This guide explains how Facebook and Instagram advertising works and how to set it up properly, in the order I would do it for a UK small business running its own ads for the first time. UK consent and advertising rules are built in at each step, because they change how the setup should be done. If you want a list to tick rather than an explanation, keep the Facebook and Instagram ads checklist open alongside it.
What Meta ads do well, and where they struggle
Meta ads put your message in front of people who were not looking for you. That is the big difference from search advertising. Someone typing “emergency plumber Croydon” into Google needs help right now; someone scrolling Instagram on the bus does not. Meta’s job is to work out who is likely to respond and interrupt them with something worth stopping for.
That makes it a good fit for:
- Products people discover visually or buy on impulse, such as clothing, beauty, homeware, food, gifts and event tickets.
- Offers with a clear reason to act now: a free first consultation, an opening price, a limited number of booking slots.
- Bringing back people who visited your site or engaged with your posts but did not buy.
It is weaker when the need is urgent and searched for (a locksmith, a boiler repair), when your buyers are a short list of named companies, or when the product cannot be understood in a few seconds of video. In those cases search ads usually carry the load and Meta plays a supporting role, if it plays one at all.
Set up ownership before anything else
Every Facebook Page, Instagram account, ad account and tracking dataset should sit inside a Meta business portfolio (the tool that used to be called Business Manager) owned by the business itself. A common problem is the opposite: an ad account created on a former employee’s personal profile, or everything built inside an agency’s portfolio, so that when the relationship ends the ad history and the tracking data leave with them.
The setup I recommend:
- Create the portfolio from the owner’s or a director’s own Facebook profile, using a business email address, and add a second trusted person as a full admin so that one locked profile cannot shut the business out.
- Switch on two-factor authentication for every admin. A hacked personal profile is an easy way to lose access to the ads.
- Connect the Facebook Page and the Instagram professional account to the portfolio, then create the ad account inside it with pounds sterling as the currency and London as the time zone. Changing either later is awkward, so set them correctly at the start.
- Complete business verification with official documents, such as your Companies House details and a utility bill or bank statement in the business name.
- Verify your website domain, which gives you control over how links to your site are shown in ads.
- Give agencies and freelancers partner access to the specific assets they need. Never hand over ownership.
Add your billing details in the business name and, if you are VAT-registered, your VAT number, so the invoices Meta issues are usable by your accountant.
Tracking: the Pixel, the Conversions API and UK consent
Meta can only learn who is likely to buy from you if it is told when someone does. Two pieces of tracking do that. The Meta Pixel is a script on your website that reports actions such as a page view, a form submission or a purchase from the visitor’s browser. The Conversions API sends the same events from your server or website platform straight to Meta, so they are less affected by ad blockers and browser privacy settings.
Run both, and give each event a shared ID so Meta counts an action once rather than twice. Shopify, WooCommerce and many booking and form tools have integrations that do this without custom code. Afterwards, open Events Manager and check that events arrive from both the browser and the server and are being deduplicated.
Choose events that mean money. For a shop that is a purchase, sent with its value. For a service business it is usually a lead, fired on the thank-you page after a real form submission, not when someone taps a “Contact us” button. Counting button taps as leads is one of the most common setup errors, and it trains Meta to find people who tap buttons.
Consent under PECR and UK GDPR
The pixel sets advertising cookies and reads information from the visitor’s device, so under the Privacy and Electronic Communications Regulations it needs consent before it runs. ICO guidance is clear that advertising cookies are not strictly necessary. In practice that means a cookie banner where rejecting is as easy as accepting, with the pixel blocked until the visitor accepts marketing cookies.
The Conversions API is not a way round this. Sending a customer’s hashed email address or phone number to Meta is still processing personal data under UK GDPR, so it needs a lawful basis, a clear mention in your privacy notice and respect for the choice the visitor made in your banner. Once consent is handled properly, Meta will record fewer conversions than really happen. That is expected, and it is one reason Ads Manager and your own sales records never quite agree.
Choosing the campaign objective
Ads Manager asks you to pick one of six objectives: Awareness, Traffic, Engagement, Leads, App promotion and Sales. Treat the objective as an instruction rather than a label, because Meta delivers precisely what you ask for. A Traffic campaign finds people who click links, and plenty of them leave before the page has loaded.
For most small businesses the real choice is between two:
- Sales, optimised for purchases, if you sell online and your tracking records purchases reliably.
- Leads, optimised for an enquiry on your own site or an instant form inside Facebook and Instagram, if you sell a service.
Awareness and Engagement have their uses, mainly for a local launch or for building an audience to retarget later, but do not judge them on enquiries, because they are not designed to produce any. Traffic is popular with first-time advertisers because the cost per click looks cheap; it rarely turns out to be the cheapest way to win a customer.
