What the Website Authority Checker does
Every SEO toolvendor has its own authority metric, and they routinely disagree. This checker sidesteps single-metric bias by computing a composite Website Authority score from three inputs: Moz Domain Authority, Google PageRank data, and the number of followed linking domains. Bulk mode covers up to 10,000 domains with export to CSV or Excel.
A composite is harder to game than any single score — domains inflated on one metric (usually via spammy link volume) get pulled back to earth by the others. That makes this the sanity check I run when a site’s DA looks suspiciously high for its apparent quality, and the Spam Score Checker completes the picture.
How to use it
- Reach for the composite when a single metric looks wrong: Run this the moment a domain’s DA looks suspiciously high for its apparent quality; the composite blends three signals a lone score cannot.
- Compare the composite against the signals behind it: The value is the disagreement: line the WA score up against DA, PageRank, and followed domains to see which input is inflated.
- Flag sharp divergence as a manipulation signal: When one metric towers over the rest, that gap usually means bought links propping up a single number. Investigate before trusting the site.
- Pair it with a spam-score pass: Authority tells you how strong a domain looks; spam score tells you how risky it is, and a sound link decision needs both.
- Export the scored list for triage: Bulk-score a prospect list or your own domain portfolio and keep the CSV for periodic re-checks.
DA vs Page Authority vs Spam Score: what each signal measures
The composite Website Authority score blends signals people constantly confuse. Here is what each one actually measures, so you know why a composite is harder to game than any single number.
| Signal | Scale | What it measures |
|---|---|---|
| Domain Authority | 1–100 (log) | Whole-domain ranking potential from its link profile. |
| Page Authority | 1–100 (log) | Ranking potential of a single URL, not the whole site. |
| Followed linking domains | Raw count | Unique sites linking without nofollow — the links that pass authority. |
| Spam Score | 1–100% | Resemblance to domains Google penalized. Higher is worse. |
Metric definitions per Moz’s authority-metrics documentation. A domain inflated on one signal is usually pulled back by the others.
Website Authority Checker FAQ
How is this different from Domain Authority?
DA is one vendor’s metric built from one link index. The Website Authority score blends Moz DA, Google PageRank signals, and followed linking domains into a composite — so a domain gaming one metric still gets exposed by the others.
Why do authority metrics disagree between tools?
Each vendor crawls its own link index and weighs signals differently. Disagreement is normal; sharp disagreement is diagnostic. When one metric is dramatically higher than the rest, investigate before trusting the domain.
What’s the count of followed linking domains and why does it matter?
It’s the number of unique domains linking without a nofollow attribute — the links that pass authority. It’s the hardest input to fake at quality, which is why it anchors the composite score.
