Company snapshot
Roadmap is a free, open source platform that helps developers figure out what to learn next through structured, interactive learning paths for every major technology stack. Built by Kamran Ahmed, the second most starred developer on GitHub globally, the site had strong brand recognition, a 300K+ star GitHub repo, and a growing organic presence. But they wanted to move faster. The goal was to aggressively scale topical authority across developer education, rank for high-volume keywords that mattered to developers at career decision points, and turn roadmap into the definitive organic destination for developer learning.

The challenge
Roadmap had a content strategy in place and a clear vision for where they wanted to go. They knew the hub and spoke model was the right approach and which technology tracks to prioritize. But executing at the speed and scale they needed required a partner who had already done it for developer tools, understood how developers search, and could produce technically accurate content without months of onboarding. Finding writers who could cover system design, backend development, AI engineering, and game development at the depth developers expected was the bottleneck.
We knew what we wanted to build but needed an SEO partner who truly understood developers. Hackmamba came in and got it immediately, - Kamran Ahmed, Founder, Roadmap
We have a pool of 3,000+ technical writers with engineering and computer science backgrounds, paired with SEO experts who had already executed this exact strategy for developer tool companies. That is why they came to us.
Our approach
1. Mapping the topic cluster architecture
Roadmap has two types of hub pages. Role-based roadmaps covering career paths like Frontend, Backend, DevOps, AI Engineer, and Game Developer. Skill-based roadmaps covering specific technologies like React, TypeScript, Node.js, System Design, and Kubernetes.
2. Content brief and technical writing
Every spoke page started with a brief. We ran keyword research, identified the search intent behind each concept, and built a content brief that told the writer exactly what the page needed to accomplish. The brief included the target keyword, audience, outline, and the product angle tied to a signup. From brief to published page, our process takes 10 to 14 days. With a pool of 3,000+ technical writers with engineering backgrounds, we matched each technology track to writers who had actually worked in that stack. A page about system design was not written by a generalist. It was written by someone who understood distributed systems. You can read more about our full technical writing process here.
3. How the Hub was built
Take roadmap.sh/frontend as the example, targeting "frontend development" at 58K monthly searches. The page answers every question a developer has at a career decision point: what frontend development is, which languages to learn, what frameworks to pick, and what the full skill set looks like. It has an interactive visual roadmap walking developers from Internet basics through HTML, CSS, JavaScript, frameworks, testing, and deployment, with FAQs covering career questions, interview prep, and salary.
4. How the Spokes were built
From the hub, every concept branches into its own spoke page. roadmap.sh/frontend/languages covers frontend programming languages. roadmap.sh/frontend/frameworks covers frontend frameworks. roadmap.sh/frontend/developer-skills covers the full skill set. Each spoke targets a specific long-tail query, answers it completely, and links back to the hub. We replicated this across every role-based and skill-based track on the platform. As we cover in our SEO guide for developer tools, this is exactly how topical authority is built at scale.
5. Organic backlink growth
One of the strongest signals of this engagement was the backlink growth that happened without any outreach. Because the hub and spoke pages were built to be the most comprehensive resource on each topic, other developers and technical writers naturally linked to them. Tutorial writers used the hub pages as a reference point for their readers. Job description pages cited roadmap pages when listing required skills. Developers linked to spoke pages in blog posts when explaining a concept. This is what drove referring domains from 2,475 to 6,256 in 24 months, with 259 links coming from domains with a DR of 90 and above and 2,047 from domains between DR 70 and 89, all earned, none flagged as spam.
