TZA – Topical Zoom Authority (SEOZoom)

Topical Zoom Authority is a proprietary SEOZoom metric that helps to quickly evaluate sites within individual niches.

Using this value, set on a logarithmic scale from 0 to 100, it is possible to identify the best site for each online industry and find out the level of authority of each site in each vertical niche.

Through TZA, SEOZoom is able to precisely rank each site within a topic for which it has keywords ranked on Google, effectively creating a new ranking that goes beyond overall domain value and keyword search volumes.
