Social media marketing
What does a social media marketing agency do?
A social media marketing agency plans, creates and publishes content, looks after your community, runs paid campaigns and reports on what turns into enquiries and sales.
ProntX is a social media marketing agency in London for UK brands that want social to produce customers, not just likes. We handle strategy, content, community management, paid social, creators and reporting as one joined-up service, from £650 a month on a rolling plan.
Most businesses we speak to are in one of two places. Some post regularly but cannot tell whether it does anything: the content looks fine, the follower count creeps up, and nobody can point to a sale it produced. Others know social matters but cannot find the time, so accounts go quiet for weeks and then burst back with a run of rushed posts.
Both problems come from treating social as a posting schedule rather than a marketing channel with a goal, an audience and a way to measure results.
Our social media marketing services start with the goal. That might be bookings for a clinic, footfall for a restaurant, online sales for a skincare brand or demo requests for a software company. Content, community and paid campaigns are then planned around that goal, and measured against it.
Because ProntX also builds websites and runs search and email, social does not sit in a silo. A campaign can drive people to a landing page we built, into an email flow we wrote, and be measured in the same analytics.
What is included
What is included in our social media marketing services?
Five connected pieces of work, scaled to your package: organic content, community management, paid social, creator and UGC content, and reporting.
Organic
Content and publishing
A monthly content plan built around content pillars, then the posts themselves: short-form video, carousels, graphics, captions and stories, written in your brand voice and scheduled at the times your audience is active.
Community
Community management
Replies to comments and direct messages within agreed hours, moderation of spam and abuse, and escalation of complaints or sales enquiries to the right person on your team. Response times are agreed in writing.
Paid
Paid social campaigns
Meta, TikTok, LinkedIn and Pinterest ads with proper pixel and Conversions API tracking. Learn more about our paid social service and how we test creative.
Creators
Creators and UGC
Briefing and managing creators for user-generated style videos, product seeding and reviews, with clear usage rights so the content can also run as ads.
Strategy
Social media marketing strategy
Audience research, competitor review, platform choice and content pillars, refreshed every quarter based on what the data shows rather than on trends alone.
Reporting
Monthly reporting
Reach, engagement, follower growth and, more importantly, clicks, leads and sales tracked through UTM links and GA4. Each report ends with what we will change next month.
Platform choice
Which social platforms should your business be on?
The ones your customers use and that suit the content you can realistically make. For most businesses that means two or three platforms done well, not six done badly.
Instagram and Facebook
Still the default for most consumer brands, local businesses and hospitality. Reels, carousels and stories carry organic reach, and Meta ads offer the most mature targeting and catalogue tools.
TikTok
Strong for reaching younger audiences and for products that are easy to demonstrate. It rewards native, quick, human content over polished brand videos, which suits creator-led work.
Underrated for home, fashion, food, weddings and gifting, where people plan purchases weeks ahead. Pins keep sending traffic long after they are published.
The main platform for B2B, professional services and recruitment. Founder and employee profiles often outperform the company page. Our B2B social media service covers LinkedIn in depth.
YouTube Shorts
A useful second home for vertical video you are already making for TikTok and Reels, with the bonus of appearing in Google results.
How we decide
We look at where your existing customers and competitors are active, what content you can produce consistently, and where paid support is affordable. Then we recommend a mix and explain what we are leaving out and why.
How we work
How do we plan social content that actually sells?
We plan content in monthly cycles around a small number of themes, test hooks and formats deliberately, and feed what works into paid campaigns.
Content pillars tied to buying questions
Each brand gets three to five content pillars, built from the questions customers ask before they buy. For a skincare brand that might be ingredients explained, routines, before and after stories, behind the scenes and offers. For a dental practice it could be treatment explainers, meet the team, patient questions and local community. Every post belongs to a pillar, so the feed stays focused and nothing is posted just to fill a gap.
Hooks and formats tested on purpose
The first second of a video and the first line of a caption decide whether anyone sees the rest. We write several hooks for important posts, try different formats (talking head, product demo, carousel, text-on-screen) and track which ones hold attention. Over a few months, that builds a clear picture of what your audience responds to.
