Seeing LeadsGo.io Spam in Your GA4? Here’s How to Block It

Just opened GA4 and saw leadsgo.io in your referral report?

Yeah, me too.

It’s not a real visitor. It’s not a potential lead. Leadsgo.io is the latest clown car of referral spam driving straight through your analytics, and it’s completely useless.

They’re not actually visiting your site. They’re pinging the GA4 measurement protocol directly to get their name in your reports, hoping you’ll get curious and visit their domain. Don’t.

Why Spam Referral Traffic Matters

• It inflates your traffic. Makes you look more popular than you are, which is a lie.
• It wrecks your metrics. All this junk traffic has a 100% bounce rate and 0s session duration, tanking your engagement stats and making real analysis a nightmare.
• It wastes your time. You should be analyzing real user behavior, not filtering out ghost traffic.

The Fix (No Fluff)

GA4’s built-in bot filtering is clearly not catching this. So you have to do it yourself. It takes two minutes.

1. Go to Admin.
2. Under Data collection and modification, click Data Streams.
3. Click on your web stream.
4. Under Google tag, click Configure tag settings.
5. Click Show all, then click List unwanted referrals.
6. Under Match type, select Referral domain contains.
7. Under Domain, type leadsgo.io.
8. Click Add condition.
9. Click Save.

That’s it.

This blocks it from showing up from now on. It won’t clean your historical data. For that, you’ll have to build a segment in your Exploration reports to exclude Referral source = leadsgo.io when you’re looking at past performance. Annoying, but necessary.

It’s 2025 and we’re still playing whack-a-mole with referral spam. You’d think Google could get ahead of this, but apparently not.

Alright, rant over. Go fix your data.

P.S: I’m irritated that I had to create this post and give them even more exposure.
