What is the referral 127.0.0.1:8888/orange.html in Google Analytics?

Out of the sudden, I started seeing the referral 127.0.0.1:8888/orange.html in several of the Google Analytics accounts I manage, which was weird because that is the address assign to a localhost.

Then I dig a bit into this traffic and I found that all of it had the service provider google llc, digging a bit more, I found that the network domain had information like googleusercontet.com and googlebot.com and both domains are associated with Google.

This led me to believe that this strange traffic comes from a Google index/cache bot, which is not beneficial to your Analytics at all.

What is Google LLC?

Doing a bit of research I found that Google LLC is the new official name used by Google since September of 2017 (previously Google Inc.), so it makes sense that a Googlebot uses this service provider.

But, why is it showing in your reports?

In general, Google Analytics does pretty good detecting well-behaved bots, like the ones that index your pages. However, this time it looks that the bot was not correctly tagged perhaps because of the new change or just a simple mistake.

It is worth mention that even if most of the traffic shows with the referral 127.0.0.1:8888/orange.html, some of it shows as (direct).

How to stop and remove traffic from "127.0.0.1:8888/orange.html" and "google llc"?

Even if the bot has good intentions, it doesn't add any value to your Analytics quite the contrary! So it is important to filter it to keep the integrity of your data.

Update: Previously I suggested filtering the referral 127.0.0.1:8888. After doing more research I noticed that his traffic shows also as (direct) and other sources source so instead, we will create an ISP organization filter for google llc, that will take care of all.

Before creating any filter in your analytics it is best practice to always have an unfiltered view. I've prepared step by step instructions with everything you need to get rid of this bot traffic:
