You know what? I didn’t plan to use both. I just wanted answers. Why did people leave my site? Which pages worked? What broke on mobile? So I turned on Google Analytics (GA4) for the numbers, and Microsoft Clarity for the “show me what actually happened” part.
Turns out, they feel like two sides of the same coin. And sometimes they argue, which is funny and annoying at the same time.
For teams focused on recurring-revenue metrics, I’ve seen Scout Analytics slot in nicely alongside GA4 and Clarity. If you’d like a deeper, blow-by-blow rundown of how Clarity stacks up against GA4, you can skim my full comparison here.
My Setup (Nothing Fancy)
- Site 1: a small Shopify store.
- Site 2: a WordPress blog.
- Site 3: a simple SaaS landing page.
I installed GA4 through Google Tag Manager. If you’re weighing those two tools against each other before you install anything, this real-world GTM vs Google Analytics test might save you a headache.
That part took me a couple hours the first time, since I had to set up events and mark a few conversions. Clarity was faster. Ten to fifteen minutes, and I had heatmaps and session replays. I also linked Clarity with GA (step-by-step guide), so I could jump from a GA report to the matching Clarity sessions. That link saved me on a busy Monday.
Where GA4 Shines: The “How Many, From Where, And Did They Buy?” Tool
GA4 gives me the big picture. Traffic by channel. Conversions. Revenue. Paths. It also lets me export to BigQuery, which I use when I want deeper stuff later.
Real example: on my Shopify store, I saw a weird dip in sales after my Instagram ads. GA4 showed me this:
- Traffic from Instagram: up 42%
- Add-to-cart: flat
- Conversions: down 18%
So more people came, but fewer bought. Huh.
This is where GA4 did its job. It showed the “what.” Not the “why.”
Where Clarity Shines: The “Wait, What Did They Just Do?” Tool
Clarity shows me heatmaps, scroll depth, and actual session replays. It flags rage clicks, dead clicks, and “quick backs” (when users bounce fast). It also hides sensitive text by default, which makes me breathe easier. Those quick backs remind me that visitors make snap judgments online, almost like they're playing a real-life version of Hot or Not. The linked breakdown explores how the app’s instant rating mechanics drive engagement and gives marketers fresh insight into why first impressions on any page matter so much.
For another quick example, think about niche, location-based directories that cater to a wellness-meets-nightlife crowd; these pages rely on instant credibility, or users vanish. I recently audited one such site—check out my notes on Rubmaps Coachella, where I break down the design tweaks, trust badges, and call-to-action placements that lifted time on page and boosted bookings for a notoriously bounce-prone audience.
If you’re thinking about an open-source alternative, I put PostHog through the same paces and wrote up a hands-on PostHog vs Google Analytics comparison.
For that same Instagram issue, Clarity replays showed mobile users tapping the “Pay Now” button over and over. Rage clicks. I felt the stress through the screen. The button looked active, but a tiny script blocked it if the street field had a comma. Yes, a comma. Who knew.
I fixed the rule and changed the error message to plain language. Next week, mobile checkout conversions went up 23%. GA4 showed the win. Clarity told me why it happened.
Real Stories From My Screen
1) The Checkout Button That Wasn’t Broken (But It Was)
- Problem: People kept rage-clicking “Pay Now” on iPhone.
- Clarity: Replays showed a “floating” error message under the keyboard. No one could see it.
- Fix: Moved the error to the top and made the button shake when the form wasn’t complete.
- Result: Cart abandonment dropped from 68% to 54% in 10 days. GA4 confirmed it.
2) The CTA That Lived Too Far Down
- Blog post about back pain. Strong traffic from Google.
- GA4: Average time on page was fine, but few clicked my “Get the guide” button.
- Clarity heatmap: Only 35% of users reached the button. It sat too low on mobile.
- Fix: Moved the button under the second paragraph.
- Result: Click-through rate jumped from 1.1% to 3.8%. Small change, big mood.
3) The Form That Said “No” Without Saying It
- Newsletter form on the SaaS landing page.
- GA4 funnel: Drop-off at the email step, especially on Safari.
- Clarity: Dead clicks on the submit button. Replays showed the error badge rendering off-canvas. You couldn’t see it, so people kept pressing submit and gave up.
- Fix: Better inline error, and a simple “Email looks wrong” tooltip.
- Result: Form completion rose 19%. I did a tiny happy dance.
Speed, Privacy, And All That Good Stuff
I was worried about speed. Clarity felt light on my sites. I didn’t see a hit on Core Web Vitals. GA4 was fine too.
Both tools handle privacy controls. Clarity masks text by default. GA4 has consent mode and IP controls. I had to tune cookie banners, but that’s life now.
For enterprise stacks, some teams ask whether Adobe Analytics 360 earns its hefty price tag; I put that to the test in this GA360 vs Adobe Analytics deep dive.
One note: Clarity keeps data for about a year. GA4 also stores plenty, and I like that I can send raw data to BigQuery when I need history.
The Learning Curve (I’ll Be Real)
- GA4: Steep at first. The “Explorations” are strong, but they can confuse folks. I still need coffee before using them.
- Clarity: Easy. Open, filter, watch a few sessions, learn fast. The weekly email from Clarity has quick wins. I like those.
What I Use Each One For
-
GA4:
- Traffic and channel performance
- Conversions and revenue
- Funnels and attribution
- Ad spend checks (was it worth it?)
-
Clarity:
- Heatmaps and scroll maps
- Session replays (the gold)
- Rage clicks, dead clicks, quick backs
- UX fixes, especially on mobile
A Little Black Friday Note
During Black Friday, GA4 told me my email list sent the most buyers. No shock there. But Clarity showed me something odd: shoppers on older Android phones kept hitting the coupon field, then bouncing. The field looked clickable before the page fully loaded; it then jumped down and lost focus. Tiny detail, big pain. I added a loading state and a “Paste code” hint. The next day, coupon use went up 12%, and checkout speed got smoother.
So, Which One Would I Pick?
Honestly? I use both. They do different jobs.
- If I had only a blog and no ads, I could live with Clarity alone for a while. It helps me fix layout issues and keep readers moving.
- If I’m running ads or tracking sales, GA4 is not optional. It’s my scoreboard.
- The magic happens when I connect them: GA4 shows me where to look; Clarity shows me what to fix. For a deeper dive on squeezing more joint value out of the pair, check out this quick primer.
If you’re still torn between sticking with GA4 or making the leap to Adobe Analytics, here’s my unfiltered story on that exact choice.
Final Word
If numbers feel cold, Clarity makes them human. If stories feel fuzzy, GA4 keeps them honest. I need both. And you know what? When I watch a few sessions and then check the reports, I feel calm. Well, calmer. That’s worth a lot on a busy week.
