Why Use Social Media for Business: Making the Investment Case

Most business owners do not ask whether social media exists. They ask whether it is worth the time, money and attention it demands. That is a fair question, and it deserves a straight answer rather than a list of follower counts. The reasons to use social media for a business come down to three things: it puts your brand in front of people who are already deciding where to spend,

it costs less per contact than almost any traditional channel, and it gives you a direct line to your customers. This guide weighs up those benefits against the real costs, looks at which platforms earn their place, and shows how to measure whether your social media activity is actually paying off.

Why Use Social Media to Promote Your Business

The short answer to “why use social media for marketing” is that buyer behaviour has shifted, and the channel follows the audience. People research products, read reviews and form opinions about companies on social platforms before they ever visit a website or pick up the phone. A business that is absent from those conversations is simply harder to find and harder to trust. The purpose of social media for a company is not vanity; it is reach, reputation and a route to the sale.

“Social media success isn’t about follower counts or viral posts,” says Ciaran Connolly, founder of ProfileTree. “It’s about building genuine connections with your audience and giving them something useful at every step. The businesses that get results treat social media as a relationship-building tool, not just a broadcast channel, and they connect it to their website and SEO rather than running it in isolation.”

The benefits below are the practical reasons for using social media that hold up once the novelty wears off.

Brand awareness

Consistent posting keeps your business visible to people who are not yet ready to buy but will be later. When a prospect finally needs it, the brand they already recognise has a head start. This is where social media interaction quietly does its work, turning a stranger into someone who knows your name. For a fuller view of how those touchpoints add up, the ProfileTree breakdown of social media interactions is a useful companion.

Brand loyalty

Businesses that show up regularly and respond to their audience tend to hold on to customers for longer. Being reachable with a single message or comment removes friction from the relationship. That accessibility is one of the quieter reasons to use social media, and it costs nothing but attention.

Cost efficiency

When people ask why social media should be used for marketing, cost is usually the first honest answer. Setting up a business profile on any platform is free. Paid promotion exists, but even paid social sits well below the per-contact cost of television, radio or billboards. For a small business in Belfast or anywhere across Northern Ireland, that difference decides whether a campaign is affordable at all.

Boosting your site’s SEO

Social media is not a direct Google ranking factor, and any guide that claims otherwise is overselling. What it does do is drive brand searches, referral traffic and the kind of visibility that earns links, all of which support search performance over time. Used alongside a proper SEO programme, social becomes a distribution channel for content that is built to rank. The two work best together, which is the thinking behind connecting your social posting to your wider content plan.

A higher conversion rate

A conversion is any action you want a visitor to take, whether that is a sale, an enquiry or a sign-up. Social media feeds the top of that journey: a post earns a profile visit, the profile earns a click to your website, and the website earns the enquiry. The weak link is usually the website. Traffic arriving from Instagram or Facebook lands on a page that loads slowly or buries the next step, and the click is wasted. This is the practical overlap between social media and website design: the social activity creates demand, and the site has to be ready to convert it.

The humanisation element and customer interaction

People prefer dealing with people rather than faceless companies. Replying to a comment or resolving a complaint in public shows prospective customers that the business is attentive. Above all, social media is a communication platform, and the value of two-way contact is hard to replicate elsewhere. This is also why social media engagement is important: each genuine exchange tells your audience there is a person behind the brand, and it gives you direct insight into what customers actually want.

The Real Costs and How to Weigh Them

The honest version of the business case includes the costs, not just the upside. Social media is cheap to start and expensive to do well, because the real cost is time. Before committing, weigh up four things: the staff hours needed to create and schedule content, any paid advertising budget, the cost of management or scheduling tools, and the cost of producing decent creative, such as photography or video.

For most SMEs in Northern Ireland and Ireland, the question is rarely “can we afford to post” but “who is doing it and at what standard”. Patchy, low-effort posting can cost more in reputation than it returns in reach. If the in-house option is not realistic, the alternatives are bringing in a social media management partner or training the existing team to run it properly through digital training. Either way, the cost belongs in the calculation from the start.

Types of Social Media and What Each Is For

There are several types of social media, and each has a distinct purpose. Choosing the right ones matters more than being everywhere, because spreading a small team across six platforms usually means doing none of them well. The main categories are below, and a full directory sits in the ProfileTree guide to the major social media platforms.

