Free advertising for small businesses: 12 ways that work

Key takeaways

Free advertising for a small business means channels with no media cost: listings, social media, reviews, referrals and your own signs. They cost time, not money, and together they form the base that any paid advert later relies on.

• 12 methods need no media spend.
• Time is the price: budget 3 to 5 hours a week.
• Listings and reviews pay back fastest.
• Add paid adverts once the free base is complete.

Is any advertising really free?

No advertising is free of effort. 'Free' here means you pay no media owner. At the April 2026 National Living Wage an hour of staff time costs about £16.27 with employer costs, so four hours a week is roughly £3,400 a year. That is still a low price for a base that lasts.

How do reviews and referrals count?

Reviews and referrals are advertising other people do for you.

• 7. Ask every satisfied customer for a review.
• 8. Ask for referrals and thank people who give them.
• 9. Swap recommendations with firms that serve the same customers.

• Word of mouth vs social media: can referrals be scaled?

What do you already own that can advertise?

Your own assets advertise every day once they carry your name clearly.

• 10. Email signature, invoices and quotes.
• 11. A job-site board, with the customer's permission.

Which should you do first?

Do the listing and the reviews first, because they help people who are already looking. Then set a weekly posting habit. Then work on referrals. Leave press stories and partnerships until the basics run without thought.

How much time should you set aside?

Set aside three to five hours a week and protect them. A workable split is one hour for listings and reviews, two for creating and posting content and one for replying and taking part in local groups. Put the hours in the diary as you would a job, because free methods fail mainly through neglect.

• Batch a month of social content in half a day

What are the limits of free advertising?

Free methods are slow and mostly reach people close to your existing customers. Unpaid posts are shown to a fraction of followers. If you need enquiries this month, or want to reach a new area, free methods alone will not do it.

When should you start paying?

Start paying when the free base is complete and you want growth you can control. Paid social has a practical floor of £300–£500 a month. If time is the constraint, most UK SMEs using an agency pay £950–£2,500 a month for managed social media.

What does this look like in practice?

A pattern we see with firms on tight budgets: money is found for an advert while the free listing has no photos and four reviews. An afternoon spent completing the free methods usually does more than the advert would have.
