Two-thirds of organic search is mobile. Optimize for mobile first — desktop is now the secondary surface.
LCP under 2.5s is the single most important speed metric. Optimize hero images first.
Move to AVIF/WebP for hero images. The 40-60% byte savings translate directly to faster LCP and lower bounce.
INP replaced FID in 2024 — under 200ms is the new bar. Defer heavy JavaScript and split bundles.
Mobile conversion friction is real. Audit your checkout/forms on a mid-tier Android phone, not your latest iPhone.
Roughly 64% of all organic search traffic comes from mobile devices, with desktop at about 31% and tablets making up the remaining ~5%. The mobile share is even higher in emerging markets and for B2C queries.
LCP under 2.5 seconds, INP under 200ms, and CLS under 0.1 — these are Google's three Core Web Vitals thresholds. Hitting all three is the bar to clear; pages that miss can still rank but lose ~10-25% of potential conversions.
Yes — and it's now the universal default at Google. There's no separate desktop index. The mobile version of your page is what Google sees, evaluates, and ranks.
Five biggest levers, in order: (1) compress and convert hero images to AVIF/WebP, (2) preload the LCP image, (3) defer non-critical JS and CSS, (4) lazy-load below-the-fold images, (5) audit and remove third-party scripts that aren't business-critical.
Yes — directly and measurably. 53% of users abandon mobile pages that take more than 3 seconds to load, and pages passing all three Core Web Vitals show 24% lower abandonment on average. Speed is no longer a ranking factor only — it's a conversion factor.
