IT Engineering Consultant · Technical SEO
Technical SEO consulting, where engineering meets search optimization.
Most developers don’t care about SEO. Most SEOs don’t understand code. Strategy Digital Node bridges that gap — turning crawl, render and performance data into specifications your developers can ship and your marketers can measure.

The gap we close
Two disciplines that rarely share a language.
Organic growth stalls in the space between the people who build the website and the people who are measured on its traffic. That space is where we work.
Developers ship. SEO is an afterthought.
Client-side rendering hides content from crawlers
Faceted navigation explodes into millions of URLs
Performance is a lab score, not a field metric
SDN
SEO recommends. Nothing gets merged.
Audits arrive as 80-page PDFs nobody reads
Tickets have no acceptance criteria
No way to test SEO changes before release
Our position
We write strategy as specification: URL rules, template contracts, schema models and CI checks — a diff your developers can merge, and a metric your marketers can defend.

SHIPPED IN YOUR REPO
Who we work with
Built for platforms where search is revenue.
Ecommerce platforms
Large catalogues fail quietly: millions of filter URLs, variants competing with each other, out-of-stock pages bleeding equity. We fix the architecture behind it.
Typical findings
Faceted navigation creating crawl traps
Product variants cannibalising each other
Category pages buried 5+ clicks deep
Product schema missing offers or reviews
Content blogs & publishers
Publishing velocity creates technical debt: archive bloat, slow templates, JavaScript-dependent content and topics competing with themselves.
Typical findings
Tag and archive pages diluting crawl budget
Articles cannibalising the same queries
Core Web Vitals failing on article templates
Article & author schema incomplete
How an engagement runs
Evidence → specification → implementation.
Four steps, one loop. Every engagement starts from data and ends inside your release process — then feeds the next cycle.
01
Diagnose
Logs, crawls, rendering tests and field data reconciled into one model of the site.
02
Architect
Fixes specified as URL rules, template contracts and schema models.
03
Implement
We work inside your sprints: PR reviews, staging QA and CI checks.
04
Compound
Measure each release, guard against regressions, feed the next cycle.
What you actually get
Tickets your developers want to pick up.
No 80-page PDF. Every recommendation arrives as a scoped ticket with evidence, a specification and acceptance criteria — in the tools your team already uses.
Prioritised issue register (impact × effort)

Canonicalise filtered category URLs
PROBLEM
41k parameter URLs (?color=, ?size=) are crawled and indexed, splitting signals from 220 category pages.
EVIDENCE
Server logs: 41% of Googlebot hits on facets. GSC: 18k “Duplicate, Google chose different canonical”.
ACCEPTANCE CRITERIA
<link rel="canonical" href="{{ collection.url }}">
✓ Filter params excluded from canonical
✓ CI check fails if canonical ≠ clean URL

Why an engineer
Why hire an engineer as your technical SEO consultant?
Technical SEO problems are software problems. Rendering, routing, caching, templating and build pipelines decide what search engines can crawl, render and index — long before content or links come into play.
A traditional SEO consultant can tell you that 12,000 pages are “Discovered – currently not indexed”. An engineer can trace it to the pagination component that stopped rendering links server-side two releases ago, write the fix as a ticket, and add a test so it never happens again. That is the difference between a recommendation and a result.
Strategy Digital Node combines IT engineering experience with deep technical SEO specialisation. We read your codebase, server logs and analytics with the same fluency, which means fewer handoffs, faster implementation and SEO that survives the next deploy.

Ask a question
What does a technical SEO consultant do?
A technical SEO consultant makes sure search engines can efficiently crawl, render, index and understand a website. That covers site architecture, JavaScript rendering, Core Web Vitals, structured data, redirects and migrations. At SDN we also turn those findings into engineering tickets and work with your developers until the fixes are live.
Do you implement fixes or only recommend them?
Both. Every audit ships with dev-ready tickets and acceptance criteria. On an implementation engagement we join your sprints, review pull requests, QA changes on staging and set up automated checks so fixes don’t regress.
Which platforms and frameworks do you work with?
Shopify, WooCommerce, Magento / Adobe Commerce, WordPress, headless CMS setups, and JavaScript frameworks including Next.js, Nuxt, React and Angular. If it serves HTML to Googlebot, we can work with it.
How much does a technical SEO audit cost?
Audits are quoted as a fixed scope based on site size, platform complexity and data access. You’ll know the full price before work starts. Book a scoping call and we’ll give you a clear number within a few days.
How long until we see results?
Crawl and indexation fixes often show movement within 2–6 weeks of release. Architecture and performance improvements usually compound over 3–6 months. We report impact release by release, so you can see what moved what.
Can you work directly with our developers or agency?
Yes — that’s the point. We write tickets in your format, join stand-ups or async channels, review PRs and work under your access and security policies. NDAs are standard.
Do you do content writing or link building?
No. SDN is technical only, which keeps us focused. If you need content or digital PR, we’re happy to brief and work alongside your existing partners.
