As an SEO Strategist, I conducted comprehensive SEO audits to identify technical issues, on-page opportunities, and performance gaps across client websites. I developed keyword maps aligned with user intent and business goals, and implemented optimization strategies that boosted visibility and search performance. I improved site speed and performance using tools like PageSpeed Insights, GTMetrix, and Core Web Vitals. I submitted XML sitemaps to Google and Bing Webmaster Tools and resolved indexing issues via Search Console. I also worked on Local SEO initiatives by refining and optimizing business profiles using Google My Business to improve map visibility and local search results. In addition, I led link-building initiatives and monitored off-page SEO effectiveness. Collaborating closely with developers, designers, and content writers, I ensured SEO best practices were integrated across site structures and campaigns. I regularly provided clients with performance insights and recommendations through reports created in Looker Studio and Google Analytics 4.

At Zovio, I led SEO strategy and landing page development across multiple higher education brands. I conducted comprehensive SEO audits and optimized site structure and page performance using HTML, JavaScript, and CMS platforms. I developed tracking URLs and measured campaign effectiveness through Google Analytics. I also managed A/B testing for key landing pages, resulting in a 15% increase in user engagement and sign-ups. One of my standout accomplishments was the creation of SEO-optimized landing pages that generated over 50,000 visits within the first week.

As the Founder and Digital Marketing Consultant at DiMarC Designs, I provide tailored digital strategy and website solutions to small business clients in the food, hospitality, logistics, and tech industries. My work includes building SEO-optimized websites using WordPress and HTML/CSS, conducting in-depth keyword research and competitive analysis, and performing technical audits to shape comprehensive SEO strategies. I guide clients on content architecture and keyword integration to strengthen both blog and website performance. I also develop niche-specific link-building strategies to improve domain authority and visibility. In addition, I support local SEO by refining business profiles through platforms like Google Business. I communicate performance trends and evolving priorities through clear, data-driven reporting and strategy reviews.
