Website DA Checker

What the website DA checker shows

This checker treats a website as more than a score. Alongside Domain Authority, it answers the basic questions you'd ask before trusting, buying or linking to a site.

How to check the DA of any website

1. Copy the website address from your browser bar. It can include https, www, a subdomain or a page path.
2. Paste it into the checker and select Check Website. Add more sites on new lines to check up to 20 at once.
3. Read the profile. Start with DA, then look at age and reputation. A high DA on a months-old domain deserves a second look.

Website DA vs page authority

Website DA describes the whole domain. Page Authority (PA) describes one URL. If you paste a link to a blog post, the website DA checker reports on the site that hosts it, which is usually what you want when judging a website.

When you're weighing a specific page, such as a guest post placement, use the PA checker to compare page-level and domain-level authority.

Subdomains, www and root domains

The checker treats www.example.com and example.com as the same website. Subdomains such as blog.example.com are checked too, and the result shows the root domain's authority, because Ahrefs rates links at the root domain level.

That's worth knowing on free hosting platforms. A site on a shared platform subdomain shows the platform's very high score, which says nothing about that individual site's own links.

When to check a website's DA

• Before buying a website or domain. Pair DA with registration age and blocklist status to spot a rebuilt expired domain.
• Before a guest post or link placement. Confirm the site is live, secure and not flagged.
• During a client audit. A single profile covers authority and basic site health in one screenshot.
• To size up a competitor. Put several sites side by side with the domain comparison tool.

Why website age and DA belong together

Website age shows how long a site has had to earn links, and DA shows how many it earned. A 10-year-old website with DA 12 has grown slowly. A 6-month-old website with DA 45 either went viral or inherited links from a previous owner.

Age here comes from the domain's registration date in the official registry. When a registry publishes no date, the checker uses the first Wayback Machine capture and labels it that way. Our guide to Domain Authority for new websites covers what to expect in the first years.
