Schema.org has launched a new feature that provides aggregate statistics on the usage of its schema types across the internet. This initiative aims to give insights into how many domains are implementing specific structured data elements. The organization stated that this dataset will be updated monthly and presents data at the domain level, categorizing it into popularity ranges. This method reduces daily fluctuations while emphasizing significant trends in schema adoption, which can be beneficial for developers and researchers alike.
The usage statistics are derived from Google’s web crawling infrastructure, ensuring that the data reflects domain-level usage rather than individual pages. Therefore, if a schema term is used on multiple pages of a single domain, it is counted only once. Instead of providing precise numbers, which can vary frequently, the data is grouped into ranges, such as '10K - 100K' domains, to maintain stability and safeguard privacy.
For those interested in the raw data, it is accessible on GitHub in both JSON and CSV formats, updated monthly. Understanding the popularity of specific schema elements can influence development decisions, encouraging teams to adopt relevant schema implementations.
