Google Ranks Fast Sites Higher
Core Web Vitals = Google's speed metrics. Pass them, get a ranking boost. Fail them, rankings suffer. That e-commerce site went from failing all three to passing all three. Rankings climbed for every keyword they tracked. Speed isn't optional for SEO anymore.
Slow Sites = High Bounce Rates = Lower Rankings
Takes 6 seconds to load? 70% of people bounce. Google sees that and thinks "this site sucks." Rankings drop. Fast load = people stay = Google thinks "this site's good" = rankings improve. Bounce rate is a ranking signal.
Images Are Usually the Problem
That site had 5MB product images loading on every page. Compressed them to 150KB each. Instant speed improvement. Use tools like TinyPNG before uploading. Convert to WebP format. Lazy load images below the fold. Simple fixes, huge impact.
Mobile Speed Matters Even More
Mobile users on 4G don't wait. 3 seconds = they're gone. Google uses mobile speed for rankings. That site was 9 seconds on mobile before optimization, 2.1 seconds after. Mobile rankings jumped even faster than desktop.
At Malmquist Consulting, we build inherently fast sites: optimized images, clean code, quality hosting, passes Core Web Vitals out of the box. Sites that rank higher because they load faster. Speed equals SEO.
