The BLD Score™: A Data-Driven Framework for Directory Authority
Our rankings are generated by a proprietary 10-factor algorithm evaluating directories for the AI-first era of 2026. No pay-to-play, no hidden criteria—just transparent, data-driven benchmarks that define the industry gold standard.
The 10 Evaluation Vectors
Each factor is weighted based on its impact on local SEO success and AI discoverability. The radar chart below visualizes how we balance these priorities.
