Job Title: Technical SEO & Page Speed Optimization Specialist for HTML Site (SiteGround Hosting)

Job Title: Technical SEO & Page Speed Optimization Specialist for HTML Site (SiteGround Hosting) I am looking for an experienced Web Performance Optimization (WPO) and Technical SEO specialist to fix server delays, resolve 404 errors, and optimize my website's Core Web Vitals for mobile. Current Setup: Platform: Pure HTML/CSS/JS (This is NOT a WordPress site). Hosting Provider: SiteGround. Current Issues to Fix: High TTFB / Server Latency: Google PageSpeed Insights shows a Time to First Byte (TTFB) of 2.0 seconds on mobile. I need this optimized down to under 0.5 seconds using SiteGround's server capabilities (NGINX Direct Delivery, SiteGround CDN, etc.) and code-level optimization. Core Web Vitals: The site is currently failing the mobile Core Web Vitals assessment due to a slow Largest Contentful Paint (LCP of 3.6s). 404 Crawl Errors: Google Search Console is reporting roughly 47 "Not Found (404)" errors. Many of these look like broken pagination links (e.g., URLs containing ?page=6). Because this is a static HTML site, these broken internal links need to be cleaned up manually within the source files or handled via proper redirects. Required Skills: Expert knowledge of SiteGround hosting, Site Tools, and server-level caching. Strong proficiency in raw HTML, CSS, and JavaScript (no reliance on WordPress plugins). Proven track record of improving Google PageSpeed Insights / Lighthouse scores (specifically targeting mobile TTFB and LCP). Deep understanding of Google Search Console and fixing 404 crawl errors. To Apply: Please start your proposal with the word "FAST" so I know you have read the full description. Briefly explain your experience with optimizing pure HTML sites on SiteGround and how you plan to tackle the 2-second TTFB delay.
