AI for Facebook and Google Advertising: Guide for Irish Business Owners
Irish small business owners spend millions of euros on Facebook and Google ads every year — and a large proportion of that spend is wasted on ads with poor copy, wrong targeting, or no structure. AI tools do not replace the platforms, but they dramatically improve what you put into them. This guide shows you how.
Why Most Small Business Ads Underperform
The two most common reasons small Irish businesses waste ad budget are: poor copy (the words in the ad are generic and give people no reason to click) and wrong targeting (the ad reaches people who will never buy). AI helps with the first problem directly. It also helps with the second by giving you a structured way to think about who your audience actually is.
Writing Facebook Ad Copy with AI
Facebook ads work best when they are specific, local, and address a real pain point. Generic ads (“Best electrician in Dublin — call now!”) get scrolled past. Specific ads that speak to a situation (“Fuse board tripping repeatedly? Here's why it happens and how we fix it in one visit”) stop people mid-scroll.
Use this prompt structure with ChatGPT:
“Write three Facebook ad variations for a home insulation company targeting homeowners in Co. Meath and Co. Louth. The service is attic insulation with SEAI grant support. One ad should focus on the financial saving (energy bills), one on the SEAI grant (free or reduced cost), and one on comfort (warmer home this winter). Each ad: headline, one sentence body text, and a call to action. Keep each version to 50 words maximum.”
You now have three angles to test. Each speaks to a different motivation — saving money, getting a grant, or feeling comfortable. Different homeowners will respond to different messages. Running all three with a small daily budget (€5-€10 each) and checking which gets more clicks after a week gives you real data instead of guesswork.
Real Example
A painting and decorating business in Cork was running one Facebook ad with generic copy. They used ChatGPT to generate five variations focused on different triggers — spring refresh, tidy up before selling, protect external walls from Irish weather, free quotes with next-day availability. The winning ad (based on a two-week test) had four times the click-through rate of the original.
Writing Google Search Ad Copy with AI
Google search ads appear when someone types a specific query. The ad copy must match what the person is looking for and give them a strong reason to click your result instead of the one above or below it.
Google Ads has specific character limits: headlines are 30 characters maximum (you provide up to 15), and descriptions are 90 characters maximum (you provide up to 4). Ask ChatGPT to work within these constraints:
“Write Google search ad copy for a plumbing company based in Galway. Target keyword: emergency plumber Galway. Write 5 headlines (max 30 characters each) and 3 descriptions (max 90 characters each). Focus on speed of response, 24/7 availability, and free callout within the Galway area.”
ChatGPT will produce copy within the character limits. You can then select the best combinations and test them in your Google Ads account. Responsive search ads (RSAs) allow you to enter multiple headlines and descriptions and let Google automatically test combinations — AI-generated variety fits perfectly into this format.
Real Example
An IT support company in Sandyford was spending €800/month on Google Ads with mediocre results. Their ad copy was identical to competitors. Using Claude to generate differentiated headlines focused on their specific USPs (15-minute response SLA, fixed monthly fee, local to south Dublin), combined with better negative keywords, their cost per lead dropped by 35% within six weeks.
Using AI to Define Your Target Audience
Facebook's targeting options can be overwhelming. AI helps you think clearly about who you are actually trying to reach before you get into the platform.
“I run a domestic cleaning service in Dublin 6, Dublin 6W, and Dublin 8. My best clients are professional couples or families where both partners work full time and have children under 12. Help me identify Facebook targeting options that would reach this audience. What interests, demographics, and behaviours should I select?”
The response will give you a structured targeting framework — age ranges, household income proxies (home ownership, car ownership), interests (school-age children, home decor, local community groups), and behaviours. You still have to implement this in Meta Ads Manager, but having a clear targeting brief before you open the platform saves hours of experimentation.
Using AI to Analyse What Is Working
If you are running ads and have performance data — click-through rates, cost per click, conversion rates — you can paste this into ChatGPT and ask it to help you interpret what it means and suggest improvements.
“I have three Facebook ads running for my window cleaning business. Ad A: CTR 0.8%, cost per click €0.45. Ad B: CTR 0.3%, cost per click €1.20. Ad C: CTR 1.6%, cost per click €0.22. Which ad is performing best and why might that be? What should I do with the underperforming ads?”
ChatGPT will explain what the numbers mean, identify Ad C as the clear winner on cost efficiency, and suggest pausing Ad B and iterating on Ad A. This is basic media buying analysis that agencies charge for — you can do it yourself in three minutes.
Automating Ad Workflows with Make.com
For more advanced users, Make.com can connect your advertising platforms with other tools. For example: automatically sending a WhatsApp message to leads who fill in a Facebook Lead Ad form, or alerting you when a Google Ad campaign exceeds a daily budget threshold. These automations require some setup time but run indefinitely once built.
Real Example
A Kildare-based landscaping company set up a Make.com automation that sends an automatic WhatsApp message to every Facebook Lead Ad submission within two minutes. The message, written with ChatGPT, acknowledges the enquiry, confirms they will be in touch within 24 hours, and includes a link to view their recent work. Lead conversion improved because response time dropped from hours to minutes.
A Practical Starting Point
If you are currently running ads with one version of copy that you have not changed in months — spend 20 minutes with ChatGPT generating five new variations. Pick two that are meaningfully different from each other and test them. The improvement in performance will be noticeable within two weeks.
If you are not running ads yet — use AI to write your first batch of copy and think through your targeting before you spend a cent. Going into the platform with a plan is far more effective than learning by spending.
