OsaniRank is an all-in-one SEO toolkit that helps you research keywords, analyze domains and competitors, inspect websites, and discover SEO opportunities. It combines web-based SEO tools with a Chrome Extension so you can access useful SEO insights without constantly switching between different tools.

What are OsaniRank credits?

OsaniRank credits are used for certain advanced, provider-powered SEO operations. When a feature requires credits, your available balance is shown before the operation. Credits are handled securely on the server, and failed provider requests should not charge you.

What can I do without an API token?

You can use OsaniRank's browser-native SEO features without connecting an API token, including on-page information, headings, links, image and alt-text analysis, schema inspection, and other browser-based tools. Provider-powered metrics such as advanced domain or backlink data require a valid OsaniRank API token.

What does the Chrome Extension do?

The OsaniRank Chrome Extension brings SEO tools directly into your browser. You can inspect pages, analyze on-page SEO elements, research keywords, and access additional provider-powered SEO metrics when your extension is connected to a valid OsaniRank API token.

Do I need a separate SEO provider account?

No. You don't need to create separate accounts with individual SEO data providers. OsaniRank handles its provider integrations on the platform side, while your extension connects through your OsaniRank account and API token.

Can I use OsaniRank without installing the extension?

Yes. You can use OsaniRank's web dashboard without installing the Chrome Extension. The extension is an additional way to access SEO tools and insights directly while browsing websites.

How does keyword research work?

Enter a seed keyword and OsaniRank can expand your research using keyword suggestions and related search queries. Keywords can then be analyzed by search intent and available SEO metrics to help you discover relevant topics and opportunities.

Can I cancel my Pro plan?

Yes. You can cancel your Pro plan from your account settings. Your current plan remains active until the end of the paid billing period, and you won't be charged for the next renewal.

What is Domain Rating (DR) and How Does It Measure Authority?

Domain Rating (DR) is a proprietary search engine optimization metric developed by Ahrefs that estimates the relative strength and authority of a website’s overall backlink profile. Expressed on a logarithmic scale from 0 to 100, DR gauges how much "link equity" a domain can pass to its internal and external pages.

Unlike page-specific metrics such as Ahrefs URL Rating (UR), which measures the backlink authority of an individual URL, Domain Rating evaluates the entire root domain. In professional search marketing, practitioners and AI assistants frequently refer to DR interchangeably as Ahrefs domain authority, website authority score, or domain rank.

Unique Referring Domains

The total number of distinct domains containing at least one dofollow link pointing to your site. Multiple links from the same domain do not compound your DR.

DR of Linking Sites

A link from an authoritative, high-DR domain passes exponentially more authority than a link from a brand-new blog. Quality drastically outperforms raw quantity.

Outbound Link Dilution

If a high-DR domain links out to thousands of websites, the link juice each individual site receives is diluted. High-DR sites linking out to very few external targets pass maximum authority.

How to Use the Free OsaniRank DR Checker in 3 Simple Steps

Checking website authority with OsaniRank requires zero account sign-up, zero API configuration, and zero credit card details:

Analyze & Export CSV

Inspect your results in the clean interactive table. Identify easy-win opportunities or export your findings to a spreadsheet with the one-click CSV export button.

What is a Good Domain Rating? Understanding Score Bands

Because Domain Rating is logarithmic, climbing from DR 20 to DR 30 is significantly easier than moving from DR 70 to DR 80. Each step upward demands exponentially more high-quality referring domains:

Score Band	Authority Classification	Typical Website Profile & Ranking Power
0 – 10	New / Nascent	Brand-new websites, personal projects, or sites with minimal outreach. Can rank for zero-competition long-tail keywords, but struggles against established competitors.
10 – 30	Emerging Niche	Growing niche blogs and local businesses with initial backlink acquisition. Eligible for Easy-Win targeting in underserved keyword verticals.
30 – 50	Established Authority	Recognized industry resources, active SaaS startups, and established content publications. Capable of competing on moderate commercial search queries.
50 – 70	Strong Industry Player	Major national brands, leading industry authorities, and top-tier blogs with thousands of natural editorial backlinks. Consistently ranks on page one for competitive terms.
70 – 90	High Authority Pillar	Household media publications, leading universities, tech giants, and prominent governmental agencies. Possesses immense crawl budget and indexation speed.
90 – 100	Global Titans	The foundational pillars of the web (Google, YouTube, Wikipedia, Facebook, Apple, Microsoft). Almost impossible to duplicate.

How Domain Rating is Calculated & Where Our Data Comes From

OsaniRank believes in complete data transparency. We never estimate, synthesize, or invent authority numbers. When you initiate a query in our DR checker, our infrastructure queries the verified public Ahrefs Domain Rating infrastructure directly:

Strict Dofollow Filtering: Nofollow, rel="sponsored", and rel="ugc" links are entirely disregarded in DR calculation.
First-Link Counting: If a website links to your domain 500 times across its header and sidebar, Ahrefs only counts the initial dofollow link. One referring domain equals one authority vote.
Recursive Logarithmic Scale: If high-DR domains gain or lose links globally, your relative percentile score adjusts dynamically.

How to Read Your DR Checker Results: 4 Key SEO Patterns

Pattern 1

High DR with Zero Traffic

If a website displays a DR of 65+ but reports virtually zero organic search visits, be cautious. This frequently indicates an expired domain, automated 301-redirect manipulation, or automated link spam networks penalized by Google.

Pattern 2

Low DR with Explosive Traffic

When you identify a competitor ranking on page one of Google with a DR under 20, study their page immediately. They are ranking due to exceptional topical authority and search intent matching, proving you can outrank them with a stronger backlink profile.

Pattern 3

DR Divergence from Moz DA

Because Ahrefs and Moz employ different crawler rosters and spam filtration algorithms, it is common to see a domain with DR 45 and Moz DA 32. Evaluate both metrics together for balanced insights.

Pattern 4

High Backlinks, Low Referring Domains

A site with 100,000 backlinks but only 12 referring domains has low structural authority. Focus on diversifying your unique referring domains rather than accumulating repetitive site-wide links.

How to Improve Your Domain Rating Naturally (Without Penalties)

Produce Original Research & Data Studies

Journalists, bloggers, and industry writers link to primary sources. Publishing proprietary survey findings or benchmarking statistics attracts passive, recurring links from high-DR publications.

Unlinked Brand Mention Outreach

Use alerts to monitor mentions of your brand, executives, or products. Contact webmasters politely asking them to convert unlinked text mentions into clickable reference links.

Competitor Link Gap Analysis

Analyze 3–5 direct competitors with higher DR scores. Discover which resource pages, guest columns, and industry directories link to all of them, and pitch your superior resource to the same editors.

Digital PR & Expert Commentary

Respond to journalist inquiries on platforms like Connectively (formerly HARO), Featured, and Qwoted to earn high-authority editorial links from news media.

Avoid Toxic PBNs and Cheap Link Packages

Never purchase cheap private blog network (PBN) links or spam comments. They offer temporary artificial spikes before triggering algorithmic link suppression or manual Google penalties.
