SEO basics
SEO explained without the jargon: how Google and AI tools decide who shows up, what changed in 2026, and seven steps you can take this week.
Short answer
SEO (search engine optimisation) means making your business easy to find, and easy to trust, when people search online. Done well, it puts you in Google’s normal results, in Google Maps, and in AI answers from tools like ChatGPT and Google’s AI Mode. You don’t pay per click. You earn the spot.
Key takeaways
- SEO means being easy to find and easy to trust
- Google needs to find, understand and trust your pages
- AI tools pick answers from sites that do SEO well
- Your Google Business Profile is the quickest win
- Expect first results in 3–6 months
SEO in one picture: Google is a librarian
Picture Google as a librarian with billions of books. When someone asks a question, the librarian has a second or so to hand over the best book.
To do that, the librarian needs to:
01
Know your book exists
Called crawling and indexing.
SEO is simply making sure all four of those are true for your business.
The three types of SEO
| Type | What it means | Example for a Dublin plumber |
|---|---|---|
| On-page SEO | What’s on your pages: words, headings, photos, FAQs | A page called “Boiler Repair in Dublin 15” that answers real customer questions |
| Technical SEO | How your website works behind the scenes | The site loads in under 3 seconds on a phone and has no broken pages |
| Off-page SEO | What the rest of the internet says about you | Google reviews, a listing on the RGII register, a mention in the local paper |
For a local business, add a fourth: local SEO. That’s your Google Business Profile and showing up in the map. We explain it in our guide to local SEO in Dublin.

What changed in 2026: search is now partly AI
Two years ago, SEO meant “rank in the ten blue links”. Today a search can end in several places:
- Google’s normal results (still the biggest source of website visits)
- AI Overviews, the AI summary at the top of many Google searches
- AI Mode, Google’s chat-style search
- ChatGPT, Perplexity and Gemini, which more people use to ask “who’s the best X near me?”
Here’s the important part. AI tools pick their answers from websites that already do the SEO basics well. A 2026 study of nearly 40,000 AI answers found that half of all sources cited were the businesses’ own websites, and about a quarter were directories and review sites (Continuum, Sept 2026).
So good SEO now does two jobs at once. Read more in our guide to getting recommended by ChatGPT and Google AI.
What Google actually looks for
Google uses hundreds of signals, but for a normal business they boil down to five questions:
- Does this page answer the question? If someone searches “how much is a new roof in Cork”, the page should say how much, early and clearly.
- Is this business real and experienced? Google calls this E-E-A-T: Experience, Expertise, Authoritativeness and Trustworthiness. Real photos, real names, real reviews and real addresses all help.
- Do other people vouch for it? That means links from other sites, mentions and reviews.
- Is the website pleasant to use? Fast, works on a phone, no annoying pop-ups.
- Is it close by and relevant? This matters most for local searches.
Notice what’s not on the list: stuffing keywords, buying hundreds of links, or publishing 50 AI-written blog posts a week. Google’s 2026 core and spam updates hit exactly those tactics hard. We cover them in our 2026 Google updates explained.
SEO vs Google Ads: what’s the difference?
| SEO | Google Ads | |
|---|---|---|
| Cost | Monthly work, but no cost per click | You pay every time someone clicks |
| Speed | 3–6 months to build | Results from day one |
| When you stop | Rankings fade slowly | Traffic stops immediately |
| Trust | Many people skip ads and click normal results | Labelled “Sponsored” |
Most businesses do best with both: ads for quick wins, SEO for long-term, lower-cost leads.

7 SEO steps any Irish business can do this week
- Claim and fill in your Google Business Profile. Add every service, your opening hours and at least 10 real photos.
- Ask your last 10 happy customers for a Google review. Send them a direct link.
- Give every service its own page. “Services” as one page is not enough. Make “Kitchen Fitting”, “Bathroom Renovation” and so on separate pages.
- Write your page titles like a customer would search. “Electrician in Swords | Same-Day Callouts | Murphy Electrical” beats “Home”.
- Add an FAQ to each service page. Use the questions customers really ask you on the phone.
- Check your site on your phone. If it’s slow or fiddly for you, it’s slow for Google too.
- Set up Google Search Console. It’s free and shows what people search to find you.

What does SEO stand for?

Can I do SEO myself?
Yes. Many of the most important steps, like your Google Business Profile, reviews and clear service pages, are free and need no technical skill. Bring in help for technical fixes, content at scale or link building.

Most small and medium businesses pay €500 to €3,000 plus VAT per month. See our full SEO pricing guide for Ireland.
