Google Ads can be the single best investment your business makes — or the fastest way to burn through your budget. I've seen Polish businesses in the UK spend £500 a month and land 30 new clients. I've also seen others throw £2,000 at it and get absolutely nothing back. The difference? Campaign setup. And that's exactly what this guide is about.
I'll walk you through the whole thing step by step — from the basics, through targeting and keywords, all the way to AI automation. You don't need to be an advertising expert. You just need to know what to watch out for and where most businesses go wrong. Whether you run a construction firm, a beauty salon, or an accounting practice — the principles are the same.
Step 1: Understand how Google Ads actually works
Before you put any money into Google, there's one thing you need to understand: it's an auction. Someone types "Polish accountant London" — and in a fraction of a second, Google runs a bidding war between all the businesses that want to appear for that phrase. But the highest bidder doesn't always win. Google also factors in the quality of your ad (Quality Score), how relevant your landing page is, and how well your advert actually answers the searcher's question.
What does that mean in practice? That a better ad with a smaller budget can beat a worse ad with a bigger budget. That's why campaign setup and ongoing optimisation matter more than the raw amount you spend. A well-configured campaign at £500 can outperform a chaotic one at £2,000.
Step 2: Starter budget — how much do you actually need?
"How much do I need to spend?" — that's the first question everyone asks. It depends on your industry and location, but here are some realistic ranges so you're not going in blind:
- Local services (cleaning, plumbing, hairdressing): £300–600/month
- Professional services (accounting, legal, consulting): £500–1,200/month
- E-commerce (online shop): £800–2,000/month
- B2B / niche services: £400–800/month
From experience, my advice is: start with a minimum of £500 per month and give it at least three months. Why so long? Because the first four to six weeks are the algorithm's learning phase — Google collects data on who's clicking, who's converting, when, and where. If you pull the plug after one month because "it's not working", you've wasted your money, because you never gave the system enough time to optimise. It's like planting a tree and ripping it out after a week because there's no fruit.
Step 3: Geographic targeting — precision saves money
One of the biggest mistakes Polish businesses in the UK make is targeting too wide an area. If you run a hair salon in Ealing, you don't need ads showing across all of London — and certainly not across the whole of Britain. Google Ads lets you target with precision:
- Radius around your location — e.g. 10 miles from your premises.
- Specific postcodes — ideal for local services.
- Cities and regions — e.g. Greater London, West Midlands, Greater Manchester.
- Exclusions — you can block areas where you don't offer services.
An important tip: in Google Ads settings, change the location option from "People in, or who show interest in" to "People in or regularly in". The default setting shows your ads to people who merely "show interest" in a location — which means your London-based business ad could appear to someone in Warsaw who simply searched for something related to London.
Step 4: Keywords — Polish or English?
This is the critical question for every Polish business in the UK. The answer: it depends on your target audience. Here's how to think about it:
Polish keywords — when?
When your clients are Polish people living in the UK who search for services in their own language. Examples: "polska księgowa londyn", "polski mechanik manchester", "polskie biuro rachunkowe uk". These phrases have lower competition and a lower CPC (cost per click) than their English equivalents — often two to three times cheaper. The trade-off? Lower search volume. But the conversion rate is frequently higher because you're reaching a perfectly targeted group.
English keywords — when?
When your clients are the general UK population — regardless of nationality. English phrases have higher search volume but stiffer competition. For example: "accountant London" costs £8–15 per click, while "polska księgowa londyn" costs £1–3.
Our recommendation: a bilingual strategy
Create two separate campaigns — one with Polish keywords and one with English keywords. Each with its own budget, its own ad copy, and its own landing pages. Never mix languages within a single campaign — it will tank your Quality Score and push costs up.
Step 5: Conversion tracking — without it you're throwing money away
The single biggest mistake we see from Polish businesses in the UK: launching a campaign without conversion tracking set up. It's like driving blindfolded — you're spending money but have no idea what's working and what isn't. A conversion is any desired user action:
- Filling in a contact form.
- A phone call from the ad (call tracking).
- An online purchase.
