Social Media Marketing Agency in Cardiff

Cardiff is a capital that still feels like a local. That mix is exactly what its brands should sound like.

7SEA is a social media marketing agency for Cardiff brands and service businesses: a monthly calendar you approve, daily posting and DM handling, and plain written reporting.

In short

What is social media marketing in Cardiff?

Social media marketing in Cardiff is the work of serving Wales's capital and its tight-knit local market at once. Government, media and the universities give the city capital-grade money, match days turn it into a stadium with streets, and Welsh identity, language included where it fits, separates brands that belong from brands passing through.

Platforms

Platform mix for a Cardiff business

We would rather run three accounts well than seven badly. Which three depends on your category and your city, not on which platforms are being talked about this year.

Platform Who it reaches Where it fits
Instagram Consumer Cardiff and match-day visitors First platform for food, retail and events
Facebook Family suburbs and community groups Strong here; services and trades
TikTok The student mass Second platform in term time
LinkedIn Government, media and professional services First platform for B2B
YouTube Shorts Visitors planning big weekends Discovery content around fixtures

On the ground

What moves a Cardiff account

Match days are the city's pulse. International rugby weekends flood the centre and move hospitality demand like nothing else in Britain relative to city size. Businesses that plan content and capacity around the fixture list win days worth weeks.

Welsh identity is an asset, used honestly. A genuine nod to Welsh language and culture, where it fits the brand, lands warmly here. Token Welsh pasted on for marketing reads instantly as what it is.

The capital economy is the stable base. The Senedd, the BBC's drama production hub and the universities give Cardiff year-round professional and student audiences that keep demand steady between the big weekends.

What is included

What the social media management package includes, every month.

Community management is included rather than sold as an add-on, because an account with unanswered DMs is worse than no account at all.

Current accounts, competitors and audience reviewed. Content pillars and tone of voice agreed.

Week 1

02

Shoot

A production day for the quarter's photography and video, planned against the pillars.

Questions

Social media questions.

If yours is not here, send it. We answer these on the first call anyway.

How much does social media management cost in Cardiff?

7SEA retainers in Cardiff start at £1,000 a month, scoped after we review your accounts, your category and how much content already exists. You approve the number before anything starts, and the contract is rolling on 30 days with no lock-in.

How many social media platforms do you manage?

We work across Instagram, TikTok, Facebook, LinkedIn, YouTube and Pinterest. Most brands run two or three of them properly rather than all six thinly, and which two or three depends on your category and where buyers in your city actually spend their time.

What type of content do you create?

Statics, carousels, reels and stories, mixed to suit the platform and the goal. Reels and short video do the discovery work, carousels explain and teach, statics carry offers and brand, and stories handle the day to day.

Do you use AI to design social media content?

Yes, as a production tool. The difference is the output: our AI work is finished to look like real photography and real design, not the obvious AI look most tools produce. You can review samples before committing.

We have no photos or raw content. Can you still run our social media?

Yes. Where raw content does not exist we build the calendar from AI-produced visuals and copyright-free stock, finished to match your brand. Once we have shoot material from you, it replaces that mix gradually rather than all at once.

What do we actually receive each month?

A content calendar approved before anything publishes, then 15 to 30 pieces of finished content depending on scope, scheduled and published, with comments and DMs handled daily and a monthly report on what moved.

What is your process for social media management in Cardiff?

Audit of your accounts and three local competitors, a one-page strategy, then a monthly calendar you approve before anything posts, with the fixture list built in where match days move your demand. Daily publishing and DM handling, and a plain written report.

Is social media marketing worth it for a small business in Cardiff?

Yes, on two rhythms. Match weekends reward businesses whose content and offers are ready before the city fills, and the capital's steady professional and student base rewards consistency the rest of the year.

Which social media platform is best for a small business in Cardiff?

Instagram for consumer categories and the big-weekend visitor trade, Facebook for the family suburbs, where it remains genuinely strong. LinkedIn carries government, media and professional services.

How do local businesses get customers from Instagram in Cardiff?

With local-first content that respects the city's identity, and match-day content planned ahead. A genuine Welsh touch where it fits earns warmth; preparation for the fixture list earns the biggest tills of the year.
