Hair Salon Booking CWV

Core Web Vitals issues specific to hair salon websites — booking widget INP (Treatwell embed, Fresha, Vagaro, Phorest), Instagram embed CLS, before/after gallery image CLS, and hero photo LCP optimisation.

Definition

Hair salon CWV issues: (1) **Booking widget INP**: Treatwell embeddable booking widget, Fresha widget, Vagaro, Phorest, and Shortcuts booking system embeds all load JavaScript that introduces INP latency on the first slot selection click — lazy-load widgets behind a "Book Now" button click to defer script parsing; (2) **Instagram feed CLS**: Instagram embed widgets resize post-paint without a fixed container, causing significant CLS — replace with a static image grid or set explicit min-height on the embed container; (3) **Gallery CLS**: before/after photos without explicit width/height attributes cause layout shift as images load — every `<img>` in gallery sections needs dimension attributes; (4) **Hero photo LCP**: the hero before/after transformation image is typically the LCP element — serve in WebP, use `fetchpriority="high"`, preload with `<link rel="preload" as="image">`; (5) **Review badge CLS**: Google and Trustpilot badge embeds load asynchronously — set explicit height on badge containers before script execution.

Why it matters for SEO

Salon websites are among the most gallery-heavy and third-party-embed-heavy pages in local search — making them disproportionately prone to CLS and INP issues. Booking widget INP directly affects conversion at the point of intent.
