This support article explains how to filter 'referrer spam' in Google Analytics and Leadfeeder so it won’t appear in the future. The reason it’s important to do this is at least two-fold: this fake traffic not only spoils your referral report in Leadfeeder, but also skews your metrics in Google Analytics.

But what happens if you’re only now getting round to setting this up and you already see some weird traffic sources in Leadfeeder, such as and

Here's the answer: 

Firstly If you want to see where traffic is coming from (and find referrer spam) you should search by "source” inside Leadfeeder. When you see a source that you’re not sure about, check our article of known spam referrers or quickly search online to check its validity.

Tip: make sure the time range you select is at least 30 days.

What next?

If you identify spam referrers, then add these to your exclude filter pattern in Google Analytics (as our article explains), so data from these sources doesn’t show in Google Analytics and Leadfeeder.

Secondly, by selecting these sources you can create a list of companies in Leadfeeder whose source is referrer spam. Go through this list and hide companies that are not relevant or interesting for you, such as Internet Service Providers (ISPs).

Tip: when you hide a company it doesn’t count towards your lead quota and you won’t see it ever again in Leadfeeder unless you un-hide it. So think twice before hiding legitimate companies.
