SA – SERP Affinity (SEOZoom)
SERP Affinity is a proprietary SEOZoom value that indicates as a percentage how similar the examined keyword is considered to the Main Keyword by search engines.
The value is calculated by an SEOZoom algorithm that analyzes URLs and organic search results.
To make a simplification, the SA compares the keyword under analysis with the Main Keyword and indicates as a percentage how many TOP10 ranked results are in common between the two SERPs.
