How it works
Enter your domain and the workflow runs four checks in one go. The authority metrics come from our copy of Moz's link index: Domain Authority, spam score, Page Rank, backlink and linking-domain counts, and the monthly Domain Authority history. Traffic is estimated from your Google rankings via the Keywords Everywhere API. The on-page section fetches your homepage and scores it across the same six categories as our SEO Analyzer. It then lists the fixes in priority order.
What the numbers are. Domain Authority, Page Rank, and spam score are computed by third parties. They are useful for comparing sites, and they are not Google ranking factors. Estimated traffic comes from search volume and the click-through rate for each position, so compare it between sites rather than against your analytics. The on-page score reflects our own list of checks, not a Google score.
What it costs. Nothing. Each run uses one domain lookup, one traffic lookup, and one page audit from your free daily allowances, which reset every day. Paid plans get higher daily caps.
New or tiny domains. If a domain is not in the link index yet, the authority sections show a friendly note instead of numbers. The traffic and on-page sections still run.
What you will see
- Domain Authority (DA)
- Moz's 0 to 100 prediction of how well a domain competes in search. Useful for comparing sites. Not a Google ranking factor.
- Spam Score
- Moz's 0 to 100 estimate of how much a site's profile looks like penalized sites. Low is 0 to 30, Medium 31 to 60, High 61 and up.
- Page Rank
- A 0 to 10 authority score from an independent crawl of the public link graph.
- DA history
- Up to several years of monthly Domain Authority readings, drawn as a trend line, so you can see the direction and not just today's number.
- Backlinks / Linking Domains
- The total links pointing at your site and the number of distinct domains they come from. Each has a followed count, the links that pass authority.
- Link Propensity
- Moz's estimate of how naturally a site attracts links, as a percentage.
- Est. Monthly Traffic
- A computed estimate. For each ranking keyword, search volume times the typical click-through rate for that position, added up.
- On-Page score
- A 0 to 100 score across content, technical, performance, mobile, social, and off-page checks on your homepage. The failed and warning checks are listed as fixes.
Frequently asked questions
What does a website health check include?
Four things in one run. Your authority metrics: Domain Authority, spam score, and Page Rank. Your link profile: backlinks and linking domains with followed counts, plus the Domain Authority trend over time. Your estimated organic traffic and total ranking keywords. And an on-page audit of your homepage with a ranked fix list.
Is this website health checker free?
Yes. The whole report runs free, with no signup and no credit card. Free visitors get a daily allowance of lookups, shared with our standalone tools, that resets every day. Paid Keywords Everywhere plans get higher daily caps.
What is a good Domain Authority score?
It depends on your niche. New sites start near 1. Most small business sites sit between 10 and 30. Established publishers reach 50 to 70, and only giant platforms pass 90. The useful comparison is against the sites that outrank you, not against a fixed number. Your own trend over time tells you more than any single reading.
Is Domain Authority a Google ranking factor?
No. Domain Authority is Moz's metric, and Google has said many times that it uses nothing like it. It stays useful as a shorthand for link strength when comparing sites. That is why we show it next to the metrics that do come from your actual rankings.
Why is my traffic estimate different from Google Analytics?
The estimate is computed from your Google rankings. For each keyword we multiply its search volume by the typical click-through rate for your position. It covers organic Google traffic only. It leaves out direct visits and other channels, and it uses averages. Use it to compare sites and track direction, not as a replacement for analytics.
What does the on-page score mean?
We fetch your homepage and run it through the same checks as our SEO Analyzer: content, technical, performance, mobile, social, and off-page. The results are weighted into one 0 to 100 score with a letter grade. The "what to fix first" list shows the failed and warning checks sorted by severity. The link to the full SEO Analyzer report shows every check.
Why does it say authority metrics are not available?
Very new or very small domains may not be in the link index yet. Some domains have not been crawled recently enough to carry metrics. The traffic and on-page sections still run for them. Indexes refresh on their own schedule, so check back after your site has earned a few links.
Can I share or export the report?
Yes. The page URL becomes a shareable link when the report loads and keeps working for 30 days. Each section has Copy, which pastes straight into Google Sheets or Excel, plus CSV and Excel downloads. The exports include the full Domain Authority history and every on-page finding.
