Google Ads for Small Businesses in the UK: Setting Up a First Campaign That Brings Enquiries

A UK small business's first Google Ads campaign should usually be a Search campaign rather than Performance Max. Build it on a few tightly themed keywords, target only people who are actually in your service area, add call and location assets, and set up tracking for calls and form enquiries before you spend anything. Run it on a fixed test budget, read the search terms report every week, and scale only what produces real enquiries.

This guide is for owners of trades businesses, clinics and other local services in towns such as Oxford, Abingdon, Banbury, Reading or Swindon. It suits owners who want to run Google Ads themselves, or who want to know what an agency should be doing for them.

Should your first campaign be Search or Performance Max?

Start with Search. A Search campaign shows text ads only when someone searches for the keywords you choose, so you can see exactly which searches cost you money and which brought enquiries.

Performance Max is a goal-based campaign that runs across all of Google's inventory from one campaign: Search, YouTube, Display, Discover, Gmail and Maps. Google positions it as a way to "complement your keyword-based Search campaigns" (Google Ads Help, accessed Oct 2026). It gives you search themes, campaign-level negative keywords and brand exclusions, and Google has been adding search terms and channel reporting since April 2025 (Google, 30 Apr 2025).

It still depends on automation learning from your conversion data, and a new account has none. Run Search first, collect several weeks of tracked enquiries, and test Performance Max afterwards, if at all, as an addition. Where a search matches an exact match keyword in a Search campaign, that keyword takes priority over Performance Max (Google Ads Help).

Check the network settings too. Search partners are included by default (Google Ads Help, accessed Oct 2026), and a Search campaign can also show on the Display Network through Display Expansion (Google Ads Help, accessed Oct 2026). For a first test, switch both off, so the results reflect Google Search alone.

How should you set location targeting around a town?

Target a radius or a list of towns around your base, then change the location option from "Presence or interest" to "Presence". If you leave the default, your ads can also reach people outside the area who have only shown interest in it.

Google offers two options (Google Ads Help, accessed Oct 2026):

• Presence or interest (the default and Google's recommendation) reaches people "likely to be in or regularly present in" your locations, and people who have "shown interest in" them.
• Presence reaches only people "likely to be located, or regularly located" in your target locations.

A plumber in Witney or a physiotherapy clinic in Didcot can only serve people who are there, so "Presence" is normally the right choice. You can set a radius in miles around an address (Google Ads Help, accessed Oct 2026). Draw it around the area you actually travel to, not the whole county, and exclude areas you never serve.

Which keyword match types should you use?

Use phrase match and exact match for a first campaign, and add broad match only once conversion tracking has a few weeks of data behind it. Match types no longer work as literally as they once did, so understand the current definitions (Google Ads Help, accessed Oct 2026):

• Broad match (no symbols): ads "may show on searches that are related to your keyword", including searches that don't contain its words.
• Phrase match ("emergency plumber"): ads "may show on searches that include the meaning of your keyword". The meaning can be implied, and the search can be more specific.
• Exact match ([emergency plumber]): ads "may show on searches that have the same meaning or same intent as the keyword". This reaches the fewest searches.

Even exact match covers same-meaning searches, so negative keywords and the search terms report matter as much as the match type. Group keywords tightly by service: "boiler repair", "boiler installation" and "gas safety certificate" each get their own ad group and landing page.

How do negative keywords work?

Negative keywords stop your ads showing for searches you don't want. They have their own match rules, which differ from those for ordinary keywords (Google Ads Help, accessed Oct 2026):

• Negative broad (the default) blocks a search only if it contains all of the negative's words, in any order.
• Negative phrase blocks searches that contain the words in the same order, even with other words around them.
• Negative exact blocks only that exact search, with no extra words.
• Negatives "don't match to close variants", and you need to add synonyms and singular or plural versions yourself.

Start with a list before launch: job-seeker terms (jobs, salary, apprenticeship, course), do-it-yourself terms (how to, DIY), and services or areas you don't cover. A purely private clinic may add "NHS".

Which ad assets matter for a local business?

