Social media marketing for a small business: what to post, where, and how often

Use the platform where your customers already are, and choose by their age and by what you sell. In the US, 84% of adults use YouTube and 71% use Facebook, while Instagram is used by 80% of under-30s and 19% of over-65s (Pew Research Center). For local services that means Facebook or Instagram first; for firms selling to firms, LinkedIn.

The totals hide the part that decides it. Facebook is used by 74% of Americans aged 50 to 64 and 57% of over-65s; TikTok by 63% of 18- to 29-year-olds and 12% of over-65s. Pick by your customers' age, then stay on one platform until it has run on schedule for three months. Two accounts updated in bursts look closed to a stranger. One account with a post every other day looks open.

In the EU, 60.59% of enterprises with 10 to 49 staff used any social media in 2025, against 89.09% of those with 250 or more (Eurostat). Four small firms in ten had no social media presence at all.

One detour. Before any social account, I would have a local business fill in its Google Business Profile, the listing that shows in Google Maps and beside the map in Search, with its own photographs, hours and posts. Our Google Business Profile guide covers the setup.

Post the work itself: finished jobs, before-and-after photographs, short vertical videos of something being made or fixed, and straight answers to the questions customers ask on the phone, prices included. A post like that shows someone who has never heard of you what buying from you looks like, and a recommendation is how it reaches them.

Format decides how far a post travels. Buffer's analysis of more than 45 million posts, published in March 2026, found Instagram reels reached 2.25 times as many people as single photographs, and carousels got the largest share of viewers to react (Buffer). Instagram's own explainer says Reels ranking predicts whether you will reshare a reel and watch it to the end (Instagram). YouTube takes Shorts of up to three minutes (YouTube Help); I aim for 15 to 30 seconds, a haircut start to finish or a leaking tap before and after.

Your customers write the content plan every time they ring. For two weeks, write down every question they ask: the price, how long it takes, whether you work Saturdays. Each one is a post. An answer with a price in it gives people a reason to save it or send it to whoever they decide with.

Before-and-after photographs are the strongest material a clinic, salon or builder has. On the website we rebuilt for Amir Hair Clinic, a Sofia practice treating hair loss, real before-and-after photographs have a results page to themselves, and I would plan a clinic's feed on the same material: one pair per post, with the treatment named. Post a photograph in which a client can be recognised only with their consent. Get it in writing. Under Article 7 of the GDPR, which the UK kept in its own law, you must be able to prove that consent, and the client can withdraw it at any time.

Three posts a week on one platform, every week, is the rhythm I recommend to a small business. Buffer's study of more than 2 million Instagram posts found accounts posting three to five times a week grew followers more than twice as fast as accounts posting once or twice, with about 12% more reach per post (Buffer).

On TikTok, Buffer's analysis of 11.4 million posts found two to five posts a week brought 17% more views per post than one, and six to ten brought 29%, for twice the work (Buffer).

Treat three posts a week as a starting schedule, then adjust it to the material you can produce and the response it gets. In the cited TikTok study, higher frequency increased the chance of a high-performing post, while median views were similar. Frequency alone does not establish quality.

Meta Business Suite, Meta's free tool for Facebook and Instagram, schedules posts from 20 minutes to 29 days ahead, lays them out on a Planner calendar and has an Active times button that suggests when your audience is most active (Meta). Take the photographs as each job finishes, then write and schedule the week's three posts in one sitting.

Prepare the photographs and draft posts ahead of publication so there is time to review them.

Facebook and Instagram decide what each follower sees, and a business's post competes with everything that person's friends, groups and followed Pages have shared. Facebook's Feed system gathers those posts, shortlists about 500 and ranks them by how valuable it predicts each will be, using signals such as how that person has reacted to the poster before (Meta).

The averages are low. Socialinsider put the average Facebook post at 0.15% engagement against followers in 2025, across 25 million posts: three reactions, comments or shares for a Page with 2,000 followers. Instagram averaged 0.48% (Socialinsider). Facebook posts with a link did worst, at 0.05%, and in Meta's report only 1.1% of US Feed views were of posts linking out of Facebook. The same report holds the number that favours a small business: recommendations fill 36.6% of the Feed, and Instagram wrote in 2023 that in Reels “the majority of what you see is from accounts you don't follow” (Instagram). Recommendations are how a good post from an account with 300 followers reaches people who have never heard of the business.

So I keep links out of most posts. The price goes in the caption, the call to action is “message us”, and the link sits on the profile.

Boosting a post is worth the money when the post already worked without any. A boost turns an existing post into an ad and shows it to more people, chosen by age, gender and interests, with a goal such as more messages or more website visitors (Meta). Boosting a post nobody reacted to buys the same indifference in bulk.

