Professional Profile
Colin Janoshegyi, also known as Colin John, is a digital marketer and SEO specialist with a background in Business Administration. His work sits at the intersection of search engine optimisation, content marketing, digital strategy, consumer behaviour, and website development.
He works primarily on helping businesses become easier to find online and turning that visibility into something useful for the business. His approach combines technical implementation with content, search intent, user behaviour, and a broader understanding of how people actually discover and evaluate information.
Alongside client and professional marketing work, Colin builds and experiments with websites and digital tools. He is particularly interested in how search engines understand websites, how AI systems retrieve and interpret information, and what happens when people try to manipulate those systems.
Areas of Expertise
- Search Engine Optimisation (SEO), including technical SEO, on-page optimisation, search visibility, and SEO audits
- Content Marketing Strategy, including keyword research, search intent, content planning, and performance optimisation
- Technical SEO and website optimisation, connecting marketing strategy with practical implementation
- AI search, Generative Engine Optimisation (GEO), Answer Engine Optimisation (AEO), and entity-based search
- Front-end web development using HTML, CSS, and JavaScript, with an emphasis on SEO-friendly implementation
- Digital marketing and brand growth, particularly for SMEs, hospitality, food-service, and growing businesses
- Analytics and performance tracking using tools such as Google Analytics, Google Search Console, and SEO platforms
- Web security topics that overlap with search, including user-agent cloaking, SEO spam, and parasite SEO
Current Focus
Colin's current interests increasingly sit around the changing relationship between search engines, websites, and AI systems. He is interested not only in ranking pages, but in how information is interpreted, surfaced, trusted, and sometimes manipulated.
- Improving search visibility through technically sound SEO and useful content
- Understanding AI search and how entities, content, and websites are represented by AI systems
- Building websites and tools that combine marketing, development, and practical problem-solving
- Investigating search manipulation, user-agent cloaking, SEO spam, and parasite SEO
- Exploring how businesses can build sustainable organic visibility instead of relying on short-term tactics
Selected Projects
Cloaker Checker
Cloaker Checker is a web-based tool Colin built to investigate user-agent cloaking. It checks whether a website presents substantially different content to search-engine crawlers compared with ordinary visitors, helping identify potential SEO manipulation and related security concerns.

Notes & Thoughts is the writing section of Colin's website. Most of the writing explores SEO, marketing, technology, search, and digital culture. One essay, The Universe Owes You Nothing (And That's Wonderful), takes a more personal direction and explores philosophy, meaning, loss, absurdism, and the human condition.

Point of View
Colin believes the internet works best when businesses focus on being genuinely useful. Search engines and platforms change constantly, but understanding customers, creating useful information, and building a solid digital foundation tends to survive those changes.
His work is less about chasing an algorithm and more about understanding why people search, what they need, and how a business can become the useful answer.
