ONmetrics

Based in London, Ontario, ONmetrics is a digital marketing consultancy operated by Dave De Vries, serving businesses across London and Southwestern Ontario, including areas such as St. Thomas, Woodstock, Stratford, Strathroy, Tillsonburg, Ingersoll, Exeter, Aylmer, and Dorchester. The consultancy works with clients in sectors such as restaurants, dentistry, law, contracting, and real estate. Founded in 2014, the business is structured as a single-operator model, meaning clients work directly with De Vries rather than being passed between junior staff across a larger team. Services span SEO, PPC (Google Ads), web design, data and attribution, conversion rate optimization, email marketing, content marketing, reputation management, and AI services. Technical work includes SEO audits, Google Ads account management, conversion-focused web design, and data attribution intended to connect marketing activity to revenue outcomes. The agency offers a free marketing audit, delivered within 48 hours, covering SEO health, ad performance, website conversion metrics, and attribution gaps; this audit is personally reviewed by De Vries. Over the course of his career since 2014, he has managed more than $50 million in advertising spend and completed over 200 marketing audits for businesses in the region. The stated approach centers on treating SEO, PPC, web design, and data visualization as interconnected components of a single growth process rather than separate, siloed services, with an emphasis on measurability and accountability for marketing spend.
