What the Domain Authority Checker does
Domain Authority is the metric everyone quotes and half the industry misreads. This checker gives you the full context in one lookup: current Moz DA, how it has moved over four years, total linking domains, total backlinks, link propensity, and spam score. Bulk mode handles up to 10,000 domains with CSV or Excel export.
The 4-year trend is the part most DA tools omit and the part that matters most — a DA 35 site climbing beats a DA 50 site bleeding. I check DA constantly when vetting guest-post targets, valuing expired domains, and qualifying link prospects from the Backlink Gap Analyzer. For a second opinion that blends multiple signals, cross-check with the Website Authority Checker.
How to use it
- Enter a domain — or paste up to 10,000 for a bulk run.
- Read the current DA alongside the 4-year trend line, not in isolation.
- Check linking domains vs. total backlinks — a huge link count from few domains is a red flag.
- Export to CSV or Excel when qualifying link prospects or domain purchases at scale.
Domain Authority Checker FAQ
What is a good Domain Authority score?
DA is comparative, not absolute — a "good" score is one higher than the sites you compete with in the SERPs. As rough texture: under 20 is new or weak, 20–40 is established niche territory, 40–60 is strong, 60+ is major-publisher tier.
Is DA a Google ranking factor?
No — Google doesn’t use Moz’s DA. It’s a third-party prediction of ranking ability based on link data. It correlates well enough to be useful shorthand for comparing sites, which is how it should be used: comparison, not gospel.
Why does the 4-year DA trend matter?
Trajectory reveals what a snapshot hides: whether a site is earning links or losing them. For buying domains, swapping links, or picking guest-post targets, a rising mid-DA site is usually the better bet than a declining high-DA one.
