How to build a social media marketing strategy
Key takeaway
A social media marketing strategy is a written plan that sets one measurable business goal, defines the audience, picks one to three platforms, sets a content mix and budget, and measures results in tools such as GA4, reviewed every quarter.
A social media marketing strategy is a written plan that says what social media must do for your business, who you are trying to reach, which one to three platforms you will use, what you will post and how often, and which numbers prove it is working. For most UK small businesses it fits on one page and is reviewed every quarter.
Most guides on this topic list ten generic steps and stop there. This one is written for UK businesses with a small team. It adds the parts those guides tend to skip: how people in the UK now use social platforms to search, the advertising rules you have to follow when you pay creators, and how to tag your links so Google Analytics shows which posts actually bring enquiries.
Key takeaways
- Start from one business goal and work backwards to platforms and content, not the other way round.
- Pick one to three platforms you can run properly. A neglected account does more harm than no account.
- Treat social as a search channel too: Ofcom found 43% of UK online adults search on social media platforms daily.
- Paid creator posts must be labelled clearly as ads under UK advertising rules, and the brand shares responsibility.
- Tag every link with UTM parameters so GA4 shows enquiries and sales from social, not just likes.
What is a social media marketing strategy?
A social media marketing strategy is the set of decisions behind your social activity: the goal, the audience, the platforms, the content mix, the budget and the measures. The posts are the output. The strategy is what makes those posts add up to more enquiries or sales rather than activity for its own sake.
It helps to separate three documents that often get mixed up:
- Strategy: why you are on social media, for whom, where, and how you will judge success. Changes a few times a year.
- Content plan: the themes, formats and series you will run this quarter to deliver the strategy.
- Calendar: what goes live on which day. Changes every week.
If you only have a calendar, you have a schedule without a reason. That is the most common situation we see when a business first asks ProntX to look after its social media.
How do you build a social media marketing strategy step by step?
You build a social media marketing strategy by setting one measurable goal, defining the audience, auditing what you already have, choosing platforms, deciding a content mix, setting a budget and agreeing how you will measure it. The seven steps below are the order we use.
- Set one primary goal tied to revenue. Examples: 20 quote requests a month from social, or 10% of online sales from social traffic. Brand awareness can be a secondary goal, but it should not be the only one.
- Describe the audience in plain words. Who buys, what they are trying to solve, what makes them hesitate, and where they already spend time online. Two or three short descriptions are enough.
- Audit your current accounts. List every profile you own, who has the login, when it last posted, and which posts drove clicks in the last 90 days. Close or archive accounts you will not run.
- Choose one to three platforms. Use the decision table below. Depth on one platform beats a thin presence on five.
- Decide the content mix. Pick three or four recurring content pillars (for example: how-to tips, behind the scenes, customer questions answered, offers) and the formats each one suits.
- Set the budget and resourcing. Decide who creates, who approves and who replies to comments, plus any paid budget to promote your best posts.
- Agree the measures and review dates. Choose two or three numbers linked to the goal, tag your links, and book a monthly check and a quarterly review in the diary now.
Which social media platforms should a UK business use?
Use the platforms where your buyers already make decisions, and only as many as you can post to and reply on consistently. The table below is a starting point based on what each platform is built for, not a rule.
| Platform | Usually suits | Content that tends to fit | Main goal it serves well |
|---|---|---|---|
| Local services, trades, hospitality, community-led businesses | Updates, offers, reviews, local groups, events | Enquiries and repeat custom | |
| Visual products, beauty, food, retail, ecommerce | Reels, carousels, Stories, product shots | Discovery and online sales | |
| TikTok | Brands with a younger audience or a product that demonstrates well | Short vertical video, tutorials, trends | Reach and discovery |
| B2B, professional services, recruitment | Founder and staff posts, insights, case write-ups | Leads and credibility | |
| YouTube | Anything that needs explaining or demonstrating | How-to videos, product walkthroughs, Shorts | Search visibility and trust |
| Home, interiors, weddings, crafts, fashion | Pins linking to products or guides | Website traffic |
A quick test before you commit to a platform: can you name three competitors or businesses your customers follow there, and can you produce at least two good posts a week for it without slipping? If the answer to either is no, leave it for now.
Why does social search matter for your strategy?
Social search matters because many UK adults now use social platforms to look things up, not just to scroll. Ofcom’s Adults’ Media Use and Attitudes report (published May 2025) found that 43% of UK online adults say they use social media platforms such as Facebook to search at least once a day, and 34% use video-sharing platforms such as TikTok to search daily.
The same research found a trust gap. Around 59% of people said they always or mostly trust information from search engines, compared with 19% for social media platforms. In practice this means two things for your strategy:
- Write posts and profiles that can be found. Use the words customers search for in captions, video titles, on-screen text and your bio. “Boiler service in Croydon: what is included” is easier to find than “Busy week for the team”.
