Definition
Host Trust is a metric developed by Babbar.tech that evaluates the reliability of a host (subdomain) by analyzing the quality of sites linking to it. Inspired by Majestic's Trust Flow concept, Babbar's Host Trust uses its own algorithm and crawl data to calculate a site's proximity to established trust sources. A high Host Trust indicates the site receives links from reputable and reliable sources. This metric is particularly relevant for the Francophone market as Babbar has excellent coverage of French-language websites. Host Trust is used alongside the Babbar Authority Score and Semantic Value to build a complete picture of domain quality.
Key Points
- Measures host trust based on the quality of its link sources
- French alternative to Majestic's Trust Flow with independent crawl data
- Complementary to Babbar Authority Score and Semantic Value