- Booking an appointment.
- Downloading a price list or brochure.
In 2026, setting up conversions requires Google Tag Manager and GA4 (Google Analytics 4). If you're not sure how to do this, that's the point where it's worth bringing in an agency. Badly configured conversions are actually worse than no conversions at all, because they lead to false optimisations — the algorithm starts chasing the wrong signals.
Step 6: AI-powered campaign automation — the future is already here
Google Ads in 2026 is not the same system it was five years ago. Artificial intelligence now handles a significant chunk of campaign optimisation. Here are the AI tools you should know about:
- Performance Max — automated campaigns that show your ads across Search, YouTube, Gmail, Maps, and Display simultaneously. Google decides where your ad performs best.
- Smart Bidding — automatic bidding strategies (Target CPA, Target ROAS, Maximise Conversions) that adjust bids in real time based on hundreds of signals.
- Responsive Search Ads — you provide up to 15 headlines and 4 descriptions, and Google automatically tests combinations and picks the most effective ones.
- Broad Match + Smart Bidding — in 2026, Google recommends broad match keywords paired with automatic bidding. The AI finds valuable searches on its own.
An important caveat: automation only works well once you have enough conversion data. That's why Step 5 is so critical — without conversion tracking, the AI has nothing to learn from.
- No conversion tracking — you're spending money in the dark.
- Geographic targeting too broad — you're paying for clicks from people who'll never become clients.
- Mixing languages in one campaign — Polish keywords + English ad copy = terrible Quality Score.
- Linking to the homepage instead of a dedicated landing page.
- Giving up after 2–4 weeks — the algorithm needs at least 6 weeks to learn.
- Ignoring negative keywords — without them you're paying for irrelevant searches.
- No ad extensions (sitelinks, callouts, structured snippets) — you're reducing your chance of getting a click.
ROI from Google Ads — what to realistically expect
A well-managed Google Ads campaign for a Polish business in the UK should achieve a ROAS (Return on Ad Spend) of 3:1 to 8:1 — meaning for every pound you spend, you get £3–8 in revenue. Naturally, it varies by industry:
- High-value services (legal, accounting, B2B): ROAS 5:1–10:1, because a single conversion can be worth hundreds or thousands of pounds.
- Local services (hairdresser, cleaning): ROAS 3:1–5:1, due to the lower value of each individual transaction.
- E-commerce: ROAS 4:1–8:1, depending on product margins.
If after three months your campaign isn't hitting at least a 2:1 ROAS — something's off with the setup, the landing page, or the offer itself. That's the moment for an audit and optimisation, not for throwing more money at it.
How MAC LEE DESIGNS manages Google Ads campaigns
We've been managing Google Ads campaigns for Polish businesses in the UK for years. Our approach rests on three pillars:
- Bilingual strategy: Separate campaigns in Polish and English, with dedicated landing pages and independent budgets for each. No mixing of languages, ever.
- AI-powered automation: We use Performance Max, Smart Bidding, and our own scripts to automate reporting and optimisation. But always with human oversight — AI doesn't replace strategy.
- Full transparency: You get access to the Google Ads account and can see every penny spent. Monthly reports with results, recommendations, and a plan for the following month.
We don't manage campaigns blindly. Every decision is backed by data — from Google Analytics 4, Search Console, and Google Ads itself. If something isn't working, we adjust the strategy within days, not weeks.
Summary — your action plan
Here are six steps to get your Google Ads up and running effectively in the UK:
- Set up a Google Ads account and connect it to GA4 and Google Tag Manager.
- Configure conversion tracking — before launching any campaign.
- Create two campaigns — one in Polish, one in English — with separate targeting for each.
- Set up precise geographic targeting and change the location settings.
- Plan your budget for at least three months — give the algorithm time to learn.
- Monitor results weekly and optimise based on data.
If this all sounds complicated — that's because it is. Google Ads is a powerful tool, but it demands knowledge, experience, and continuous optimisation. That's why most Polish businesses in the UK that succeed with Google advertising work with a professional agency rather than trying to do everything on their own.
