Technical SEO South Wales

Most SEO problems are invisible.
Until you know where to look.

A Wales business can have well-written service pages, a decent Google Business Profile, and genuine customer reviews — and still sit on page three. Often the reason is not the content. It is what is happening underneath: crawl errors Google has quietly logged, redirect chains that bleed link equity, Core Web Vitals scores that push the site down in mobile rankings, or schema that is broken and doing nothing.

Technical SEO is the work that fixes the foundation. Once Google can properly access, understand, and evaluate your pages, everything else starts to work harder — content ranks better, links pass value, and local signals land with more weight.

BLACKdot is a technical SEO agency working with businesses across Wales and South Wales. Every engagement starts with a full site audit. Every month you get a plain-English report on what was fixed and what changed, not a dashboard full of numbers that do not connect to your business.

The reality

Good content.
Still not ranking.

Technical issues are the most common reason high-quality websites underperform in search. Google cannot rank what it cannot properly read.

43%

of websites have crawl errors that affect indexation

53%

of mobile visits are abandoned if a page takes over 3 seconds to load

0.6%

of searchers click anything on page two

Fix the foundation. Everything else works harder.

What I Actually Do

Three technical SEO services that make a real difference

Technical SEO covers a lot of ground. Here is where most of the work happens for Wales businesses.

Technical SEO Audit

Most websites have technical issues that are completely invisible to the people who own them. Crawl errors, broken internal links, slow page load times, missing canonical tags, duplicate content, redirect chains, hreflang errors — Google sees all of this, even when you do not. A technical SEO audit maps every issue across your site, ranks them by impact, and tells you exactly what to fix and in what order.

Right for

Any Wales business whose site is not ranking despite decent content, or any site that has never had a full technical review.

Core Web Vitals and Site Speed

Google uses Core Web Vitals as a direct ranking factor. Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift are measurable scores that tell Google how your site performs for real users. Poor scores do not just hurt rankings — they hurt conversions. A slow, unstable page loses customers before they even read a word. I identify exactly what is dragging your scores down and fix it.

Right for

Wales businesses losing rankings or conversions to sites that are noticeably faster and more stable on mobile.

Structured Data and Schema Markup

Schema markup tells Google what your content is about in language it can act on. FAQ schema, local business schema, service schema, review schema — implemented correctly, these can produce rich results in search listings and strengthen how Google understands your business. Most Wales websites have no schema at all, or schema that is broken and doing nothing. I implement it properly, test it, and monitor it.

Right for

Businesses who want to improve their appearance in search results and help Google better understand their services and location.

How It Works

How it works, start to finish

Audit

Before anything else, I run a full crawl of your site and review Search Console data. Every technical issue is documented, categorised, and ranked by impact.

Prioritise

Not every technical issue is equal. I identify the fixes that will have the biggest positive impact on your rankings and site health, and we tackle those first.

Implement

Fixes go in. Crawl errors resolved, schema added, page speed improvements made, redirect chains cleared. Month by month, the technical foundation gets stronger.

Report and Refine

Every month you get a plain-English report: what was done, what changed, and what's next. I adjust based on what Search Console and crawl data shows.

Technical SEO that shows up in your rankings, not just your audit report.

Every plan includes Search Console monitoring and monthly reporting on what actually changed.

Common Questions

Questions Wales businesses ask about technical SEO

Technical SEO is the work that makes your website readable, crawlable, and indexable by search engines. It covers things like page speed, site structure, schema markup, crawl errors, and Core Web Vitals. Good content cannot rank well if Google cannot properly access and understand your pages. Technical SEO removes those barriers.

For most Wales business websites, a full written technical audit takes around five to seven working days. You will receive a detailed report covering every issue found, ranked by priority, with clear guidance on what to fix and why.

That depends on your site. A one-off audit tells you what is wrong. An ongoing retainer fixes those issues and monitors for new ones as your site grows and Google updates its requirements. Most businesses benefit from at least three months of ongoing work to resolve everything the audit uncovers.

Core Web Vitals are a set of speed and usability metrics Google uses as a ranking signal. They measure how quickly your page loads for real users (LCP), how responsive it is to interaction (INP), and how visually stable it is (CLS). Poor scores can directly suppress your rankings and increase bounce rates. Yes, they matter.

Yes. I work with businesses in Cardiff, Swansea, Newport, Bridgend, the Valleys, and across Wales. Technical SEO work is done remotely, so location is no barrier. Results show up wherever your customers are searching.

Yes. Most Wales business websites run on WordPress or Shopify, and both have well-documented technical SEO requirements. Whether it's plugin conflicts, theme performance issues, crawl budget waste, or schema gaps, I've seen and fixed it before.
