If you have £500 a month and a local service business, Meta ads can work. They just do not work the way most agencies run them. The usual playbook of four campaigns, ten audiences and twenty creatives is a budget-burner built for accounts spending twenty times that. Small budgets need the opposite: radical focus on one audience, one creative and one conversion event.
This post is what we actually set up for a local plumber, a tutoring business and a dental practice, in the same shape every time, on that same £500 monthly cap.
Start with one audience
Draw a ten-mile radius around your office, shop or service area. Layer on age and one interest only if the category genuinely needs it. Do not fragment the audience into five versions of itself. Meta's algorithm learns faster when you feed it one clear signal, and you will see results in two weeks rather than two months.
Skip lookalikes and custom audiences on month one. They get interesting once you have a conversion base of at least 50 leads. Until then, cold interest-based or broad targeting with tight geography wins.
Start with one creative
A thirty-second vertical video of the owner saying what they do and why. Phone-camera quality is fine. Subtitles are not optional, 80% of Meta views happen on mute. End with a clear ask: "book a free quote", "message us on WhatsApp", "call for same-day availability".
The owner's face wins here for two reasons. One, it beats the "stock video" smell test that kills small-business ads. Two, it shortcuts the trust question. Prospects have seen who they will be dealing with before they click.
Start with one landing page
Send clicks to a dedicated landing page, not your homepage. One job per page: get the visitor to take one action. Strip navigation. Put a WhatsApp button as the fallback for people who will not fill a form. Track the form submit and the WhatsApp click as two separate conversion events in Meta Pixel.
If you do not have a landing page yet, build a single long page in Astro or your existing CMS. Keep it under 1.5 seconds to first paint on mobile, or your click-through spend becomes bounce spend.
Budget split that holds up
We split £500 per month like this:
- £350 on the top creative. This is your workhorse. Do not touch it unless cost per lead breaks.
- £100 testing one new variant per week. Same audience, different hook or opener. Rotate variants in, kill losers on cost per 1,000 impressions, promote winners to the £350 bucket.
- £50 retargeting. People who visited the landing page but did not convert. Different creative here, something with social proof: a testimonial, a before-and-after, a specific stat.
At week four you have a working baseline. At week eight you start layering.
The only four numbers that matter
Ignore likes, shares, reach, video completion rate. Track these four in a simple monthly spreadsheet:
- Cost per qualified conversation. Not per click. Not per lead. Per qualified lead, the ones your team wants to call back.
- Close rate on that lead source. Are Meta-sourced leads worse than word-of-mouth? If yes, your creative or landing page is wrong.
- Customer lifetime value from Meta clients. Track six months out. Sometimes Meta leads have a lower first-sale but a better repeat rate.
- Payback period. How many weeks until the ad spend is earned back from that client. For most small service businesses, anything under eight weeks is green.
If the numbers work, scale the budget by 25% a month until the cost per qualified conversation moves by more than 30%. When it does, stop scaling and optimise creative again.
What to skip
Do not buy "managed Meta ads" at £1,500 per month to run £500 of spend. The agency fee eats the budget before the audience sees anything. If you cannot run these yourself, pay a freelancer a flat £300 to set it up and show you how to manage week-to-week.
Do not run until you have a landing page that converts cold traffic at 2% or better. Ads amplify whatever is there. A 0.5% landing page at £500 of spend produces one client and a lot of regret.
Do not set up "brand awareness" campaigns. For a small local service business, every ad is a direct response ad. If Meta cannot attribute a form submission or a WhatsApp click to it, cut it.
A realistic first-month outcome
On a £500 budget, expect 12 to 25 qualified conversations. Expect 3 to 7 of those to convert into paying clients at an average ticket of £400 to £1,200. You are not aiming for scale yet, you are aiming for a repeatable cost per client so you can decide whether to push to £1,000 per month next quarter.
Meta ads for small businesses are not magic. They are a disciplined routine of one audience, one creative, one landing page, one metric. Run that routine for ninety days and you will know exactly what your client-acquisition cost is. Most small business owners have never had that number.
