Domain Authority Checker

Moz Domain Authority (DA) is a predictive search engine ranking score from 0-100. Higher DA means higher potential to rank. It is not a Google ranking factor, but it is heavily correlated with ranking power because it measures the factors Google actually uses: backlinks, referring domains, content quality, and brand strength.

Moz Domain Authority measures overall domain strength including backlinks, site age, content quality, and brand mentions. Majestic Trust Flow measures the quality and trustworthiness of your backlinks. Links from .gov, .edu, or industry news sites are high-trust; links from spammy directories are low-trust. A good link profile balances both: high DA and high Trust Flow.

A healthy dofollow ratio varies by industry, but a general target is 70-90% dofollow links. Nofollow links still drive traffic and signal relevance, but dofollow links pass link authority. If your profile has more than 30% nofollow links, it may indicate excessive paid or guest links that Google could penalize.

For competitive analysis, check key competitors monthly. For tracking your own sites, check quarterly, unless you are doing active link building, in which case check monthly after campaigns. Authority scores do not change quickly because they reflect historical link data, not immediate updates.
