DA / PA Checker — Domain & Page Authority

What are Domain Authority and Page Authority?

Domain Authority (DA) is a 0–100 score that predicts how well an entire website can rank in search results — higher is stronger. Page Authority (PA) is the same idea for a single page rather than the whole domain. Both are comparative metrics: they are most useful when you benchmark your site against competitors, not as an absolute guarantee of rankings. Google does not use DA or PA directly; they are third-party estimates of overall link authority.

How it works

1. Enter one domain or URL per line — for example yoursite.com and a few competitors.
2. The tool looks up each domain's real authority score and global rank from live link-graph data.
3. The raw authority index (0–10) is scaled to a familiar 0–100 Domain Authority number.
4. Page Authority is derived from that domain authority plus each URL's crawl depth and HTTPS status.
5. You get a ranked comparison table and chart — sorted strongest to weakest — so gaps are obvious at a glance.

What it checks

• Domain Authority (DA 0–100) — overall site strength, scaled from real link-graph authority data.
• Page Authority (PA 0–100) — estimated authority of the specific URL you enter.
• Authority index (0–10) — the raw authority score behind the DA number.
• Global rank — where the domain sits among all ranked sites worldwide.
• Domain age & HTTPS — supporting trust signals for single-domain lookups.
• Bulk comparison — up to 20 domains side by side, sorted by authority.

Common use cases

• Competitor benchmarking — see how your authority compares to rivals before you plan content or links.
• Link prospecting — screen potential linking sites so you spend outreach effort on stronger domains.
• Guest-post vetting — quickly judge whether a site offering a backlink actually has authority.
• Progress tracking — watch your DA trend upward as your backlink profile grows.
• Buying domains — check the authority of an expired or aftermarket domain before you buy.

Example

Enter your domain plus three competitors. The tool might return your site at DA 24, two rivals at DA 41 and DA 58, and a fourth at DA 12. Now you know exactly which competitors out-rank you on authority and by how much — a clear signal to prioritize link building, and a realistic view of which SERPs you can compete in today.

Frequently asked questions

Is the DA / PA Checker free?

Yes. It is completely free and needs no signup. It runs on real link-graph authority data rather than a paid API, so there are no per-check credits to buy.

How are DA and PA calculated?

Domain Authority is derived from a real authority index built on the web's link graph, then scaled to a familiar 0–100 range so it is easy to read and benchmark. Page Authority applies the same idea to a single URL, factoring in crawl depth and HTTPS. Both are independent, comparative estimates of link authority — a practical, no-cost way to size up any site.

Is the data real?

Yes. Domain Authority and global rank come from live link-graph data, not random numbers. Page Authority is a transparent composite of that real domain authority and page-level signals, because free page-level authority indexes don't exist.

Why is my Domain Authority low?

Authority is driven mainly by the quantity and quality of other sites linking to you. New domains, sites with few backlinks, or sites linked only from low-authority pages score lower. Earning links from trusted, relevant sites is the reliable way to raise it — verify who links to you with the Backlink Checker / Verifier and find new prospects with the Link Intersect / Backlink Gap.

How many domains can I check at once?

Up to 20 domains or URLs in a single run — one per line. Results are sorted from highest to lowest authority so the leaders and laggards are instantly clear.

Does a high DA guarantee I will rank?

No. DA and PA are useful relative signals, but Google ranks pages on relevance, content quality, intent match and hundreds of other factors. Use authority alongside on-page work — study a competitor's full profile with the Site Explorer and check a domain's history with the Domain Age Checker.

How often does the score update?

The underlying authority index refreshes periodically rather than in real time, so authority changes gradually. This tool caches results briefly to stay fast; expect scores to move over weeks as your link profile changes, not day to day.