Social networks

Networks such as Facebook and LinkedIn are the most common form of social media and the natural home for ongoing brand presence. They let customers follow your news, products and updates, which keeps you in regular contact with your audience. LinkedIn in particular rewards businesses that publish for a specific sector; the ProfileTree overview of LinkedIn industries shows how that plays out by trade.

Media sharing

Media-sharing platforms exist for images and video, and they reward businesses that can show rather than tell. Sharing a short video of your work or product is one of the cheapest ways to market a company, and the reactions you get are themselves useful market research. Video also carries further than static posts, which is why video marketing and social distribution tend to be planned together. The visual side of this is covered in depth in the ProfileTree piece on the role of visual content.

Blogging and owned content

Blogging is one of the older forms of social media, and it remains the foundation most other channels point back to. A business blog builds visibility through content marketing and gives your social accounts something worth sharing. Choosing where to publish it is a decision in itself, which is covered separately in the ProfileTree look at the best blogging platforms. Connecting that owned content to a content marketing plan is what turns occasional posts into a steady stream of material.

Online shopping platforms

Shopping platforms are both a sales channel and a feedback loop. Customer ratings and reviews tell you how products are received and where they can improve, which is information you would otherwise pay for.

Which Platforms Are Worth Your Time

Every platform claims to suit every business, which is rarely true. The practical question is where your specific audience already spends time, and which format you can realistically produce. The table below summarises the common fit for SMEs in the UK and Ireland.

If you are unsure which of these earns your attention, a digital strategy review will usually answer it faster than trial and error. You can also see what is gaining traction by checking platform activity with a social media search approach before you commit resources.

What Makes Good Social Media Content

Having accounts is not the same as getting results. Strategic, engaging content is what separates social media marketing that converts from posting for the sake of it. The formats that consistently perform are educational or entertaining videos, company news and announcements, employee and behind-the-scenes stories, polls and contests, responses to customer questions, and user-generated content such as reviews. The common thread is that each gives the audience a reason to stop, which is the real definition of engaging content in social media marketing. For a deeper treatment, the SME best practice guide and the marketing strategies overview both go further.

Make Data-Driven Decisions

Good social media is run on evidence, not instinct. Use platform analytics to find which posts actually earn engagement and traffic, then do more of what works while testing new formats against it. Free tools cover most of what a small business needs to start, as set out in the ProfileTree roundup of analytics tools. Learning to read that data is a skill any team can pick up, and it is a core part of structured digital training.

AI tools now handle a growing share of the routine work, from drafting captions to spotting trends, and they are changing how small teams keep pace. The ProfileTree piece on AI in marketing covers where it genuinely helps and where it does not.

Measuring Success and ROI

The whole investment case rests on whether you can measure a return. Successful businesses track both engagement and business outcomes, then tie them together. Match your metrics to your goal: reach and follower growth for awareness; likes, comments, click-through rates and profile visits for engagement; contact form submissions and enquiries for lead generation; and sales attributed to social, cost per lead and return on ad spend for conversion.

To track properly, you will need more than the built-in dashboards. Google Analytics 4 shows website traffic from social, UTM parameters tag individual campaigns, and a CRM links an enquiry back to the post that started it. A simple way to express the result is: social media revenue minus social media costs, divided by costs, multiplied by one hundred, giving an ROI percentage. The discipline of doing this monthly is what turns social media from a perceived cost into something you can defend in a budget meeting. Pages that consistently turn social activity into sales are worth studying, and the ProfileTree analysis of how social media sales are built is a good place to start.

The Future of Marketing

Traditional advertising on television, radio and billboards still works, but it reaches a shrinking share of attention at a rising cost. Social media is where audiences now spend their time, and it allows the kind of personalised, two-way contact that broadcast channels never could. The reach is real, but reach without measurement is just spending. According to Ofcom’s Online Nation research, online platforms now account for a substantial share of UK media time, which is why the channel keeps growing in commercial importance.

Conclusion

Social media earns its place in a marketing budget when it is treated as a business investment rather than a habit. The reasons to use it are reach, low cost per contact and direct customer relationships, but those only pay off when the activity connects to your website, your content and clear measurement. Decide which platforms suit your audience, produce content worth engaging with, and track the return. Done that way, the answer to why use social media stops being a guess.
