We regularly meet Irish businesses that run Facebook and Instagram ads with a Meta Pixel on their site, but no GA4 set up at all. Or GA4 is installed, but nobody has looked at it since the day it went live.
The Meta Pixel is useful. But on its own, it only tells you part of the story. Google Analytics 4 is what shows you the whole picture, so you can make decisions about where your time and money go.
What GA4 actually does for your business
GA4 records what happens on your website, whoever sent the visitor. That includes:
- Organic search: people who found you on Google
- Paid search: clicks from Google Ads
- Paid social: clicks from Meta, TikTok or LinkedIn ads
- Organic social: links from your own posts
- Email: newsletters and automated emails
- Referral and direct: other websites linking to you, and people typing your address
All of those sit in one place, measured the same way. That is the part a single ad platform can never give you.
User journeys
GA4 shows the path people take. Someone might land on a blog post from Google, come back a week later from an Instagram ad, then return directly and book. GA4 lets you see those patterns across channels.
Which pages bring enquiries
Once your key events are set up (form submissions, bookings, calls, purchases), GA4 tells you which pages and which channels lead to them. That is how you work out which services to promote, which pages to improve and which content is worth writing more of.
Why a Meta Pixel on its own is not enough
The Meta Pixel is built to help Meta’s ad system. It does that job well, and we rely on it for the Meta campaigns we run through our media buying work. But it has limits.
It only reports Meta’s view
Meta Ads Manager reports on people who saw or clicked a Meta ad. It has no view of your Google Ads, your SEO or your email list. You cannot compare channels from inside Ads Manager.
It uses its own attribution
Meta can count a conversion if someone clicked an ad, or in some settings only viewed one, within a set window before they converted. Google Ads does something similar for its own clicks. If you add up what each platform claims, the total is often more than the sales you actually made.
GA4 applies one set of rules to every channel, so you get a fairer comparison.
It misses people who never saw an ad
Plenty of your best customers never see an ad at all. They search your name, follow a link from a local directory or come from a friend’s recommendation. The pixel can track them on your site, but Meta’s reporting is about ad performance, not your whole audience.
Use GA4 and the Meta Pixel together
This is not an either or decision. Each tool does a different job.
- The Meta Pixel (ideally with the Conversions API) feeds Meta’s algorithm so it can find more people like your customers.
- GA4 is your independent record of what every channel delivers.
On campaigns like Darwin’s Tavern, Meta reporting helps us optimise the ads themselves, while site analytics helps us see how paid social sits alongside everything else.
Both need consent handled properly. Our guide to Consent Mode v2 and GA4 setup covers how to do that without losing useful data.
Link Google Search Console to GA4
Search Console shows the searches people used to find you on Google, and which pages appeared. Linking it to GA4 brings that data into your analytics, so you can see search queries and landing pages next to what visitors did afterwards.
It is free, it takes a few minutes, and it is one of the most useful things you can do for your SEO reporting.
Simple GA4 reports to check every month
You do not need to become an analyst. These few reports cover most of what an owner needs.
- Traffic acquisition: sessions and key events by channel. Which channels are growing, and which actually bring leads?
- Landing pages: the pages people arrive on first. Which ones bring traffic, and which ones lead to enquiries?
- Key events: total enquiries, bookings or sales this month compared with last month and the same month last year.
- Search Console queries: what people searched before finding you. Are you showing up for the services you want to sell?
- Devices: the split between mobile and desktop. If most visitors are on phones, your mobile experience matters most.
Fifteen minutes a month with these reports will tell you more than any single ad dashboard.
One setting to change today
By default, GA4 keeps detailed event data for only two months. In Admin, under data retention, you can raise it to 14 months on a standard property. That lets you compare this year with last year in your detailed reports.
Where to start
Check that GA4 is installed, that your enquiries or sales are marked as key events, and that Search Console is linked. If any of those are missing, that is your first job.

FAQ
Is GA4 free?
Yes. The standard version of Google Analytics 4 is free and is more than enough for most Irish small and medium businesses.
Why do GA4 and Meta show different numbers?
They count differently. Meta includes conversions after ad views and uses its own time windows. GA4 credits the channel based on the visits it recorded. Neither is wrong. They answer different questions.
Do I still need the Meta Pixel if I have GA4?
If you run Meta ads, yes. The pixel is what lets Meta optimise your campaigns and build audiences.
