Ahrefs DR检查工具免费：2026年您可以获得哪些未付费的服务

A common belief in SEO circles is that Ahrefs' Domain Rating sits behind a paid subscription. For a single lookup that isn't true, and in 2026 there are more free routes to Ahrefs' DR than most people realise.

This guide walks through each of them: what it shows, what it costs you in account setup, and where it stops. It ends with the cases where an open-data alternative is genuinely the better fit, and the ones where it isn't.

The short answer

You can check Ahrefs' DR for free, with no account, on Ahrefs' Website Authority Checker. For DR as you browse, history, or many domains at once, each option below covers a different need.

Option 1 — The Website Authority Checker (no account)

This is the simplest route. Paste a domain, solve any check Ahrefs puts in front of you, and you get the domain's DR straight from Ahrefs' index.

Good for: a one-off number to quote, or checking a single prospect before you pitch.

Where it stops: one domain per search, no history and no list of the links behind the score. Ahrefs points you to a free account or the SEO Toolbar for more.

The same page is also one of the clearest explanations of DR anywhere. Ahrefs lists its calculation in five steps: count unique linking domains, weigh their authority, account for how many unique domains each of them links to, compute a raw score, and plot it on a 100-point scale. It also states plainly what DR leaves out: link spam, traffic and domain age.

Option 2 — The Ahrefs SEO Toolbar (free account)

The Ahrefs SEO Toolbar is a Chrome and Firefox extension. With a free Ahrefs account it shows DR and URL Rating (UR) for the pages you visit.

Good for: vetting many sites in passing, for example while working through a list of guest-post prospects.

Where it stops: it is a browser tool. It can't feed a spreadsheet or a website.

Option 3 — Ahrefs Free for sites you own

Ahrefs Free, formerly Ahrefs Webmaster Tools, gives you Ahrefs data on websites you can prove you own. Verification works through Google Search Console, an HTML file, a DNS record or a meta tag.

Good for: your own site. You see far more than a single number: backlinks, referring domains, organic keywords and a site audit.

Where it stops: unverified sites, which means your competitors. There are also limits on how much you can view and export at once.

If you only care about your own site's DR and the links behind it, this is the most complete free option there is.

Option 4 — The free Domain Rating API

This is the option most people miss. Ahrefs publishes a free Domain Rating endpoint in its API. Requests to it are free, and API keys are free to generate from a free Ahrefs account.

Good for: developers who want Ahrefs' DR inside a dashboard, an internal tool or a spreadsheet script.

The rules that come with it are in Ahrefs' Domain Rating license. In summary:

• Attribution is required. Any display of the data must carry "Domain Rating by Ahrefs" next to it, with a working link to ahrefs.com, and it can't be hidden.
• No substitutes. You can't repackage, sell or distribute the data as a product that substitutes for or competes with Ahrefs.
• No bulk harvesting. Systematically extracting DR to build a competing dataset is prohibited.
• No guarantees. Ahrefs can rate-limit, change or withdraw the API at any time.

Read the license yourself before building anything public on it. This summary is not legal advice, and the terms can change.

Option 5 — A paid Ahrefs plan

A paid plan is the only way to get the full picture for any site: DR history over time, every referring domain, anchor text, competitor analysis and alerts.

Good for: agencies and anyone doing link building as a core part of their job.

Where it stops: cost. For a blogger who checks a handful of domains a month, the free options above cover the need.

Why "free Ahrefs DR checkers" on other sites can mislead

Search "ahrefs dr checker free" and you will find many third-party sites with a box labelled "DR". Before you trust one, ask where its number comes from. There are three possibilities:

1. It calls Ahrefs. Then the license requires a visible "Domain Rating by Ahrefs" attribution with a link. No attribution is a red flag.
2. It uses another dataset and labels the result "DR" because readers recognise the term. That isn't wrong in itself, as long as the site says so clearly.
3. It doesn't say. Treat the number as unknown.

FeedPulse falls into the second group, and we say so on every result: our DR checker reads the open Open PageRank dataset, built from the public Common Crawl web graph, and rescales its 0-10 score linearly to 0-100. It is a DR-style equivalent, not Ahrefs' figure.

When an open-data alternative is the better fit

There are honest reasons to use a non-Ahrefs score, and honest reasons not to.

