Website Authority Checker

Check the authority score of any domain. Understand a website's overall strength for SEO before building links, writing guest posts, or pursuing partnerships.

What you need to know

What website authority measures Authority scores aggregate backlink quality, quantity, and site health into a single number. Higher = stronger ranking potential and more valuable as a link source.
Use before guest posting Before spending hours writing a guest post, check the target site's authority. Posting on a DA 10 site gives you almost no SEO benefit.
Authority vs. relevance A DA 40 site in your exact niche is often worth more than a DA 70 site in an unrelated industry. Both authority and relevance matter for link value.
Authority changes slowly Building domain authority takes months of consistent link building and content creation. Don't expect quick changes — measure quarterly, not weekly.

Frequently asked questions

What is website authority?

Website authority is a score (typically 0–100) that measures how likely a site is to rank in search results, based primarily on the quality and quantity of its backlinks.

Which authority metric should I use?

Different tools use different metrics — Moz DA, Ahrefs DR, Semrush AS. They all measure similar things. Be consistent and use the same metric when comparing sites.

Is a high-authority site always trustworthy?

Not necessarily. Authority measures SEO strength, not content quality or trustworthiness. Always read the site before pursuing a partnership or backlink.

How do I build website authority?

Earn high-quality backlinks, publish original research and resources, fix technical SEO issues, and consistently create content other sites want to reference.
