Common Speed Questions
What is a good website speed score?
Google PageSpeed Insights scores from 0–100. A score of 90–100 is Excellent. Below 50 is Poor and means you are actively losing mobile visitors before your page even loads.
Why is my website slow on mobile?
Common causes include bloated WordPress plugins, unoptimized images, slow shared hosting, and large JavaScript bundles. Lumbre Design eliminates all of these with a serverless Next.js architecture.
How can I improve my Google PageSpeed score?
Compress images to WebP, remove unused scripts, enable a CDN, and switch from WordPress to a modern framework like Next.js. Or simply hire Lumbre Design — we guarantee a 95+ mobile score on every project.
Does website speed affect my Google ranking?
Absolutely. Google officially uses Core Web Vitals (which include LCP and FCP) as direct ranking signals in Search. A slow site ranks lower than a fast competitor, even if your content is better.
