11 Internet is the professional practice of Jan-Willem Bobbink, a Dutch SEO consultant who has operated at the technical end of the search industry since 1997. Based in The Hague, the consultancy functions as an elite tactical resource for enterprise-scale organizations that require more than basic keyword research. It sits at a specific intersection of data engineering and marketing, specializing in the deployment of programmatic content and large-scale technical audits.

The mechanics of enterprise search

Bobbink’s work is characterized by a reliance on data rather than traditional copywriting. This is most evident in the development of the Listicle Wizard, a tool designed for data-driven listicle generation. This product reflects a broader shift in the SEO industry away from manually authored posts toward structured, automated content that can be scaled across thousands of pages. By using LLMs and structured datasets, 11 Internet enables clients to occupy large swaths of search results without the overhead of a massive content team. This approach is particularly effective for aggregators, marketplaces, and travel sites where content needs to be both vast and accurate.

A background in affiliate and technical engineering

The foundation of 11 Internet is Bobbink’s background as a web developer and affiliate marketer. This technical literacy is what differentiates the firm from standard creative agencies. In the late 2000s, when many SEOs were focused on link building, 11 Internet was already moving toward technical infrastructure and server-side optimization. This early focus on the "how" of the web allowed the consultancy to secure a client list that reads like a index of the Dutch digital economy. Current and past collaborations include Randstad, Vice.com, GetYourGuide, Messagebird, and Adevinta, the parent company of Marktplaats.nl.

Strategic independence

Operating as a freelance entity allows 11 Internet to remain agile. The consultancy charges a premium hourly rate, starting at €125, which reflects its position as a high-end specialist. This model is common among top-tier technical SEOs who prefer to maintain direct control over strategy rather than delegating work to junior account managers. The firm is also deeply integrated into the SEO community through Bobbink’s blog, NotProvided.eu, where he shares insights on the technical shifts in search algorithms. This constant public output serves as both a marketing tool and a commitment to maintaining a lead in a rapidly changing field.

Positioning for the generative era

As search engines transition into AI-powered answering engines, 11 Internet is focusing on how brands can remain visible in an "Agentic" search world. This involves moving beyond simple tags and toward structured data that AI models can consume. The firm is essentially helping companies prepare their digital assets for a future where the primary consumer of a website might be an LLM or an AI agent rather than a human browsing a desktop screen. This forward-looking strategy ensures that the consultancy remains relevant even as traditional search behavior evolves.
