Technical SEO Agency
in Cardiff
Technical SEO that actually fixes the crawl problem, not just renames it.
Cardiff technical SEO is usually the hidden drag on otherwise-decent content programmes. Cathays university spin-outs, Cardiff Bay media platforms and Welsh Government-adjacent sites all carry structural debt that blocks ranking. TML runs deep technical SEO for Welsh capital brands — log-file analysis, Core Web Vitals, rendering, schema — handled by engineers, not a checklist-running audit template.

Quick Answer
Most Cardiff sites we inherit have at least one serious technical drag blocking otherwise-decent content. Cathays university spin-outs tend to have JavaScript rendering issues on React-heavy builds. Cardiff Bay media sites carry indexation bloat from years of legacy content and accidental URL parameters. Welsh Government-adjacent and public-sector sites often have accessibility and crawl-budget issues baked in from CMS choices made a decade ago.

Technical SEO Agency in Cardiff
Technical SEO in Cardiff.
01
Your Technical SEO Partner in Cardiff.
Most Cardiff sites we inherit have at least one serious technical drag blocking otherwise-decent content. Cathays university spin-outs tend to have JavaScript rendering issues on React-heavy builds. Cardiff Bay media sites carry indexation bloat from years of legacy content and accidental URL parameters. Welsh Government-adjacent and public-sector sites often have accessibility and crawl-budget issues baked in from CMS choices made a decade ago.
Our Cardiff technical SEO engagements begin with a proper log-file pull and a crawl-vs-rendered-DOM comparison. We're looking for the real problems — orphaned URLs consuming crawl budget, pages rendering client-side that Google can't read, broken internal linking, schema conflicts, and Core Web Vitals regressions tied to specific template changes. The output is a prioritised fix list with effort estimates, not a 100-item laundry list nobody acts on.
We work with your engineering team directly — we give Jira-ready tickets, acceptance criteria and test steps rather than vague recommendations. For clients without in-house engineering we handle implementation end-to-end on WordPress, Webflow or headless stacks. Retainers run as ongoing technical governance rather than one-off audits, because technical health degrades between releases and needs watching.

Technical SEO Market in Cardiff.
mediafinancegovernmenteducationtourismtech
Cardiff is home to thriving media, finance, government industries, and each requires a unique technical seo approach. With a diverse economy driven by media, finance, government, education, businesses are increasingly turning to digital solutions to stay competitive.
The competitive landscape in Cardiff is evolving rapidly. At TML, we help you navigate this by identifying gaps in your competitors' strategies and positioning your brand where it matters most.
Cardiff has a handful of generalist digital agencies offering technical SEO as a line item, a few senior freelance consultants operating from Cathays and Pontcanna, and Bristol specialist shops pitching down at £4-8k monthly. TML's position is engineering-led technical SEO at roughly half Bristol pricing, with senior leads who read your stack directly.
03
Case Study.
A Cardiff Bay media platform had 47,000 URLs indexed and was ranking for almost nothing commercial. Log-file analysis showed Googlebot spending over 60% of its crawl budget on faceted-search URL parameters that returned near-duplicate content. We consolidated canonicals, blocked parameter crawling at robots.txt level, and restructured the template schema. Three months on, indexed URLs had dropped to 12,000, crawl budget was hitting the pages that mattered, and priority commercial terms had moved into the top ten.
Cardiff Market Insights
70%
of Cardiff sites we audit have a Core Web Vitals or rendering issue blocking top-10 rankings
Across two years of Cardiff technical audits the pattern is consistent — otherwise-strong content programmes are held back by a small number of fixable technical issues. Cathays-area spin-outs tend to have rendering problems; Cardiff Bay media sites carry indexation bloat. Fixing these usually produces ranking movement within six weeks of deployment, before any new content is added.

FAQ
What Cardiff clients ask about our Technical SEO company.
What's included in a Cardiff technical SEO audit?
+
Log-file analysis, crawl vs rendered DOM comparison, Core Web Vitals review on representative templates, schema audit, internal linking analysis, indexation and canonical review, and a prioritised fix list with effort estimates. Delivered as Jira-ready tickets for implementation, not just a PDF.
How long until we see ranking improvements after fixes deploy?
+
Most Cardiff clients see movement within 6-10 weeks on queries where the technical issue was the primary drag. More competitive terms still need content and link investment, but technical fixes alone routinely lift mid-tier commercial terms into the top ten within a quarter.
Can you work directly with our engineering team?
+
Yes — that's how we prefer to run engagements. We write tickets in the format your team uses, attend sprint planning if useful, and deliver acceptance criteria so QA can verify. We'll also implement ourselves on WordPress or headless stacks if you don't have internal engineering.
Do you handle Core Web Vitals specifically?
+
Yes — LCP, INP and CLS are usually the highest-leverage technical work for Cardiff commercial sites. We profile the real issues (often third-party script bloat or unoptimised hero images) and deliver fixes rather than chasing theoretical scores that don't move rankings.
How much does a technical SEO audit cost?
+
One-off senior-led audits run £2,500-6,000 depending on site scale and complexity. Ongoing technical SEO retainers — monthly governance, post-release checks, Core Web Vitals monitoring — run £1,500-3,500 monthly. Below Bristol-specialist pricing for equivalent engineering depth.
