down in search results — good scores give you a clear ranking advantage.
Do I need to give you access to my website?
For the audit — just your URL is enough. For the fix and full optimization packages, I will need editor or admin access to your platform. I handle everything securely and will walk you through exactly what access is needed before we begin.