Conversion objectives come with a catch. Each new ad set goes through a learning phase while Meta works out who converts, and Meta’s long-standing guidance is that it needs around 50 of your chosen events in a week to finish. If your budget buys five leads a week, the ad set never settles and costs stay erratic. The usual fixes are to merge ad sets so that one gets all the data, or to optimise for an event that happens more often, such as a landing page view or an add to cart, until volume grows. The Delivery column in Ads Manager tells you whether an ad set is still learning or stuck at “Learning limited”.
Audiences: who actually sees your ads
Targeting on Meta has changed a great deal. Success used to depend on picking precise interests by hand. Since Apple’s tracking changes in 2021 and Meta’s own move towards automation, the delivery system does most of that work, and narrowing an audience manually often raises costs without improving results.
Broad and Advantage+ audiences
You set the location and a minimum age, perhaps add a few suggestions, and Meta looks for the people most likely to take the action you chose. With sound tracking and a budget that can feed the learning phase, this is usually where I start. It relies entirely on the conversion data, which is why tracking comes first in this guide.
Custom audiences
These are people who already know you: website visitors (only those who accepted cookies), people who engaged with your Facebook or Instagram, viewers of your videos, and customer lists you upload. Only upload a customer list when your privacy notice covers it and the people on it would reasonably expect to see your ads. Under UK GDPR, a single past purchase does not make every later use of someone’s email address fair.
Lookalike audiences
A lookalike audience asks Meta to find people who resemble a source list, ideally your best customers rather than every enquiry you have ever had. Lookalikes were once the backbone of most accounts. Now that broad targeting performs well, I treat them as one option to test, not a default.
Location for local businesses
You can target a radius around an address, a list of postcodes, a town or a region. A salon in Hackney has no use for impressions in Harrow, so draw the area around where customers really travel from, then check the estimated audience is big enough for your budget to spend without showing the same people the same ad every day.
Campaign structure and budget
A Meta account has three layers. The campaign holds the objective. The ad set holds the audience, placements, budget and schedule. The ads hold the creative. The structure problem I see most in small UK accounts is too many ad sets, each spending a few pounds a day and none of them collecting enough data to learn anything.
A sensible starting point for a modest budget:
- One prospecting campaign with one or two ad sets, a broad or Advantage+ audience, automatic placements and three to six ads built on genuinely different ideas.
- One retargeting campaign for site visitors and people who engaged, but only once that audience is large enough to absorb a budget without hammering the same handful of people.
- Nothing more until the first campaign produces results you can measure in your own records.
Set the budget by working backwards. Estimate what a lead or sale is likely to cost, multiply it by the weekly volume an ad set needs to learn, and compare the answer with what you can afford. If it is out of reach, run fewer ad sets or optimise for a more frequent event rather than spreading the money thinly. Then leave things alone. Significant edits to budget, audience or creative send an ad set back into learning, so make changes in planned batches, give each one at least a week, and resist checking results every morning.
Creative does most of the work
With targeting largely automated, the ad itself is the biggest lever you hold. The image or video decides who stops scrolling, and because Meta learns from who responds, it also decides who the ad is shown to next.
What I look for in Meta creative for UK businesses:
- An obvious opening. The product, the problem or a person should be on screen in the first second, not after a logo animation.
- The right shape for each placement. Vertical 9:16 for Reels and Stories, 4:5 or square for feeds. An ad cropped awkwardly into every slot looks like an ad, and people move past it.
- Readable on mute. Many people scroll with the sound off, so add captions or on-screen text to any video.
- Real rather than glossy. Phone-filmed footage of you, your team, your premises or a customer using the product tends to sit more naturally in the feed than studio work, and it is far cheaper to replace.
- A specific offer. “Book a free 15-minute call” or “Free delivery over £40” gives people a reason to act. “Find out more” does not.
Test different ideas, not small tweaks. Three ads built on different angles, say price, the customer’s problem and how the product is made, teach you far more than three versions of the same picture with different button colours. Watch frequency (how many times the average person has seen the ad) alongside click-through rate. When frequency climbs and clicks fall, the audience is tired of the ad, and the answer is new creative rather than a bigger budget.
Where to send people: form, message, call or landing page
For a service business, where the click leads shapes the kind of enquiry you get as much as the targeting does. There are four main options.
Instant forms
With Facebook and Instagram lead ads, a form opens inside the app with the person’s name, email and phone number already filled in. That makes them the cheapest way to collect enquiries and, often, the weakest in quality, because sending one takes two taps. Choose the “higher intent” form type, which adds a review screen, ask one or two qualifying questions, link your privacy policy (Meta requires one), and connect the form to your email or CRM so someone can call back within the hour. Leads left sitting in Meta for days go cold.
WhatsApp and Messenger
Click-to-message ads open a conversation instead of a form. They suit businesses where buyers want to ask something before committing and someone can reply quickly, such as beauty treatments, trades, restaurants and tutoring. A message that goes unanswered all weekend wastes the click, so only run these when replies are covered.
