Core Web Vitals Checklist for B2B Websites

Google uses Core Web Vitals as a ranking signal. B2B sites with heavy hero animations and third-party scripts often fail INP—losing traffic before sales ever sees a lead.

This guide is written for owners, IT heads, and operations leaders evaluating software investments in India— with practical cost ranges, build-vs-buy frameworks, and implementation checklists you can use in vendor meetings.

LCP under 2.5s

Preload hero fonts and LCP images. Avoid lazy-loading above-the-fold media.

• Use next/image with priority
• Limit custom font weights
• Self-host critical assets

INP under 200ms

Defer non-critical JS. Split Framer Motion to below-fold sections only.

What high-converting B2B websites include in 2026

Buyers research on Google and AI assistants before contacting sales. Your site must answer commercial-intent queries with specificity—pricing ranges, timelines, industry case studies, and interactive estimators.

Core Web Vitals in the green zone is table stakes; differentiation comes from trust architecture and service-specific landing depth.

• Industry-specific service pages (not one generic Services page)
• Case studies with metrics—not only logos
• Interactive cost/ROI calculators
• FAQ schema on commercial pages
• Book consultation with context passed to CRM

Next.js architecture for SEO and conversion

Static generation for content hubs, structured metadata API on every route, and minimal client JS on above-the-fold content. Forms should post to CRM with UTM and service context preserved.

Key takeaways for decision-makers

Start with measurable pain—inventory accuracy, lead response time, or month-end close duration. Software ROI should be expressed in hours saved and error reduction, not features shipped.

Sequence implementation in phases with weekly demos. Avoid big-bang go-lives across all plants or departments simultaneously.

• Quantify baseline metrics before project kickoff
• Run paid discovery before fixed-price build contracts
• Demand IP ownership and exportable data
• Plan hypercare for 4–6 weeks post go-live
