How to Run Google Ads for a Small Business
When you run Google Ads for a small business, your ads can appear at the top of Google for searches your customers are already making, and you only pay when someone clicks. Set up correctly, with the right keywords, ad copy, landing page and conversion tracking, it’s one of the most powerful lead generation tools available. Set up poorly, it burns budget fast. This guide shows you how to do it right.

Before you set up your first campaign
Four things need to be in place before you touch the Google Ads interface. Skipping them is how small businesses waste thousands of pounds on ads that deliver nothing.
Google handles billions of searches a day, and right now people in your area are searching for exactly what your business offers. When small businesses run Google Ads, they are using PPC (pay per click), so this is also a practical guide to small business PPC. Learning how to run Google Ads for a small business starts away from the ads themselves: with your website, your tracking and your numbers. Ads can deliver immediate, measurable leads while your SEO builds momentum, but only on these foundations.
- A website that converts. Sending paid traffic to a slow, unclear or trust-lacking website is like filling a leaky bucket. Before spending a penny on ads, your landing page needs a clear headline, a strong offer, visible contact details, genuine trust signals (reviews, accreditations) and a clear call to action. A poorly converting page can waste most of your ad budget however well the campaign is set up.
- Conversion tracking. If you can’t measure what your ads are generating, you can’t optimise them. Before launching, set up conversion tracking in Google Ads for at least one of these: form submissions, phone calls, purchases or email link clicks.
- A clear idea of customer value. You need to know roughly what a customer is worth to you. If an average customer is worth £500, you can afford to pay more per lead than if they’re worth £50. This sets how much you can sensibly bid per click and what a profitable cost per acquisition looks like.
- A Google Ads account in Expert Mode. Create your account at ads.google.com. During setup, Google will push you to create a campaign immediately; skip this with the “Switch to Expert Mode” option. Smart campaigns sound easier but give you far less control and often waste budget. Always use Expert Mode.
Setting up your first campaign
For most UK small businesses that run Google Ads, a Search campaign is the right place to begin. Search ads appear when people actively search for your keywords: high-intent traffic from people already looking for what you offer.
- Campaign type: Search. Avoid Display, Shopping or Performance Max until you have Search campaigns running profitably. Those formats need more sophisticated management and are harder to control as a beginner.
- Campaign goal. Select the goal that matches your objective: “Leads” for enquiries and form submissions, “Sales” for ecommerce, “Website traffic” if you’re building awareness. The goal affects how Google optimises the campaign’s bidding.
- Geographic targeting. Critical for local businesses. Target the specific areas you serve, not the entire UK. A Bristol plumber should target Bristol and the surrounding postcodes. Choose “People in or regularly in your targeted locations” (not “interested in”), so you don’t pay for people merely searching about an area.
- Campaign structure: ad groups. Organise the campaign into tightly themed ad groups of closely related keywords, each with ads written specifically for them. A plumber might have separate groups for “Emergency Plumber Bristol”, “Boiler Repair Bristol” and “Bathroom Installation Bristol”. Tight structure improves Quality Score and keeps ads relevant.
Choosing the right keywords
Keyword selection is the single most important decision in any campaign. The wrong keywords waste money; the right ones generate profitable leads.
Focus on high commercial intent keywords: terms people search when they’re ready to hire or buy, not just researching. Compare these:
| Low intent (avoid for ads) | High intent (target for ads) |
|---|---|
| what is a boiler service | boiler service Bristol |
| types of website design | website designer Bristol quote |
| how does SEO work | SEO agency Bristol |
| what is personal injury compensation | personal injury solicitor Bristol |
Use negative keywords from day one
Negative keywords stop your ads showing for irrelevant searches, and they’re one of the most important money-saving tactics available. Depending on your business, add negatives like “free”, “DIY”, “course”, “how to”, “jobs” and “salary” before launch. Review your search terms report weekly and add new negatives regularly.
Start with 5–15 keywords per ad group
Resist the temptation to add hundreds of keywords. Start lean and focused. A tight set of 8–12 high-intent keywords per ad group performs better than a bloated list of loosely related terms.
