Assertive Media

History and Founding

Assertive Media was founded in 2007 by Daniel Foley Carter, who had previously worked for large SEO agencies in London before launching his own venture. The company’s early focus was on delivering enterprise-level SEO services, and over time it expanded into paid marketing, content, and conversion optimisation. The founding team’s experience dates back to before Google’s dominance, giving the agency a long-standing perspective on search engine evolution.

Services and Specialisation

Assertive Media describes itself as a “performance digital marketing agency” that is “data driven & ROI focused.” Its core services include Search Engine Optimisation (auditing, strategy, technical SEO, content optimisation, and link building), AI SEO & LLM Optimisation (GEO/AEO) for generative search, Pay-Per-Click Advertising (paid search, social, remarketing, and video campaigns), Digital PR & Conversion Rate Optimisation (integrated campaigns to build brand authority and improve on-site conversion), and Enterprise SEO Solutions (bespoke retainer, contract, and ad-hoc consulting). The agency has developed deep expertise in highly regulated niches, including gambling, casino & iGaming, affiliate marketing, financial services, healthcare, pharmaceutical, cyber security & defence, and government & local authority.

Technology and Proprietary Tools

Assertive Media has built its own SEO tool called SEO Stack (seo-stack.io), which integrates with Google Search Console and uses AI annotations, SEO testing, and query counting to provide data-backed recommendations. The agency emphasises a “big data approach” to SEO, leveraging first-party data to inform technical, content, and link acquisition decisions.

Clients and Market Position

The agency’s client portfolio includes globally recognised brands such as Lenovo, Allianz, BNP Paribas, Virgin, Easy Group, SAGE, and Supreme Imports. Assertive Media reports strong client retention over 1-, 3-, and 5-year periods, and it actively invests in internal training and skill development to maintain high-quality delivery. The company is headquartered in London and operates as a public company (as listed on LinkedIn), though it remains privately held.

Leadership and Team

The company was founded by Daniel Foley Carter, who serves as Founder and Senior SEO. With over 24 years of SEO experience dating back to 1998/1999, he provides internal training and strategic direction. No other C-level executives (CEO, CTO, CCO, COO, CFO) were explicitly identified in publicly available sources. The team size is estimated at 11–50 employees, with roles spanning account management, content, and technical SEO.

Recent Developments

Assertive Media continues to expand its international presence, with a stated mission to double operations over the next 2–3 years and strengthen positions in US, CA, AU, and UK markets. The agency also supports clients with paid marketing, social media, and conversion optimisation, positioning itself as a full-service digital partner for complex, compliance-heavy industries.
