Overview

Moz (originally SEOMoz) was founded in 2004 by Rand Fishkin and Gillian Muessig in Seattle, United States. As an SEO tool platform, Moz created the widely referenced Domain Authority (DA) and Page Authority (PA) 0-100 metrics and lets users view them instantly on any page or search result through the free MozBar browser extension.

Moz is also known for SEO education: its Beginner's Guide to SEO is one of the most widely read SEO guides on the internet, and the Moz Blog and Whiteboard Friday series have long provided high-quality community content. On the product side, Moz Pro covers keyword research, backlink analysis, site audit, and rank tracking, Moz Local targets local merchants, and Moz API supports programmatic data access. For beginners, see SEO beginner's guide.

Key Strengths
