"Should I do Google Ads or SEO?" — I get asked this by almost every Irish business owner I talk to. And the honest answer is: it depends. But probably not in the way most marketing agencies will tell you.
Let me break down exactly how both work, what they actually cost in Ireland, and which one will deliver better results for your specific situation. No sales pitch — just the numbers.
Google Ads: The Quick Hit
Google Ads puts you at the top of search results immediately. You bid on keywords, set a budget, and start getting clicks within hours. Sounds perfect, right? Here's the reality:
- Average cost per click in Ireland: €1.50-€8.00 depending on industry (legal and medical can hit €15+)
- Typical monthly spend: €500-€3,000 for a small Irish business to get meaningful traffic
- Conversion rate: 3-5% average — meaning for every 100 clicks, 3-5 become enquiries
- The catch: The moment you stop paying, the traffic stops. Completely. Zero residual value.
The maths: At €3 per click and a 4% conversion rate, you're paying €75 per enquiry. If your monthly budget is €1,500, that's 20 enquiries. Sounds okay — until you realise you're paying that every single month, forever, with zero compound benefit.
SEO: The Slow Burn That Compounds
SEO gets you into the organic results — the listings below the ads. It takes longer to kick in (3-6 months typically), but the economics are completely different:
- Cost per click: €0. Once you rank, every click is free.
- Typical investment: €1,000-€2,500/month for ongoing SEO, or a one-time website build with SEO baked in (€3,000-€8,000)
- Click-through rate: Organic results get 70% of all clicks. Ads only get 30%.
- The magic: SEO compounds. Content you create today still brings traffic in 2, 3, 5 years. Each new page adds to your authority.
The maths: After 6 months of SEO, a well-optimised site can generate 500+ organic visitors per month. At the same 4% conversion rate, that's 20 enquiries — for free. Month after month. And the traffic keeps growing.
The Real Cost Comparison Over 12 Months
Total spend: €18,000. Enquiries: ~240. Cost per enquiry: ~€75. What happens when you stop: traffic drops to zero immediately.
Total spend: €5,000 website + €12,000 SEO = €17,000. Enquiries in year 1: ~150 (builds over time). Cost per enquiry: ~€113 in year 1. But in year 2, you're spending €12,000 for potentially 300+ enquiries — €40 each. And it keeps improving.
By year 3, SEO is dramatically cheaper per enquiry than Google Ads. And if you stop SEO, your rankings don't vanish overnight — you'll still get traffic for months or years from the work already done.
When Google Ads Makes Sense
- • New business launch — You need leads NOW while SEO builds momentum
- • Seasonal promotions — Valentine's Day, Christmas, Black Friday pushes
- • Testing new services — Validate demand before investing in SEO content
- • High-margin products/services — If your average sale is €5,000+, the €75 per enquiry is nothing
- • Competitive markets — While you're building organic rankings, ads keep you visible
When SEO Is the Better Investment
- • Local businesses — "Plumber Dublin", "dentist Cork" — local SEO is incredibly effective and relatively quick to rank for
- • Service businesses — Ongoing services where lifetime customer value is high (accounting, web design, maintenance contracts)
- • Content-rich industries — If people search for advice in your field, SEO lets you capture them at every stage
- • Limited budget — If you can only afford one, SEO builds an asset. Ads are a running cost.
- • Long-term thinking — If you plan to be in business for the next 5+ years, SEO is a no-brainer
The Smart Approach: Use Both
The best-performing Irish businesses I work with use both — but strategically:
- • Phase 1 (Months 1-6): Launch Google Ads at a modest budget (€500-€1,000/month) for immediate leads. Simultaneously invest in SEO — website optimisation, content creation, local SEO.
- • Phase 2 (Months 6-12): As organic traffic grows, reduce ad spend on keywords where you're now ranking organically. Redirect that budget to new keyword opportunities.
- • Phase 3 (Year 2+): SEO handles the bulk of your traffic. Ads are used surgically — seasonal pushes, new service launches, competitor conquesting.
This approach means you're never waiting for leads, but you're also building a long-term traffic machine that reduces your dependence on paid advertising over time.
Common Mistakes Irish Businesses Make
- • Running ads to a bad website — Paying for clicks that land on a slow, ugly, or confusing website is burning money. Fix the website first.
- • No tracking setup — If you're not tracking conversions, you have no idea what's working. Google Analytics and call tracking are essential.
- • Expecting instant SEO results — SEO takes 3-6 months to show meaningful results. If someone promises page 1 in 2 weeks, run.
- • Setting and forgetting ads — Google Ads needs weekly optimisation. Unmanaged campaigns waste 50%+ of spend on irrelevant clicks.
- • Choosing one forever — Your marketing mix should evolve. What works in year 1 isn't the same as year 3.
