One Tool. Three Ways to Grow.
Whether you’re a freelancer, solopreneur, or small agency web developer, Serpence allows you to build websites that clients value without being an SEO expert.
Freelance Web Developers
Freelancers often work alone, managing tight budgets and timelines. Clients expect you to know everything—from coding to SEO—and delivering on those expectations can feel overwhelming, especially without specialized SEO knowledge.
Serpence provides a simple, intuitive tool that integrates SEO into your workflow, so you can confidently optimize every website you build. It offers actionable insights and clear explanations you can share with clients, making you look like an expert. Serpence also saves you time by automating SEO audits and providing step-by-step recommendations.
With Serpence, you can focus on coding while offering premium services that attract high-paying clients.

Solopreneurs
As a solopreneur, you’re a one-person business balancing website development, client acquisition, and delivering results. SEO feels like a black box—important, but hard to master without additional resources.
Serpence simplifies technical SEO, breaking it down into manageable steps that fit into your existing workflow. It automatically identifies SEO issues and offers clear, actionable solutions, helping you deliver websites that rank better. Empowers you to upsell SEO services without needing to hire or learn advanced techniques.
Serpence helps you work smarter, not harder, so you can grow your business without sacrificing quality or time.

Small Agencies
Small agencies are often stretched thin, trying to scale services while meeting diverse client demands. Delivering high-quality, SEO-optimized websites can be a bottleneck, especially without an in-house SEO team.
Serpence equips your team with the tools to offer technical SEO services, no matter their expertise level. It streamlines SEO reporting, making it easy to communicate the value of your work to clients. Frees up your team’s time by automating complex SEO tasks, allowing you to focus on growing your client base.
Serpence enables your agency to stand out in a competitive market by adding SEO as a seamless part of your offering.
