/ Technical SEO consultant for product and engineering teams

A senior technical SEO consultant for your engineers.

Your developers can build anything. What they need is a senior technical SEO consultant who knows how Googlebot treats React, Next.js and headless builds, and who can review architecture, plan migrations and read server logs alongside them. You keep the implementation. We bring the judgement.

/ Sound familiar?

Strong engineers. Blind spots in search.

Engineering teams make decisions every week that shape how Google sees the site. Most of them get made without anyone in the room who knows search.

Next.js went live, rankings didn't follow

The new frontend is fast and modern, but some routes render client side, metadata is set in JavaScript and Google indexes a fraction of what you expected.

Architecture decided before SEO was asked

Headless CMS, new URL patterns, a separate docs subdomain. The choices were made in a design doc, and SEO was consulted after the code was written.

A launch date, but no migration plan

Go-live is weeks away. There's no redirect map yet, nobody has crawled staging, and the team is unsure what Google will do on day one.

Server logs nobody has read

Your servers record every Googlebot request, yet nobody has looked. Crawl budget could be going to parameters, staging copies or long-dead URLs.

We sit with your engineers at the moment decisions get made, and give them answers they can build.

/ What's included

Five ways to work with a technical SEO consultant.

Choose a format by the question you need answered. Each is led by a senior consultant, and your team keeps ownership of the code.

Architecture review

Before you commit to a new stack, URL scheme or CMS, a technical SEO consultant reviews the design with your tech lead. We look at routing, rendering, URL patterns, internationalisation and how content travels from CMS to HTML.

Why it matters: changing a URL scheme in a design document takes an hour, but changing it after launch means redirects, lost links and months.

What you get
  • Review of design docs, RFCs or architecture diagrams
  • URL scheme and routing rules checked for crawlability
  • Subdomain or subfolder decisions for blog, docs and shop
  • Headless CMS content flow traced to the final HTML
  • Written recommendations with trade-offs, not just rules
  • A follow-up session once your team has questions

/ How it works

How a consulting engagement runs.

Short, focused and built around a decision. Here's the usual shape of the work, which we adjust to your deadline.

1Day 1

Scoping call

A call with your tech lead or product owner to define the question, the deadline and what a useful answer looks like.

You get: a written scope and the access we need.

2Week 1

Investigation

We crawl, render, read logs or review design documents, depending on the question, and test assumptions against your live site.

You get: evidence, not opinions, behind every recommendation.

3Week 2

Working session

A session with your engineers to walk through findings, argue the trade-offs and agree what gets built.

You get: recommendations your team has already stress-tested.

4Afterwards

Review and follow-up

We review the pull requests or staging build that come out of it, and stay on call for questions.

You get: confidence that what shipped matches what was agreed.

/ Results

Advice grounded in real results.

The advice comes from the same playbook our specialists apply on client sites. Over 16 months on four ecommerce stores, that playbook delivered the numbers below, built on technical foundations.

/ Is this for you?

A consultant makes sense for teams with:

✓A great fit if you are

  • An engineering team with capacity that can implement once it knows what to build
  • A framework or CMS decision ahead such as Next.js, Nuxt or a headless CMS
  • A migration on the calendar and no SEO plan for it yet
  • An in-house SEO without deep technical skills who needs a senior sparring partner
  • A question that needs a second opinion before money or code gets committed

✕Probably not a fit if you

  • Have no developers to implement. Our technical SEO services include implementation
  • Need monitoring for years to come. A technical SEO company setup suits that better
  • Want content strategy, not engineering. Try our SEO consultant page
  • Want someone to rubber-stamp a plan. We'll tell you when we disagree

/ Before you hire

When to hire a technical SEO consultant.

Hiring a consultant pays off at specific moments and wastes money at others. Below are the situations where a single senior opinion saves the most time, budget and traffic.

01

Before choosing a framework or CMS

Rendering, routing and URL decisions are cheap to change on paper and expensive after launch. A few hours of review before the design is final avoids months of workarounds.

02

Three months before a migration

That's enough time to inventory URLs, write redirect rules, test staging and fix what breaks. Bring help in the week before launch and you can only limit the damage.

03

When traffic drops with no clear cause

If Search Console shows indexing falling and nobody can explain why, someone who reads logs and rendered HTML usually finds the cause faster than another tool will.

04

When your team disagrees

Engineers want client-side rendering, marketing wants search visibility. An outside technical SEO expert can test both positions against the real site and settle it with evidence.

05

When you have builders but no SEO lead

If developers can ship but nobody owns technical SEO, a consultant can set rules, review work and train the team until someone in-house can take over.

If you need the work done rather than advised, a consultant is the wrong hire. Look for a team that implements.

/ Your options

Consultant, agency, or in-house?

The right choice depends on who will write the code. Here's how the options compare for engineering-led teams.

Cost Hourly, varies widely Monthly retainer A full salary plus tools ✓Fixed quote per engagement

/ Questions

Questions about consulting formats.

What does a technical SEO consultant actually do?
Advises the people who build your site. That means reviewing architecture, testing rendering, planning migrations, reading logs and checking pull requests, then explaining what to change and why. Implementation stays with your team. If you want us to do the work instead, see our technical SEO services.
Who will be our technical SEO consultant?
Andrej Zafirov, our founder, leads consulting, or a senior technical specialist from our SEO agency takes the engagement, depending on the question and your stack. You talk to the person doing the analysis from the first call onward. There's no handover to a junior once you sign.
Do you implement changes, or only advise?
In a consulting engagement we advise and review, and your developers implement. If your team runs out of capacity, our technical SEO agency team can take on tickets, open pull requests or edit Shopify, WordPress and Webflow directly. You can switch between the two as needs change.
Can you advise on Next.js, Nuxt or a headless setup?
Yes. We test what Googlebot receives on each route type and advise on server rendering, static generation or prerendering per template. We also check metadata, canonicals, hreflang and internal links in the server response, which is where most headless and single-page app issues hide.
How does technical SEO consulting for a migration work?
We build the URL inventory with you, write redirect mapping rules your developers can implement, review staging before the launch date is fixed, give you a launch-day runbook, and watch indexing for weeks afterwards. Ideally we start about three months before go-live, though shorter timelines are possible.
How available are you between sessions?
We reply within one business day, and usually faster in a shared Slack or Teams channel. For engagements with on-call advice, we agree the expected response time up front. Launch days and urgent drops get priority, so tell us your dates early and we'll plan around them.
What do you need from us to start?
A clear question, Search Console access, and whatever the question touches: staging access, design documents, a sample of server logs or a read-only view of the repository. We'll list exactly what we need after the scoping call, and nothing more.
When should we hire a technical SEO company instead of a technical SEO expert?
When you need years of steady care rather than answers to specific questions. A technical SEO company relationship covers monitoring, release checks and documentation. A technical SEO expert in a consulting role is best for decisions, reviews and teaching your team.
