SEO Specialist & SEO Content Writer · Founder of ZHBULBUL · SEO Specialist at Pixwelz
Md. Zahidul Hassan Bulbul is an SEO specialist and SEO content writer who builds topical authority through semantic SEO. He runs ZHBULBUL, an independent SEO and content consultancy working with clients in the United States, the United Kingdom and Bangladesh, and works as SEO Specialist and Content Writer at Pixwelz, a web design and development studio in London.
About Md. Zahidul Hassan Bulbul
Md. Zahidul Hassan Bulbul plans and writes content that search engines can parse and readers can act on. His method is semantic SEO: map a topic completely, organise it around search intent and entities rather than isolated keywords, then write pages that answer real questions in plain language. That approach has produced 250 percent organic traffic growth on client sites.
He came to search from commercial work rather than from a marketing degree. Ten years at Telenor ASA (Grameenphone) in territory management, compliance and channel expansion were followed by business development in IT at Infinity Technology Solutions, and corporate account management at 1000Fix Services and Thakral Information Systems. That background still shapes how he writes: a page is judged on whether it moves a business forward, not on word count.
He moved into search full time in November 2022 as an SEO specialist at Myfriendico, serving United States clients across SEO, website optimisation and digital marketing. In July 2024 he founded ZHBULBUL as an independent consultancy. Since February 2026 he has also worked as SEO Specialist and Content Writer at Pixwelz, where he builds topical maps and content clusters for client websites.
He holds an MBA and a B.Sc. in Computer Science and Engineering from the University of Asia Pacific, and is certified by Semrush and HubSpot. He works remotely from Bangladesh with regular overlap into United States and United Kingdom time zones.
He believes good content starts with understanding the reader, organising information around topics instead of keywords, and earning trust through clarity, accuracy and demonstrable expertise.
