Frequently Asked Questions
Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). DA scores range from 1 to 100, with higher scores corresponding to greater ability to rank.
DA is a relative metric. A DA of 50 is excellent for a new or small website. Compare your DA against direct competitors in the same niche rather than against large sites like Wikipedia (DA 95+). Aim to be higher than your competitors.
Key factors include: earning high-quality backlinks from reputable sites, creating link-worthy content, removing toxic backlinks (using Google Disavow), improving on-page SEO, increasing overall site content quality, and reducing spam score.
Domain Authority is a proprietary metric owned by Moz. Fetching it requires an API key from Moz's Link Explorer API (paid plans), and the request must go through a server to keep the API key secret. We're working on integrating this.
