Jericho De Guzman — SEO and digital marketing specialist based in Manila, Philippines

"Good marketing isn't about doing everything — it's about doing the right things, consistently, and proving it with data."

Hi, I'm Jericho. I've been freelancing in SEO and digital marketing since 2018 — over 7 years spent helping more than 100 businesses worldwide grow their visibility and revenue. Along the way, I formalized that hands-on experience through certifications in SEO and web development from the Department of Information and Communications Technology (DICT), Philippines, plus credentials from Google, EC-Council, CompTIA, and the University of Illinois Urbana-Champaign. Today I specialize in on-page, off-page, and technical SEO — alongside web development (WordPress & Shopify), social media management, and AI-powered digital marketing strategy. My grounding in core SEO concepts — LSI, crawler behavior, search engine spiders, link building, and call-to-action optimization — gives me a full-stack view of what actually moves a business up the rankings and into more customers' hands. I'm a devoted freelancer, and I invest constantly in research and continued learning to stay ahead in a fast-moving field. If you're looking for someone to grow your business online, I'd love to talk.