Calls
Call ads add a “Call now” button. They work for urgent local services seen on a phone, provided somebody answers. Schedule them for staffed hours; on Meta, ad scheduling needs a lifetime budget rather than a daily one.
A landing page on your own site
Sending people to your website usually costs more per lead, but you control the message, can qualify people properly and keep the data in your own systems. The page needs to match the ad, load quickly on a phone and make the next step obvious. Shops should link to the product shown in the ad, never the homepage.
My rule of thumb: start with a landing page when the offer needs explaining or you want fewer, better enquiries; start with an instant form when speed matters more and you can follow up the same day. Whichever you choose, judge it on how many leads become customers, not on cost per lead alone.
UK advertising rules and keeping your account healthy
Two sets of rules apply to every UK Meta ad: Meta’s advertising standards, and the UK’s own advertising rules. Paid social ads are covered by the CAP Code, the rulebook for non-broadcast advertising that the Advertising Standards Authority enforces, in the same way as a leaflet or a poster.
The points that catch small businesses most often:
- Claims need evidence. “Best in London”, “lowest prices” or a promise of results needs proof you already hold before the ad runs.
- Prices must be honest. Prices shown to consumers should include VAT and any compulsory fees.
- Health and beauty claims are tightly controlled. Prescription-only medicines, including anti-wrinkle injections, cannot be advertised to the public, and ads for cosmetic procedures must not be aimed at under-18s.
- Paid partnerships are ads. Content an influencer is paid or gifted to post must be clearly labelled as advertising.
- Some sectors carry extra rules. Alcohol, gambling and financial products each have their own sections of the code. Financial promotions must also meet FCA requirements, and Meta asks gambling advertisers for written permission before their ads can run.
Meta adds its own layer. Ads about social issues, elections or politics need Meta’s authorisation and a “Paid for by” disclaimer. Ads for credit, employment or housing may need to be declared as a special ad category, which removes or limits options such as age, gender and narrow location targeting. Recruitment agencies, letting agents and lenders should check Meta’s current requirements for UK ads before building anything, because they have changed more than once. Meta also rejects copy that implies it knows something personal about the viewer, so “Struggling with debt?” fails where “Help with managing debt” may pass.
To keep the account itself safe, avoid sudden large spend on a brand-new ad account, before-and-after images, landing pages that do not match the ad, and anything that looks like an attempt to get round a rejection. If you think an ad was rejected wrongly, request a review in Account Quality instead of uploading the same ad again.
Measuring results honestly
Ads Manager counts conversions using its own attribution setting, by default an action within seven days of a click or one day of a view. GA4, your shop platform and your CRM all count in different ways, so the figures will not match. I explain the main reasons in why GA4 and Facebook report different conversion numbers.
Use Ads Manager to compare ads and ad sets with each other. Use your own records to decide whether the whole thing pays:
- Record the source of every enquiry and sale in your CRM or a simple spreadsheet, and tag every ad link with UTM parameters so GA4 can attribute the visit.
- Each month, count the leads that became paying customers and divide your total spend, including creative and management, by that number.
- Compare total new customers and revenue in periods with ads against periods without. It is crude, but it is the most honest check on whether the ads add anything you would not have had anyway.
What Meta ads cost in the UK
There is no set price. You choose a budget, Meta runs an auction for each impression, and what you pay depends on the audience you are trying to reach, the time of year, how many other advertisers want the same people and how well your ads perform. Prices typically rise in the run-up to Black Friday and Christmas, when retailers compete hardest for attention.
Plan for the whole cost, not just the ad spend: the money paid to Meta, the time or fees involved in making creative, and management if someone runs the account for you. For typical cost per click and cost per lead ranges, see my UK ad benchmarks for Google and Meta, and treat them as a sense check rather than a forecast.
Mistakes that waste most of the budget
When a small account is not paying, the cause is usually one of these:
- Boosting posts instead of using Ads Manager. Boosted posts have fewer objectives and controls and are often optimised for likes rather than enquiries.
- Optimising for the wrong event, such as clicks or button taps, so Meta hunts for clickers and the reports look better than the bank balance.
- Too many ad sets on too little budget, edited every day, so none of them ever leaves the learning phase.
- One ad left running for months while frequency climbs and results fade.
- Slow follow-up, which wastes enquiries that were already paid for.
When it makes sense to get help
Most of what is in this guide is within reach of an owner who can give it a few hours a week. It is worth bringing someone in when the tracking is beyond you, when spend is high enough that small inefficiencies cost real money, or when you have run ads for a couple of months and still cannot tell whether they pay. I offer Facebook and Instagram ads management for UK businesses, and I am happy to look over an existing account first and tell you plainly what I would change.
