I’m Marcus Vale. With eight years focused on the technical side of e-commerce SEO, I’ve tackled large-scale migrations, international hreflang setups, and JavaScript rendering issues that stifle crawling. I’m certified in DeepCrawl and Google Tag Manager, and I’ve led teams through three enterprise-level platform changes without traffic loss. I also run quarterly code audits for performance and accessibility, ensuring sites load fast and comply with WCAG standards.
