How To Fix Redundant Hostnames In Google Analytics

Google Analytics is a powerful tool for tracking website traffic and user behavior. However, it can sometimes be difficult to get accurate data if you have multiple hostnames pointing to the same website. This can lead to duplicate data and confusion when trying to analyze your website’s performance.

What are Redundant Hostnames?

Redundant hostnames occur when there are multiple URLs that point to the same website. For example, if you have both and pointing to the same site, this can cause problems in Google Analytics.

Why are Redundant Hostnames a Problem?

When there are multiple hostnames pointing to the same website, it can be difficult for Google Analytics to accurately track user behavior. This is because each hostname will have its own unique tracking code, which means that data from different hostnames may not be combined properly.

How to Fix Redundant Hostnames in Google Analytics

Fortunately, there are a few ways to fix redundant hostnames in Google Analytics. The first step is to identify which hostnames are causing the problem. You can do this by looking at your website’s traffic sources and identifying any duplicate hostnames.

Option 1: Use Canonical URLs

One way to fix redundant hostnames is to use canonical URLs. A canonical URL is a special tag that tells Google Analytics which version of a page is the “official” version. By using canonical URLs, you can ensure that all traffic from different hostnames is directed to the same tracking code.

Option 2: Use Cross-Domain Tracking

Another way to fix redundant hostnames is to use cross-domain tracking. This involves setting up a special tracking code that allows Google Analytics to track user behavior across multiple domains. By using cross-domain tracking, you can ensure that all traffic from different hostnames is combined into a single report.

Option 3: Use the Hostname Filter

If you don’t want to use canonical URLs or cross-domain tracking, you can also use the hostname filter in Google Analytics. This allows you to exclude certain hostnames from your reports, which can help to reduce duplicate data.


Redundant hostnames can be a problem for website owners who want accurate data from their Google Analytics reports. However, there are several ways to fix this issue and ensure that your data is accurate and reliable. By using canonical URLs, cross-domain tracking, or the hostname filter, you can eliminate duplicate data and get a clear picture of how users are interacting with your website.