Keyword match types explained
Match types control how closely a search must match your keyword for your ad to show. Getting them wrong is one of the most common and expensive beginner mistakes.
| Match type | How to write it | What it does | Best for |
|---|---|---|---|
| Broad match | plumber bristol | Shows for related searches, synonyms and loose interpretations. A very wide net. | Advanced campaigns with Smart Bidding and strong negative keyword lists |
| Phrase match | “plumber bristol” | Shows when the search contains your phrase, in any order with other words. | Balanced reach and relevance; good for most campaigns |
| Exact match | [plumber bristol] | Shows only for that exact search or very close variants. | High-priority, high-value terms where precise control matters |
For beginners: start with phrase match and exact match. Avoid broad match until you have conversion data and are comfortable managing large negative keyword lists. Broad match can quickly drain budget on irrelevant traffic if it isn’t carefully managed. Google’s AI Max goes further than broad match. Our AI Max for Search guide explains when it is worth a test.
Writing ads that get clicks
Search ads use Responsive Search Ads (RSAs): you provide up to 15 headlines and 4 descriptions, and Google tests combinations to find what performs best.
Headlines (up to 15, max 30 characters each)
Headlines are the most visible part of your ad. Google mixes and matches them, so each one should make sense in any combination. Include:
- Your primary keyword (“Emergency Plumber Bristol”).
- A key benefit or USP (“Same-Day Call-Outs Available”).
- Social proof, if it’s true (“500+ Five-Star Reviews”).
- A call to action (“Get a Free Quote Today”).
- Trust signals (“Gas Safe Registered Engineers”).
- Location-specific terms (“Covering BS1–BS16 Postcodes”).
Descriptions (up to 4, max 90 characters each)
Descriptions add context: reinforce your USP, answer common objections and include a clear call to action. Write each one as if it could appear alone, without relying on the others to complete the message.
Ad strength rating
Google rates your ad as Poor, Average, Good or Excellent. The rating doesn’t directly control performance, but using all 15 headlines and all 4 descriptions, and keeping them diverse rather than repetitive, generally produces better results over time.
Ad assets (formerly extensions)
Assets are extra information that can appear alongside your ads and take up more space in the results. Always add:
- Sitelinks (links to specific pages).
- Callouts (short USP phrases).
- Structured snippets (a list of services).
- Call asset (your phone number).
- Location asset (your address).
- Lead form asset, where it applies.
Setting budgets and choosing a bidding strategy
Budget and bidding determine how competitive your ads are and how much you spend. Getting this right is the difference between profitable campaigns and a money pit.
Your daily budget is the average you’re willing to spend per day. Google can spend up to twice it on busy days but averages out over the month. For UK small businesses, we recommend at least £300 a month (about £10 a day) for a local campaign and £600 a month for one aimed at the whole UK; below this, campaigns often can’t gather enough clicks to optimise. For a realistic framework by industry, see our guide how much should you spend on Google Ads in the UK?

| Strategy | How it works | When to use it |
|---|---|---|
| Maximise Clicks | Gets the most clicks for your budget | New campaigns with no conversion data; use temporarily, then switch |
| Target CPA | Aims for conversions at your target cost per acquisition | Once you have 30–50 conversions a month; very effective |
| Maximise Conversions | Gets the most conversions for your budget | A good mid-point before Target CPA; needs some conversion history |
| Target ROAS | Optimises revenue relative to ad spend | Ecommerce with good conversion volume and revenue data |
| Manual CPC | You set bids by hand for each keyword | Advanced users wanting full control; rarely right for beginners |
For beginners: start with Maximise Clicks (with a manual CPC bid cap) to gather data. Once you have 30+ conversions, switch to Maximise Conversions or Target CPA. Don’t set Target CPA too aggressively at first: set it 20–30% above your real target to give the algorithm room to learn.
Landing pages: where campaigns win or lose
Your ad gets the click; your landing page gets the conversion. A great ad sending traffic to a poor page is one of the most common and costly Google Ads mistakes.
Message match
The landing page headline and content must closely match the ad’s promise. If your ad says “Emergency Plumber Bristol, Available Now”, the page should immediately confirm emergency availability in Bristol. Any disconnect sends visitors straight back, wasting the click you paid for.
Landing page essentials
- A clear, specific headline that matches your ad copy.
- The primary call to action above the fold, visible without scrolling.
- A prominent phone number, click-to-call on mobile.
- Social proof: reviews, ratings, logos, accreditations.
- Fast loading, ideally under 3 seconds on mobile.
- A short form (name, email, phone, brief message; nothing unnecessary).
- Trust signals: a privacy note, a secure site, a no-spam promise.

Setting up conversion tracking
Without tracking, Google Ads is guesswork. You can’t tell which keywords generate leads, which ads perform or whether the campaign is profitable. This part is non-negotiable.
- Form submissions: fire a conversion when someone submits your contact or enquiry form, via a thank-you page URL or a form event in GA4.
- Phone calls: use call assets with call tracking to record calls from ads, and track calls from your website after an ad click.
- Purchases: for ecommerce, track every completed order with its revenue value so you can calculate ROAS.
- Email clicks: if your main CTA is an email link, track clicks on it as a soft conversion.
How to set it up
In Google Ads, click Goals, then Conversions, then Summary, then New conversion action. For website conversions you’ll add a Google Ads tag to your site, or import your GA4 key events into Google Ads. Setup takes 30–60 minutes and is one of the highest-value tasks in any campaign.
Costly mistakes small businesses make when they run Google Ads
These common errors waste budget in small business accounts, and each one is easy to check.
- Using Smart campaigns instead of Expert Mode. Smart campaigns give Google too much control and often buy irrelevant traffic. Always use Expert Mode.
- No negative keywords. Without negatives, broad and phrase match keywords will show your ads for wildly irrelevant searches. Build a solid negative list before launch.
- Sending traffic to the homepage. Your homepage is not a landing page. Send ad traffic to specific pages that match the ad’s intent exactly.
- No conversion tracking. Without it you can’t know which keywords and ads generate leads. You’ll be optimising blind.
- Setting the budget too low. £3–£5 a day gives Google 1–2 clicks a day, which tells you nothing. Budget for at least 50–100 clicks a week to see meaningful patterns.
- Constant fiddling. Google’s algorithms need 2–4 weeks to learn. Daily changes stop the algorithm settling and waste the learning phase.
- Targeting the whole UK by default. Google often defaults to broad geographic targeting. Always restrict it to your actual service area.
- Ignoring Quality Score. A low score means you pay more per click than competitors. Improve keyword-to-ad relevance and landing page experience; our guide Google Ads Quality Score explained covers it in full.

Google Ads questions from small businesses
Rather talk it through? See our Google Ads management service, priced at £30 an hour.
How much does it cost to run Google Ads for a small business in the UK?
There’s no fixed minimum; Google Ads is pay per click. In practice, we recommend at least £300 a month (about £10 a day) in ad spend for a local campaign and £600 a month for a UK-wide one, so you get enough clicks for meaningful results. Monthly spend varies hugely by industry: a local trade might start at £500–£1,000 a month, while a solicitor or financial services firm might need £1,500–£3,000 or more because of higher keyword competition and CPCs.
Can a small business run Google Ads without an agency?
You can run it yourself, and this guide covers the fundamentals. Managing ads well is a skill, though, and it takes regular time: checking search terms, adding negative keywords and judging changes on enough data. If that time costs you more than a manager would, hand it over. Ours is £30 an hour, billed only for the hours used.
How quickly will I see results from Google Ads?
Unlike SEO, Google Ads can start bringing visits as soon as your ads are approved and running. How soon the first enquiry comes depends on your budget, your offer and your landing page. Expect the first few weeks to be a settling period while Google’s bidding learns and you refine keywords and targeting based on real data.
What is a good click-through rate (CTR) for Google Ads?
It depends on your industry, your keywords and where your ad shows, so there is no single good figure. Watch the trend in your own account: a low or falling CTR suggests your ads aren’t resonating, so rewrite headlines and improve message match. CTR alone doesn’t equal success though: lots of clicks with no conversions is worse than fewer clicks that convert well. If your ads get almost no clicks at all, read why Google Ads get no clicks and how to fix it.
What’s the difference between Google Ads and Google Shopping?
Google Ads (Search) shows text ads when people search your keywords. Google Shopping shows product image ads with price and store name, mainly for ecommerce, managed through Google Merchant Center and set up differently. For most service businesses, Search campaigns are the starting point.
Should I run Google Ads and SEO at the same time?
For most UK small businesses, yes, especially in the early months. Ads provide immediate traffic and leads while SEO builds momentum, and the channels complement each other. As organic rankings improve over 6–12 months, you can reassess your ad spend. Our comparison: SEO vs PPC for small business UK.
Is Google Ads worth it for a small business?
Yes, if three things are in place. You can track the enquiries or sales it brings, a customer is worth far more than a click costs, and you can fund a test of at least 90 days. For a local campaign that means at least £300 a month in ad spend, or £600 for one aimed at the whole UK. Without tracking you cannot tell whether it pays. If clicks in your trade cost more than your margins can carry, SEO is usually the better bet. Already running ads? A free Google Ads audit shows whether yours are paying.
Do I pay for every impression or only when someone clicks?
For standard Search campaigns you only pay when someone clicks your ad (pay per click). Impressions, the times your ad is shown, are free. Appearing in results costs nothing; you pay only for actual visitors sent to your website.