It fits when:

• You want a public badge that shows your own site's authority and refreshes on its own. Our DR badge is free to embed, and every score comes from a published, open method you can check.
• You want a long-run trend from one consistent method. Open PageRank keeps monthly history back to 2018 and anchors each release to the last.
• You don't want an account. Our checker works without signup.

It doesn't fit when:

• Someone asks for your Ahrefs DR by name. A sponsor, marketplace or outreach partner with a "DR 30+" rule means Ahrefs' number. Give them Ahrefs' number.
• You need the links behind the score. An open-data score is a single number. For the referring domains behind it, use a backlink tool such as our backlinks counter or Ahrefs Free on your own site.

Why your DR differs between tools

Even two honest tools disagree, for three structural reasons:

• Different crawls. Ahrefs runs its own crawler; Open PageRank uses Common Crawl; Moz and Semrush run their own. Each finds a different slice of the web's links.
• Different maths. Each weighs link quality, breadth and dilution differently, and each normalises onto its own scale.
• Different timing. Each refreshes on its own schedule, so a link you earned last week can show up in one tool and not yet in another.

For that reason, compare sites using one tool at a time, and keep your own trend in one tool. Mixing an Ahrefs DR for one competitor with an open-data score for another produces a comparison that means nothing.

Which free option should you use?

Match the tool to the job:

• "What's this one site's DR?" Use the Website Authority Checker. No account, one result, done.
• "I'm vetting a list of prospects." Install the SEO Toolbar with a free account and read DR as you open each site.
• "How strong is my own site, and why?" Verify it in Ahrefs Free. You get the links behind the number, not just the number.
• "I want DR in my own dashboard." Use the free DR API, and build the attribution in from the start.
• "I want a badge on my site that updates itself." Use an open-data badge such as ours, labelled honestly, or display Ahrefs' DR with the required attribution.
• "I do link building for clients every week." That is what the paid plans are for.

Most bloggers and indie makers only ever need the first three, and all three are free.

A checklist before you quote a DR number

DR numbers end up in pitches, media kits and sponsorship decks, where a wrong figure costs credibility. Before you quote one:

1. Name the source. "DR 34 (Ahrefs, October 2026)" is a fact. "DR 34" on its own invites the question of which tool you used.
2. Use the same tool as the person asking. A sponsor with a "DR 30+" rule is almost always using Ahrefs.
3. Date it. DR moves as the crawl moves. A number from last year can be well off today.
4. Don't round up. If the tool says 29, say 29.
5. Re-check before you publish. A two-minute lookup on the day beats a remembered number.

How do I raise my Ahrefs DR?

Earn followed links from more unique, reputable websites. Ahrefs states that getting backlinks from more referring domains is the only way to improve DR, and that improving DR shouldn't be your primary goal. Focus on links from relevant sites to the pages you want to rank, and the score follows.

Is the Ahrefs Website Authority Checker really free?

Yes. Ahrefs offers it as a free tool on its website, and it returns the domain's Domain Rating from Ahrefs' index without an account. Deeper data, such as the list of linking domains, needs a free Ahrefs account or a paid plan.

Is there a free Ahrefs DR API?

Yes. Ahrefs documents a free Domain Rating endpoint that works with a free API key. Using the data means agreeing to the Domain Rating license, which requires a visible "Domain Rating by Ahrefs" attribution with a link and prohibits products that substitute for Ahrefs.

Can I show my Ahrefs DR on my website?

The license allows you to display DR data as long as the attribution "Domain Rating by Ahrefs", linked to ahrefs.com, sits next to it and isn't hidden. If you prefer a badge that refreshes itself without an Ahrefs key, an open-data badge like ours is an alternative. Label it honestly, since it isn't Ahrefs' figure.

Why is my FeedPulse DR different from my Ahrefs DR?

Because they are computed over different crawls with different maths. Our score comes from Open PageRank, which uses the public Common Crawl graph, rescaled to 0-100. Ahrefs computes DR over its own index. They usually move in the same direction as your link profile changes, but won't match exactly.

Does a higher Ahrefs DR improve Google rankings?

Not directly. DR is Ahrefs' metric, not Google's. Ahrefs itself notes that Google denies using "domain authority" as a ranking factor, while its own correlation studies show DR and rankings tend to move together. Earn links from relevant, genuine sites and DR follows; chasing the number itself rarely helps.