- Give people a trusted place to check you. Social often starts the journey, but buyers verify on your website and in Google. Link posts to useful pages, and make sure your website answers the questions your posts raise. Our guide to planning website content around search covers that side.
What should you post on social media?
Post content that answers your buyers’ questions, shows your work and gives them a reason to act, in roughly that order of priority. Constant selling gets ignored; constant entertainment rarely brings enquiries.
Ofcom’s research also found that people are more sceptical online than they think they are. When shown a celebrity paid partnership post, 76% of online adults correctly said it was at least partly paid for, but 16 to 24 year olds were the least likely to spot it. Honest, useful content with a clear point of view holds up better with a wary audience than polished adverts dressed as posts.
A content mix that works for many small businesses:
- Answers: short posts or videos replying to questions customers ask on the phone or in email.
- Proof: before and after photos, finished projects, reviews shared with permission.
- People: who does the work, how you do it, what happens when someone books.
- Offers and calls to action: a clear next step, used sparingly, linked to a page built for it.
Repurpose rather than starting from scratch. One customer question can become a short video, a carousel, a LinkedIn post and a section on your website.
What UK advertising rules apply to social media marketing?
If you pay or reward someone to post about your business, or you control what they say, that post is an ad and must be clearly labelled as one. The rules are set out in the CAP Code, applied by the Advertising Standards Authority (ASA), with guidance written jointly with the Competition and Markets Authority.
According to the ASA’s guidance on recognising ads on social media, the key points are:
- Payment, free products or other incentives, affiliate links and discount codes can all make creator content an ad.
- Labels such as “Ad”, “Advert” or “Advertising” (with or without a #) are very likely acceptable. “Sponsored”, “Gifted”, “In association with” and abbreviations such as “spon” or “aff” are not recommended.
- The label should be prominent and visible before someone clicks, expands or engages, usually at the start of the caption or video.
- Platform paid-partnership tools may help but may not be enough on their own if the label is hard to see.
- Brands and creators can both be named in an ASA ruling, so build labelling into your creator agreements and check posts when they go live.
The ASA notes its influencer guidance will be updated following the Digital Markets, Competition and Consumers Act 2024, so check the current version before you brief creators.
How do you measure a social media strategy?
Measure a social media strategy against the goal you set, using website and sales data, not just platform likes. Platform insights show reach and engagement; GA4 and your enquiry records show whether social produced business.
The simplest reliable method is to tag every link you post with UTM parameters. Google’s Analytics Help says you should always use utm_source, utm_medium and utm_campaign, that values are case sensitive, and that campaign traffic appears in the Traffic acquisition report. A tagged link looks like this: yoursite.co.uk/offer/?utm_source=instagram&utm_medium=social&utm_campaign=spring_offer. Keep values lowercase and agree a naming convention so “Instagram” and “instagram” do not split your reports.
Which numbers to track depends on the goal:
- Enquiries: form submissions and calls from social traffic, cost per enquiry if you run ads.
- Online sales: revenue and orders from social sessions in GA4 or your shop platform.
- Awareness: reach, follower growth from your target area or sector, and branded searches over time.
- Health checks: response time to comments and messages, and how many posts went out against plan.
Should you use paid social as part of the strategy?
Paid social belongs in the strategy when organic reach is too small to hit your goal in a sensible time, which is common for new or local accounts. It works best on posts already proven to get a response organically.
A practical approach is to start small: put a modest test budget behind your two best performing posts, send the clicks to a page built for that offer, and compare cost per enquiry with your other channels after four to six weeks. If you want help running ads on Meta, TikTok or LinkedIn, see how we handle paid social campaigns.
A one-page social media strategy checklist
Use this checklist to test whether your strategy is complete. If you cannot tick an item, that is the gap to fix first.
- One primary goal with a number and a date.
- Two or three plain-English audience descriptions.
- A list of every account you own, with logins held by the business, not a former employee or supplier.
- One to three chosen platforms, with a reason for each.
- Three or four content pillars and the formats for each.
- A named person for creating, approving and replying, and a reply-time target.
- A paid budget, even if it is zero for now.
- A UTM naming convention and a GA4 report you check monthly.
- Ad labelling rules written into any creator or influencer brief.
- A quarterly review date in the diary.
How much does it cost to run a social media strategy?
The cost is mostly time if you run it in-house, plus any ad spend. Writing the strategy itself might take a day; running it well usually means several hours a week for content, replies and reporting.
If you would rather hand it over, ProntX social media marketing starts from £650 a month on a rolling monthly contract, with ad spend paid directly to the platform and the accounts staying in your name. Smaller businesses can also look at our social media packages for small firms.
