THE PERSON BEHIND THE WORK
Santanu Rakshit is the Founder and CEO of Search4online, where he works at the intersection of SEO, digital authority, link building, Digital PR and the rapidly evolving world of AI-powered search.
His journey in search marketing began in 2018, with a strong focus on one of SEO's most challenging disciplines: building genuine authority beyond a brand's own website.
Over the years, Santanu has worked extensively with publisher outreach, strategic link acquisition, content-led authority building and agency partnerships. That hands-on experience eventually helped shape Search4online into an international SEO and authority-building operation supporting businesses and agencies across competitive markets.
Today, his focus is expanding beyond traditional search rankings. As platforms such as ChatGPT, Google AI Overviews and Perplexity change the way people discover information, Santanu is increasingly focused on how brand authority, citations, publisher mentions, structured information and topical relevance influence visibility across both search engines and AI systems.
WHERE STRATEGY MEETS PRACTICE
Authority, relationships and the next chapter of search.
Building authority outside a brand's own website through relevant links, mentions, publisher relationships and digital trust signals.
Developing link-acquisition strategies around relevance, genuine publications, traffic, authority and long-term value rather than backlinks alone.
Creating opportunities for brands to earn meaningful third-party mentions and editorial authority.
Exploring how businesses become discoverable and cited across AI-powered search and answer engines.
Connecting traditional SEO fundamentals with entity signals, authoritative citations, structured information and the emerging generative-search ecosystem.
Developing relationships with publishers and media websites across international markets.
Supporting SEO and digital agencies that need scalable authority-building and link-acquisition fulfilment.
Building systems and workflows that make outreach, publisher discovery and campaign management more scalable.
THE WORK, IN PRACTICE
From hands-on outreach to leading an authority-building agency.
2018 — Present
Santanu co-founded Search4online in 2018 with the goal of building a more transparent and quality-focused approach to link building and digital authority.
His role has evolved from hands-on SEO and publisher outreach into leading strategy across link acquisition, Digital PR, AI-search visibility, agency partnerships and scalable outreach operations.
Today, he oversees the broader direction of Search4online while continuing to work closely with evolving search strategies, publisher ecosystems and AI-driven discovery.
SANTANU’S APPROACH
Search visibility is becoming broader than rankings alone.
A strong brand needs credible third-party signals, not simply content published on its own website.
A contextually relevant publisher can be more strategically valuable than pursuing metrics without considering audience or topic.
Strong link building depends heavily on genuine relationships with publishers, editors, agencies and other participants in the digital ecosystem.
As search evolves, brands need to consider how machines understand their identity, authority and expertise — not simply where individual webpages rank.

AN INTERNATIONAL PERSPECTIVE
Santanu actively follows developments across SEO, AI search, digital publishing and authority building.

The business grew from their focus on solving a recurring problem in link building: finding relevant, credible publishing opportunities while maintaining sensible pricing, quality control and reliable fulfilment.
Since then, Search4online has evolved beyond straightforward link placement into a broader SEO, Digital PR and authority-building operation.
As the search ecosystem changes, the company is also developing its approach around AI-powered discovery and Generative Engine Optimisation.
