Every second of delay costs you visitors, rankings and revenue. Site speed used to be an engineering concern; today it is one of the clearest growth levers you have. When a page loads instantly, everything downstream — SEO, ads, conversion — works harder.
What Core Web Vitals measure
- Largest Contentful Paint — how quickly the main content appears.
- Interaction to Next Paint — how responsive the page feels when tapped or clicked.
- Cumulative Layout Shift — how stable the layout is while it loads.
Where the seconds hide
Oversized images, render-blocking scripts, bloated plugins and slow hosting are the usual suspects. The fixes are rarely glamorous — compression, caching, lazy-loading, cleaner code — but the payoff is immediate and measurable.
Speed pays for itself
Faster pages rank better, hold attention longer and convert more of the traffic you already pay for. In other words, performance is not a cost centre — it is one of the cheapest ways to grow.
Speed as a growth channel — love this framing. Our bounce rate dropped ~18% after we fixed LCP.
Same experience. Fast sites convert better even before you touch anything in the funnel.
INP replacing FID caught a lot of teams off guard. Glad you covered the transition clearly.
Proper image sizing and lazy-loading did 80% of the work for us with 20% of the effort.
We shaved 1.2s off TTFB just by moving to a decent host and turning on object caching.
Could you do a deep dive on CLS? Layout shift from ads and web fonts is still our worst metric.
