Technical SEO Agency
Search engines see a different site from the one you built. We close the gap. Our technical SEO services have delivered lossless migrations and increased revenue for our clients.
Nothing else in SEO works if search engines can’t access your site properly. We start with the foundations.
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. This means more of the traffic we win turns into enquiries and sales.
How we work with you
We come to you.
Every engagement starts with you. 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.
We start with a crawl of your full sitemap. We make sure to track where we want customers to land and the journeys they should take to a sale.
We fix the foundations.
We fix crawling, indexing, speed, structure, migrations. In that order. That’s non-negotiable.
We show you what’s moving.
Clear monthly reporting, talked through by the people doing the work. We check your web vitals and PageSpeed every week and aim to have you as close to 100 as possible. We did it for ourselves, so why not you?
Technical SEO services that decide whether anything else lands
Crawling and indexation
We find what search engines can’t reach and index it if that’s not intentional. Don’t waste your crawl budget if the page won’t help.
Site architecture
Shorter routes to the pages that earn money, with internal links that push authority where you want it to go.
Page experience
Everything that matters to your users. A quick-loading page that doesn’t compromise on quality.
Structured data and entities
Schema that makes it clear what & who a page is for. No, we don’t forget about FAQs.
JavaScript rendering
If your content only exists once the JavaScript has run, we check that Google and the AI crawlers can see it.
Migrations and releases
Most of the traffic we’re asked to recover was lost on a launch day. We put in a thorough plan with redirect mapping to deliver lossless migrations.
WordPress
Plugin load, archive pages nobody meant to publish and page builder markup that makes a simple page heavy.
Shopify
Every product, every category, everything that increases your sales. Nothing short of success.
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. 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 and your developer capacity. Your release schedule becomes a roadmap your team can ship.
Prove the fix landed
It’s not enough to make the change. We crawl and crawl again to prove it worked and continues to work.

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.
Our expertise
Google Search
When your audience moves from AI answers to deeper research, we make sure your brand dominates the traditional results page.
Data Insights
We define exactly who your search presence is built for, so every decision that follows is designed to attract people capable of engaging, converting and driving real business value.
AI Search
We build content around real questions and clear, authoritative answers, structured so AI models recognise, trust and recommend your brand.
Social Search
Social Search makes your brand genuinely searchable and discoverable in the places modern audiences now turn to for answers, recommendations and inspiration.
Digital PR
Stories the press actually wants, and the links and brand mentions that follow, supporting SEO growth and long term brand value at the same time.
Conversion
We analyse behaviour, remove friction and tighten your funnels so more visitors convert. Higher sales, higher ROI and a website that works as hard as your marketing.
What you should get from your technical SEO agency
Clear, unquestionable results
Technical SEO is unique because the results are either there or not. If they are, they are immediately. The numbers either stay strong after a replatform or they don’t. AlumierMD migrated across three territories and maintained a site health score above 95, while organic clicks increased by 7.5% and click-through rate went up by 25.8%.
The best option, not the prettiest
We’ll let you know when the solution isn’t exciting. We create great content, but sometimes the real fix is sorting out how pagination creates URLs. We handle that as well. Buzz Capital’s site achieved a perfect 100 on Core Web Vitals and grew from almost no visibility to over 480 commercial keywords. Most of that success came from better structure.
No PPC or paid social
We don’t offer PPC or paid social services. We focus on giving you the best website, both in what visitors see and how it’s built behind the scenes.
Frequently asked questions
What is technical SEO?
For a page to rank or show up in an AI answer, a crawler needs to find it and understand what’s there. Technical SEO includes everything that affects this, like crawl paths, indexing, site speed, and structured data. Even the best design and copy won’t matter if search engines can’t access your site.
Why does technical SEO matter?
Technical SEO limits how far your site can go. You might have great content and strong links, but a rendering issue or a stray noindex tag can still keep important pages out of search results. Technical fixes are often the cheapest way to grow, since the traffic is already there but something is stopping it.
Will I deal with a technical SEO expert directly?
A senior technical SEO specialist manages your account, does the audit, and handles the fixes personally. You’ll talk to the same expert from the first crawl to the final re-crawl, so nothing gets missed.
What does your audit cover?
Our audit includes over 80 checks, starting with how Googlebot accesses and renders your site right now. We rank each issue by its commercial impact and explain our reasoning, so your developers can review it before spending time. If you need a one-off audit, we offer that too with our SEO audit services.
How do you work with our developers?
Each recommendation comes as a ticket your developers can use, with the fix and a clear way to test it. We’ll use whatever format your team prefers and are happy to join stand-ups or release planning if needed. A good technical SEO agency will also tell you clearly when an issue isn’t worth your developers’ time.
How do you report on technical SEO?
When you start with us, we set up a live dashboard based on your goals so that you can check progress anytime. Your technical SEO expert also sends weekly email updates, plus monthly and quarterly reports. We track every fix through to a re-crawl, so you can see that the change is live on your site.
Do you provide technical SEO services across the UK?
We’re a technical SEO company based in Sheffield, but we work with brands all over the UK, from local retailers to businesses in multiple countries. We handle crawls, audits, and developer handovers remotely, so your location never slows us down. That’s how we managed AlumierMD’s migration across the UK, US, and Canada as one project.
How much does technical SEO cost?
We charge a fixed retainer starting at £3,000 per month. Most technical work happens up front, so migrations or crawl issues usually cost more in the first quarter and less after fixes are done. Our proposals break down one-off repairs and ongoing support, so you know exactly what you’re paying for.
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.
