Social recruiting strategy for SMEs: platforms, staff shares, UK rules and metrics

What to take away

Match the platform to the vacancy

Begin with the job, the pay, the hours and the location, because those four facts decide where candidates already spend their time. A warehouse role in a town with an active Facebook group rarely needs LinkedIn. A part-qualified accountant rarely turns up in a local community group. Write the facts down before you choose a channel, then choose the one that matches them.

Hardware shops, care providers and hospitality businesses often get their best returns from Facebook groups with a tight radius. Professional services firms get more from LinkedIn search and direct messages to people with the right job titles. One person should own the replies for each vacancy, because a slow answer loses a good candidate.

Give staff something worth sharing

Employee advocacy works because a share from a real colleague reads as a recommendation rather than an advert. Ask four or five people who already talk about work positively, give them the wording and the image, and let them edit it. Put the arrangement in writing, including what happens when someone leaves. The guide to employee advocacy for employer branding explains how to keep the scheme voluntary and proportionate.

Set a small monthly budget

The figures below are a worked example for one SME hiring three roles at once, not a market average. Separate the money you spend on reach from the time you spend on replies, because the replies are what convert an application into a hire.

Spend in short bursts around each live vacancy. A low-level campaign running all year rarely fills a role. If £400 is beyond reach, cut the video line before the paid reach, since reach is what puts the vacancy in front of strangers.

Keep adverts inside UK recruitment rules

Job adverts, targeting settings and shortlisting decisions must not discriminate on protected characteristics. The Equality Act 2010 sets out those characteristics and the narrow exceptions for genuine occupational requirements.

Promoted posts must be obviously identifiable as marketing communications. The CAP code covers this under recognition of marketing communications, so label a paid job post as an advert rather than writing it to look like a friend's update.

Applications that arrive by direct message still count as personal data. Move them into one system, keep only what you need, and tell candidates how long you keep it, as the ICO guidance on UK GDPR explains.

Track four numbers, not forty

Watch reach, saves, applications and interviews offered. Reach tells you whether the post is being seen. Saves and shares tell you whether the offer is interesting. Applications and interview offers tell you whether the advert is honest about the job. The recruitment marketing metrics guide lists the definitions worth agreeing with your hiring managers. Agree the review date before the campaign starts, so nobody keeps a channel alive out of habit.

Common questions

How often should a small employer post?

Two or three times a week per vacancy is enough when each post carries a different detail, such as the shift pattern, the training or a line from the manager. Reposting the same wording daily annoys followers and rarely adds applications.

Do we need a paid budget to recruit on social media?

No, but paid reach helps when the local audience is small. Without a budget, put the time into replies and into asking staff to share instead.

Can we ask employees to share job adverts?

Yes, if sharing is voluntary, the wording is accurate and the consent is recorded. Never make it a condition of employment, and never edit a colleague's post without asking.
