Check Your Domain Authority

What Is a Domain Authority Score?

A domain authority score is a number between 0 and 100 that estimates how likely a website is to rank well in search engine results. The higher your score, the stronger your site is considered in terms of trust, technical health, and content quality.

The concept was first popularized by Moz, which created the Domain Authority (DA) metric in the early 2010s. Since then, other tools have introduced their own versions — Ahrefs has Domain Rating (DR), Semrush has Authority Score (AS), and now Rankeo has its own Authority Score that goes a step further.

What makes these scores different from each other? Each tool uses a different formula and a different set of signals. Moz focuses heavily on backlink profiles. Ahrefs looks at referring domains and link strength. Semrush blends backlinks with organic traffic data. These are all valuable perspectives, but they share a common limitation: they measure traditional SEO signals only.

The Rankeo Authority Score measures five dimensions instead of focusing on backlinks alone. It evaluates your technical health, content quality, structured data implementation, trust signals, and — uniquely — your visibility on AI search engines like ChatGPT, Perplexity, and Gemini. This makes it the first authority metric designed for the era where people search on both Google and AI.

It is important to understand that no authority score is used directly by Google as a ranking factor. Google has confirmed this repeatedly. These scores are predictive tools — they estimate your ability to compete based on observable signals. Think of them as a health check for your website, not a guarantee of rankings.

How Is the Rankeo Authority Score Calculated?

The Rankeo Authority Score is a composite metric built from five weighted dimensions, each measuring a different aspect of your site's strength.

Technical SEO (20% of your score)

Covers the foundation of your website. This includes whether you have HTTPS enabled, how fast your pages load, whether your site is mobile-friendly, and whether you have essential files like robots.txt and a sitemap.xml in place. A site that loads in under 2 seconds with proper SSL will score significantly higher than one that takes 5 seconds and runs on HTTP.

Content Quality (20% of your score)

Looks at the substance of your pages. Are your title tags unique across your site? Do all pages have meta descriptions? Is there a proper heading structure with H1 tags? How long is your content on average? Your internal linking structure also matters — a well-connected site signals to search engines that your content is organized and comprehensive.

Structured Data (20% of your score)

Measures how well your site communicates with search engines using schema markup. JSON-LD structured data helps Google and other engines understand exactly what your content is about. Sites with Organization schema, WebSite schema, and BreadcrumbList markup consistently outperform those without it. Use our Schema Validator to check whether your site has the right structured data in place.

AI Visibility (25% of your score)

What makes Rankeo different from every other authority checker. This dimension measures whether AI search engines — ChatGPT, Perplexity, Gemini, Claude, and Grok — mention, recommend, or cite your brand when users ask relevant questions. In 2026, millions of people use AI instead of Google to find recommendations, compare products, and discover services. If your site is invisible to these engines, you are missing an entire channel.

Trust Signals (15% of your score)

Captures indicators that suggest your site is legitimate and established — SSL certificate, domain age, social profiles linked in schema markup, and Organization schema presence.

Why Domain Authority Matters in 2026

1. It helps you benchmark against competitors. If the top-ranking sites in your industry score between 60 and 75, and your site sits at 35, you know there is a gap to close. Use our Domain Compare tool to see exactly where you stand against specific competitors.
2. It helps you prioritize what to fix. A site with excellent content but poor technical health needs different attention than a site with great speed but no structured data. The dimensional breakdown tells you exactly where your weaknesses are.
3. Your authority on AI engines is now as important as your authority on Google. A growing percentage of product research, service comparisons, and local business discovery now happens through AI assistants. If someone asks ChatGPT a question about your industry and you are not mentioned, you have an AI visibility problem that traditional SEO alone cannot solve.

What Is a Good Authority Score?

Rather than chasing a specific number, compare your score to the top-ranking sites for your target keywords. If you are within 10 to 15 points of your competitors, you are in a competitive range. Use our Domain Compare tool to benchmark directly.

Keep in mind that authority grows logarithmically. Moving from 20 to 40 is much easier than moving from 60 to 80. Early improvements happen quickly, while gains at higher levels require more sustained effort.

Domain Authority vs. AI Visibility: Why You Need Both

Traditional domain authority metrics were built for a world where Google was the only search engine that mattered. That world still exists, but it now shares space with a new one. AI search engines like ChatGPT, Perplexity, Gemini, Claude, and Grok answer questions by synthesizing information from across the web. They do not use backlink counts to decide what to recommend. Instead, they look for clear, structured, authoritative content that directly addresses user questions.

This means a website can have excellent traditional domain authority and still be completely invisible to AI engines. The reverse is also true: a site with mediocre backlinks but comprehensive topical coverage and clear structured data can get cited by AI engines regularly.

The practical implication is straightforward. In 2026, you need both. The Rankeo Authority Score weighs AI visibility at 25% — slightly more than any other single dimension — because AI search is not a future trend; it is happening now.

How to Improve Your Authority Score

1. Fix your technical foundation first. Enable HTTPS if you haven't already. Compress images, enable caching, and aim for page load times under 2 seconds. Create and submit a sitemap.xml. Make sure your robots.txt file exists and is configured correctly. Ensure your site is fully responsive on mobile.
2. Strengthen your content. Write unique, descriptive title tags for every page. Add meta descriptions that accurately summarize each page. Use a clear heading structure — one H1 per page, logical H2s and H3s. Aim for 800 to 1,000+ words on important pages. Build internal links between related pages.
3. Implement structured data. At minimum, add Organization schema (name, logo, URL, social profiles), WebSite schema (with SearchAction), and BreadcrumbList. If you publish articles, add Article schema. If you sell products, add Product schema. Our Schema Validator checks your implementation instantly, and the Schema Generator creates perfect markup in one click.
4. Build AI visibility. Create a /llms.txt file that tells AI crawlers who you are and what you do. Ensure your content answers conversational questions your audience asks. Cover your topic comprehensively — AI engines favor deep expertise over shallow coverage.
5. Accumulate trust over time. Link your social media profiles in your schema markup. Keep your domain registration current. Publish regularly. Get mentioned on reputable sites through partnerships and contributions.

How Often Should You Check Your Authority Score?

Your authority score does not change overnight. Most signals evolve gradually over weeks and months.

A good cadence is to run a full authority check once a month, and after any significant changes — a redesign, new content section, adding structured data, or fixing technical issues. For AI visibility specifically, more frequent monitoring is valuable because AI engine responses can shift within days when competitors publish new content.

Free Authority Check vs. Full Audit: What You Get

If the free check reveals a score you are happy with, great. If it reveals gaps, a full audit tells you exactly what to fix and in what order.
