Nothing else in SEO works if search engines can’t crawl, render and index your site properly, which is why technical foundations are where we start.

A faster, cleaner site converts better

Slow pages lose buyers

Every extra second a page takes to load gives a buyer time to leave. Speed and layout fixes protect your rankings and keep hold of the people those rankings bring in.

The proof is in the revenue

PRYA’s roadmap started with site speed. Its conversion rate rose 37% and product revenue rose 45%. Peter Tyson grew revenue 149% from technical SEO.

Then we work on conversion

Once the site is fast and stable, our conversion rate optimisation team tests the pages themselves, so more of the traffic we win turns into enquiries and sales.

How we work with you

We come to you.

Every engagement starts in person, at your business. We sit down with your team, sales included, to learn who buys from you, why they buy and what makes you different.

We crawl it the way Google does.

A full crawl, your server logs and Search Console show what Google reaches, what it wastes time on and what it never sees. That becomes the plan.

We fix the foundations.

Crawling, indexing, speed, structure and migrations, fixed in priority order so search engines can reach, render and index every page that matters.

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

Crawl and index audit

An 80+ point audit that starts with how Googlebot sees 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.

Who else we’ve done it for

Circulate worked with us, a homecare agency, for over 2 years. In that time they helped optimise our web content for SEO as well as undertaking technical SEO tasks. The communication was clear and they responded quickly to ad hoc questions and tasks. A pleasure to work with this friendly company who felt like part of the team.

What a technical SEO agency should be able to show you

Ask for the migrations

Ask for the migrations. Technical SEO is the one discipline where the work provides clear, immediate proof. 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%.

Sometimes the fix is unglamorous

We’ll tell you when the answer is unglamorous. We provide great content, but sometimes you need to fix how pagination generates URLs. We do that too. Buzz Capital’s site scored 100 on Core Web Vitals and went from almost no visibility to more than 480 commercial keywords. Most of that came from structure.

No PPC or paid social

We don’t run PPC or paid social. Everything we do is focused on delivering you the best website in both what you can see and the structure it’s built on.

Frequently asked questions

What is technical SEO?

Before a page can rank or appear in an AI answer, a crawler has to reach it and make sense of what it finds. Technical SEO covers everything that affects that process, from crawl paths and indexing to site speed and structured data. Good design and strong copy count for very little if the machines reading your site can’t get to them.

Why does technical SEO matter?

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.

Will I deal with a technical SEO expert directly?

Every account is run by a senior technical SEO specialist who carries out the audit and works through the fixes themselves. You speak to that same person from the first crawl to the final re-crawl, so nothing gets lost along the way.

What does your audit cover?

Our audit runs more than 80 checks, starting with how Googlebot accesses and renders your site today. We rank each finding by commercial impact and show the reasoning so your developers can question it before committing time. If you only need the audit as a one-off project, our SEO audit services cover that.

How do you work with our developers?

Every recommendation arrives as a ticket your developers can build from, with the fix and a testing method spelt out. We’ll use whatever format your team already works in and happily join stand-ups or release planning when that helps. Part of a good technical SEO agency’s job is to tell you plainly when an issue isn’t worth your developers’ time.

How do you report on technical SEO?

During onboarding, we build a live dashboard around your goals, so you can check progress whenever you like. Your technical SEO expert also sends a weekly email update, alongside monthly & quarterly reports. We track every fix through to a re-crawl, so you can see the change made it to the live site.

Do you provide technical SEO services across the UK?

As a technical SEO company based in Sheffield, we work with brands across the UK, from single-market retailers to businesses trading in several countries. We run crawls, audits and developer handovers remotely, so your location doesn’t affect how quickly we deliver. That’s why we could run AlumierMD’s migration across the UK, the US and Canada as a single project.

How much does technical SEO cost?

We work on a fixed retainer starting at £3,000 p/m. Technical work tends to front-load, with migrations or crawl problems costing more in the first quarter and less once fixes are live. Our proposals separate the one-off repair work from the ongoing support, so you can see exactly where the fee goes.

Start with a free strategy session

We’ll look at what you rank for, where competitors are winning instead, and what is worth fixing first. No charge, and the findings are yours either way. We look at your whole search marketing mix, not just one channel.