Write one responsive search ad per ad group, then add call, location and sitelink assets, which give people more ways to contact you.

• Responsive search ads: up to 15 headlines of 30 characters and 4 descriptions of 90 characters. Google mixes them, and it says pinning "isn't recommended for most advertisers" (Google Ads Help, accessed Oct 2026). Put the service and the town in several headlines.
• Call assets show your number with the ad. Schedule them to show only when someone is there to answer (Google Ads Help, accessed Oct 2026).
• Location assets show your address, a map and the distance to your premises. They come from your Google Business Profile, so you need access to the profile that lists your location (Google Ads Help, accessed Oct 2026). If the profile is weak, fix it first: our local SEO guide for Oxfordshire businesses covers how.
• Sitelinks add links to specific pages. You need at least two for them to show, sitelink text is limited to 25 characters, and Google recommends at least six with descriptions (Google Ads Help, accessed Oct 2026). Use pages that help someone decide: services, prices, reviews and service areas.

How do you track calls and form enquiries?

Set up a conversion action for each kind of enquiry before launch. Without it you can't tell good keywords from bad, and Google states that "you must set up conversion tracking to use" Maximise conversions bidding (Google Ads Help, accessed Oct 2026).

Calls. Turn on call reporting. Google then shows a Google forwarding number on your call and location assets, and records call start time, duration and whether the call connected (Google Ads Help, accessed Oct 2026). Google Ads tracks several kinds of call conversion (Google Ads Help, accessed Oct 2026):

• Calls from ads, made directly from your call or location assets.
• Calls to a number on your website, using a forwarding number that the Google tag shows on your site after an ad click.
• Clicks on a number on your mobile site. These track the tap, not the call itself.

Set a minimum call length for the first two, so that wrong numbers and sales calls don't count as enquiries.

Forms. Track a confirmed submission, not a visit to the contact page. In Google Analytics 4, mark the submission as a key event, an event that "measures an action that's particularly important to the success of your business", then create a Google Ads conversion from it (Analytics Help, accessed Oct 2026). For leads, set counting to "One": Google suggests this because usually "only one, unique lead per ad click likely adds value" (Google Ads Help, accessed Oct 2026).

Consent. In the UK, the ICO's guidance on PECR says the exception for analytics "does not apply to purposes related to online advertising". Measuring whether someone clicked an advert, or sharing site activity with advertising partners for conversion tracking, needs consent (ICO, accessed Oct 2026). Your cookie banner has to offer a real choice, and your reports will undercount people who decline.

Test every conversion yourself before launch: make a call, submit a form, and check that each one appears. For more on setting up measurement on a new site, see what to do after your website launches.

How much should you budget for a test?

Work out a budget from your own keyword data rather than from someone else's averages. Click prices vary by trade, town and month, which is why this guide doesn't quote any.

1. Pull bid ranges from Keyword Planner for your main keywords and your target area. The "high range" is roughly the 80th percentile of what advertisers have paid for a top-of-page position, and the "low range" roughly the 20th (Google Ads Help, accessed Oct 2026).
2. Decide how many clicks a day you need to learn something, then multiply by a cost per click towards the high range. That gives a daily budget.
3. Commit to a fixed test period, such as six to eight weeks, and don't judge the campaign in its first few days.

Remember how Google spends a budget. On a given day a campaign "might spend up to twice your average daily budget", but over a month it will spend "no more than 30.4 times your average daily budget" (Google Ads Help, accessed Oct 2026). Plan the monthly figure, not the daily one.

How do you read the search terms report?

The search terms report shows the actual searches that triggered your ads. A keyword is what you bid on; a search term is what the person typed. Google notes that terms with low search volume are left out of the report for privacy, so it won't list every search (Google Ads Help, accessed Oct 2026).

Go through it weekly for the first two months:

• Irrelevant searches: add them as negative keywords, choosing the narrowest match type that does the job.
• Searches that converted: add them as phrase or exact match keywords, so you control their bids and ads.
• Locations that don't fit: if place names outside your area appear, check that location targeting is set to "Presence".
• Searches with clicks but no enquiries: check whether the landing page answers what was searched before you blame the keyword.