My starting test: take the post from the last fortnight that brought the most messages and boost it for seven days at €5 to €10 a day, with the goal set to messages. Then count the conversations. If they arrive at a price a job can carry, repeat with the next good post. If the week brings likes and no messages, stop, and change the post before you change the budget.

Boost from a computer or a phone's browser, not from the Facebook or Instagram app on an iPhone or iPad, where Meta says Apple keeps a 30% service fee on the payment (Meta on the Facebook app, on the Instagram app). A before-and-after for a cosmetic treatment can be boosted if the ad is aimed at people aged 18 or over and says nothing negative about anyone's appearance, under Meta's health and wellness advertising standard.

Meta's comparison leaves leads and sales to Ads Manager, beyond what a boost can aim for. Once boosting becomes a monthly budget, it needs an ads account with tracking, which is the Meta and Google ads work we do. Facebook and Instagram ads for a small business covers budgets and the first month.

Count what turns into money: conversations that ask about price or availability, calls, visits to your website from your posts, and customers who say they found you on Instagram or Facebook. Likes and followers go at the bottom of the report. Six likes and two bookings did more work than forty likes and none.

The conversations only count if somebody answers them. Meta shows a “very responsive” badge on a Page that answers at least 90% of its messages with a response time under 15 minutes, and away messages and instant replies count towards neither figure (Meta), so an automatic “thanks, we'll be in touch” does not earn it. Replying to comments pays too: across nearly 2 million posts, Buffer found that posts where the account replied got 21% more engagement on Instagram, 9% more on Facebook and 30% more on LinkedIn. Meta Business Suite gathers messages and comments from Facebook, Instagram and WhatsApp Business into one inbox. Whoever holds that inbox is doing sales, whatever their job title says.

For website visits, tag every link you post with utm_source, utm_medium and utm_campaign, as Google Analytics asks (Google), and read the visits by platform in its Traffic acquisition report. A profile link becomes example.com/?utm_source=instagram&utm_medium=social&utm_campaign=profile.

At the end of each month, write down four numbers per platform: conversations about buying, calls, tagged website visits, and sales you can trace back, which means asking “where did you find us?” on the phone and at the till. Three months of them say more than any dashboard.

Run in-house, social media marketing costs a small business time: I would budget three to four hours a week for three posts and the replies. As a paid service, it runs from about £250 (€290) a month for basic support to £3,000 (€3,490) and more for a full service with video, in a guide to outsourcing that a UK agency published in August 2026. US figures run from $400 to $5,000 (€340 to €4,290). Ad budgets come on top.

• Doing it yourself: the hours above, a decent phone camera and Meta Business Suite. Cheapest in money, the first to slip when the business gets busy.
• One person on the work costs from about £300 (€350) a month in the UK, and £800 to £2,000 (€930 to €2,330) with experience behind it, the same guide says. In the US, SocialPilot prices one person running two channels at $400 to $2,000 (€340 to €1,720).
• Everything handed over, month by month: UK retainers from around £1,500 (€1,750) in that guide, while another UK price list's entry package is £350 to £550 (€410 to €640) for four to eight posts plus light SEO work. A US agency's own pricing page gives $500 to $5,000 (€430 to €4,290) a month as the average for social media management.
• Employing a social media manager in England costs £25,000 to £50,000 (€29,100 to €58,200) a year before employer costs, says the National Careers Service.

Prices checked 10 September 2026; euros at the European Central Bank's rate for 9 September.

Keep the replies, whatever else you hand over: only you know whether Thursday at four is free.

The photographs stay with you, because you are there as the job finishes. Captions, video editing and the ads around the posts that already brought messages are work we take on. Hand them over when the posting stops. If the last three months have two-week gaps, the problem is time. Money solves that. If the posts went out on schedule and nothing came back, the problem is the posts or the offer, and more of the same will not move the four numbers.

At three posts a week, a month is twelve posts: four of finished work, three answering customer questions, two short videos, two from behind the scenes and one offer with an end date. Plan them in one sitting and, in week three, boost whichever of the first six brought the most messages.

1. Week one: Monday, a finished job before and after; Wednesday, last month's most-asked question, answered with the price; Friday, a 20-second video of a job in progress.
2. Week two: another finished job, then behind the scenes, then the second question.
3. Week three: finished work, the second video, and on Friday the offer with the date it ends. The boost runs Monday to Sunday.
4. Week four: finished work, the third question, behind the scenes again. On the last day, the four numbers go in the sheet.