Organic winners become ads
Posts that perform well organically are strong candidates for paid promotion, because they have already proven they can hold attention. We move them into paid campaigns with proper targeting, which is cheaper and faster than producing ads from scratch.
Creators and user-generated content
People trust people more than brands. For many consumer businesses, we brief creators to make honest, unpolished videos using your product or service. We handle the brief, the shortlist, contracts, usage rights and feedback rounds, so the content can be used on your own channels and in ads without legal surprises. We choose creators for fit with your audience, not follower count alone.

What is includedWho it is for
Social media marketing for small business and growing brands
We work with London and UK businesses that have a clear offer and want social to support sales, from independent shops and clinics to ecommerce brands and B2B firms.
For a small business, the risk is spreading too thin. The Starter package is designed to do a few things properly: a consistent presence on the two platforms that matter, quick replies to messages, and a monthly look at what brought people through the door. Many small businesses get more from that than from posting everywhere. Our small business marketing page shows how social fits alongside search and a website on a modest budget.
For ecommerce and consumer brands, social is usually a mix of organic content, creator videos and paid campaigns working together, with results judged on sales.
- Independent retailers and ecommerce brands
- Beauty, skincare and wellness businesses
- Restaurants, cafes and hospitality
- Clinics, dentists and aesthetics practices
- B2B companies and professional services
- Property, interiors and home improvement
Social platforms can change their algorithms overnight. We build sign-up offers into your social plan and connect them to email marketing, so the audience you grow on social also becomes customers you can reach directly.

FAQ
Social media marketing questions, answered
Still unsure? Ask us anything. We reply within one working day.
How much does a social media marketing agency cost in London?
Our social media marketing packages start at £650 a month plus VAT for two platforms with content and community management. Growth packages typically run from £1,100 to £1,600 and larger programmes from £2,000. Ad spend for paid social is separate and paid directly to the platform. Final price depends on platforms and content volume.
Do you create the content or do I need to supply it?
We create it. That includes planning, copywriting, graphics, carousels and editing short-form video. The best results usually come from mixing our content with real footage from your business, so we often ask for quick phone clips or arrange a filming day. Creator and UGC videos can be added on Growth and Scale packages.
Which platforms do you manage?
We manage Instagram, Facebook, TikTok, LinkedIn, Pinterest, YouTube Shorts and Threads. We will recommend the two or three that suit your customers and content, rather than trying to cover everything. Adding a platform is possible on any package, and we explain the extra work involved before you decide.
How long does social media marketing take to work?
Content can be live within two to three weeks of starting. Organic growth builds over months, while paid social can bring traffic and sales within days of launch. By month three you should see clear trends in reach, engagement and, most importantly, the clicks and enquiries social is producing.
Will I approve posts before they go live?
Yes. Every post sits in a shared content calendar where you can approve it, comment or ask for changes. We agree a monthly rhythm, usually planning a month ahead, so approvals take minutes rather than hours. Reactive posts and community replies follow tone guidelines we agree with you at the start.
Do you handle comments and direct messages?
Yes, community management is included in every package. We reply to comments and messages within agreed hours, hide spam, and pass complaints or sales enquiries to the right person on your team with the full context. Out-of-hours cover can be added if your business needs it.
Are your packages suitable for a small business?
Yes. The Starter package was designed for small businesses that need a consistent, professional presence on the platforms that matter most, without paying for content they will not use. It focuses on two platforms, quick replies and clear monthly reporting on what drives enquiries.
Is there a minimum contract?
No. Our social media marketing services run on rolling monthly terms. You can change package or stop with notice. Your social accounts, ad accounts and the content we create for you remain yours, and we hand over the content library and brand guidelines if you leave.
How do you measure social media results?
We track reach, engagement and follower growth, but we put more weight on clicks, leads and sales. Every link uses UTM parameters so traffic and conversions show up in GA4, and paid campaigns use the Meta pixel and Conversions API. Reports explain what changed and what we will do next.
