NexaMetrics

I started NexaMetrics to help brands and agencies fix their tracking setups. No more confusion, guessing, or complicated setups, just clear and accurate data.

Since I started, I worked with over 200 advertisers and agencies, fixing their GA4, GTM, Meta Pixel, and server-side tracking issues. My main goal is simple:

Make sure you know exactly where your results come from, so you don't lose money because of bad data.

Here's what we've done so far:

- Finished 1,250+ tracking setups for websites, funnels, and apps.

- Worked with 200+ teams in eCommerce, Lead Generation, SaaS, and digital agencies.

- Helped track more than $100M in advertising spend.

- Set up tracking tools like GA4, Looker Studio, Meta Conversion API, and Server-Side GTM.

- Fixed common problems like duplicate events, missing conversions, and messy GA4 setups.

- Built tracking systems that respect privacy and follow GDPR rules.

- I enjoy working with marketers, founders, and media buyers who want to grow their business and trust their data.

My main principles:

↳ Keep everything easy and clear.

↳ Fix the real problems, don't just add more tools.

↳ Make tracking setups simple enough for everyone on your team to use.

If you’re tired of reports you can’t trust, missing conversions, or not knowing what works in your funnel, NexaMetrics can help.

We help you track better, grow faster, and trust your data completely.

Stop ignoring the 'Remove from Cart' event.
It can be your Goldmine

Most eCommerce brands miss it.
Even many tracking setups skip it.

I worked with an online fashion store.
They tracked purchases and add-to-cart etc.
But they didn’t track remove_from_cart.

Everything looked fine.
But sales were not growing up as expected.

What I Found

After I added remove_from_cart event, the picture became clear:

◾ One premium product had the highest add-to-cart rate.
◾ But it also had the highest remove-from-cart rate.

Why?
The shipping fee was added after cart.
Customers felt tricked → they dropped it.

That was invisible until we tracked remove_from_cart.

The Cost of This Mistake

⨭ Thousands spent retargeting the wrong way.
⨭ No clue about friction in the buying journey.
⨭ Missed chance to optimize pricing and offers.

By acting on remove_from_cart insights, we:

⨭ Fixed shipping fee transparency
⨭ Created better retargeting audiences
⨭ Offered installment plans for high-ticket items

Sales went up without increasing ad spend.

Why remove_from_cart matters even more

⨭ They were this close.
Something stopped them. Maybe price. Maybe doubt. Maybe life got in the way.

These are perfect retargeting opportunities.

⨭ It shows why people don’t buy.
If a product gets removed often, something’s off.

Fix it → conversions go up. Simple.

⨭ It opens the door to better offers.
Removed a high-ticket item?

Hit them with a payment plan or time-limited offer.
Close the gap.

⨭ It feeds smarter recommendations.
They didn’t want that product… maybe they’ll like a similar one.
This is where AI and human logic can tag team.

✅ Lesson:

Don’t just track what people buy.
Track what they almost bought.

Remove_from_cart tells you:
↳ Where buyers hesitate
↳ Which products need attention
↳ How to craft better offers

Marketers love data.

But here’s the harsh truth:
Most of the data you see today is incomplete.

Cookies get blocked.
Pixels get stopped.
iOS updates limit what you track.

Result? data looks broken, Campaigns get less credit. Ad platforms miss conversions.

No one think about how their tracking survives in the future.

Client-side tracking? It’s losing power every day.

Server-side tracking?

It sends data directly from your server to platforms like Google, Meta, TikTok. (No browser issues. No ad blockers. Higher accuracy.)

Without it, you keep running blind. With it, you future-proof your ads.

Smart advertisers know: data quality > ad creative.

Now, let’s be clear:

Will server-side tracking bring you more sales immediately?

Most probably not.

You won’t see results in the first week, but trust me, they will come.

In about 3 months of feeding better data to the ad platforms, you could see something like this:

↳ Customer acquisition costs drop by -20%
↳ Same ad budget = +20% more customers

This is significant, but it requires patience.
You’re essentially training the ad algorithms to work better for you.

So, how do you move forward?

⨭ Start with a server-side container in GTM
⨭ Send conversion events through a trusted server endpoint
⨭ Use tools like Stape, TAGGRS, or Google Cloud for setup
⨭ Compare uplift vs. client-side only tracking

Client-side tells you some of the truth.
Server-side gives you the real picture.
