Free AI SEO Domain Authority Checker

Use the score as a comparison, not a verdict

Check your own domain and a small set of genuine search competitors under the same conditions. The estimate is most useful for spotting a large authority gap or tracking broad movement over time. Small score differences should not decide a content or link-building investment on their own.

A stronger link-based authority signal can make a domain more competitive, but rankings still depend on the query, page quality, search intent, technical access, internal links, freshness, and many other systems. AI-assisted search adds more distinctions: crawler access, retrieval, mentions, citations, and human referral visits are separate events.

How to read the estimated authority percentage

A lower result suggests the domain has a weaker link-authority signal in the provider dataset. Focus on a trustworthy website foundation, useful original resources, relevant mentions, and links earned from real relationships or publications. Avoid buying low-quality links merely to move a third-party metric.

A middle result can support realistic long-tail and niche opportunities. Compare the pages that already rank for the exact query, then improve the page that best matches the intent. A higher result provides a stronger starting point, but it does not rescue an inaccessible, outdated, duplicated, or unclear page.

Authority and AI discoverability solve different questions

This checker asks: how strong does the domain's external authority signal appear? A full TruboRankAI scan asks whether public pages are reachable and understandable: response behavior, robots rules, sitemap discovery, AI crawler access, Markdown and Link headers, content structure, AEO, and GEO signals.

That distinction creates a useful next step. If authority is weak, build genuine source value and earn relevant recognition. If authority is reasonable but impressions or AI visibility remain weak, inspect technical access, query-to-page alignment, direct answers, entities, evidence, and internal linking. Most websites need some work in both areas.

A practical three-step workflow

1. Estimate authority. Record this result with the date and compare only like-for-like domains.
2. Diagnose discoverability. Run the full website scan to find crawl, machine-readable, AEO, GEO, and content gaps the authority estimate cannot show.
3. Prioritize with evidence. Use owned Search Console performance and supported crawler activity in the TruboRankAI platform where those signals answer the next decision.

Frequently asked questions

Is this Moz Domain Authority?

No. Domain Authority is a Moz trademark and metric. This tool uses Open PageRank data to produce a separate estimated authority percentage.

Is the estimate a Google ranking factor?

No. Google does not use this displayed percentage. Treat it as a third-party comparison signal, not a direct ranking score.

Can a low-authority site appear in AI answers?

Yes. A clear, relevant, accessible page can be selected for a specific or underserved question. Authority may affect competitiveness, but a score alone does not determine retrieval or citation.

What should I do after checking authority?

Run the full discoverability scan, review the highest-dependency issue, and connect Search Console or AI Bot Tracking only when you need that evidence. Improve one important public page, deploy, and measure the result.

Methodology and limitations

TruboRankAI requests the domain's Open PageRank decimal score, constrains it to a 0–10 range, and displays it as a 0–100 estimate. The authority signal is not included in the primary technical-readiness score. Provider coverage, refresh timing, and link data can differ from other tools, so retain the provider and date when comparing results.
