Digital marketing basics
Every digital marketing channel explained simply, with what it costs in Ireland and a simple rule for choosing the right mix for your business.
Short answer
Digital marketing is any way of getting customers online, through Google, AI search tools, social media, email and your website. Unlike a newspaper ad or a billboard, you can target exactly who sees it and track exactly what it brings in. For most Irish small businesses, the best mix is SEO plus Google Business Profile for steady leads, paid ads for speed, and email or social to keep customers coming back.
Key takeaways
- Your website is the shop, and marketing brings people to the door
- SEO and Google Business Profile are the foundation for most local firms
- Ads are fast but stop when you stop paying
- AI search is now a channel of its own
- Measure enquiries and cost per enquiry

Think of it like a shop on a busy street
Your website is the shop. Digital marketing is everything that gets people to walk in:
SEO
The shop being on the main street, where people already walk past.
Google Ads
Paying for a big sign at the start of the street.
Social media
Chatting with people at the market, so they know your name.
Phoning past customers about this week’s offer.
AI search
The friendly local who gets asked “where should I go?” and names you.
Your website
The shop itself. If it’s a mess, nothing else works.
A shop on the best street still fails if the shop itself is a mess. That’s why your website comes first.

Inbound vs outbound: the two kinds of marketing
- Outbound means you interrupt people: ads, cold emails, sponsored posts. It’s fast, but you pay for every result.
- Inbound means people come looking for you: SEO, helpful content, reviews, AI search. It’s slower to build, but each lead gets cheaper over time.
Most healthy businesses use outbound to fill the gap while inbound grows.
What changed in digital marketing in 2026
- AI answers are now a channel. People ask ChatGPT and Google AI Mode for recommendations. Being mentioned there is the new “word of mouth”. See how to get recommended by AI.
- Fewer clicks from Google. AI Overviews answer many questions on the results page. Your content has to be good enough to be quoted, not just clicked.
- Google rewards real businesses. Its 2026 updates favoured original content, real expertise and known brands over generic, mass-produced articles (2026 updates explained).
- Video everywhere. YouTube is the single most-cited website in Google’s AI Overviews. A two-minute “how much does X cost?” video can work harder than a blog post.
- Privacy changes. Cookie banners and tracking limits mean you need first-party data, such as your own email list, enquiry forms and call tracking.
How to choose the right mix (a simple rule)
Ask yourself three questions:
- Do people already search for what I sell? (For example “boiler service Dublin”.) If yes, start with SEO and Google Ads.
- Do people need to see it to want it? (Fashion, food, interiors, events.) If yes, lean on Instagram, TikTok and Meta ads.
- Do customers come back? (Salons, gyms, cafés, B2B.) If yes, build an email or WhatsApp list from day one.
For most Irish service businesses the answer to question 1 is yes. That’s why SEO and Google Business Profile are almost always the foundation.
How to measure if it’s working
Ignore “likes” and “impressions” on their own. Track:
- Enquiries: calls, forms, WhatsApp messages, emails
- Cost per enquiry: what you spent divided by enquiries
- Which channel each customer came from. Simply ask “How did you find us?” on every call.
Set up Google Analytics 4 and Google Search Console (both free), plus call tracking if the phone is your main lead source.
