We work with companies across multiple industries because we believe real marketing expertise is not about being locked into a single niche, but about the ability to research, understand, and win in any market. Our teams follow a research-driven playbook: deep industry and competitor analysis, understanding regulations and audience behavior, and rapid testing to find what truly converts. This approach has already delivered proven results in B2B and SaaS, crypto and Web3, fintech and financial services, IT and software, gaming and iGaming, e-commerce, real estate, healthcare, forex, AI and more, with new verticals constantly added to our portfolio.

The Pioneers of Pay for Performance SEO. At GreenBanana SEO saw an opportunity amidst the category of search engine optimization (SEO) providers. There was a strong current of overused buzzwords like ‘keyword clusters’, ‘behavior diagnostics’, and ‘search influencers’ floating around. Waves of flashy sales presentations made SEO look like black magic. Prices to clients were on the rise while performance and accountability were shrinking.

That’s when GreenBanana was born. We are a scrappy, hard-working group of people passionate about connecting prospects to your business every day. We are laser-focused on performance. We strive to build trustworthy relationships with each and every client. We keep it simple by doing the work and clearly communicating our process to clients. Accountability and results are our ‘buzzwords.’ And it’s not just lip service. We speak it, but we also create a structure for our clients so they can believe it.
