An SEO agency in Cardiff has to deal with two things most UK cities do not: a capital city made up of very different neighbourhoods, and a bilingual audience. ProntX is a London-based SEO agency that helps Cardiff businesses rank in Google’s map pack, organic results and AI answers, with Welsh and English pages set up properly and prices from £595 a month with no lock-in.

A capital city of local markets

Cardiff had 362,400 residents at the 2021 census, and the wider Cardiff Capital Region has around 1.5 million people. Someone searching from Roath sees a different map pack from someone in Llandaff, Grangetown or Cardiff Bay, and Penarth and Barry, the city’s commuter towns, are separate markets again. About 40 percent of the city’s workforce commute in daily from across South Wales, so many Cardiff businesses also sell to people who live well outside the city.

What the Cardiff search results show

Search “seo agency cardiff” and you see national agencies with Cardiff location pages, directories with listings dated 2024, and roundups written by the agencies that top them. Local pricing guides quote anything from £300 to £6,000 a month. Few pages explain what the money buys, and almost none mention Welsh-language search, even though it affects how a Cardiff site should be built.

Cardiff sectors

Which Cardiff businesses benefit most from SEO?

Finance and business services are the city’s main sector, but media, visitors and a large student population all create their own search demand. Each needs a different SEO plan.

Professional services

Central Square and Callaghan Square

The Central Cardiff Enterprise Zone is a 140-acre business district whose occupiers include Legal & General, Deloitte and the BBC, and Admiral Insurance is one of the city’s major employers. Solicitors, accountants and consultancies here compete with Bristol and London firms for the same clients. Credentials, clear service pages and answers to pre-call questions matter more than map pack tricks. See our B2B SEO approach.

Media and creative

Cardiff Bay and Roath Lock

BBC Cymru Wales, S4C and ITV Wales all have studios in the city, and the independent TV sector runs to over 600 companies. Production, post-production and creative suppliers win work through niche, low-volume searches. Portfolio pages that are crawlable, with real text rather than video alone, are usually the fix.

Visitors and retail

St David’s and the stadium

Cardiff had 21.3 million visitors in 2017, the most of any Welsh destination, and St David’s is the largest shopping centre in Wales. Restaurants, hotels and attractions near the centre and the Principality Stadium compete with booking sites, so local profile work and event-led content published early are where we start.

Students and services

Cathays and the universities

Around 43,900 higher education students live in Cardiff, across Cardiff University, Cardiff Metropolitan University, the University of South Wales and the Royal Welsh College of Music & Drama. Letting agents, gyms, food businesses and tutors in Cathays and Roath see demand peak at the start of each term, so timing content around the academic year pays off.

Welsh-language SEO

Should a Cardiff business have Welsh-language pages?

Only if your customers expect them, but if you add them, build them properly. A half-translated site with broken language links helps nobody and can confuse Google about which page to show.

Who needs them

Welsh speakers in Cardiff rose from 6.6 percent of residents in 1991 to 12.2 percent in 2021, around 42,757 people. Public bodies in Wales work to the Welsh Language Standards; private firms choose. A Welsh version is worth it if you sell to the public sector, work in education or culture, or if Welsh is part of who you are. For many trades and B2B firms, a strong English site comes first.

How we build them

Each Welsh page is paired with its English equivalent and tagged with hreflang using the cy language code, so Google treats them as translations rather than duplicates. Following university guidance on bilingual sites, the Cymraeg and English link on every page goes to the matching page, not the homepage, and both versions go live together. It is far easier to plan this from the start, which is why we review structure in our technical SEO work before translating anything.

Local SEO

How do you rank across Cardiff districts and nearby towns?

By being realistic about distance. Google weighs how close a business is to the searcher, so your address sets the area where map pack rankings are easiest, and content and links widen the net.

A business in Canton can usually win nearby searches in Pontcanna, Riverside and Llandaff with a well-built profile, steady reviews and the right categories. Reaching Penylan, Splott or Cardiff Bay takes stronger signals, and Penarth, Barry or Newport are separate markets. We only build area pages where you have real work, reviews or local detail to show, because thin pages that swap the place name can be treated as doorway pages.

For businesses that cover the whole Capital Region, such as trades, removals or home services, we combine a service-area profile with strong area pages and, where it makes sense, PPC in Cardiff to cover places organic search cannot yet reach. Our local SEO page explains the ranking factors in more detail.

FAQ

Cardiff SEO questions, answered

Still unsure? Ask us anything. We reply within one working day.

How much does SEO cost in Cardiff?

Local pricing guides quote anything from about £300 to £6,000 a month, which shows how little the word SEO tells you on its own. ProntX starts from £595 a month for one location, with multi-area and bilingual plans typically £900 to £1,600. Whoever you speak to, ask for a written list of the work done each month so you can compare like with like.

Do I need a Welsh-language version of my website to rank in Cardiff?

Not to rank for English searches, which are the large majority in Cardiff. A Welsh version makes sense if your customers expect it, if you work with public bodies, or if Welsh is part of your brand. If you add one, it should be complete, properly linked page to page and tagged with hreflang, not a thin machine translation of a few pages.

Will Google show my Welsh pages to Welsh speakers?

Google uses the language of the page and the search, so a properly marked-up Welsh page can appear for Welsh-language searches while the English page serves everyone else. Hreflang tags using the cy code tell Google the two pages are translations of each other, so they support rather than compete with each other. We check the set-up as part of our technical work.

Can one Cardiff business rank in Penarth, Barry and Newport too?

Organically, yes, with useful pages for the places you genuinely serve. In the map pack it is harder, because Google weighs how close a business is to the searcher. A Canton address will not usually win the Barry map pack on profile work alone. We combine a service-area profile, honest area pages and, if needed, paid search to cover the gaps.

How long does SEO take for a Cardiff business?

Map pack improvements from Google Business Profile, review and citation work often show within two to three months for less competitive services. Ranking across the city centre for terms like solicitors or accountants takes longer, typically six to twelve months, because established firms have years of links and content. Our reports track enquiries by area so you see progress early.

Why would a Cardiff business use a London SEO agency?

Because the work happens on your website and profiles, not in a meeting room. You get senior specialists, published prices and a contract you can end with a month's notice. We have no Cardiff office and do not claim one. Clients work with us by video call and a shared dashboard, and Cardiff Central has direct trains to London Paddington when a visit helps.

Are SEO directories and top ten lists a good way to choose an agency?

They are a starting point, but many Cardiff lists are written or paid for by the agencies that appear in them, and several directory pages are dated 2024. Look instead for named case studies you can check, a clear monthly scope, who owns the accounts and how long the contract runs. Our free audit shows how we think before you commit.

Do you guarantee first place on Google in Cardiff?

No, and you should be wary of anyone who does. Rankings depend on Google's algorithm, your competitors and your starting point, none of which an agency controls. What we commit to is the work: a written plan, the tasks in your monthly scope, and an honest report of calls, forms and rankings so you can judge whether it is paying back.
