GSC data different with domain property vs URL prefix?

The title states that there is a disparity in data between the two properties - one being a verified domain and the other a URL prefix added property. There is a substantial difference of 4,000 vs 10,000 impressions over the same time frame. What could be causing this gap and which data set should be considered more reliable?

The difference in Google Search Console (GSC) data between a verified domain property and a URL prefix property could be attributed to several factors.

  • Crawling and Indexing: GSC might be crawling and indexing the domain property more effectively than the URL prefix property. This could be due to issues with the URL prefix property’s robots.txt file, sitemaps, or other technical factors that hinder crawlability.
  • Data Aggregation: The domain property aggregates data from all subdomains and URL prefixes, while the URL prefix property only shows data for that specific prefix. This can lead to discrepancies, especially if the URL prefix is used for a specific campaign or section of the website.
  • Verification Method: The verification method used for each property can impact data accuracy. Domain verification is generally considered more reliable than URL prefix verification.

To determine which data set is more reliable, consider the following:

  • Website Structure: If the website has a complex structure with multiple subdomains or URL prefixes, the domain property data might be more comprehensive and accurate.
  • Traffic Sources: Analyze traffic sources for both properties. If the URL prefix property is used for a specific campaign or section of the website, its data might be more relevant for that specific purpose.
  • Data Consistency: Compare the data for both properties over a longer period. If there are significant discrepancies, investigate potential reasons for the differences.

Ultimately, the most reliable data set depends on your specific needs and website structure. It’s recommended to analyze both data sets carefully and consider the factors mentioned above to make informed decisions based on your specific goals.
