What is "when the same default tracking code is installed on pages with different domains?

Having the same default tracking code on pages with different domains can lead to several issues and inaccurate data in your analytics. Here's a breakdown:

• Data Pollution: The primary problem is <a href="https://www.wikiwhat.page/kavramlar/data%20pollution">data pollution</a>. All data collected from these different domains will be aggregated under a single view in your analytics platform. This means you won't be able to accurately distinguish user behavior on each domain, making it difficult to understand which sites are performing well, which marketing campaigns are driving traffic to specific sites, or the overall user journey across domains.

• Inaccurate Reporting: Key metrics like bounce rate, session duration, and conversions will be skewed. Because all activity is lumped together, you won't have a true picture of how users interact with each individual domain. This makes it extremely difficult to perform meaningful <a href="https://www.wikiwhat.page/kavramlar/data%20analysis">data analysis</a> and gain actionable insights.

• Referral Issues: Cross-domain tracking becomes severely compromised. Instead of properly attributing traffic between domains, your analytics might report internal referrals from your own domains, further muddying your data and misrepresenting the source of traffic. This throws off your <a href="https://www.wikiwhat.page/kavramlar/referral%20tracking">referral tracking</a> and obscures the true origin of conversions.

• Audience Segmentation Problems: You can't properly segment your audience based on domain. You won't be able to create audience segments for users who visited only a specific domain, hindering your ability to target them with relevant content or marketing campaigns. Effective <a href="https://www.wikiwhat.page/kavramlar/audience%20segmentation">audience segmentation</a> requires distinct data sets.

• Cookie Conflicts (Potentially): While less common with modern tracking implementations, there could be potential cookie conflicts depending on how cookies are configured. This is especially true if cookies are set at the top-level domain without careful consideration of cross-domain implications.

Solution: The proper solution involves implementing <a href="https://www.wikiwhat.page/kavramlar/cross-domain%20tracking">cross-domain tracking</a>, or using separate tracking IDs/properties for each domain. Cross-domain tracking allows your analytics platform to recognize user sessions as continuous across multiple domains, providing a more accurate view of the user journey. If the domains are entirely unrelated, using separate tracking properties is generally the preferred method.
