Technical SEO services
Technical SEO services, engineered for dev & marketing teams.
Six engineering-led disciplines for ecommerce platforms and content publishers. Each one starts from data, ends inside your release process, and is written in a language both your developers and your marketers understand.
The disciplines
Six services, one connected system.
Engage one service on its own or combine them. Most clients start with a technical SEO audit, then move into the specialist work the audit surfaces.

Why engineering-led
Where engineering meets search optimization.
Most developers don’t care about SEO, and most SEOs don’t understand code. That gap is where organic growth quietly stalls.
Technical SEO services usually arrive as recommendations: a spreadsheet of issues, a slide deck of best practices. Development teams are then left to interpret them, prioritise them against product work and guess at the implementation. Most of it never ships.
Every SDN service is delivered as engineering work: root causes traced to templates and components, fixes specified with acceptance criteria, and automated checks that keep them in place. Marketing gets measurable outcomes; development gets work it can actually pick up. Read more about our technical SEO methodology.

FAQ
Questions about our technical SEO services.
Not sure which service fits? Tell us the problem and we’ll recommend the smallest engagement that solves it.
What are technical SEO services?
Technical SEO services improve how search engines crawl, render, index and understand a website. They cover audits, site architecture, JavaScript rendering, page performance, structured data and migrations — the engineering foundations that content and links depend on.
Which service should we start with?
Most teams start with a technical SEO audit, because it ranks every issue by impact and tells you which specialist work is worth doing. If you’re about to migrate or have a known rendering or performance problem, you can start there directly.
Do you work with agencies and in-house teams?
Yes. We regularly work alongside in-house developers, product teams and marketing or content agencies, slotting into your tools and processes rather than adding new ones.
How are services priced?
Each engagement is quoted as a fixed scope based on site size, platform complexity and deliverables. Retainers are monthly and can be cancelled at any time.
Do you offer content or link building?
No — SDN is technical only. We’re happy to brief and collaborate with your content or digital PR partners so their work lands on a technically sound site.
