The History and Evolution of Moz Extension

Moz, originally known as SEOmoz, was founded in 2004 as a blog and online community where SEO professionals could share ideas and insights. Over time, Moz evolved into a software company, developing a range of SEO tools, including the Moz Extension. The extension has been continuously updated and improved over the years, adding new features and metrics to help users stay ahead of the curve in the ever-changing world of SEO.
