DR Checker

DR Checker is a free domain authority lookup tool that mainly provides lookup and comparison capabilities around Domain Rating (DR) and Domain Authority (DA)/Page Authority (PA).

Purpose This tool is used to view the current Domain Rating observation for a public website, or to compare multiple domains sequentially in bulk. It also provides a free DA PA checker for looking up any website's Domain Authority and Page Authority, checking up to 10 URLs in bulk at a time. The tool clearly distinguishes statuses such as current, expired, unavailable, and provider failure, and results depend on available third-party providers.

Main capabilities

1. Single-domain DR lookup: enter a public domain (for example, ahrefs.com) to get the currently available Domain Rating observation from the provider.
2. Bulk DR comparison: compare multiple domains sequentially; the larger the domain list, the longer it takes; unavailable, expired, and provider failure remain as separate result statuses.
3. DA PA check: use Moz data to check the Domain Authority and Page Authority of up to 10 URLs at a time.
4. Stored DR history and badge: eligible Domain Listings can view stored DR history and copy optional badge embed code; the badge shows the latest stored DR of the matching listing and links back to its public page.
5. Related metric display: some check results show monthly visits, bounce rate, pages per visit, main traffic sources, number of referring domains, and top linking sites.
6. Auxiliary metric comparison: the page also lists related website metrics such as Domain Authority (DA), Trust Flow (TF), Spam Score, Referring Domains, and Traffic Checker, and explains their respective providers and limitations.

How to use

• Single lookup: no account required; enter a public domain to request the currently available Domain Rating observation.
• Bulk lookup: compare multiple domains sequentially in Bulk mode.
• DA PA check: use the free DA PA checker to check up to 10 URLs in bulk.
• Input suggestion: use the root domain (such as ahrefs.com) instead of a subdomain, the tool automatically normalizes the www and https prefixes.
• Badge embedding: eligible Domain Listings can copy an optional badge embed code.

Use cases

• Track link-building progress: record comparable DR observations, and check for new and lost links, then determine whether changes are related to your own work.
• Analyze competitors: use domain-level DR as one clue, while also comparing actual ranking pages, search intent, content, and page-level links.
• Evaluate link opportunities: use DR to prioritize link candidates, then check the specific page, topical relevance, audience, editorial placement, and outbound links.
• Detect negative changes early: DR changes may reflect lost or newly discovered links, changes in linking domains, outbound distribution, or provider recalculation, and do not prove a Google penalty.
• Screen before buying a domain: use DR as one screening clue, then verify ownership, traffic, links, penalties, trademarks, and revenue.
• Display badges: use an optional badge to show the latest stored DR for a matching Domain Listing.

Limitations and caveats

• DR is Ahrefs' relative 0–100 metric used to measure the strength of a website's backlink profile, taking into account the strength of linking domains and how their links are distributed; DR is not a Google ranking factor.
• The DR checker returns the observations currently available from the provider, not Ahrefs' full backlink product.
• Observations in the middle range have no universally good or bad meaning; they need to be compared with relevant peers using the same provider and the same period, and the underlying links should be checked.
• DR uses a logarithmic scale, so going from 20 to 30 is far easier than going from 70 to 80; each point of increase represents a significant jump in link authority.
• A high observation means a stronger backlink profile in Ahrefs' relative model, and no single range should be regarded as universally strong.
• DR measures domain-level authority, while URL Rating (UR) measures page-level authority; a page on a high-DR site may have a low UR because it has few backlinks.
• DR is not equal to traffic, and high DR does not guarantee traffic; DR measures link authority, not content quality or user engagement.
• DR can decline, due to reasons including losing high-quality backlinks or linking domains themselves declining in DR.
• DR changes occur only after the provider discovers and recalculates the relevant link graph; there is no fixed timeline, and a score change by itself cannot prove that a particular marketing campaign caused the change.
• Results depend on third-party providers and may be outdated or unavailable; full backlink research, indexing, filtering, exporting, or historical records require a dedicated product.
• Badges are link metric displays, not identity, security, or official Ahrefs verification seals.
• Spam Score can help prioritize review, but it cannot prove that a link is harmful or by itself serve as the basis for disavowing links.
