Technical SEO Agency

Search engines see a different site to the one you built. We close the gap. Book a free strategy session with a technical SEO consultant and we’ll show you what Google can’t see.

Circulate Digital reviews on Trustpilot

Crawling, indexation and rendering decide whether your content gets a fair hearing. Get those right and everything else you do in search starts working harder.

Nothing else in SEO works if search engines can’t read your site, so it is where we start. Peter Tyson grew revenue 149% once we fixed its technical foundations.

What we fix

Technical SEO services that decide whether anything else lands

Crawling and indexation

We find what search engines can’t reach, what they’re wasting time on, and what’s sitting outside the index by accident rather than by choice.

Site architecture

Shorter routes to the pages that earn money, and internal links that push authority where you actually want it to go.

Page experience

Speed, layout stability and mobile usability, judged on what real visitors experience rather than a lab score on a good day.

Structured data and entities

Schema that spells out what you sell, who you help and why you’re credible, so machines don’t have to guess.

JavaScript rendering

If your content only exists once the JavaScript has run, we check that Google and the AI crawlers genuinely see it.

Migrations and releases

Redirect maps, staging checks and a rollback plan. Most of the traffic we’re asked to recover was lost on a launch day. Visit SEO migration

WordPress

Plugin load, archive pages nobody meant to publish and page builder markup that makes a simple page heavy. Visit WordPress SEO

Shopify

Collection architecture, the duplicate paths that tags and filters create, and app scripts loading on every page. Visit Shopify SEO

Everything well built starts underneath.

Crawl paths, indexation, rendering and speed decide whether anything you publish is ever seen. We fix the layer your customers never look at and every search engine judges you on.

How we work

Crawl and index audit

An 80+ point audit that starts with how search engines and AI crawlers see your site today. What they can reach, where crawl budget goes, and what’s staying out of the index.

Prioritise by commercial impact

Not every issue is worth fixing. We map each finding against the pages that make you money, so the roadmap leads with what’s holding rankings back rather than what’s easiest to spot.

Fit the roadmap to your team

We learn your CMS quirks, your release cycle and your developer capacity. A roadmap your team can ship beats a wish list that stalls at handover.

Prove the fix landed

Re-crawls, rendering checks and index coverage tracking. We show you the change worked, not just that it went live.

The first crawler you need to please is no longer Google’s.

AI assistants read your markup, your structure and your entities long before they quote you. The work that makes a site legible to Google is the same work that makes it quotable in an AI answer.

Technical SEO is where AI readiness starts

AI assistants answer from pages they can reach, render and read. If a crawler can’t get a clean copy of the page, nothing on it counts, however good the writing is.

So AI visibility starts as a technical SEO problem. We open crawl paths for the assistant bots, fix content that only appears once JavaScript runs, and get your structured data saying the same thing as the page it describes.

Then we track which assistants quote you and which ones skip you, so you can see what the technical work bought.

AlumierMD

3territories migrated in one move

A medical grade skincare brand active across the UK, US and Canada needed to scale without losing what it had built. We planned and ran the migration across all three territories and protected rankings through the switch.

Why trust us with it

What a technical SEO agency should be able to show you

Ask for the migrations. Technical SEO is the one discipline where the work is either provable or it isn’t, because the numbers either hold through a replatform or they don’t. Corndel moved their whole site to a new CMS with us and came out the other side with domain authority stable at 40 and referring domains flat at 328 to 324. AlumierMD migrated across three territories and kept a site health score above 95 while organic clicks rose 7.5% and click-through rate rose 25.8%.

The work is done by the person who audited your site. Matt leads the search work and stays on the accounts he scopes, which matters on technical work because the person who found the crawl trap is the person who knows why it was there. We stay small enough for that to keep being true.

We will tell you when the answer is unglamorous. Plenty of sites we audit do not need a content programme, they need a fix to the way pagination generates URLs. Buzz Capital’s site scored 100 on Core Web Vitals and went from almost no visibility to more than 480 commercial keywords, and most of that came from structure rather than volume of output.

We do not run PPC or paid social, so nothing in a technical SEO scope is there to feed another channel.

Frequently asked questions

What is technical SEO?

Technical SEO is the work that makes your site easy for search engines and AI crawlers to reach, read and understand. Sitemaps, crawl paths, indexation, site speed, rendering, structured data and site architecture all sit under it. Design and content can be excellent and still earn nothing if the machines reading your site can’t get to them.

Why does technical SEO matter?

Because it sets the ceiling on everything else. You can publish strong content and earn good links, and a rendering fault or a stray noindex will still keep the pages you care about out of the results. Technical work is also the cheapest growth available on most sites, since the traffic is already earned and something is blocking it.

What does your audit cover?

More than 80 checks, grouped into crawl access, indexation, architecture and internal linking, rendering, page experience, structured data and entity signals, and AI crawler access. You get findings ranked by commercial impact rather than by severity score, with the reasoning shown so your team can challenge it.

How do you work with our developers?

We write tickets, not recommendations. Each item comes with the problem, the fix, how to test it and how we’ll verify it afterwards, in whatever format your team already uses. We’ll join stand ups and release planning if that helps, and we’ll tell you when something is not worth your developers’ time.

How do you report on technical SEO?

You get a live dashboard built around your goals during onboarding, so progress is visible at any point rather than once a month. On top of that, your account manager sends a weekly email update, a monthly report and runs a scheduled catch up. Every fix is tracked through to a re-crawl, so you can see it landed.

How much does technical SEO cost?

We scope every retainer to your site, so there’s no price list. Technical work tends to front-load: a site carrying a migration or a crawl problem costs more in the first quarter and less afterwards, once the fixes are in. We scope against the state of the site rather than a headcount, so you can see which part of the fee is one-off repair and which is ongoing.

Let’s look at your foundations

We’ll come back with what’s holding your site back, before you commit to anything.
