"Domain Authority" is a marketing metric. It was invented by Moz, copied (with name variations) by Ahrefs, Semrush, and a dozen others, and Google has stated multiple times that they don't use anything called domain authority internally. So why care about it?
Because it's a useful relative benchmark. If you're at DA 22 and your competitor is at DA 78, you're not going to outrank them on their core keyword by writing better titles. You need to either pick different keywords, build link equity over time, or accept that you'll lose head-to-head and compete on the long tail. Knowing the gap helps you make that call.
Two warnings. First: don't optimize for DA. It's a downstream metric. Optimizing for DA directly leads to bad link-building decisions and eventually to penalties. Optimize for the things that incidentally raise DA — high-quality content people actually want to reference, technical correctness, and time. Second: ignore short-term DA fluctuations. The score recalculates monthly based on backlink crawl data, and individual months are noisy. Look at the 3- to 6-month trend.
