Core Responsibilities: 1. Search Engine Architecture & Indexation (The Plumbing) * Enforce a strict, single-URL structure globally, managing server-side .htaccess or nginx.conf files to eliminate redirect chains and trailing-slash loops. Build and maintain dynamic XML sitemaps (page-sitemap.xml, product-sitemap.xml) that auto-update upon publishing. Optimize the robots.txt file to conserve crawl budget, blocking parameter URLs and internal search pages. Implement dynamic, self-referencing canonical tags across all pages to prevent duplicate content issues. 2. Core Web Vitals & Performance Engineering * Optimize Interaction to Next Paint (INP) by strictly deferring non-critical JavaScript until post-user interaction. Guarantee a Largest Contentful Paint (LCP) of under 2.5 seconds on mobile networks by implementing WebP/AVIF formats, preloading hero images, and enforcing strict lazy-loading below the fold. Eliminate Cumulative Layout Shift (CLS) by hardcoding dimensions for all media and resolving responsive CSS issues. Manage edge-caching and Content Delivery Network (CDN) rules for millisecond response times across India. 3. Advanced Structured Data (JSON-LD) * Write, deploy, and troubleshoot dynamic JSON-LD Schema markup across the site. Implement Product schema (detailing specs, brand, and ratings) and FAQ schema on all machinery pages to capture rich snippets on the search engine results page. Deploy VideoObject and Breadcrumb schema to establish clear site hierarchy and multimedia indexing. 4. UI/UX & Internal Link Automation * Develop a logical, flat "Silo" URL architecture for all industrial categories and products. Build automated internal linking modules (e.g., "Compatible Nozzles" dynamically linking to specific high-pressure pump pages). Ensure absolute mobile-first compliance: format technical specification tables to be horizontally scrollable on mobile, and ensure all tap targets are a minimum of 48x48 pixels. Required Skills & Qualifications: * Deep proficiency in front-end and server-side web development (HTML, CSS, JavaScript, PHP, and database management). Advanced expertise with Google Search Console (GSC), specifically diagnosing and fixing "Page with redirect," canonicalization, and indexation errors. Strong understanding of server configurations, caching mechanisms, and CDN deployments (e.g., Cloudflare). Ability to read, write, and validate complex JSON-LD Schema markup without relying solely on basic plugins. Performance Metrics (KPIs): * Speed: Google PageSpeed Insights Mobile Score > 90. Indexation: 100% of primary product pages indexed in GSC with zero "redirect" or "canonical" warnings. Code Quality: Zero errors in the Google Rich Results Test tool for all implemented schema.
