Brownbook vs Manta

Brownbook is a global business listing directory where people can add listings, update details, and review businesses. Owners can claim listings to verify information and take control, enrich profiles with text, photos, and videos, and receive alerts about reviews. Brownbook also offers BLINX, a mobile-optimised business bio page with a short URL and QR code. The free business listing costs nothing. For bulk listing work, the Publisher API supports searching, inserting, editing, and deleting listings; it costs $0.10 a month, billed per listing per month, and requires a signed API agreement and an authorized OAuth key or token. Commercial users may not submit more than five listings for gain unless using the authorized API under a commercial agreement. Brownbook says listings can support search visibility and attract customers. The service is available on the web and through an API, and offers help pages and an email contact form.
