Timeline (last 90 days)
Zyppy's analysis of about 400 websites found that 92.9% of winning sites had proprietary assets, while among losing sites this proportion was only 57.1%.
The Zyppy study examined the differences in characteristics between winners and losers over the previous 12 months (including the March 2026 core update), with data from Ahrefs traffic metrics, and used Spearman correlation coefficients to quantify the relationship between site characteristics and traffic changes.
Among the five predictive characteristics, proprietary assets ranked third, with the top two being "offers a product or service" and "allows users to complete a task," followed by "focused vertical topic" and "strong brand."
The Zyppy study reveals correlation, not causation, between site characteristics and traffic changes, i.e., having proprietary assets does not necessarily mean surviving a core update.