What can UK ads claim under the CAP Code?

The UK Code of Non-broadcast Advertising (the CAP Code), enforced by the Advertising Standards Authority, applies to "paid-for search listings" (ASA, accessed Oct 2026).

The rules that most often affect small businesses (CAP Code section 3, accessed Oct 2026):

• 3.1: marketing "must not materially mislead or be likely to do so".
• 3.7: you must hold documentary evidence for claims "consumers are likely to regard as objective". "Oxford's highest-rated electrician" or "fixed in 1 hour" needs proof. Obvious exaggeration is allowed if it doesn't materially mislead (3.2).
• 3.18, 3.22 and 3.23: quoted prices must include non-optional taxes and fees, "from" and "up to" claims must not exaggerate what customers are likely to get, and "free" has a strict meaning.
• 3.44 to 3.46: no fake reviews, a clear disclosure where reviews were incentivised, and no misleading selection of reviews. Be careful with "5-star rated" headlines.

Clinics have extra rules in section 12 (CAP Code section 12, accessed Oct 2026). Objective claims must be backed by evidence, "if relevant consisting of trials conducted on people" (12.1). Practitioners must have relevant and recognised qualifications (12.3). Under 12.12, prescription-only medicines and treatments "may not be advertised to the public". The ASA's guidance confirms this covers Botox, including indirect references (ASA, accessed Oct 2026). Aesthetic clinics should advertise consultations, not the drug.

Google's own Misrepresentation policy also bars "inaccurate claims or claims that entice the user with an improbable result" (Advertising Policies Help, accessed Oct 2026).

This is general information, not legal advice. For a specific claim, CAP's Copy Advice service can review the ad before it runs.

When should you stop or scale?

Judge the campaign on enquiries and booked jobs, not clicks. At the end of the test period, put each ad group in one of three groups:

• Scale when its cost per enquiry is below what an enquiry is worth to you and enquiries turn into booked work. Raise the budget in steps, checking that each increase still brings extra enquiries.
• Fix when it gets clicks but few enquiries. Check the search terms, the landing page and how quickly calls are answered.
• Stop when the search terms stay mostly irrelevant despite negatives, or the cost per enquiry stays above what the work is worth after a fair test.

Once Search is profitable and conversions flow steadily, test Smart Bidding, broader match types or Performance Max, one change at a time.

2. Set up and test conversions for calls and forms, behind a consent banner that offers a real choice.
3. Build one Search campaign: "Presence" targeting, search partners and Display off, two to four tight ad groups, negatives, and call, location and sitelink assets.
4. Launch on the test budget and check search terms twice a week.

Days 31–60: clean up

1. Review search terms weekly, adding negatives and promoting converting searches.
2. Improve the landing page with the most clicks and fewest enquiries.
3. Check every headline against the CAP Code and keep evidence for objective claims.

Days 61–90: decide

1. Compare cost per enquiry and booked jobs by ad group, then scale, fix or stop each one.
2. Only then consider Smart Bidding or a Performance Max test.

Frequently asked questions

Is Performance Max good for a small local business?

It can work once conversion tracking has data behind it, but it is a poor starting point. A Search campaign shows you which searches produce enquiries, and that is what a new account needs to learn first.

Do I still need negative keywords if I use exact match?

Yes. Exact match now covers searches with the same meaning or intent, and negative keywords don't match close variants, so you need to add plurals and synonyms yourself.

How do I count phone calls as conversions?

Turn on call reporting, create a "Calls from ads" conversion with a minimum call length, and add a website call conversion that uses a Google forwarding number on your site. Then test both with a real call.

Can I say "best" or "number one" in a UK ad?

Obvious exaggeration is allowed if it doesn't materially mislead. A claim that people are likely to take as objective, such as "number one in Oxfordshire", needs documentary evidence under CAP Code rule 3.7.

Who should own the Google Ads account?

You should. At Digital Architect, we create ad accounts in the client's name with the client as admin, charge a fixed monthly fee rather than a percentage of ad spend, and track every call, WhatsApp chat and form. Whoever you work with, make sure the account and its data stay yours.
