Sistrix Visibility Index
Sistrix measures a domain's rankings weekly for hundreds of thousands of keywords and weights them by search volume and position. The result is a single index value. Advantages: Historical data since 2008, comparability between domains, detection of Google update impacts.
Alternatives
Searchmetrics SEO Visibility: Similar principle, different keyword basis. Semrush Visibility Index: Integrated into the Semrush suite. Ahrefs Traffic Value: Estimates the monetary value of organic traffic.
Limitations
The visibility index is based on a defined keyword set. Niche websites with very specific keywords can have a low index even though they rank well for their keywords. The index measures classic Google visibility, not AI visibility. Geo-monitoring requires supplementary tools.
