About Me

A results-driven
digital innovator.

I'm Nil Ratan Karmakar — a Digital Marketer, SEO specialist, and founder with a relentless passion for turning data into sustainable business growth.

With over 8 years of hands-on experience, I've built and scaled campaigns across e-commerce, SaaS, real estate, and education. I bring a founder's mindset to every engagement: move fast, measure everything, and optimize relentlessly.

Outside of client work, I invest in early-stage startups, share insights on digital marketing, and stay at the cutting edge of search and paid media innovation. I believe the best marketers are part analyst, part creative, and fully accountable to results.

Questions

Frequently Asked

Google Ads drives traffic from day one. For meaningful ROAS optimization, expect 2–4 weeks of data collection. Significant performance improvements typically appear within 30–60 days as bidding, audiences, and creative are refined based on real data.
SEO is a long-term investment. Technical fixes show improvements in 4–8 weeks. Content and link-building strategies typically drive meaningful organic traffic growth within 3–6 months, with compounding results thereafter. I set realistic expectations from day one.
Absolutely — I work with clients worldwide on a fully remote basis. I've managed campaigns for businesses in the US, UK, Australia, UAE, and across South Asia. Time zones are not a barrier; I adapt to my clients' schedules.
For Google Ads, I recommend a minimum monthly budget of $500–$1,000 USD to gather meaningful data and achieve results. Below this threshold, campaigns don't accumulate enough data to optimize effectively. I'm happy to advise on the right budget for your specific goals and market.
Yes! I offer one-time Google Ads audits, SEO audits, and strategy sessions. These are ideal if you have an in-house team but want an expert second opinion or a detailed action plan. Reach out via the contact form to discuss your needs and I'll provide a custom quote.
I provide weekly performance updates and detailed monthly reports through Looker Studio dashboards with 24/7 client access. Growth and Enterprise clients get access to a shared Slack channel for quick questions and real-time updates. Full transparency — always.
